03E11B403671FFF6FCEFFEE4FC5BFD20.taxon	discussion	DISCUSSION Following the key to dipteran families of McAlpine (1981), L. eocenica n. sp. falls in the Cecidomyiidae Lestremiinae because of the following characters: vein A 2 absent, R with only two branches, C continuing around wing, first tarsomere longer than second, each tarsus five-segmented, two ocelli present (although some Lestremiinae have no ocelli, see Gagné 1995). After Wood & Borkent (1986, 1989), L. eocenica n. sp. falls in the Cecidomyiidae rather than in Sciaridae, because of the following synapomorphies: presence of an eye bridge (character also present in Sciaridae and Scatopsoidea), tibial spurs absent (see also Gagné 1994) (but character also present in Scatopsidae); setae of flagellomeres arranged in encircling whorls. Gagné (1994) proposed a phylogeny of the Cecidomyiidae, with the Lestremiinae as sister group of all other representatives of the family, but without giving any synapomorphy supporting the clade Lestremiinae. Jaschhof (2000) proposed to consider the Catotrichinae as most basal clade and the Lestremiinae as sister group of the Porricondylinae + Cecidomyiinae, supporting the monophyly of the Lestremiinae by the presence of crenellate whorls in male flagellomeres. L. eocenica n. sp. has two crenellate whorls of long setae, longer than the width of the flagellomere. Thus, we place L. eocenica n. sp. in the Lestremiinae. Following the keys to Nearctic and European genera proposed in Gagné (1981, 1994) and Skuhravá (1997), L. eocenica n. sp. falls in the Lestremiinae Lestremiini because of the following characters: only two ocelli present, tarsi five-segmented, metatarsus distinctly longer than second tarsal segment, M 1 + 2 present, with its fork longer than its stem, legs without scales, macropterous, CuA simple, M 3 + 4 distinct, R 5 more than two-thirds length of wing, 14 (more than six) flagellomeres, each longer than wide, tibiae without disto-ventral spines, Rs shorter than r-m. Jaschhof (1998: fig. 236, characters 7, 8) characterized the Lestremiini after the relative sizes of the scape, pedicel, and flagellomeres. L. eocenica n. sp. has a broad and large scape and pedicel, distinctly broader than its flagellomeres. According to Jaschhof (1998: fig. 237), the phylogeny of the Lestremiini is imperfectly understood. Nevertheless, the genera Anarete Haliday, 1833 and Conarete Pritchard, 1951 can be excluded because of the presence of 14 long-necked flagellomeres, instead of six to eight with short or indistinct stems. Within the Palaearctic and Nearctic faunas, the presence of two crenellate whorls on flagellomeres excludes affinities with genera other than Lestremia Macquart, 1826 and Anaretella Enderlein, 1911 (Gagné 1981; Skuhravá 1997). The absence of digitate flagellomere sensoria (also excluding affinities with Allaretella Meyer & Spungis, 1994), the parameres very narrow in distal portion, together with M 3 + 4 with proximal end close to M, well before level of r-m, exclude the genus Anaretella and are characters diagnostic of recent Lestremia (Edwards 1938 a; Meyer & Spungis 1994; Skuhravá 1997; Jaschhof 1998). After Mani (1935, 1945), the Indian genus Neolestremia Mani, 1935 (two species N. boerhaaviae Mani, 1935 and N. longipalpsa Deshpande, Shaikh & Sharma, 2002) has a three-segmented palpus, instead of a four-segmented palpus in Lestremia and in L. eocenica n. sp.	en	Nel, André, Prokop, Jakub (2006): New fossil gall midges from the earliest Eocene French amber (Insecta, Diptera, Cecidomyiidae).

03E11B403674FFF4FCEEFCC1FBFAFC06.taxon	discussion	DISCUSSION For the same reason as Lestremia eocenica n. sp. above, L. deploegi n. sp. falls in the genus Lestremia. L. deploegi n. sp. differs from L. eocenica n. sp. in its simple gonostylus, and also the nodes of flagellomeres slightly shorter than the necks, instead of being distinctly longer. This character of L. deploegi n. sp. is also present in the recent Lestremia species and in the Baltic amber L. pinites (Kieffer 1913; Jaschhof 1998). Also, the eyes of L. deploegi n. sp. meet dorsally at only one point, unlike those of L. eocenica n. sp. and in the recent Lestremia species in which the eye-bridge is three or four facets broad (Edwards 1938 a: 25). Nothing is known about the eye-bridge of L. pinites, but Meunier (1904) indicated that the male fourth palpal segment of this last species is 1.3 as long as its third palpal segment. In L. deploegi n. sp., the fourth palpal segment is 1.7 as long as the third palpal segment.

