Key to the adults of Cyamophiliopsis species of China 1. Vertex (Fig. 2) much higher than gena by significantly protruding anterior margin, area right above the antennal insertion depressed. Genal processes (Fig. 2) relatively short, apex retracted, obliquely truncate. Lateral lobe of paramere (Figs 4 & 6) with sclerotised spines only in medial and apical portions, not in boundary with main part. Ventral bulge of female subgenital plate (Fig. 7) almost absent..................................................... C. zaisani (Klimaszewski, 1963) - Vertex higher than gena only at protruding anterior angle, area right above antennal insertion not depressed. Genal processes (Figs 16, 23, 31 & 38) relatively long, apex subacute. Lateral lobe of paramere with sclerotised spines on both margin and boundary with main part (Figs 19, 26, 34 & 41), or with semisclerotised setae. Ventral bulge of female subgenital plate distinct (Figs 20, 27, 35 & 42)................................................................................. 2 2. Forewing (Fig. 21) with light to dark brown marginal band across cells r2, m1, m2, cu1 and cu2 above Cu2, leaving uncolored breaches at the radular spinules fields in m1, m2 and cu1. Lateral lobe of paramere (Figs 17 & 19) with semisclerotised setae. Female subgenital plate (Fig. 20) relatively short........................................ C. pseudofasciata sp. nov. - Forewing without typical band-shaped marginal pattern as above; if with marginal pattern or infuscate margin, then definitely not leaving uncolored breaches at radular spinules fields in m1, m2 and cu1. Lateral lobe of paramere with sclerotised spines in margin and boundary with main part. Female subgenital plate relatively long...................................... 3 3. Lateral lobe of paramere (Figs 39 & 41) triangular, with emarginated anterior margin. Ventral bulge of female subgenital plate (Fig. 42) abruptly outstanding.......................................................... C. xinjiangana sp. nov. - Lateral lobe of paramere relatively plump in shape, anterior margin not emarginated, apical angle rounded. Ventral bulge of female subgenital plate relatively smooth.................................................................. 4 4. Genal processes (Fig. 31) rather robust, with lateral margins slightly convex rather than emarginated in dorsal view. Metatibial basal spine (same as in Fig. 10) blunt. Boundary between lateral lobe and main part of paramere (Fig. 34) with about 20 sclerotised spines. Peg setae on female subgenital plate (Fig. 35) short................................. C. spinosa sp. nov. - Genal processes (Fig. 23) more slender, with lateral margins slightly emarginated in dorsal view. Metatibial basal spine (Fig. 30) acute. Boundary between lateral lobe and main part of paramere (Fig. 26) with about 10 sclerotised spines. Peg setae on female subgenital plate (Fig. 27) relatively long, exceeding short setae........................ C. sarmatica (Löw, 1882)
