Fig. 96

Diagnosis

The palpal organ of this species is similar to that in Thyene striatipes (Caporiacco, 1939) , but can be recognized by the thinner and longer apophysis. 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 .
