6B75A0E607ACCBE49EEB410B2CD32E68.taxon	diagnosis	Diagnosis. This species differs from other members of the Sphex argentatus group in having distinct tubercles on the metanotum, combined with completely hyaline wings except for a slight brown tinge at the apical margin of the forewing in some specimens. Specimens of Sphex sericeus that may have the same color pattern are identifiable by the conspicuous transverse ridges on their propodeum, which are lacking in Sphex carbonicolor. Sphex argentatus and Sphex finschii have a darkened wing base, while Sphex decoratus differs by having orange legs (which are dark brown or black in Sphex carbonicolor).	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

3631624B827FD8BFB0CC4462A196F6F5.taxon	diagnosis	Diagnosis. Sphex decoratus (of which only the female is known) can be recognized by the combination of markedly raised, distinct tubercles on the metanotum, a mostly orange metasoma of which segment II is black, and a plain propodeal surface. Sphex sericeus greatly varies in color and may look superficially similar to Sphex decoratus, but differs in having a markedly ridged propodeal dorsum, whereas that of Sphex decoratus lacks notable ridges.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

F7E9A50BE455C003DF532C5814A3588E.taxon	diagnosis	Diagnosis. This species is well characterized by its wings, which are largely hyaline but darkened at the base. It shares this trait with three other species. One of them is Sphex luctuosus that can be distinguished by claw teeth perpendicularly oriented to the inner margin of the claw, a character of the Sphex resplendens group (as a member of the Sphex argentatus group, Sphex finschii possesses obliquely oriented claw teeth). The second spe cies, Sphex argentatus, is identifiable by its distinctly tuberculate metanotum, while the tubercles are indistinct in Sphex finschii. The third species, Sphex fortunatus, has erect setae that are uniformly silvery on its clypeus, whereas Sphex finschii has black setae.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

D70BFA2C35A42B91B39413A08CDC7294.taxon	diagnosis	Diagnosis. Sphex modestus is unique among the Australian Sphex in the combination of the following characteristics: claw teeth obliquely oriented to inner claw margin, wing membrane with a yellow tinge towards their base, appressed pubescence on clypeus silvery-white interspersed with erect black setae, legs and metasoma entirely black or dark brown, and propodeal enclosure not concealing sculpture. Sphex pretiosus is superficially similar, but, among other things, the color of its erect setae on the clypeus matches that of the silvery and silvery-golden appressed pubescence, whereas the erect setae on the clypeus of Sphex modestus are black.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

Sphex sericeus is unique among its Australian congeners in having three to four broad, continuous transverse ridges on the propodeal enclosure which are even visible through the pubescence. Female specimens of Sphex rugifer, Sphex darwiniensis and Sphex imporcatus possess vaguely similar structures, but those are much finer. Sphex rugifer also has approximately 20 ridges on the propodeal enclosure, while those of Sphex darwiniensis and Sphex imporcatus are discontinuous in the center.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

6ED0CCFF4FE8E990D56F9817DB687ECD.taxon	diagnosis	Diagnosis. Sphex fumipennis is distinguished from almost all other Australian Sphex in having largely dark wings, a black metasoma and silvery-white pubescence on the propodeal enclosure. There is only one other species with similar features, Sphex rugifer, and while most females of this species have a red metasoma, the males as well as some females have a black metasoma like Sphex fumipennis. A reliable characteristic of Sphex fumipennis is that the hindwing becomes almost completely hyaline towards the apical margin (Fig. 16 B), while that of Sphex rugifer is, at least in the distal half, uniformly dark (Fig. 24 A-C). Males of Sphex fumipennis also have a conspicuous fringe of silvery setae near the apex of metasomal sternum VIII (Fig. 16 C), whereas males of Sphex rugifer lack this pubescence (Fig. 24 D).	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

This species (of which only the female is known) is characterized by a black metasoma with a dark blue lustre, extensively yellow wings, and dark pubescence on scutum and propodeal enclosure. Sphex resplendens, which is otherwise similar, has uniformly dark wings. The pubescence on the propodeal enclosure of Sphex modestus is at least partially silvery or yellowish, and its hindwing membrane is missing the yellow tinge. Sphex modestus is also distinguished by the presence of tubercles on its metanotum, even though sometimes they are only faintly recognizable, while in Sphex gilberti the metanotum is plain.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

