Chaetotaxy: antepronotal macrosetae and setae pale yellow with a few, very short black setae posteriorly; 2 notopleural; 1 supra alar; 1 postalar and 3 pairs of dorsocentral black postsutural macrosetae; scutum with short black acrostichal setae and thin yellowish setae on postpronotal lobe, anteriorly; scutellum with short sparse black discal and marginal scutellar setae (Fig. 17B); anepisternum with short, thin yellowish and black setae dorsally; katatergite with white macrosetae and setae; remainder of pleura with thin and very sparse whitish setae.
Wings (Fig. 17A): translucent, apical third slightly yellowish translucent; veins dark brown; R 4 slightly rounded in the junction with R 5; bifurcation of R 4 and R 5 beyond discal cell at a distance equivalent to the length of two crossvein r-m; crossvein r-m shortly after the middle of discal cell at a distance equivalent to the length of one crossvein m-m; cells m 3 and cua closed before wing margin. Halteres: yellow, knob dark yellow.

Taxonomic discussion. This species can be differentiated from other Catostola species mainly by the yellow legs with apical third of mid and hind femora dark brown (Figs 16A–B, 17C) and the epandrium with a long, finger-like dorsal projection (Fig. 17D–G). The most similar species is Catostola baleta comb. nov. that can be distinguished through epandrial finger-like projection which is constricted short before the mid-length of the epandrium with the projection slightly longer than half of epandrial length (Fig. 17D–E) and the S8 mid-posterior projection which is slightly constricted at the base (Fig. 17G).
Distribution (Fig. 44). Honduras (Atlántida). The original description was based on one holotype and two paratypes from the same locality as the holotype but collected on May 2, 1923 (James, 1953). In this study, only the holotype was examined.According to Erika Tucker (in litt., 2019), curator at the University of Michigan Museum of Zoology (UMMZ), the paratypes were not located in the respective collection and its whereabouts are unknown.
