(Figs. 1, 5–13, 43)
Diagnosis. The species is characterized in the male by the proximal endophallus possessing dorsolaterally a pair of obtuse processes that lack bristle tufts, and in the female by the presence of a slightly sclerotized disc anterior to the suboval sclerite of the subgenitale.
Description. Male. Forewing length 6.0–8.0 mm.
Head subquadrate, blackish brown, clypeus yellowish brown, vertex laterally with two pairs of indistinct brownish cuneate markings and medially with a pair of reddish brown vittae. Antennal sclerite (torulus), scape, and pedicel yellow; flagellum pale brown. Mouthparts pale brown.
Thorax blackish brown; meso- and metanota each with a yellowish marking anteromedially, and with a yellowish transverse marking on posterior margin of scutellum. Legs yellow with yellowish setae, coxae pale brown. Wings hyaline, pterostigma pale brown, veins pale brown. Anterior branch of Rs with two simple veins running to wing margin.
Abdomen blackish brown, venter slightly paler; each pregenital segment with a narrow yellowish transverse marking on posterior margins of tergite and sternite; genital segment blackish brown with ectoproct margined yellow, gonocoxite brown. Ninth gonocoxite (Figs. 5–7) shell-like, nearly semicircular, slightly wider than long; subdistal portion of inner side dorsally with a small blunt stylus bearing a bristle tuft, an additional bristle tuft lies anterior to the stylus, and two bristles are present ventrally near posterior margin. Pseudostyli (gonapophyses 9) paired and foliate (Fig. 6). Fused parameres (complex of fused gonocoxites, gonapophyses, and gonostyli 10) (Figs. 7, 9) small, proximal portion flattened and roundly expanded, distal projection slightly curved dorsad with tip not concave. Gonarcus (fused gonocoxites 11) (Figs. 6–8) shieldlike, with dorsal margin produced posteriad, in caudal view subtrapezoidal, bearing four short setae. Endophallus (Figs. 6–7) short, smooth throughout, sometimes with a pair of short bristles laterally on dorsal portion, proximal portion dorsally with a pair of obtuse processes laterally. Ectoproct nearly rounded in lateral view (Fig. 5). Hypandrium internum (Fig. 10) small with considerably narrow lobes.
Female. Forewing length 7.0–10.0 mm.
Seventh sternite (Figs. 11–12) subtrapezoidal in lateral view, posteriorly produced; in ventral view posterior portion narrowed with posterior margin truncate or feebly incised. A feebly sclerotized broad disc, which is concave on anterior margin (Figs. 11–12), presented anteriorly to narrow suboval sclerite of subgenitale. Ectoproct (Fig. 11) subtrapezoidal in lateral view. Atrium bursae (Fig. 13) subtriangular; sacculus bursae tubular; receptaculum seminis long, with a pair of short ovoid glandula receptaculi distad.
Specimens examined. Holotype 3 [pinned], CHINA: Shandong Prov., Tai-an, Daimiao [36°11΄N, 117°07΄E], 24.IV.1963, X. Zhao (CAU). Paratypes: 1733Ƥ [pinned], same data as holotype (CAU); 332Ƥ [pinned], CHINA: Shandong Prov., Tai-an, Daimiao, 22.IV.1963, X. Zhao (CAU); 234Ƥ [pinned], CHINA: Shandong Prov., Tai-an, Daimiao, 26.IV.1963, X. Zhao (CAU); 131Ƥ [preserved in alcohol], CHINA: Shandong Prov., Tai-an, 27.IV.1963, M. Zhou (CAU).
Distribution. China (Shandong Prov.). Biogeographically (in the sense of de Lattin 1967) the species probably represents a stationary Manchurian faunal element of the Ussurian secondary refugial center.
Etymology. The specific epithet ‘biprocessus’ refers to the two processes on the male endophallus of the new species. It is a noun in the nominative singular being an apposition to the genus name Inocellia.
Remarks. The new species appears to be related to I. japonica by the similar male endophallus which proximally bear a pair of dorsolateral processes. This assessment stands in conflict with the previously wellestablished sister group relationship of I. japonica and I. crassicornis. However, it is also questionable to interpret the processes of the endophallus to have resulted from parallel evolution in the new species and I. japonica, and a monophyletic subgroup including the three species with internal polymorphism might be a better assumption at present considering their relationships. Inocellia biprocessus can be distinguished from both species by the male endophallus bearing no bristle tufts (or only a few bristles) and in the female by the presence of the sclerotized disc located anteriorly to the suboval sclerite of the subgenitale.
