Pronotum 1.6–1.8 × wider than long; disc shining, with dense, coarse punctures, slightly convex; lateral margins rounded; apical margins slightly concave; basal margin medially convex. Elytra 1.2–1.3 × longer than wide; disc with coarse punctures arranged into paired longitudinal lines, with fine punctures between coarse punctures; lateral margins rounded, widest at basal 1 / 4; humeral calli well developed, hind wings normal (Fig. 4 A). Tarsomeres I of front and middle legs slightly swollen and asymmetrical in males (Fig. 3 G); normal in females (Fig. 3 H).

(2017) presented results of a project on species diversity of leaf beetles at the Xitou Nature Education Area (溪頭教育園區) in Central Taiwan. They collected leaf beetles by sweeping one day every month from November 2014 to June 2016. Euphitrea flavicornis was one of the dominant species, with 781 adults represented in collections during the study. Adults were present during all years, although few were collected during winter. Similar results were documented in populations collected using Malaise traps set at Tahanshan (大漢山), South Taiwan (see “ Additional material examined ”).</p><p>Distribution.</p><p>Central and south Taiwan (Fig. 5). Whether populations of this species can survive at Mt. Alishan, more than 2000 m elevation, is unknown. Specimens collected from Mt. Alishan are more than 100 years old. The word “ Arisan (= Alishan) ” during the past may refer to a much wider range than at present, indicating the whole township. Thus, these old specimens may not have been collected at high altitudes.</p></div>	https://treatment.plazi.org/id/96E2102FA40F5845AF47BC665B47C7D8	Public Domain	No known copyright restrictions apply.

Head, prothorax, and legs yellowish or reddish brown (Fig. 10 A – C); meso- and metathoracic, and abdominal ventrites blackish brown; antennomeres I – IV yellowish brown, apical 1 / 2 of V dark brown, VI – XI black. Furrows lateral to vertex deep and long, apically extending beyond apical margins of eyes (Fig. 2 E). Antennae (Fig. 11 A) filiform in males, ratios of lengths of antennomeres I – XI 1.0: 0.5: 0.4: 0.5: 0.6: 0.6: 0.6: 0.6: 0.6: 0.6: 0.8; ratios of length to width from antennomeres I – XI 2.9: 1.9: 2.0: 2.3: 2.5: 2.5: 2.5: 2.6: 2.6: 2.7: 3.9; much smaller in females, ratios of lengths of antennomeres I – XI (Fig. 11 B) 1.0: 0.5: 0.5: 0.5: 0.6: 0.6: 0.6: 0.6: 0.6: 0.6: 0.9; ratios of length to width from antennomeres I – XI 3.6: 2.3: 2.8: 2.6: 3.0: 2.4: 2.5: 2.4: 2.5: 2.5: 3.7. Pronotum 1.7 × wider than long; disc shining, with sparse, fine punctures, moderately convex; lateral margins rounded; apical margins almost straight; basal margin slightly and medially convex. Elytra 1.3 × longer than wide; disc with coarse punctures arranged longitudinally, with fine punctures between longitudinally arranged coarse punctures; lateral margins rounded, apically narrowed behind basal 1 / 3; humeral calli well developed, hind wings normal. Tarsomeres I of front and middle legs strongly swollen in males (Fig. 11 H); less swollen and much smaller in females (Fig. 11 I). Apical margin of abdominal ventrite V in males trilobed, notches shallow; apical margin of abdominal ventrite V broadly rounded in females. Aedeagus (Fig. 11 C – E) slender, ~ 4.7 × longer than wide; parallel-sided, apex widely rounded, slightly convex at middle of apical margin; moderately curved in lateral view; ventral surface with wide, longitudinal, sclerotized areas from apical 1 / 12 to middle, sides surrounded by membranous areas; tectum slightly sclerotized. Endophallic spiculae reduced. Gonocoxae (Fig. 11 F) longitudinal and connected at base; each gonocoxa apically narrow; apex narrowly rounded or truncate; curved inwards; with eight long apical setae. Ventrite VIII (Fig. 11 G) well sclerotized and small, short, and dense setae arranged into transverse line along apical margin, apical margin rounded, with four long setae at sides, spiculum extremely long. Spermathecal receptaculum (Fig. 11 I) strongly swollen; pump long and curved; sclerotized spermathecal duct short beyond spermathecal gland, base of spermathecal gland enlarged and sclerotized.</p><p>Diagnosis.</p><p>Adults of Euphitrea nisotroides are similar to those of E. taiwana with similar color patterns, but E. nisotroides can be easily recognized by its distinct, elongate longitudinal ridge on the vertex of the head (Fig. 2 E) (short longitudinal ridges on the vertex in E. taiwana; Fig. 2 F). In addition, the antennae and tarsi are sexually dimorphic (Fig. 11 A, B, H, I), the aedeagi are slenderer (Fig. 11 C, D) (4.7 × longer than wide), and the apical margin of the abdominal ventrite VIII in females is rounded (Fig. 11 G). These characters differ in E. taiwana, with similar sizes of antennae (Fig. 14 A, B) and tarsi (Fig. 14 H, I) in both sexes, wider aedeagi (Fig. C, D) (3.8 × longer than wide) and truncate apical margin of abdominal ventrite VIII in females (Fig. 14 G).</p><p>Food plants.</p><p>Cannabaceae: Celtis sinensis Pers.; Ulmaceae: Zelkova serrata (Thunb.) Makino; Urticaceae: Boehmeria nivea (L.) Gaudich. (Fig. 12 A); Debregeasia orientalis C. J. Chen.</p><p>Distribution.</p><p>China, Japan, and Taiwan. Only one specimen was collected from the North Borodino Island, Japan (Chûjô 1958). No detailed studies was conducted on Chinese specimens. Records from China and Japan need further confirmation. The species is widespread in the lowlands of central and south Taiwan. Adults were not found higher than 2000 m elevation (Fig. 13).</p></div>	https://treatment.plazi.org/id/D15F77425E37549DAB1CD88E52AD497C	Public Domain	No known copyright restrictions apply.

