( Figures 46–65 ) Male. Length: 11.0 mm; humeral width: 3.0 mm. Body glossy and dark reddish brown. Mandible reddish brown at basal half and darker towards apex ( Fig. 50 ). Basal half of antennomeres III–IV pale yellow and moderately covered with dense short white pubescence, basal half of antennomeres V–XI pale brown and moderately covered with dense short brown pubescence, apical half of antennomeres III–XI dark brown and moderately covered with dense short brown pubescence, antennomeres III–X sparsely with longer black hairs apically ( Figs 46 & 47 ). Pronotum covered with 3 vague and longitudinal yellowish brown stripes, one narrow in middle, and the other two broad at sides ( Fig. 46 ). Scutellum densely covered with yellowish brown pubescence ( Fig. 46 ). Elytra moderately covered with dense and short brown hairs, elytron covered with fragmentary white spots behind the depression forming a vague and oblique band, sparsely with a series of fragmentary white spots from posterior of the band and along suture to elytral apex, with a triangular yellowish brown to white spot behind middle, with an inverted “V” white spot near apex ( Fig. 46 ); marginal angles black ( Fig. 51 ), sparsely covered with short white pubescence basally and long black hairs ( Fig. 46 ). Ventral surface moderately covered with dense and small brown spots, some spots with a short black hair in center, ventrite V sparsely covered with long black and brown hairs apically ( Fig. 47 ). Last segments of maxillary palp and labial palp broad and flat, truncate apically ( Fig. 49 ); frons with a narrow and mesial line extending from the base of clypeus up to the apical margin of the pronotum ( Figs 46 & 50 ); lower eye lobe semi-oval and longer than gena ( Figs 48 & 50 ); antennae 1.4 times as long as body, antennomere III longer than scape and nearly as long as IV; antennomeres V–VII subequal in length, antennomeres VIII–XI subequal in length. Scutellum rounded apically. Pronotum nearly as long as broad. Elytra distinctly broader than prothorax basally, 2.8 times as long as broad; disc moderately covered with dense and coarse punctures at basal 3/ 4, the punctures sparser and finer posteriorly, disappearing near apex; disc covered with reticulate texture ( Figs 51 & 52 ); marginal angles strongly horn-shaped. Apex of ventrite V with a curved notch in middle. Hind legs extending beyond elytral apex, metatarsal segment I shorter than II and III combined. Male terminalia. Tergite VIII ( Figs 53 & 54 ) sparsely covered with short and fine brown setae apically, with 3 long and thick black setae apically; disc slightly broader than long, slightly expanded in middle, rounded apically. Sternite VIII ( Figs 53 & 54 ) sparsely covered with short brown setae, broader than long; spiculum relictum nearly as long as sternite VIII. Spiculum gastrale ( Figs 53 & 54 ) Y-shaped, slender, distinctly longer than sternite VIII. Aedeagus. Tegmen ( Figs 55–57 ) curved, shorter than penis; parameres sparsely covered with short and fine brown setae apically, with several long and thick dark brown setae apically, ventral surface sparsely with short and fine brown setae at base; phallobase more than 4.0 times as long as parameres, abruptly expanded near apical 1/4, and gradually constricted towards base. Penis ( Figs 58–60 ) curved and thick in profile, paralleled (except for apex and dorsal struts); dorsal struts short, nearly 1/3 as long as penis, slightly curved in profile; dorsal plate rounded apically; ventral plate distinctly longer than dorsal plate, rounded apically. Female. Length: 13.2–14.0 mm; humeral width: 3.4–4.0 mm. Last segments of maxillary palp and labial palp conical at apical half ( Fig. 64 ). Antennae 1.2 times as long as body. Elytra 2.6–2.8 times as long as broad. Diagnosis. This new species is very close to E. plagiatoides in body color, shape and color of the spots on the elytra, elytra covered with reticulate texture ( Fig 51 & 52 ); but it can be distinguished from E. plagiatoides by the following characters: body shorter, elytra sparsely covered with short white pubescence at apex, with an inverted “V” white spot near apex, base of elytra broader than the base of pronotum.
