038987D6FFAA6E3DFF2BFF35E1B1FAE2.taxon	diagnosis	Diagnosis. Eurystylus is distinguished from other genera of the tribe Mirini by the following characters (whereas some of these characters are shared with the assumed related taxa, Eocalocoris Miyamoto & Yasunaga [EC], Eurystylopsis Poppius [EP], Heteropantilius Zheng & Liu [HP] or Miyamotoa Yasunaga [MY]): Body remarkably thick, box like [HP, EC, EP], generally matte or shagreened [EP]; dorsum impunctate [HP, EC, MY], with at least two types of vestiture [EP]; head weakly porrect and relatively horizontal or prognathous [HP, EC, EP, MY]; lateral margin of frons, bordering to antennal tubercle and inner margin of eye, with a fuscous, velvety mark that is usually visible even in species with darkened head (Figs. 1 H, 2 E, F); antenna, shorter than body, with segment I tumid, obviously flattened, segment II clavate (its apical part more than twice as thick as base), and segments III and IV short and filiform [HP, EC, EP, MY]; pronotum often with a pair of dark spots on disk, sometimes forming eyeshape, so-called ‘ head bugs’ (as in Figs. 2 A, E; 3 E); collar thickened, broader than base of antennal segment II; scutellum tumid, long, with its lateral margin length greater than basal width; each femur more or less flattened [EP]; metatibia not much longer than metafemur; male genital segment (pygophore) noticeably shortened; abdominal sterna VIII and IX in female narrow; left paramere usually strongly constricted at base of widened and flattened (often flap-like) hypophysis (Fig. 4); endosoma with well-developed membranous lobes [EC, MY], with one to four lobal sclerites (Fig. 5, FL, ML, PL, TL); seminal duct strongly constricted distally (Fig. 5 C); secondary gonopore thick-rimmed, with triangular or heart-shaped aperture [EC, HP, MY]; and female bursa copulatrix with a confluent ventral labiate plate [EC, EP]. The final-instar nymph is unique in having the generally pale, ovoid, thick body with several pairs of eye-like, or ocellate spots on dorsum (Fig. 2 B – D).	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

038987D6FFAA6E3DFF2BFF35E1B1FAE2.taxon	biology_ecology	Biology. As evidenced by many Eurystylus species that are collected on inflorescences, floral nectar and pollen are considered to be their major diets (Yasunaga, 2001). Most congeners are presumed to be herbivorous and polyphagous. The immature forms of more than seven species (including some undetermined or undescribed ones from tropical Asia) were confirmed to inhabit inflorescences of various dicots (see Table 1). The adults of the species shown in Table 1 (except for E. jingfui) were observed to suck on flower buds, petals and / or pedicels (cf. Fig. 1 G). In the Afrotropical Region, Eurystylus oldi Poppius is frequently documented as a major pest of sorghums, Sorghum bicolor (L.) Moench (Poaceae) in particular, and some Eurystylus species in South Africa were documented to feed on both male and female flowers of a castor, Ricinus communis L. (Euphorbiaceae), causing them to shrivel and die; in some cases, entire stems die (Wheeler, 2001). In Asia, no Eurystylus member has ever been reported as an agricultural pest, even though some species actually inhabit inflorescences of economic fruit trees, and ornamental or medicinal plants (e. g., chestnuts, oranges, mangos, aralias, lilacs; Table 1). The population densities of Asian species are usually not significant, and any harmful gregarious feeding is currently not recognized. One generation per year is assumed for Eurystylus species inhabiting temperate and colder climate zones, whereas those in tropics, subtropics or warm temperate zone appear to have a bivoltine or multivoltine life cycle.	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

