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. 9View Figures 5–16) (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. 10View Figures 5–16) (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. 12View Figures 5–16) (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. 15View Figures 5–16) (with sword-like process in Sarimodes  (op. cit.: fig. 24)); 5) female anal tube and genitalia strongly developed and elongate, saw-like (Fig. 18View Figures 17–27) (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. 7View Figures 5–16). Vertex (Fig. 7View Figures 5–16) 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. 8View Figures 5–16) with one obvious ocellus between compound eye and antenna on each side in lateral view. Frons (Fig. 9View Figures 5–16) 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. 9View Figures 5–16) triangular, with stout median carina. Rostrum reaching mesotrochanters. Pronotum (Fig. 7View Figures 5–16) triangular, median carina stout, lateral carinae present, with sunken pits along median carina, anterior margin right-angle concaved, posterior margin straight. Mesonotum (Fig. 7View Figures 5–16) triangular, median carina obvious, lateral and sub-lateral carinae obscure. Forewings (Fig. 10View Figures 5–16) 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. 11View Figures 5–16) 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.

Male genitalia. Anal tube (Fig. 13View Figures 5–16) elongate, longer than the maximum width in dorsal view. Anal style (Fig. 13View Figures 5–16) short, located near base, not surpassing the end of anal tube. Pygofer (Fig. 12View Figures 5–16) symmetrical, irregularly rectangular and broad, anterior and posterior margins parallel. Genital styles (Fig. 12View Figures 5–16) 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. 14View Figures 5–16). Phallobase (Fig. 15View Figures 5–16) symmetrical, shallowly “U” -shaped and tubular, stout, dorsal lobe developed with hooked process in lateral view. Aedeagus (Fig. 15View Figures 5–16) symmetrical, with one process in lateral view.

Female genitalia (Figs 17-27View Figures 17–27). Anal tube (Fig. 20View Figures 17–27) sclerotized, extremely narrow, and obviously longer in middle line than the width, tapering in dorsal view. Anal style (Figs 17View Figures 17–27, 20View Figures 17–27) 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. 22View Figures 17–27). Anterior connective lamina of gonapophyses VIII (Fig. 22View Figures 17–27) symmetrical, strongly sclerotized, extremely narrow, long, saw-like. Posterior connective lamina of gonapophyses IX (Figs 23View Figures 17–27, 24View Figures 17–27) symmetrical, triangular, ventroposterior lobes with long flagelliform process. Gonoplacs (Figs 25View Figures 17–27, 26View Figures 17–27) 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. 27View Figures 17–27).

Distribution.

China (Hainan).

Etymology.

The generic name is derived from a free combination between the genus names Tempsa  Stål, 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. 9View Figures 5–16); 2) forewing with ScP vein long, reaching apical margin of forewings (Fig. 10View Figures 5–16); 3) male genitalia with genital styles irregularly triangular in lateral view, the width ca. 2.0 times the height (Fig. 12View Figures 5–16); 4) apical part of dorsal lobe of phallobase with hooked process (Fig. 15View Figures 5–16); 5) female genitalia with anal tube extremely narrow and long (Fig. 20View Figures 17–27), anterior connective lamina of gonapophyses VIII heavily sclerotized, long saw-like (Fig. 22View Figures 17–27), apical part of posterior connective lamina of gonapophyses IX with flagelliform process (Fig. 23View Figures 17–27), gonoplacs elongate, tubular in lateral view (Fig. 25View Figures 17–27).
