Key to the genera of Psychodini known from the Afrotropical region

The following key works for most species of Psychodini known from the Afrotropical region, apart from a few discussed below as unplaced. It is, however, probable that several further genera remain unrecorded and/or undescribed.

1. Labellum flat, with row of apical ''teeth'' (e.g. Fig. 3 D)........................................................ 2

-. Labellum bulbous, without apical ''teeth'' (e.g. Fig. 1 A)........................................................ 4

2 (1). Surstyli with single distal tenaculum................................................... Psychoda Latreille, 1796

-. Surstylus with several tenacula in a distal transverse row...................................................... 3

3 (2). Ascoids with three branches. Genitalia symmetrical..................................... Neomaruina Vaillant, 1963

-. Ascoids with two branches. Genitalia asymmetrical........................ Rhipidopsychoda Vaillant, 1991 stat.restit.

4 (2). Tenacula in two groups; one group spatulate and one group filiform with complex apical expansions................................................................................................. Trichopsychoda Tonnoir, 1922

-. All tenacula generally spatulate, not expanded apically........................................................ 5

5 (4) Genitalia asymmetrical. Ascoids with two branches......................................... Threticus Eaton, 1904

-. Genitalia symmetrical. Ascoids with three branches.......................................................... 6

6 (5). Surstylus with two tenacula.......................................................... Philosepedon Eaton, 1904

-. Surstylus with three or more tenacula...................................................................... 7

7 (6). Flagellomere 11 without a neck. Hypoproct margin concave anteriorly at mid-point ( Fig. 1 G). Distiphallus not flattened, sepa- rate from parameres. Surstyli with 7 or more tenacula.................................... Perithreticus Vaillant, 1973

-. Flagellomere 11 with a short neck. Hypoproct margin straight anteriorly at mid-point ( Fig. 2 E). Distiphallus expanded into a flattened plate, overlapping with parameres. Surstyli with 3 tenacula............................... Soeliella gen.nov.