CEAD291B2D2FF545921C843A3FA5B0C5.taxon	discussion	Discussion. At first, the males and females of this species look quite different. While the habitus of the male matches that of most examined species of Sphex, the female's metasoma is much slenderer and seems longer than that of other species. Nonetheless, they most likely are the same species, as indicated by the following features. One of the most important characters that connect both sexes is the uniformly silvery pubescence on the clypeus. In at least six of the ten other Australian species in the Sphex resplendens group, the erect setae on the clypeus are black. Of the remaining four species, two are colored bright orange. One of the other two has extremely unusual structures on the clypeal surface. Concerning the last remaining species other than Sphex gracilis, male and female individuals were found that have both silvery and golden pubescence on the clypeus as well as on the propodeum, a unique trait among the studied material. Moreover, this is also the only species in the Sphex resplendens group where some males and females (see below for explanation) have the wing membrane entirely hyaline (excluding the apical margin), even at the base, and without any yellow. Both also have a very similar sculpture on the propodeal enclosure, and they also share the same length, density and orientation of its pubescence. Finally, the collecting localities show that both sexes occur in close proximity (Fig. 18 E). There seems to be some variability among individuals, but they are nonetheless presumed to be of a single species. In both sexes, there are specimens that come from the same collecting series and are distinctively different in their wing coloration. One group possesses brown wing veins and wings that have no hint of yellow (Fig. 18 C), the other group has orange wing veins and (in males) a yellow tinge in the basal half of the forewing membrane (Fig. 18 D).	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

6A9856B61436026AECAECD8BB4E082B1.taxon	diagnosis	Diagnosis. Sphex imporcatus (of which only the female is known) is unique among Australian Sphex in having a remarkably modified clypeus (Fig. 4 E, 19 B). Dorsomedially on the clypeus, there is a deep groove of which the lower rim is encompassed by 5 - 8 markedly arcuate, broad wrinkles that almost reach the free clypeal margin. Furthermore, Sphex imporcatus possesses several distinct transverse ridges on the propodeum, a characteristic it only shares with Sphex sericeus, Sphex darwiniensis and Sphex rugifer. Sphex sericeus, as a member of the Sphex argentatus group, is set apart by having a pair of distinct tubercles on the metanotum and a partially ferruginous metasoma, while the metanotum of Sphex imporcatus lacks tubercles and its metasoma is black. The metasoma of Sphex darwiniensis is bright ferruginous, and Sphex rugifer can be distinguished by having fuscous wings, whereas Sphex imporcatus has hyaline wings with a slight yellow tinge.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

Females of Sphex mimulus are unique among the Australian members of the Sphex resplendens group in having black legs and the first three segments of the metasoma while the apical three segments are bright ferruginous. Sphex decoratus and some females of Sphex rugifer vary among similar colors, but as a member of the Sphex argentatus group, the former has a pair of distinct tubercles on the metanotum, whereas Sphex mimulus, as a member of the Sphex resplendens group, lacks the metanotal tubercles. Sphex rugifer lacks the yellow tinge in the cellular wing area that is present in Sphex mimulus. Until now, the male of Sphex mimulus is the only one in the Sphex resplendens group with a partially orange or yellowish metasoma.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

03018C67993E54B8D6B908F3AD8BC1D1.taxon	diagnosis	Diagnosis. Sphex rugifer differs from other Australian Sphex through a combination of the following characters: uniformly darkened forewing membrane without yellow tinge, hindwing membrane fuscous beyond the cellular area (Fig. 24 A-C), and silvery-white pubescence on the propodeal enclosure. Females can also be identified, in addition to the aforementioned features, in having a red metasoma, though the tone is often very dark. Both sexes of Sphex resplendens differ in having dark pubescence on the propodeum; and in Sphex fumipennis, the distal part of the hindwing membrane is hyaline (Fig. 16 B). Males of Sphex fumipennis also have a conspicuous fringe of silvery setae near the apex of metasomal sternum VIII (Fig. 16 C), whereas males of Sphex rugifer lack this pubescence (Fig. 24 D).	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