03E11B403676FFF8FCDAFBFCFDA1FB84.taxon	discussion	DISCUSSION Following the keys to Nearctic genera of Gagné (1981), Neurolyga magnifica n. sp. falls in the Micromyini subgroup of genera Campylomyza Meigen, 1818, Neurolyga Rondani, 1840 (under the name Cordylomyia Felt, 1911 as junior synonym, see Jaschhof 1997), and Corinthomyia Felt, 1907 (all in Campylomyzini), because of its CuA forked, M 3 + 4 very faint, appearing as a fold distally vanishing, R 5 as long as wing, tibiae without disto-ventral spines, C extending well beyond R 5 for half distance between R 5 and M 1 + 2, along wing margin, R 1 more than three times length of Rs, empodia broad. The new taxon has the following synapomorphies of the clade Micromyini, as outlined by Jaschhof (1998: fig. 236): anal area weakly convex, veins h, sc-r, CuP, and A absent, M 1 + 2 simple, M 3 + 4 reduced to a fold between M 1 + 2 and CuA, density of macrotrichia reduced on wing membrane. Following the key to European genera of Skuhravá (1997), N. magnifica n. sp. falls in the Campylomyzini because of the following characters: ocelli three, M 1 + 2 simple, R 5 as long as wing, few macrotrichia on wing membrane, eye bridge narrowed laterally, forming medially the apparent third eye, empodia well developed and very setose. Furthermore, N. magnifica n. sp. has not the synapomorphies of the Acoenoniini, sister group of Campylomizini, viz. tibia with distal rigid and sharp setae, shortening of R 5 and of distal part of C, “ Sinnesporen ” few (Meyer & Spungis 1994; Jaschhof 1998). Following the key to Campylomizini genera of Skuhravá (1997), N. magnifica n. sp. would fall near the genus Corinthomyia because of the following characters: female flagellomeres without distal sensory collar (the presence of a sensory collar is a synapomorphy of the group of genera Excrescentia + Micropteromyia + Campylomyza); macropterous; cubital fork forming almost a right angle, more acute in Neurolyga (Edwards 1938 c). This character is probably subject to variation and of little value. Other differences between Neurolyga and Corinthomyia concern male structures and female spermathecae, not available in our fossil (Jaschhof 1998). More precisely, N. magnifica n. sp. differs from Micropteromyia Mamaev, 1960 in its antennae 14 - instead of 12 - segmented and palpus 4 - segmented (Mamaev 1960, 1963; Jaschhof 1998). The female of Excrescentia Mamaev & Berest, 1991 has 14 - segmented antennae, but most of them with a well developed collar-shaped sensoria, unlike in N. magnifica n. sp. (Mamaev & Berest 1991; Økland 1995). The female Campylomyza have also a collar-shaped sensoria. Among the non Holarctic faunas, the Neotropical genus Psadaria Enderlein, 1940 has a female identical to those of Corinthomyia brevicornis, after Freeman (1953). Gagné (1994) indicated that it could be a junior synonym of this last genus but after the revision of Lagrange (1980: fig. 2), the wing venation of Psadaria pallida Enderlein, 1940 strongly differs from that of C. brevicornis and of N. magnifica n. sp. in its reduced vein M 1 + 2, and veins R 1, R 5 and CuA not reaching wing margin. Other known Neotropical taxa correspond to genera recorded from the Holarctic. Kieffer (1919) described the genus African Tricampylomyza (Cameroun) in the tribe “ Campylomyzariae ”. It has antennae with eight flagellomeres and a one-segmented palp. The Asiatic and Australian faunas are very incompletely known with species belonging to Holarctic genera. The type female of N. magnifica n. sp. differs from the female of the recent unique species Corinthomyia brevicornis (Felt, 1907) in the following characters: 14 antennomeres instead of 11; presence of numerous long setae on flagellomeres disposed in three rows, instead of only a “ subapical band of very numerous short sensory spines and some a little longer ” (Edwards 1938 c: 203, fig. 13 b). Thus, we can exclude the genus Corinthomyia. We tentatively attribute this fossil to the genus Neurolyga, but only the discovery of the male will allow to precise its exact position. One “ spectacular ” character of N. magnifica n. sp. is its composed eyes completely divided into two lateral eyes and one dorsal eye, unlike Corinthomyia, in which the eyes are 2 - 3 facets wide at narrowest point (Edwards 1938 b). The eyes are completely divided into three parts in Campylomyza (Edwards 1938 c) and Tricampylomyza (Kieffer 1919). The situation is variable (divided or not) in the different Neurolyga species (Edwards 1938 c), and the eyes are not divided in Excrescentia (after Mamaev & Berest 1991). Thus, this character alone is not sufficient to correctly separate the new species N. magnifica n. sp. from other Campylomizini. Gagné (1977) described the Cretaceous genus and species Cretocordylomyia quadriseries from the Cedar Lake amber (Canada). He considered that it is “ close to Cordylomyia and Campylomyza ” on the basis of the “ long, broad empodium and long R 1 ”. Gagné indicated that the female flagellomeres of Cretocordylomyia are “ similar to those of Cordylomyia spp. ” but, after his figure 7, they bear a row of long basal setae, absent in recent Neurolyga (see Edwards 1938 c: figs 11, 12). Nevertheless, Cretocordylomyia differs from N. magnifica n. sp. in the presence of only one row of long setae on female flagellomeres, its fork of CuA forming an acute angle, and its vein M 1 + 2 vanishing in wing membrane and not ending on posterior wing margin. It is nearly impossible at this stage to be precise about the phylogenetic affinities of Cretocordylomyia within the Campylomyzini because of the following problems: the Neotropical and African genera were not introduced in the analysis of Jaschhof; our knowledge is still very incomplete, as the Asiatic and Australasian fauna are poorly known, with probably new taxa to discover. Nevertheless, the presence of fossil representatives of this clade in the Late Cretaceous and Early Tertiary demonstrates its great antiquity.	en	Nel, André, Prokop, Jakub (2006): New fossil gall midges from the earliest Eocene French amber (Insecta, Diptera, Cecidomyiidae).

