Psychomasina Ježek, 2004

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 .
