Type species: Psychomasina armata Ježek, 2004 , by original designation.

Psychomasina Ježek, 2004: 64 .

Revised diagnosis. Flagellomeres nodiform symmetrical to asymmetrical ( Figs 1 , 6 ). Sc elongate, nearly reaching C, R 5 terminating below wing apex; radial fork distal to medial fork; crossveins r-m and m-cu absent. Coxa of mid legs with distal mesal anterior protuberance covered with pores ( Fig. 3 ). Gonostylus with one to five setiform sensilla subapically on the mesal surface. Aedeagus with basiphallus narrow, distiphallus comprised of two symmetrical S- to G-shaped phallomeres with lateral and/or mesal spines; paramere sheath-like, with two parameral sclerites converging, fused medially, present as single needle-shaped protuberance.

Remarks. The median unpaired protuberance of the aedeagal complex originates from the gonocoxal condyles ( Fig. 4 ) and is therefore ontogenetically a paramere. An unpaired median elongate paramere also occurs in Pericomaini ; and a much shorter similar structure occurs in the Palaearctic genus Seoda Enderlein, 1935 (= Telmatoscopus auct., see KVIFTE 2014). Observations made in the present study support the hypothesis that Psychomasina represents a transitional form between Paramormiini and Pericomaini .
