1. Fore wing without marking near apex of claval suture…....................................................... 2
-. Fore wing with dark brown or black marking near apex of claval suture…......................................... 5
2. Genal process distinctly shorter than vertex along median suture (Fig. 44); fore wing covered by large brown pattern (Fig. 51) which occupies cells cu2, cu1, m2, m1, apical 1/5 of r2 and apical angle of r1, cell m1 rather short and wide; paramere with blunt apical tooth projecting caudad (Fig. 48)................................................. C. (Hepatopsylla) liaoli
-. Genal process about as long as vertex along median suture; fore wing without extended pattern indicated above, cell m1 relatively long and narrow; apical tooth of paramere projecting cephalad.......................................... 3
3. Fore wing with strongly contrasting surface spinules; paramere broad, with anterior margin expanding into a narrow elongate lobe (Figs 11, 13); female proctiger relatively long, setae rather short, apical part with many peg setae (in profile, over 50 on one side) (Fig. 14)........................................................ C. (Thamnopsylla) burckhardti sp. n.
-. Surface spinules of fore wing not contrasting; paramere relatively slender, without conspicuous extension; female proctiger relatively short, with several pairs of long setae, apical part with fewer peg setae (in profile, 20–30 on one side)........... 4
4. Body large, brown, more or less greenish; paramere relatively tubular, apex horn-shaped and relatively acute, several long, thick and erect setae growing from small tubercles present in anterior margin (Figs 3, 5); female anus small, clearly less than half proctiger length (Fig. 6)............................................................ C. (C.) accincta sp. n.
-. Body small, yellow to green; paramere relatively lamellar, apex tooth-shaped, without the setae mentioned above in anterior margin (Figs 22, 24); female anus large, about half as long as proctiger (Fig. 25)....................................................................................................... C. (Hepatopsylla) chinensis [summer form]
5. Paramere relatively slender, apex tooth-shaped and moderately projecting cephalad (Figs 22, 24, 35, 37); female subgenital plate without pattern (Figs 25, 38)........................................................................ 6
-. Paramere relatively robust, apex rounded and projecting caudad (Figs 54, 56, 62, 64); female subgenital plate with very solid dark brown pattern (Figs 57, 65).......................................................................... 7
6. Genal processes moderately divergent (Fig. 20); marking near apex of claval suture of fore wing small, without light grey oblong marking in cell cu2 (Fig. 29); female proctiger weakly concave dorsally (Fig. 25)................................................................................................. C. (Hepatopsylla) chinensis [winter form]
-. Genal processes strongly divergent (Fig. 33); marking near apex of claval suture large, with indistinct light grey oblong marking in cell cu2, contacting with marking near apex of claval suture (Fig. 40); female proctiger sinuous dorsally (Fig. 38).................................................................... C. (Hepatopsylla) cinereosignata sp. nov.
7. Genal process robust (Fig. 52); fore wing oblong oval and clear, surface spinules present only in cell cu2 (Fig. 59); abdominal segments uniformly colored; female proctiger rising upward basally (Fig. 57)................ C. (Hepatopsylla) maculatili
-. Genal process slender (Fig. 60); fore wing oval, apical 2/3 appearing yellowish, surface spinules present in all cells (Fig. 67); terga of abdominal segments III–V dark brown, differing from other light yellow segments; female proctiger not rising upward basally (Fig. 65).................................................................... C. (Hepatopsylla) qiuzili