Head, prothorax, and legs yellowish or reddish brown (Fig. 10 D – F); meso- and metathoracic, and abdominal ventrites blackish brown; antennomeres I – IV yellowish brown, apical 1 / 2 of V dark brown, VI – XI black. Furrows lateral to vertex shallow and short, apically reaching or slightly exceeding apical margins of eyes (Fig. 2 F). Antennae (Fig. 14 A) filiform in males, ratios of lengths of antennomeres I – XI 1.0: 0.5: 0.5: 0.5: 0.6: 0.6: 0.7: 0.7: 0.7: 0.7: 0.8; ratios of length to width from antennomeres I – XI 3.1: 2.0: 2.2: 2.4: 2.7: 2.3: 2.5: 2.5: 2.2: 2.4: 3.1; similar in females, ratios of lengths of antennomeres I – XI (Fig. 14 B) 1.0: 0.5: 0.5: 0.6: 0.6: 0.6: 0.6: 0.6: 0.6: 0.6: 0.8; ratios of length to width from antennomeres I – XI 2.6: 2.1: 2.5: 2.8: 2.5: 2.3: 2.3: 2.3: 2.4: 2.2: 3.1. Pronotum 1.7 × wider than long; disc shining, with sparse, fine punctures, moderately convex; lateral margins rounded; apical margins almost straight; basal margin slightly and medially convex. Elytra 1.3 × longer than wide; disc with coarse punctures arranged longitudinally, with fine punctures between longitudinally arranged coarse punctures; lateral margins rounded, apically narrowed behind basal 1 / 3; humeral calli well developed, hind wings normal. Tarsomeres I of front and middle legs strongly swollen in males (Fig. 14 H); less swollen in females (Fig. 14 I). Apical margin of abdominal ventrite V in males trilobed, notches shallow; apical margin of abdominal ventrite V broadly rounded in females. Aedeagus (Fig. 14 C – E) wide, ~ 3.8 × longer than wide; parallel-sided, apex widely rounded, slightly convex at middle of apical margin; moderately curved in lateral view; ventral surface with wide, longitudinal, sclerotized areas from apical 1 / 6 to middle, sides surrounding with membranous areas; tectum membranous. Endophallic spiculae reduced. Gonocoxae (Fig. 14 F) longitudinal and connected at base; each gonocoxa apically narrow; apex narrowly rounded or truncate; curved inwards; with eight long apical setae. Ventrite VIII (Fig. 14 G) well sclerotized and small, short, and less dense setae arranged into transverse line along apical margin, apical margin truncate, with two or three long setae at sides, spiculum extremely long. Spermathecal receptaculum (Fig. 14 J) strongly swollen; pump long and curved; sclerotized spermathecal duct short beyond spermathecal gland, base of spermathecal gland enlarged and sclerotized.</p><p>Color variation.</p><p>Most individuals collected from Ilan county have dark reddish brown heads and prothoraces and yellowish brown antennae and legs (Fig. 10 G – I), which look like members of E. flavicornis species group.</p><p>Diagnosis.</p><p>Adults of Euphitrea taiwana are similar to those of E. nisotroides with similar color patterns, but E. taiwana can be easily recognized by the shorter longitudinal ridges on the vertex of the head (Fig. 2 F) (long longitudinal ridges on vertex in E. nisotroides (Fig. 2 E)). In addition, similar sizes of antenna (Fig. 14 A, B) and tarsi (Fig. 14 H, I) are present in both sexes, the aedeagi are comparatively wider (Fig. 14 C, D) (3.8 × longer than wide) and the apical margin of abdominal ventrite VIII is truncate in females (Fig. 14 G). These characters differ from those of E. nisotroides, which possess sexually dimorphic antennae (Fig. 11 A, B) and tarsi (Fig. 11 H, I) in both sexes, more slender aedeagi (Fig. 11 C, D) (4.7 × longer than wide) and rounded apical margin of abdominal ventrite VIII in females (Fig. 11 G).</p><p>Food plants.