03E11B40367CFFFDFCCCFC03FC22FEFC.taxon	discussion	DISCUSSION After Wood & Borkent (1986, 1989), Electroxylomyia eocenica n. gen., n. sp. falls in the Cecidomyiidae rather than in Sciaridae, because of the following synapomorphies: presence of an eye bridge (character also present in Sciaridae and Scatopsoidea), tibial spurs absent (see also Gagné 1994) (but character also present in Scatopsidae); setae of flagellomeres arranged in encircling whorls. After the partial phylogenetic analysis of the cecidomyiid subfamilies of Jaschhof (2000), Electroxylomyia n. gen. has the two synapomorphies of the Porricondylinae + Cecidomyiinae, viz. the lack of ocelli and first tarsomeres shortened. Following the key to dipteran families of McAlpine (1981), Electroxylomyia n. gen. falls in the Porricondylinae because of the following characters: vein A 2 absent, R with only two branches, C continuing around wing, ocelli absent, tarsomere 1 much shorter than 2, M 1 + 2 absent, R 5 as strong as other veins, female cercus two-segmented. Following the keys to Nearctic and European genera proposed by Gagné (1981, 1994) and Skuhravá (1997), Electroxylomyia n. gen. shares with the Heteropezini its wing veins greatly reduced and CuA simple. But similarly reduced wing can be found in some Winnertziini (Mamaev & Zaitzev 1998). Also, both the male and female of Electroxylomyia n. gen. have eleven flagellomeres, instead of 10 or less as in recent Heteropezini. This last character would exclude affinities with this last tribe. Within the Porricondylinae with more than 10 flagellomeres, Electroxylomyia n. gen. would fall in the Winnertziini because it has only 11 flagellomeres, and no circumfila on its flagellomeres. Thus, we tentatively attribute it to this tribe rather than to the Heteropezini. Nevertheless, a phylogenetic analysis of the whole subfamily Porricondylinae is necessary before any definite conclusion. Electroxylomyia n. gen. could as well have been a Heteropezini with 11 flagellomeres. After the key to genera of Winnertziini of Mamaev & Zaitzev (1998), Electroxylomyia n. gen. could fall in Kronomyia Felt, 1911 because of the following characters: fifth tarsal segment only slightly longer as fourth, without sensorial bristles on the ventral surface; no band-shaped or digitate, horseshoe-shaped sensorium on flagellomeres; antennae of male with 2 + 11 segments, as in female. But Electroxylomyia n. gen. strongly differs from Kronomyia in its vein M absent and its palpus very strongly reduced, not visible, absent or with only one segment (Parnell 1971; Skuhravá 1997). Electroxylomyia n. gen. differs from Rhipidoxylomyia Mamaev, 1964 in its median veins absents and in the absence of star-like or fan-like sensorium on flagellomeres (Mamaev 1964). It differs from Clinorrhytis Kieffer, 1896 in its male antennae 11 - segmented and its vein M absent (Kieffer 1913). It also differs from Sylvenomyia Mamaev & Zaitzev, 1998 in its male antennae 11 - segmented. It differs from Winnertzia Rondani, 1861 and Parwinnertzia Felt, 1919 in the absence of digitate, horseshoe-shaped sensorium on flagellomeres. Electroxylomyia n. gen. shares with Cryptoxylomyia Mamaev & Zaitzev, 1998 the reduction of the mouth parts and that of wing venation, but it has no trace of forked or digitate sensorium on flagellomeres, unlike this last genus.	en	Nel, André, Prokop, Jakub (2006): New fossil gall midges from the earliest Eocene French amber (Insecta, Diptera, Cecidomyiidae).
