Diagnosis.

This new species is recognized easily by the elytra of males possessing a lateral cavity near each lateral margin and the pygidium of each female with deeply emarginated apex.

Males.

Length 6.2-6.3 mm, width 3.6-3.7 mm. General color (Figs 1-3) yellowish brown; antenna dark brown; scutellum black; elytra pale yellow, with one small, longitudinal black spot at humerus, one large, rounded black spot at postermedian area, apex black; mesepimeron and metathoracic ventrites black; outer margins of femora and tibiae black; tarsi dark brown. Elytron with one premedian cavity near lateral margin; three tufts of long hairs at anterior area and one tubercle at posterior of depression; postscullar common area flat and impunctate. Eighth abdominal tergite (Fig. 12) strongly sclerotized, base extremely slender, with one pair of extremely long processes, each process flattened and widened near apex and outer margin of widened area serrate. Pygidium projecting beyond elytral apices, apex shallowly emarginate. Penis (Figs 10-11) strongly asymmetric, dorsum with longitudinal groove at right side; almost straight from lateral view; apex forming angular process and directed ventrally; endophallic sclerites with two sclerites, one extremely elongate, about 0.75 times as long as penis, other curved and apically pointed.

Females.

Length 6.2-6.9 mm, width 3.5-3.7 mm. Color (Figs 4-5) similar to male but elytra without excavation. Apical margin of last abdominal ventrite (Fig. 14) with deep notch at middle, between one pair of shallow processes. Pygidium projecting beyong elytral apices, deeply emarginate and forming bilobed process. Gonocoxae (Fig. 13) slender, apex of each gonocoxa with eight to nine setae from apical 1/4 to apex; connection of gonocoxae extremely slender, base slender. Sternite VIII (Fig. 15) weakly sclerotized; apex wide, apical margin truncate, surface with extremely dense long setae along apical margin, spiculum short. Spermathecal receptaculum (Fig. 16) strongly swollen; pump much longer than receptaculum, strongly curved; spermathecal duct short, stout, shallowly projecting into receptaculum.

Etymology.

The new species name honors Mr. Hou-Jay Chen, who discovered this interesting new species.

Distribution.