</p><p>Asteraceae: Petasites formosanus Kitam. (Fig. 12 B); Cannabaceae: Celtis formosana Hayata (Fig. 12 E); Lythraceae: Lagerstroemia subcostata Koehne; Moraceae: Broussonetia monoica Hance (Fig. 12 D); Rosaceae: Prunus campanulata Maxim.; Ulmaceae: Ulmus uyematsui Hayata (Fig. 12 C); Urticaceae: Debregeasia orientalis C. J. Chen (Fig. 12 F); Gonostegia hirta (Blume) Miq.; Oreocnide pedunculata (Shirai) Masam.</p><p>Distribution.</p><p>This species is extremely common in Taiwan, including a small island, Keelungyu Island (基隆嶼), near northern Taiwan (Fig. 13). They are rather dominant in northern Taiwan. Some populations occur higher than 2000 m elevations.</p></div>	https://treatment.plazi.org/id/6190F00167EB5102BA9B566AF19540AF	Public Domain	No known copyright restrictions apply.

General color blackish brown or dark reddish brown (Fig. 7 D – F); antennae, legs, and mouthparts yellow but antennae more or less darkened; elytra dark metallic blue. Frontal ridge flat. Furrows lateral to vertex shallow and short, apically reaching or slightly exceeding apical margins of eyes (Fig. 2 D). Antennae (Fig. 9 A) filiform in males, ratios of lengths of antennomeres I – XI 1.0: 0.5: 0.5: 0.4: 0.6: 0.6: 0.7: 0.7: 0.7: 0.6: 0.8; ratios of length to width from antennomeres I – XI 3.3: 2.1: 2.3: 2.5: 2.7: 2.9: 3.0: 2.8: 2.6: 2.4: 3.0; similar in females, ratios of lengths of antennomeres I – XI (Fig. 9 B) 1.0: 0.6: 0.5: 0.6: 0.6: 0.6: 0.7: 0.7: 0.7: 0.6: 0.9; ratios of length to width from antennomeres I – XI 2.9: 2.4: 2.7: 2.6: 3.1: 2.8: 2.8: 2.6: 2.6: 2.4: 3.0. Pronotum 1.8–1.9 × wider than long; disc shining, with dense, coarse punctures, convex; lateral margins rounded; apical margins concave; basal margin medially convex. Elytra 1.1 × longer than wide; disc with coarse punctures arranged into paired longitudinal lines, with fine punctures between coarse punctures; lateral margins strongly rounded, widest at basal 1 / 4; humeral calli well developed, hind wings normal. Tarsomeres I of front and middle legs slightly swollen and asymmetrical in males (Fig. 9 G); normal in females (Fig. 9 H). Apical margin of abdominal ventrite V in males trilobed, notches shallow; apical margin of abdominal ventrite V broadly rounded in females. Aedeagus (Fig. 9 C, D) wide, ~ 4.0 × longer than wide; parallel-sided, moderately apically narrowed at apical 1 / 7, apex narrowly rounded; slightly curved in lateral view; tectum membranous. Endophallic spiculae reduced. Gonocoxae (Fig. 9 E) longitudinal and connected at base; gonocoxa approximate, apically narrow; apex narrowly rounded or truncate; with eight long apical setae. Ventrite VIII (Fig. 9 F) well sclerotized and small, several short setae arranged into transverse line along apical margin, apical margin rounded, with three long setae at sides, spiculum extremely long. Spermathecal receptaculum (Fig. 9 I) slightly swollen; pump wide and curved; sclerotized spermathecal duct short beyond spermathecal gland, base of spermathecal gland enlarged and sclerotized.</p><p>Diagnosis.</p><p>Adults of Euphitrea tsoui sp. nov. are characterized by their transversely oval bodies with elytra 1.1 × longer than wide (oval bodies with elytra&gt; 1.1 × longer than wide in others). In addition, some genital characters are diagnostic including wider aedeagi (Fig. 9 C) (slenderer aedeagi in E. flavicornis (Fig. 3 C) and E. jungchani sp. nov. (Fig. 8 C)) and slightly swollen spermathecal receptaculum (Fig. 9 I) (swollen spermathecal receptaculum in E. flavicornis (Fig. 3 C) and E. houjayi sp. nov. (Fig. 6 C)).</p><p>Food plants.</p><p>Urticaceae: Debregeasia orientalis C. J.
