Key to males of Tichocoelidia

1 Inner dorsal processes of pygofer exceeding its apex ( Fig. 13 ); anal tube with ventral processes long, surpassing the ventral margin of the pygofer ( Figs 13, 20 )........................................................ T. vanessae sp. nov.

- Inner dorsal processes of pygofer not exceeding its apex ( Fig. 3 ); anal tube with ventral processes short, not surpassing the ventral margin of the pygofer ( Figs 3, 10 ).................................................................. 2

2 Aedeagus asymmetrical ( Figs 8–9 ); anal tube with ventral processes acute and sclerotized ( Figs 3, 10 ).................. 3

- Aedeagus symmetrical ( Chiamolera & Cavichioli 2003; Figs 1D–E ); anal tube with ventral processes robust and lobate, poorly sclerotized ( Chiamolera & Cavichioli 2003; Fig. 1B )........................ T. grandis Chiamolera & Cavichioli, 2003

3 Ventral margin of pygofer with a tooth in the basal third, pygofer inner dorsal processes thin and curved ventrally, apices not crossed ( Fig. 3 )........................................................................ T. marceloi sp. nov.

- Ventral margin of pygofer with a tooth in the median third of the ventral margin, pygofer inner dorsal processes robust and strongly curved internally, apices crossed ( Kramer 1962; Figs 10 , 12 ).......................... T. clarkei Kramer, 1962