038987D6FFAA6E3DFF2BFF35E1B1FAE2.taxon	discussion	Discussion. Eurystylus is easily separable from related genera by the flattened antennal segment I, a pair of fuscous, velvety spots at lateral corner on the frons, thicker collar, elongate scutellum, and shortened genital segments (male pygophore and female segments VIII and IX). These characters will distinguish Eurystylus from taxa possessing similar facies (e. g., tumid box-like body, clavate antennal segment II), such as Eurystylopsis known from Nepal, Taiwan and continental China, Eocalocoris from southwestern Japan, Heteropantilius from China and Taiwan, and Miyamotoa originally described from the Amami Island-Group of the Ryukyus. However, these genera equally have more smooth dorsum, cylindrical antennal segment I, nearly equilateral scutellum, and conventional mirine paramere shape, in addition to their own unique characters or autapomorphy (for further information, see Yasunaga, 1990, 1995; Yasunaga & Takai, 1994; Zheng et al., 2004). The below key equivocally distinguishes the five related genera. Within the four genera mentioned in above generic diagnosis, Eurystylopsis is assumed to be most closely related to Eurystylus, because these two genera share seven diagnostic characters, as well as the largely matte dorsal surface, and similar coloration, vestiture pattern (Fig. 9 A – B), and shape of the metathoracic scent efferent system (Fig. 8 G – H). The phylogenetic relationship of Eurystylus to other mirine genera will need to be further elucidated. However the shared characters of above-mentioned genera imply that at least the four genera may be originated from a same lineage; Miyamotoa is separated from the other genera in having the reduced M-vein that represents unusual character state in the tribe Mirini. On the other hand, a few more superficially similar taxa appear to exist in the Old World. For instance in the Australian Region, the poorly known Pseudeurystylus clavicornis Poppius, 1915 (Fig. 9 F), the sole representative of the monotypic genus Pseudeurystylus Poppius, 1915, also shares similar color and vestiture patterns, clavate second antennal segment, tumid body and pronotum, and thick pronotal collar. However, Pseudeurystylus can be distinguished easily from all above mentioned taxa by the four ivory-white, callose stripes on the pronotal lateral margin and propleuron, the pronotal collar thicker than the base of antennal segment II at middle but not laterally (the collar has the almost similar thickness throughout in Eurystylus) and the pronotal callosities developed and nearly contiguous to the collar. In the Ethiopian Region where more than twelve Eurystylus species occur, Stonedahl (1995) considered the possible relationship between Eurystylus and Volumnus Stål, 1866 (including Yambio Linnavuori, 1975), mainly based on dorsal pilosity, thick and relatively short antennal segments III and IV and the presence of “ a small, plate-like process on the base of maxillary plates, ventral to antennal fossae ” (Stonedahl, 1995). However, as pointed out by Stonedahl for the vestiture (op. cit.), these character states are not considered unique, being observed in other mirine genera; the genital structures of Volumnus are also different from those of Eurystylus. A relationship between Eurystylus and Volumnus appears only superficial. To demonstrate a satisfactory phylogenetic position and sister taxa of Eurystylus, comprehensive work treating all the Old World members is required. In Japan and Taiwan, three species, Eurystylus coelestialium, E. luteus, and E. sauteri, have been reported. However, our attempts to identify the specimens from these areas revealed that the Japanese and Taiwanese populations which have been assigned to E. luteus should belong to E. sauteri, and all previous records of E. sauteri from SW Japan and Taiwan were incorrect (see below Discussion for E. ryukyus and E. sauteri). Judging from the overall similarities (as in Figs. 3 A – G, 4 B – I) and distribution patterns (Fig. 7), it is highly probable that luteus (described by Hsiao from Anhui, China in 1941) and sauteri (by Poppius from Taiwan in 1915) are conspecific. The holotype of luteus is unfortunately female, but the male endosomal illustrations based on Chinese materials (Zheng & Chen, 1991; Zheng et al., 2004) doubtlessly coincide with those found in Japan and Taiwan (Fig. 4 D – I). We therefore refrain from using luteus for relevant Japanese and Taiwanese specimens, to avoid further taxonomic confusion.	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

