Ptychoderes magnus Mermudes and Napp, 2004: 27 , Figs. 1, 3 ; Rheinheimer, 2004: 10 (cat.).

Ptychoderes magnus was recently described and illustrated by Mermudes and Napp (2004). Here, the descriptions of the male and female terminalia are added.

Male terminalia. Tergite VIII ( Fig. 82 ) as long as wide, convergent at sides, widely rounded at apex; sternite VIII ( Fig. 96 ) strongly convergent apically, deeply emarginate at apex, apodeme triangular, weakly sclerotized; apodeme of sternite IX ( Fig. 110 ) twice as long as arms. Tegmen ( Fig. 124 ) rounded at apex. Aedeagus ( Figs. 173–176 ) without arc between apodemes; tectum ( Fig. 174 ) straight at proximal margin, acuminate at apex; pedon ( Figs. 173, 175 ) with body weakly curved, narrowed apically; apodemes weakly curved. Internal sac ( Fig. 173 ) slightly shorter than aedeagus, spiculated at distal two thirds, lateral membrane with pigmented rods; antemedian sclerites thickened and strongly sclerotized ( Fig. 176 ).

Female terminalia. Similar to that of P. jordani , differing by the emarginate apex of both tergite and sternite VIII.
