Holotype condition (Figs 22, 23C–D, 26A–B). Postpedicel (Fig. 22D) and left hind leg missing (Fig. 22A); right eye damaged (Fig. 22C), right wing damaged anteriorly, right mid femur crossed by pin, last 2 tarsomeres of right mid leg missing; abdomen cut on T4 and dissected, dissected parts in microvial pinned with the specimen.

Female. Carrera & d’Andretta (1953) mention only that the female is similar to the male with hind femora smooth without the spinous callosity.

Variation. Only one supra alar macrosetae.

Taxonomic discussion. Postpedicel, abdomen after T3 and male terminalia were redescribed based on additional material. The female paratype (Tingo Maria, 670 m, april-1947, Weyrauch) mentioned by Carrera & d’Andretta (1953) was not located during visits to the Diptera collection of the MZUSP.

This species can be easily separated from other Catostola species by the presence of a well-developed femoral swelling ventrally on hind femur of males (Fig. 26). The most similar species are Catostola carrerai comb. rev., and Catostola sagta comb. nov. These two species have a smaller and less conspicuous swelling on male hind femora (Figs 14C, 37) and can be differentiated from C. maya comb. rev., by the epandrial arm with an indentation dorsally at mid-length (Fig. 24E) and the rounded, spatulate apex of the gonocoxite (Fig. 25D–E).
