Inocellia rara sp. nov. (Figs. 1–10) Description. Male. Forewing length 7.8 mm. Head (Fig. 1) subquadrate, black, vertex medially with a pair of yellowish brown longitudinal vittae; clypeus reddish brown. Antennal sclerite (torulus) yellowish brown; antennae brown except for scape, pedicel and proximal four flagellomeres which are yellowish brown. Mouthparts reddish brown. Thorax (Fig. 1) black; meso- and metanotum each with a yellowish brown marking medially anterior to yellowish brown scutellum. Legs yellowish brown, slightly darker on tibiae, with yellowish setae. Wings hyaline, pterostigma pale brown, veins brown. Rs with one forked vein and one simple vein running to wing margin. Abdomen (Fig. 1) blackish brown; each pregenital segment with yellowish transverse marking on posterior margin of both tergite and sternite; genital segments brown, but tergum 9 much darker and ectoproct yellow. Tergum 9 (Fig. 2) approximately twice as long as sternum 9, anterior margin slightly incised medially, posterior margin shallowly incised. Sternum 9 (Fig. 4) arcuate, with anterior margin prominent. Gonocoxite 9 (Figs 2–5) shell-like, moderately longer than width of its proximal portion, with apex rounded in lateral view; stylus (gonostylus 9) present subdistad on inner side of gonocoxite 9, short and subtriangular with apex rounded and covered by an inconspicuous dentation, proximally slightly protruding dorsad, which is visible only in lateral view, and digitiform, obliquely directed anteriad in both dorsal and ventral view. Pseudostyli (gonapophyses 9) (Figs 4– 6) feebly sclerotized, foliate, slightly curved anteriorly in ventral view. Fused parameres (complex of gonocoxites, gonapophyses, gonostyli 10) (Figs 5–6, 8) flattened on proximal portion with marginal area curved posteriorly, ventrally bearing a slender and long distal projection, which is slightly curved dorsad and bifurcated at tip. Gonarcus (fused gonocoxites 11) (Figs 4–7) broad, subtrapezoidal and arcuately concaved on ventral margin in caudal view, dorsally with a distally bifurcated projection, and ventrally with a pair of small denticulate processes. Endophallus (Figs 4–6) short, lateral portions distally with a pair of bristle tufts directed anterodorsad and proximally with a pair of bristle tufts directed anteroventrad. Scabrous membranous, narrowly foliate serratulum present (Figs 4–6). Ectoproct (Figs 2–3) subquadrate in lateral view. Hypandrium internum (Figs 6, 9) small with lateral lobes foliate and slightly sinuated posteriorly. Type material. Holotype ♂, CHINA: “North Formosa [= Taiwan], Mt. Taihei [= Mt. Taipingshan in Yilan County, 24°29′50.26″N, 121°32′2.23″E], 2300 m, 28.VI.1941, Coll. T. Sato” (NIAES). Etymology. The specific epithet “ rara ” refers to the rareness of this new species. It is an adjective in the nominative feminine singular. Distribution. (Fig. 10) This new species is currently known only from its type locality, i.e. Mt. Taipingshan, in northern Taiwan, China. Remarks. The new species clearly belongs to the I. fulvostigmata species group due to the male gonocoxite 9 which is wider than long and the presence of a scabrous membranous serratulum (see identification key to species of Inocellia in Liu et al. 2012b). The new species appears to be closely related to Inocellia sinensis Navás in having similar male genitalia with the gonocoxite lacking inner bristle tuft, the fused parameres bearing long distal projection, and the double protruding gonarcus. Inocellia rara sp. nov. can be distinguished from I. sinensis by the male gonocoxite 9 with a subtriangular stylus, which is rounded and covered by a number of tiny dentations distally, and by the gonarcus with a pair of projections near dorsal margin and with arcuately concaved ventral margin. In I. sinensis, the stylus of male gonocoxite 9 is unguiform, without any dentations, and the gonarcus has a pair of projections at middle but lacks distinctly concaved ventral margin.