The first author collected an undetermined (possibly undescribed) species very similar to E. jingfui from Indonesia (Sumatra), Peninsular Malaysia and Thailand; however, this SE Asian species is distinct in having the conspicuous, white striae on the lateral side of the body (thoracic pleura and proximal abdominal sterna). On the other hand, a male collected from subtropical plain in Nepal (Fig. 1 A) is most probably conspecific with E. jingfui. Because this specimen is unfortunately teneral and the male genitalia were invisible, we refrain from including its definitive record in the present work.	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

Most individuals of this new species were collected from various inflorescences and four plant species were confirmed as the breeding hosts (Table 1). The adults are sometimes attracted to light traps. Collecting records suggest E. ryukyus has a multivoltine life cycle.	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

038987D6FFA56E37FF2BFE84E45BF80E.taxon	discussion	Discussion. This new species has been regarded as E. sauteri since Miyamoto & Yasunaga (1989) listed an earlier record from Ishigaki Island of the Ryukyus, although we now can no longer trace the source. Previously, a species (x) restricted to southern Japan and Taiwan with the entirely darkened antennal segment III and apically toothed endosomal PL was identified as E. sauteri, and its close relative (y), occurring in Honshu, Shikoku and Kyushu, with the bicolored antennal segment III and wholly toothed PL was E. luteus (Yasunaga, 2001). Both species are also clearly separated each other by the male genitalia as well as shape of the final-instar immatures (Fig. 2 B vs. 2 C). It was not until we could access images of the holotype of E. sauteri quite recently that we were aware of this misidentification; base of the antennal segment III of the holotype is pale (Fig. 8 C). Because the species (x) is distributed in both Japan and Taiwan (type locality of sauteri), no one has doubted of its wrong identity for long time. On the other hand, the other species (y) was confirmed as true E. sauteri. Accordingly, E. luteus is now suspected to be conspecific with E. sauteri, based on our examinations of the morphological characters including the genitalia and distribution patterns (Fig. 7). To verify the definitive identity for E. luteus, additional information on the female genitalic structures and final-instar immature form of Chinese materials is required.	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

038987D6FFBE6E2AFF2BF91CE549FDA6.taxon	discussion	Discussion. Kawasawa & Kawamura (1975) first reported E. sauteri from Japan (Shikoku and Kyushu). Subsequently, Miyamoto & Yasunaga (1989) considered E. sauteri was restricted to Ryukyus and Taiwan [species (x) in Discussion of E. ryukyus above], and Yasunaga et al. (1999) assigned the species occurring in Honshu, Shikoku and Kyushu [species (y)] to E. luteus Hsiao. As mentioned above, there is a strong likelihood that E. luteus and E. sauteri are conspecific, based on available evidence. We recognize the appropriate treatment of Kawasawa & Kawamura (1975), using the name sauteri for the species (y). Within the Ryukyus, E. sauteri is yet to be confirmed but E. ryukyus is abundant. These two species coexist in Taiwan and southernmost parts of Kyushu and Shikoku (Fig. 7). We currently cannot elucidate why E. sauteri does not inhabit the subtropical islands. Incidentally, three female specimens from Shan District of N. Myanmar (TYCN) most probably represent E. sauteri, which is now assumed to widespread over eastern Asia.	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

038987D6FFBC6E2BFF2BF9D1E250FC52.taxon	discussion	Discussion. This genus is considered to be the most closely related taxon to Eurystylus. Two species were found to be associated with inflorescences of chestnut, Castanea sp. and orange, Citrus sp. (Eurystylopsis clavicornis) and an undetermined broadleaf (Ep. hermandi, Fig. 9 C – D) in Nepal. These observations may imply a relationship between Eurystylus and Eurystylopsis. Poppius (1915) described a new genus Eurystylomorpha to accommodate a single species, Em. crassicornis (Fig. 8 D) from Taiwan, comparing it with Eurystylus only. We find it mysterious that he (loc. cit.) did not mention his own genus Eurystylopsis proposed for two Himalayan species just four years prior (Poppius, 1911). We imagine that Poppius did not included Eurystylopsis because the geographical distribution of the genera in India and Taiwan are remotely disjunct. However, four additional species were subsequently described from continental China (Zheng & Chen, 1991; Zheng et al., 2004). We have also found E. clavicornis distributed in Nepal and Thailand, which could connect the distribution range for the genus. Both nominal genera share numerous character states, except for the carina on vertex (absent in Eurystylopsis; thin but complete in Eurystylomorpha), the overlapping of mesoscutum, and the coloration of dorsal pilosity. These minor differences are now considered insufficient to recognize them as two independent genera. We therefore suggest a new subjective synonymy, Eurystylopsis Poppius, 1911 = Eurystylomorpha Poppius, 1915. Accordingly, Eurystylopsis is now known widely from the Oriental to eastern Palearctic regions.	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

