Phortica (Phortica) omega ( Okada, 1977)

( Fig. 22 )

Amiota (Phortica) omega Okada, 1977: 21 ; Chen & Toda 1998: 404.

Diagnosis. This species is very similar to P. perforcipata Máca, 1993 in the male terminalia and having the abdominal sixth tergite with 1 distinct, prickly process on anterior corner of lateral margin ( Fig. 22A ), but can be distinguished from the latter by having the posterior branch of paramere slender, narrower than anterior branch, and the anterior branch slightly expanded subapically ( Fig. 22D ).
