The bulb flap is directed horizontally in Thyene perfecta sp. nov. and vertically in T . striatipes (compare Fig. 96C with Prószyński 1987 : fig. on p. 114). Etymology The specific name is Latin and refers to the fact that it perfectly represents the genus Thyene . Fig. 96. Thyene perfecta sp. nov. , holotype, ♂ (ZFMK 2876). A . General appearance. B–C .
