Male genitalia (Figs 9–12): epandrium 0.8 times as high as wide. Cerci small, the height and width almost equal, slightly separated distally, with small setae on the outer surface and one longer seta at apex. Surstylus nearly triangular in shape, 0.4 times the length of the genitalia, apex without spines. Hypandrium with 2 long setae at the apex. Distiphallus long, membranous. Female. Unknown. Distribution. China (Shaanxi). Etymology. The specific name “ macrocera ” refers to the long antennae. Remarks. The new species is similar to H. extensicornis Frey, but can be separated by the long, strong vibrissae; the interfrontal setae are also very strong and nearly parallel. In H. extensicornis Frey, the vibrissae are small and the interfrontal setae are small and crossed (Frey 1960).
