Key to the known species of the subgenus Cardiobioramix from China

1. Pronotum widest near to or at the base.................................................................... 2

- Pronotum widest at the middle or more anteriorly............................................................ 3

2. Pronotum widest just before the base. Pronotal base nearly straight. Protarsi slightly widened, nearly as wide as protibiae. Parameres gradually narrowing towards apex. Phallobase ca. 1.6 times as long as parameres, not S-curved in lateral view, nearly straight......................................................... .. Bioramix szetschuana ( Kaszab, 1940)

- Pronotum widest at the base. Pronotal base shallowly bisinuate. Protarsi strongly widened, wider than protibiae. Parameres sharply narrowed in apical 1/4 and nearly parallel-sided up to distal end. Phallobase ca. 2.2 times as long as parameres, strongly curved in lateral view................................................. Bioramix splendida Egorov, 2006

3. Anterior margin of pronotum slightly sinuate or nearly straight.................................................. 4

- Anterior margin of pronotum deeply sinuate................................................................ 7

4. Pronotal base strongly arcuate. Anterior and posterior angles of pronotum sharp and rectangular. Parameres with moderately narrowed apical part, not S-curved in lateral view, nearly straight.................. Bioramix korschefskyi ( Kaszab, 1940)

- Pronotal base straight or shallowly bisinuate. Anterior angles of pronotum obtuse, posterior angles sharp and rectangular or weakly obtuse. Parameres with slightly S-curved in lateral view................................................. 5

5. Pronotal base straight. Protarsi slightly widened, nearly as wide as protibiae. Metatibiae straight. Parameres gradually and almost straightly narrowing towards apex, with sharp apices.......................... Bioramix asidioides Bates, 1879

- Posterior margin of pronotum slightly sinuate. Protarsi strongly widened, wider than protibiae. Metatibiae slightly incurved. Parameres with rounded apices.......................................................................... 6

6. Elytra with distinct bronze shine. Anterior half of outer margin of epipleura visible from above. Protibiae nearly straight. Parameres almost straightly narrowing in basal 1/2, shallowly sinuate before distal 1/2, with very rounded apices.................................................................................. Bioramix championi ( Reitter, 1891)

- Elytra with very weak bronze shine. Outer margin of epipleural visible dorsally at base. Protibiae weakly curved in basal 1/3. Parameres gradually and almost straightly narrowing in basal 2/3, shallowly sinuate before distal 1/3, with widely rounded apices......................................................................... Bioramix kabaki Egorov, 2006

7. Elytral punctures with coarse setae in the middle. Traces of rows on elytral surface almost invisible. Dorsal surface of each elytron with 3 longitudinal carinae. Parameres strongly narrowing apically; with obtused apices.................................................................................................. Bioramix kulzeri ( Kaszab, 1960)

- Elytral punctures with fine setae, almost invisible or visible only at elytral declivity. Elytral surface with noticeable traces of distinct rows. Parameres slightly narrowing apically; with rounded or sharp apices................................. 8

8. Anterior half of the outer margin of epipleura visible dorsally. Protarsi strongly widened, wider than protibiae............ 9

- Only basal part of the outer margin of epipleura visible dorsally. Protarsi slightly widened, nearly as wide as protibiae.... 10

9. Anterior margin of clypeus weakly, but noticeably arcuate in the middle. Antenna long, with three apical segments reaching beyond pronotal base. Elytral surface with rows of sparse punctations much larger than those on rest of elytral surface. Inner surface of protibiae covered with coarse setae. Parameres elongated, S-shaped curved distal part than all other congeners............................................................................... Bioramix jinchuanensis sp. nov.

- Anterior margin of clypeus straight. Antenna short, with two apical segments reaching beyond pronotal base. Elytral surface with rows of sparse punctations as large as or slightly larger than those on rest of elytral surface. Inner surface of protibiae not covered with setae. Outer margins of parameres evenly narrowing towards apex, not S-curved in lateral view, nearly straight.

.................................................................... Bioramix subaenescens ( Schuster, 1923)

10. Antenna short, with only the apical segment reaching beyond pronotal base. Elytral surface with traces of rows of punctations as large as or slightly larger than those on rest of elytral surface. Metatibiae weakly incurved. Parameres almost parallel to the basal part and then gradually tapered to the apex.................................... Bioramix maoxianensis sp. nov.

- Antenna long, with two apical segments reaching beyond pronotal base. Elytral surface with distinct rows of punctations much larger than those on rest of elytral surface. Metatibiae straight. Parameres moderately narrowed in apical part..................................................................................... Bioramix chinensis ( Kaszab, 1940)