Recognized by its rather conventional mirine shape, generally dark, largely matte, elongate ovoid body; simple, reclining setae and silvery or partly golden pubescence on dorsum; basally constricted interramal lobe with narrowly sclerotized edge; and Y-shaped dorsal structure. This species (male and reddish female) is at first sight similar to E. clavicornis (Figs. 8 H – I, 9 A – B), from which E. crassicornis can be distinguished by the larger size, long antennal segment II longer than the metatibia, and thick-rimmed, squared sclerotized ring.	en	Yasunaga, Tomohide, Nakatani, Yukinobu, Chérot, Frédéric (2017): Review of the mirine plant bug genus Eurystylus Stål from Japan and Taiwan (Hemiptera: Heteroptera: Miridae: Mirinae), with descriptions of two new species, a new synonymy and a new combination.

038987D6FFBD6E2EFF2BFBF0E31AFF4E.taxon	description	Description. Female: Similar to male, but dorsum sometimes partly or largely mottled with reddish patterns. Body generally dark brown, elongate ovoid; dorsal surface weakly shining, partly or largely tinged with red, with two types of vestiture: uniformly distributed, simple, short, brownish, reclining setae and densely distributed, silvery (party golden), reclining or semierect setae (Fig. 10 C). Antenna dark brown; basal half of segment II reddish brown; bases of segments III and IV yellowish brown. Labium shiny chocolate brown, not exceeding apex of mesocoxa. Pronotum uniformly darkened, with narrowly pale basal margin (but in some specimens pronotum and scutellum largely reddish brown with fuscous stripes as in Fig. 9 B); scutellum with reddish apex, moderately tumid; pleura dark brown, with grayish yellow scent efferent system (Fig. 8 F). Hemelytron uniformly dark brown, more or less tinged with red; median part of cuneus yellow; membrane smoky brown, with semitransparent, irregular maculae at middle. Coxae and legs dark brown; each trochanter pale brown; apical half parts of pro- and mesotibiae (except for dark apices) and median part of metatibia pale reddish or yellowish brown. Abdomen dark brown. Female genitalia (Fig. 10 D – E): Genital chamber with distinct sclerotized perimeter surrounding lateral oviducts; sclerotized rings developed, rather squared (Fig. 10 D); interramal lobes somewhat constricted basally, with narrowly sclerotized lateral margin (Fig. 10 E). Measurements. ♀: Total body length 5.8 ̄ 6.3; width of head across eyes 1.04 ̄ 1.09; width of vertex 0.43 ̄ 0.48; lengths of antennal segments I ̄ IV 0.95 ̄ 0.97, 2.66 ̄ 2.85, 0.95 ̄ 1.11, 0.58 ̄ 0.67; length of labium 1.99 ̄ 2.04; mesal length of pronotum including collar 1.23 ̄ 1.26; basal width of pronotum 1.99 ̄ 2.09; maximum width across hemelytron 2.28 ̄ 2.40; and length of metafemur, tibia and tarsus 2.47 ̄ 2.57, 3.41 ̄ 3.43, 0.64 ̄ 0.67. According to Poppius (1915), body length 6.2 and maximum width 2.2 in holotype male. Biology.