Females of Sphex argentatissimus are unique among the members of the Sphex subtruncatus group in combining the following characters: appressed pubescence on clypeus golden, wing membrane without yellow tinge, and pubescence on propodeal enclosure silvery-white. Males differ from those of the other species in possessing, additionally to the aforementioned features, a petiole that is considerably longer than flagellomere II and a conspicuous notch on the apical margin of metasomal sternum VIII. The former feature separates Sphex argentatissimus from Sphex ermineus, of which the petiole is shorter than flagellomere II, the latter one from Sphex cognatus and Sphex formosellus, in which the apical margin of metasomal sternum VIII is pointed.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

67E13E73645757E1D1D08AC4A9610A0B.taxon	discussion	Discussion. The males of this species have very reliable and distinctive features in which they differ from the other Australian Sphex. These features, however, are male sexual characters (free clypeal margin and metasomal sternum VIII) and thus do not help in establishing the sex association. Still, several characters indicate that both males and females belong to a single species. In the Sphex subtruncatus group, there are only two species whose clypeal and propodeal pubescence resembles that of Sphex argentatissimus. One of them, Sphex pretiosus, is easily identifiable in possessing both silvery-white and golden pubescence on the propodeum. The females of the other one, Sphex cognatus, have golden, silvery-golden or silvery pubescence on the propodeal enclosure and are indeed very similar to those of Sphex argentatissimus. However, of the many examined females of Sphex cognatus, none had propodeal pubescence with the conspicuous white tone of silver that is characteristic of the males and females of Sphex argentatissimus. Wing coloration is a similar case. Females of Sphex cognatus usually have a partially yellow tinged wing membrane, but sometimes it is almost entirely hyaline. On the other hand, the wings of Sphex argentatissimus have no hint of yellow at all. Fig. 26 B shows that the males and females of this species occur at least in the same overall region.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

271FDD0CEE7E32174482383C191B43F0.taxon	diagnosis	Diagnosis. Sphex basilicus differs from most other Australian Sphex by the color of its legs, which are orange from the distal half of the femur up to but excluding the claws, while the remaining parts are black or dark brown (sometimes, tarsomeres V are also black). As opposed to other species with orange legs, the metasoma and scutellum of Sphex basilicus are completely black. The males of this species are also recognizable by the shape of metasomal sternum VIII, which, like Sphex bilobatus and Sphex latilobus, carries two prominent lobes that are visible from above. Unlike these two species, where the lobes are the only visible part of sternum VIII and mostly straight, the lobes of Sphex basilicus are conspicuously curved upward, and a large, undivided portion of sternum VIII is also visible (Fig. 27 B).	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

Females of Sphex bilobatus differ from the other Australian Sphex by the following character combination: metanotum without tubercles, metasoma black, wing veins light to dark brown, appressed pubescence and erect setae on clypeus silvery-white, and scutellum convex medially. Males of Sphex bilobatus are also characterized by their metasomal sternum VIII, which consists of two large separate lobes (Fig. 28 B). This character is only shared with males of two other Australian species. One of them, Sphex basilicus, has a single lobe emerging from below the center of the free clypeal margin, is much larger in size and has orange pubescence on the propodeal enclosure, whereas Sphex bilobatus does not have lobes on the free clypeal margin, and its propodeal pubescence is silvery. In the other one, Sphex latilobus, the free clypeal margin is bright orange, while that of Sphex bilobatus is black.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

In the Sphex subtruncatus group, there are eight species of which females are yet unknown or where matching of males and females was first proposed in this study. Sphex brevipetiolus can theoretically be the female of one of them. Of these, only three have wing veins that are not uniformly dark. One of them (Sphex flammeus) has a bright orange metasoma and largely orange legs. The second one (Sphex pretiosus) has a sharp transition between golden and silvery pubescence on the propodeum and, like the former, a petiole that is considerably longer than flagellomere II. Finally, the reasons for ruling out Sphex corporosus are given in the respective discussion.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

The presence of a few dark erect setae on the clypeus combined with partially orange legs (mainly parts of the anterior surface of the foreleg, as seen in Fig. 30 B, and the inner hindtibial spur including pecten) make Sphex caelebs unique among the male Australian Sphex (the female of this species is unknown). The habitus and mesosomal sculpture resemble some Sphex modestus, which possesses an only inconspicuously raised metanotum and dense white or yellowish tufts of setae on the metasomal sterna that are absent in Sphex caelebs.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

