Figures 5-16 , 17-27 Type species. Tempsarima bipunctata Chang & Chen, sp. nov., here designated. Diagnosis. This genus is similar to the genus Sarimodes Matsumura, 1916, but it differs from the latter by: 1) frons smooth (Fig. 9 ) (frons with verrucae along lateral margin and basal part in Sarimodes ( Meng and Wang 2016 : fig. 18)); 2) forewing with ScP vein long, reaching apical margin, and MP vein forked before the middle of forewings (Fig. 10 ) (forewing with ScP vein surpassing the middle of forewing, but not reaching apical margin; MP vein forked near distal part in Sarimodes (op. cit.: fig. 19)); 3) male genitalia with genital styles irregularly triangular in lateral view; anterodorsal and ventral margins parallel (Fig. 12 ) (genital styles irregularly rounded, dorsal and ventral margins not parallel in Sarimodes (op. cit.: fig. 22)); 4) apical part of dorsal lobe of phallobase with hooked process in lateral view (Fig. 15 ) (with sword-like process in Sarimodes (op. cit.: fig. 24)); 5) female anal tube and genitalia strongly developed and elongate, saw-like (Fig. 18 ) (not as above in Sarimodes (op. cit.: figs 28, 31)). Description. Body medium in size. Head and thorax . Width of head including eyes obviously narrower than pronotum (Fig. 7 ). Vertex (Fig. 7 ) irregularly quadrangular, shorter in middle than the maximum width in dorsal view, disc of vertex depressed, with median carina; anterior margin obtusely convex, posterior margin obtusely concave, lateral margins paralleled. Gena (Fig. 8 ) with one obvious ocellus between compound eye and antenna on each side in lateral view. Frons (Fig. 9 ) irregularly hexagonal, nearly flat, longer in middle than its maximum width, median carina stout and lateral carinae thin; without verrucae along basal margin and lateral margins; basal margin and frontoclypeal suture arched concaved, lateral margins not paralleled, the base narrow, the maximum width below level of antenna. Clypeus (Fig. 9 ) triangular, with stout median carina. Rostrum reaching mesotrochanters. Pronotum (Fig. 7 ) triangular, median carina stout, lateral carinae present, with sunken pits along median carina, anterior margin right-angle concaved, posterior margin straight. Mesonotum (Fig. 7 ) triangular, median carina obvious, lateral and sub-lateral carinae obscure. Forewings (Fig. 10 ) oblong, anterior and posterior margin nearly paralleled, apical margin relatively acute, longitudinal veins obvious, without obvious hypocostal plate; ScP long, reaching apical margin, nearly parallel with RP, ScP and RP have a common ScP+RP base, RP not forked, MP forking before middle of forewing, CuA forked into two branches near middle of forewing, CuP present, Pcu and A1 uniting near middle of clavus, clavus almost 4/5 of forewing. Hindwings (Fig. 11 ) well developed, three-lobed, Sc+RP have a common stem, forked near apical part, MP simple, not forked, CuA forked into branches CuA1 and CuA2 near apical part, CuA2 and CuP fused apically, with one transverse vein between RP and MP, MP and CuA1, Pcu and A11 anastomosing at a medium distance, Pcu, A11 and A12 simple, non-branched, A2 lobe developed, with A2 vein simple. Hind tibiae each with two lateral spines near distal half. Figures 5-16.

Abbreviations: a-irregular triangular prominence, b-small claviform process, c-convex protrusion, d-duck mouth-liked process, e-long hooked process, f-lobe-like process, g-small lamina-like process, h-mushroom-liked, i-short hooked process. Male genitalia . Anal tube (Fig. 13 ) elongate, longer than the maximum width in dorsal view. Anal style (Fig. 13 ) short, located near base, not surpassing the end of anal tube. Pygofer (Fig. 12 ) symmetrical, irregularly rectangular and broad, anterior and posterior margins parallel. Genital styles (Fig. 12 ) symmetrical, irregularly triangular in lateral view, anterodorsal and ventral margin nearly parallel, the width ca. 2.0 times than its height, bearing process near base of neck, neck of capitulum slender (Fig. 14 ). Phallobase (Fig. 15 ) symmetrical, shallowly "U" -shaped and tubular, stout, dorsal lobe developed with hooked process in lateral view. Aedeagus (Fig. 15 ) symmetrical, with one process in lateral view. Female genitalia (Figs 17-27 ). Anal tube (Fig. 20 ) sclerotized, extremely narrow, and obviously longer in middle line than the width, tapering in dorsal view. Anal style (Figs 17 , 20 ) long or short, located in base of anal tube, not surpassing the end of anal tube. Hind margin of gonocoxa VIII with endogonocoxal lobe not obvious, endogonocoxal process reduced, fused with anterior connective lamina of gonapophyses VIII (Fig. 22 ). Anterior connective lamina of gonapophyses VIII (Fig. 22 ) symmetrical, strongly sclerotized, extremely narrow, long, saw-like. Posterior connective lamina of gonapophyses IX (Figs 23 , 24 ) symmetrical, triangular, ventroposterior lobes with long flagelliform process. Gonoplacs (Figs 25 , 26 ) symmetrical, elongate, sclerotized, tuber and tapering in lateral view; the basal part fused in dorsal view. Hind margin of sternite VII convex, with prominence in middle area in ventral view (Fig. 27 ). Figures 17-27. Tempsarima bipunctata Chang & Chen, sp. nov. 17 female genitalia, dorsal view 18 same, lateral view 19 same, ventral view 20 female anal segment, dorsal view 21 same, lateral view 22 anterior connective lamina of gonapophyses VIII, lateral view 23 posterior connective lamina of gonapophyses IX, dorsal view 24 same, lateral view 25 gonoplacs, lateral view 26 same, dorsal view 27 sternite VII, ventral view. Scale bars: 1 mm ( 17-19 ), 0.5 mm ( 20-27 ). Abbreviations: tl-teeth in inner lateral margin, mf-median field, fp-flagelliform process. Distribution. China (Hainan). Etymology. The generic name is derived from a free combination between the genus names Tempsa Stal , 1866 (referring to the similar female genitalia) and Sarima Melichar, 1903 (type genus in Sarimini ). The gender is feminine. Remarks. The new genus markedly differs from the other genera in Sarimini : 1) frons smooth, with medical carina stout, reaching frontoclypeal suture (Fig. 9 ); 2) forewing with ScP vein long, reaching apical margin of forewings (Fig. 10 ); 3) male genitalia with genital styles irregularly triangular in lateral view, the width ca. 2.0 times the height (Fig. 12 ); 4) apical part of dorsal lobe of phallobase with hooked process (Fig. 15 ); 5) female genitalia with anal tube extremely narrow and long (Fig. 20 ), anterior connective lamina of gonapophyses VIII heavily sclerotized, long saw-like (Fig. 22 ), apical part of posterior connective lamina of gonapophyses IX with flagelliform process (Fig. 23 ), gonoplacs elongate, tubular in lateral view (Fig. 25 ).
