Length. Body: 16.5 mm; wing: 12 mm.

Female. According to Martin (1975): “…similar to the male, lateral margin of tergites more extensively grey than in male, the keel of S8 with spines, hypoproct with spines ventrally, numerous thin setae obscure the keel…” Female specimens of this species were not available for this study.

Variation. Hind femur with 2 anteroventral preapical black macrosetae.

Taxonomic discussion. In the examined paratypes 2 supra alar macrosetae were observed. However, a second and stout macrosetae can be observed in specimens of other Catostola species indicating that this character can be highly variable. Catostola martini comb. nov. can be distinguished from other species mainly by the combination of the following characteristics: the absence of a femoral swelling on hind femora of males ( Fig. 18A View FIGURE 18 ); hind femora entirely black ( Fig. 18A View FIGURE 18 ); the epandrium with a finger-like projection ( Figs 19E View FIGURE 19 , 20E View FIGURE 20 ) and the S8 with a mid-posterior rectangular projection ( Figs 19G View FIGURE 19 , 20D View FIGURE 20 ).

Distribution ( Fig. 44 View FIGURE 44 ). Mexico (Chiapas, Yucatán) and Guatemala (Escuintla, Suchitepéquez).
