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. 44View FIGURES 44 – 51); fore wing covered by large brown pattern ( Fig. 51View FIGURES 44 – 51) which occupies cells cu 2, cu 1, m 2, m 1, apical 1 / 5 of r 2 and apical angle of r 1, cell m 1 rather short and wide; paramere with blunt apical tooth projecting caudad ( Fig. 48View FIGURES 44 – 51)................................................. C. (Hepatopsylla) liaoli 

-. Genal process about as long as vertex along median suture; fore wing without extended pattern indicated above, cell m 1 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, 13View FIGURES 9 – 16); female proctiger relatively long, setae rather short, apical part with many peg setae (in profile, over 50 on one side) ( Fig. 14View FIGURES 9 – 16)........................................................ 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, 5View FIGURES 1 – 8); female anus small, clearly less than half proctiger length ( Fig. 6View FIGURES 1 – 8)............................................................ 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, 24View FIGURES 20 – 29); female anus large, about half as long as proctiger ( Fig. 25View FIGURES 20 – 29)....................................................................................................... C. (Hepatopsylla) chinensis  [summer form]

5. Paramere relatively slender, apex tooth-shaped and moderately projecting cephalad ( Figs 22, 24View FIGURES 20 – 29, 35, 37View FIGURES 33 – 40); female subgenital plate without pattern ( Figs 25View FIGURES 20 – 29, 38View FIGURES 33 – 40)........................................................................ 6

6. Genal processes moderately divergent ( Fig. 20View FIGURES 20 – 29); marking near apex of claval suture of fore wing small, without light grey oblong marking in cell cu 2 ( Fig. 29View FIGURES 20 – 29); female proctiger weakly concave dorsally ( Fig. 25View FIGURES 20 – 29)................................................................................................. C. (Hepatopsylla) chinensis  [winter form]

-. Genal processes strongly divergent ( Fig. 33View FIGURES 33 – 40); marking near apex of claval suture large, with indistinct light grey oblong marking in cell cu 2, contacting with marking near apex of claval suture ( Fig. 40View FIGURES 33 – 40); female proctiger sinuous dorsally ( Fig. 38View FIGURES 33 – 40).................................................................... C. (Hepatopsylla) cinereosignata  sp. nov.

7. Genal process robust ( Fig. 52View FIGURES 52 – 59); fore wing oblong oval and clear, surface spinules present only in cell cu 2 ( Fig. 59View FIGURES 52 – 59); abdominal segments uniformly colored; female proctiger rising upward basally ( Fig. 57View FIGURES 52 – 59)................
