Holotype condition ( Figs 32 View FIGURE 32 , 33A–D View FIGURE 33 ). Right wing removed and mounted between coverslips and abdomen cut on T5 and removed; terminalia dissected and placed in microvial with glycerine pinned along with the specimen.

Taxonomic discussion. This species is very similar to Catostola carrerai comb. rev., and Catostola maya comb. rev., and can be differentiated from the first by the apex of the epandrial projection pointed distally ( Fig. 34E View FIGURE 34 ) and the apex of the gonocoxite with a small rod-like projection at the tip ( Fig. 35D–E View FIGURE 35 ) and from the second species by the less conspicuous femoral swelling on hind femora ( Fig. 37 View FIGURE 37 ) and by the more smooth indentation on epandrium dorsally at mid-length ( Fig. 34E View FIGURE 34 ) and the apex of gonocoxite not rounded and spatulate ( Fig. 35E View FIGURE 35 ).