In the Sphex subtruncatus group, there are seven species of which males are yet unknown or where matching of males and females was first proposed in this study. In none of these, however, is the leg coloration comparable to Sphex caelebs, and additional characters indicate its status as a separate species. For example, only two of the seven species also have dark erect setae on the clypeus. These two, however, are much larger than Sphex caelebs; one of them, Sphex ahasverus, has darkened wings and golden pubescence on the propodeum and the other one, Sphex corporosus, has an unusually short petiole, the characters that are lacking in Sphex caelebs.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

80C75F89EFC41D5974F4F1C0895502A6.taxon	diagnosis	Diagnosis. Males of Sphex cognatus differ from all other Australian Sphex in combining the following features: two lobes emerge from the center of the free clypeal margin, the entire clypeus is densely covered with pubescence, and the pubescence on the propodeum conceals the sculpture. Females are distinguished from those of similar species by the same characters and additionally in having hyaline wings that are at least partially yellow tinged. By contrast, Sphex ahasverus possesses uniformly darkened wings, and the females of Sphex argentatissimus have no hint of yellow on their wings. Also, the similar Sphex vestitus has a longitudinal impression with slightly raised borders on the posterior half of its scutum, whereas Sphex cognatus has an even scutum.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

DB9478D0F6ED22BC8F811B5CF51671AF.taxon	diagnosis	Diagnosis. Sphex corporosus can be distinguished from most other members of the Sphex subtruncatus group through a combination of the following characters: petiole shorter than flagellomere II and pubescence on propodeal enclosure not concealing sculpture. Presence of these traits is sufficient to identify males, while females of Sphex corporosus resemble those of Sphex brevipetiolus. The former, however, has a flat scutellum (Fig. 32 B) as well as dark erect setae on the clypeus, whereas in the latter the scutellum is convex and only silvery-white erect setae are present on the clypeus.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

DB9478D0F6ED22BC8F811B5CF51671AF.taxon	discussion	Discussion. Save for two other species besides Sphex corporosus, all members of the Sphex subtruncatus group have a petiole longer than flagellomere II. One of them, Sphex ermineus, is set apart by having exceptionally long and dense pubescence on the propodeal dorsum. Of the other one, Sphex brevipetiolus, only a single female is known. This specimen differs in a few features from the specimens that have been designated the females of Sphex corporosus, and partially surpasses them in resemblance to the males of Sphex corporosus. Arguments in favor of pairing males and females of Sphex corporosus are addressed in the subsequent paragraph. The following attributes are shared by Sphex brevipetiolus and males of Sphex corporosus, but not between males and females of the latter: erect setae on clypeus uniformly silvery-white, and scutellum convex and medially impressed. However, the scutellar structure is usually not constant among sexes in the Australian Sphex. On the other hand, Sphex brevipetiolus has several features that differentiate it from both males and females of Sphex corporosus: considerably shorter tomentum on metasomal tergum I, brassy setae on metasomal sterna, and wing veins that are bright orange in the basal half of the wing. For these reasons, males and females of Sphex corporosus are considered to be one species, and Sphex brevipetiolus is treated as a separate one. Lastly, the geographic range of both sexes is also indicative of the status as a single species, particularly since the number of examined individuals was rather large. Males and females were often found in close proximity to each other, or even in the same areas (Fig. 32 C).	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

DB9478D0F6ED22BC8F811B5CF51671AF.taxon	etymology	Etymology. Corporosus is a Latin adjective, meaning " corpulent ". A few members of this species from the ANIC were already labeled with this name, although it is unclear by whom. There are no related publications, but the species will be named Sphex corporosus to minimize the risk of confusion in case there are more specimens already so labeled. It undoubtedly refers to the large size of the species.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

996B450C63B3F5488E7CF02D2C906BB3.taxon	diagnosis	Diagnosis. Females of Sphex flammeus (the male is unknown) differ from other Australian Sphex by the following combination of features: appressed pubescence on clypeus silvery-white, scape, legs and metasoma largely orange, and wing membrane without a yellow tinge. Sphex decoratus, Sphex sericeus, Sphex darwiniensis and Sphex rhodosoma are also largely orange, but they are members of different species groups. Sphex staudingeri differs in having golden pubescence on clypeus and scutum instead of silvery-white one and moderately fuscous wings instead of hyaline ones, while also being considerably larger.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

Based on species group membership, there are eight species of which females are yet unknown or where matching of males and females was first proposed in this study. Sphex flammeus can theoretically be the female of one of them. However, only one of them, Sphex semifossulatus, is also colored bright orange. Still, both differ in the color of scapes and propodeum, as well as in the orientation of the mesosomal pubescence, which is denser and more appressed in Sphex flammeus.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

This species differs from other members of the Sphex subtruncatus group mainly in the color of the wing membrane, which is markedly fuscous near the base and around the subcosta as well as below the submedial cell. This seems to be the only character that differentiates the species from Sphex jucundus, which has the wing mem brane hyaline in this area. The absence of tubercles on the metanotum and the lack of erect dark setae on the clypeus distinguish Sphex fortunatus from Sphex finschii in the Sphex argentatus group, which has similar wing coloration.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

There are seven species in the Sphex subtruncatus group of which males are yet unknown or where matching of males and females was first proposed in this study. Sphex fortunatus can theoretically be the male of one of them. Two of them have a petiole that is markedly shorter than flagellomere II, while two others differ in having pubescence on the propodeal enclosure that is dense enough to conceal the sculpture. One of the three remaining species (Sphex flammeus) is mostly orange in its body color, and another one (Sphex pretiosus) has a mix of golden and silvery pubescence on the propodeum and wing veins that are bright orange in the basal wing half.

70075103DFC77090A14BAC7BE5F75D48.taxon	discussion	Discussion. In this species, males and females closely resemble each other, except for commonly sexually dimorphic characters such as the scutellum. Due to this dimorphism, however, the females are easier to define as a new species than the males. At most, only four other females in the Sphex subtruncatus group are known to have a flat scutellum. Two of those are distinguished in having golden pubescence on the propodeal enclosure, and the petiole of the other two is considerably shorter than flagellomere II. One character was found in which males and females of Sphex jucundus differ from each other and which is usually not a sexually dimorphic feature among Australian Sphex, the density of the pubescence on the propodeal enclosure. However, this argument alone would not be sufficient to demonstrate that they belong to different species. The identical coloration of the wings in males and females as well as the conspicuously dense tomentum both have on their metasomal tergum I are only a few of their shared features. Finally, a great number of males and females come from the same or from nearby localities, which is another indication that both form one species (Fig. 26).	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

8F321894090227A35C6D1C9B6A8AB90E.taxon	discussion	Discussion. Sphex latilobus is clearly an undescribed species. It also seems unlikely that it can be associated with one of the species based solely on females. Within the Sphex subtruncatus group, there are seven species of which males are unknown or where matching of males and females was first proposed in this study. Since most diagnostic characters of this species are suspected to be sexually dimorphic, the number of potential candidates was first narrowed down by eliminating all species where matching of males and females is well-founded (Sphex jucundus, Sphex corporosus and Sphex pretiosus), which leaves four species. One of them (Sphex brevipetiolus) has partially orange wing veins and a petiole that barely reaches the length of flagellomere II; another one (Sphex ahasverus) has dark setae on the clypeus, fuscous wings and golden propodeal pubescence. Of the remaining two, one (Sphex argentatissimus) has a clypeus with golden pubescence; the body of the other one (Sphex flammeus) is mostly bright orange. Thus, Sphex latilobus is unlikely to match any of the currently recognized species.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

013CE6C384496CFF13A422D4A9FEBE05.taxon	diagnosis	Diagnosis. This species is unique among the Australian Sphex in having a more or less sharp transition in the color of the pubescence on the clypeus and the propodeal dorsum. On the ventral part of the clypeus and the outer and posterior margin of the propodeal enclosure, the pubescence is silvery-white; while it is golden on the dorsal part of the clypeus and silvery-golden to golden on the propodeal enclosure. Moreover, the metasomal sternum VIII in males is spoon-shaped and has a gentle notch at the apical margin (Fig. 39 B).	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).

Females of Sphex vestitus can be identified by the pubescence on the clypeus and the propodeal enclosure being golden combined with the wing membrane hyaline, without yellow tinge. A unique character differentiating this species from similar ones (like Sphex cognatus) is a longitudinal median impression on the posterior half of the scutum (Fig. 42 B). Males of Sphex vestitus can be identified by two longitudinal carinae on the metasomal sternum VIII which form a channel-like structure (Fig. 42 C), and also by a single lobe in the center of the free clypeal margin.	en	Doerfel, Thorleif H., Ohl, Michael (2015): A revision of the Australian digger wasps in the genus Sphex (Hymenoptera, Sphecidae).
