Type species.

Episymploce paradoxura Bey-Bienko, 1950: 157.

Diagnosis.

According to the traits proposed by Bey-Bienko (1950), Asahina (1979) and Roth (1986), this genus can be described as follows: the tegmina and wings are fully developed. Wings cubitus anterior vein has 1-5 complete and 1-6 incomplete branches, and the triangular apical area is small, reduced or absent. The first abdominal tergum can be specialized or unspecialized; the seventh abdominal tergum is always specialized; right and left lateral plates of the ninth abdominal tergum are similar, or the size and shape are obviously different, and the apex can be with or without small spines. The supra-anal plate is asymmetrical, symmetrical, or approximately symmetrical, the apex of the posterior margin is invaginated, or slightly concave; the subgenital plate is asymmetrical. The anteroventral margin of the front femora is of Type A3, rarely Type B, or between Type A and Type B. The male left aedeagus is in the shape of a hook.

Distribution.

Remarks. We agree with Roth (1987d), Wang (2006) and Liu et al. (2017) that E. taiwanica (Bey-Bienko, 1969) is a synonym of E. sundaica (Hebard, 1929), and agree with Roth (1987d) and Liu et al. (2017) that E. karnyi Princis, 1969 is a synonym of E. asahinai Roth, 1985. We also agree with Asahina (1979), Roth (1987d), Wang (2006) and Liu et al. (2017) that E. formosana formosana (Shiraki, 1907) is a synonym of E. formosana (Shiraki, 1907). So, E. taiwanica (Bey-Bienko, 1969), E. formosana formosana (Shiraki, 1907) and E. karnyi Princis, 1969 were not be included in the key below. Forty-one species in Episymploce , including all published 36 species, three subspecies and two newly described species are included in this key, which is adapted from Roth (1987d).
