Diagnosis. Face slightly pronounced at oral margin ( Fig. 1A); ocellar tubercle with proclinate setae; palpus with one segment; postpedicel conical ( Fig. 5D); stylus weakly enlarged sub-apically ( Fig. 5A, C); thorax with 2 notopleural, 1 supra alar and 1 postalar macroseta ( Fig. 5G); scutellum without macrosetae, only with sparse and very short discal and marginal setae ( Fig. 5F); wings with bifurcation of R 4 and R 5 beyond discal cell; cells m 3 and cua closed and petiolate ( Figs 1A, 5E); legs yellow to reddish ( Figs 1A–C, 3A, 4A, 7); hind femur of males with a subrectangular projection with short and stout macrosetae ( Fig. 1A–C) or with 5 stout projections ending in black teeth ( Fig. 7); hind tibia of males with basal third curved with a ventral hollow ( Fig. 1A–C) or sigmoid ( Fig. 7A–B, F); terminalia reddish to black ( Figs 1D–E, 5H, 6); epandrial arms slender and thick up to the rounded apices; S8 with a mid-posterior projection bilobed apically ( Fig. 2D) or Y-shaped ( Fig. 6F) always ending before the apex of the epandrium; females with terminalia laterally compressed ( Fig. 3B–D); T8 as long as T6 and T7 combined ( Fig. 3B–D); two rounded spermathecae ( Fig. 3E); median sclerite present.

Distribution ( Fig. 8). Peru (Tumbes, Piura and La Libertad) and Colombia (Caldas). Ctenodontina mochica occurs in the west side of the Andes in a dry coastal area ( Lamas, 1973) and Ctenodontina pectinatipes in a valley between Cordillera Central and Oriental of the Andes in Colombia ( Fig. 8). Catostola baleta comb. nov., also occurs in the same valley in Colombia ( Fig. 44). So far, it is the only Catostola stat. rev. species that occurs in sympatry with Ctenodontina .

Taxonomic discussion. Ctenodontina can be distinguished from other genera of the Lecania -group mainly by the presence of very distinctive projections on the hind femur of males, ventrally, sub-apically, and with the anterior third of hind tibia in males curved or sigmoid ( Figs 1B–C, 7).

As previously pointed out by Hull (1962) and Sánchez & