Myaptex Hull, 1962 (2): 508. Type species, Myaptex hermanni Hull, 1962 (original designation). Type locality: Chile, Concepción.

Remarks.

Myaptex is endemic to Chile and comprises only two species (Papavero 2009). The genus resembles Myaptexaria by the face distinctly gibbous, scutum with conspicuous rows of acrostichal setae and anterior dorsocentral macrosetae present, but can be easily segregated by the scutellar disc only with scattered, long setae (Fig. 13 B); normally two to four black apical scutellar macrosetae; male terminalia with epandria strongly inflated, their apices curved in apically (Figs 13 F, 14 A – D) in Myaptex versus scutellar disc with two tufts of abundant, proclinate, long setae (Fig. 15 B, C), from two to several apical scutellar macrosetae (sometimes mixed black and white) (Fig. 15 C), male terminalia with epandria not inflated, their apices blunt and not curved at apex (Fig. 15 F) in Myaptexaria . Myaptex is also superficially similar to Cardiasilus gen. nov. (see remarks under Cardiasilus gen. nov.), but the only feature they both share is the inflated male epandria (a feature that probably arose independently de novo in both genera).
