Key to species of genus Trachypeplus occurring in China

1. Body elongate-ovate ( Figs.1–8 ); costal area relatively broad, bi- or triseriate; rostral sulcus not parallel, cordate on metasternum, or nearly parallel but relatively broad ( Figs. 29–33 )...................................................... 2

- Body nearly parallel-sided ( Figs. 9–11 ); costal area narrow, uniseriate at its length; rostral sulcus much narrow, straight, nearly

parallel ( Figs. 34–36 )..................................................................................7 2. Paranota along the lateral margins of pronotum folded a longitudinal ridge, these divided paranota into two parts, ventral and dorsal...................................................................... Trachypeplus depressus sp. nov.

- Paranota without such longitudinal ridges.................................................................. 3

3. Body dorsally armed with many tubercle-spines, especially on paranota and outer margins of hemelytra ( Figs. 4–6 )........ 4

- Body dorsally not armed with such tubercle-spines, or with very few tubercle-spines on the anterior part of paranota ( Figs. 1– 3 , 7–8 ).............................................................................................. 5

4. Hood relatively large, with the dorsal margin arched distinctly in lateral view ( Fig. 15 ); tubercle-spines on hood, paranota and hemelytra short, the tubercle nearly equal to spine; rostral sulcus on mesosternum nearly parallel, but widened on metasternum, there cordate ( Fig. 33 )........................................................ T. jacobsoni Horváth, 1926

- Hood relatively small, flattened above, with the dorsal margin nearly straight in lateral view ( Fig. 14 ); tubercle-spines on hood, paranota and hemelytra long, the tubercle two times as long as spine; rostral sulcus nearly parallel, but slightly widened posteriorly ( Fig. 32 )........................................................................... T. jingae sp. nov.

5. Paranota relatively broad, quadriseriate, widest distance between outer margins and lateral carinae narrower than or nearly equal to that between lateral and median carinae ( Fig. 21 )............................. T. malloti Drake and Poor, 1936

- Paranota relatively narrow, bi- to triseriate, widest distance between outer margins and lateral carinae much distinctly wider than that between lateral and median carinae ( Figs. 22–23 )..................................................... 6

6. Dorsal margin of hood arched in lateral view ( Fig. 13 ); ridges of areolae on paranota covered with many small tubercle-hairs ( Fig. 7 b); costal area relatively broad, mostly triseriate ( Fig. 7 a)............................... T. parafulgoris sp. nov.

- Dorsal margin of head near straight in lateral view ( Fig. 16 ); paranota without such tubercle-hairs ( Fig. 8 b); costal area relatively narrow, uniformly biseriate at its length ( Fig. 8 a)..................................... T. fulgoris (Drake, 1937)

7. Body relatively small, length less than 3.0 mm ( Figs. 9 ); median portion of M+R vein on hemelytra raised, these black; each paratergite IX of female with an outer process ( Figs. 41 )..................................... T. chinensis Drake 1936

- Body relatively large, length more than 3.0 mm ( Figs. 10–11 ); median portion of M+R vein on hemelytra not raised; each paratergite IX of female without such outer process ( Figs. 42–43 )...............................................8

8. Paranota relatively broad, five areolae broad at widest part, with outer margins anteriorly and posteriorly nearly in contact with lateral carinae ( Fig. 27 ); transverse crest of paranota greatly elevated, distinctly higher than median carina ( Fig. 18 ); three carinae slightly and uniformly raised at its length, median carina nearly as high as lateral carinae......... T. magnus Jing, 1981

- Paranota relatively narrow, four areolae broad at widest part, with outer margins of paranota anteriorly and posteriorly separating from lateral carinae by a distinct space, or only anteriorly nearly in contact with lateral carinae ( Fig. 28 ); transverse crest of paranota elevated, but lower than median carina ( Fig. 19 ); median carina on top of pronotal disc distinctly elevated, there biseriate, higher than lateral carinae......................................................... T. yunnanus Jing, 1980
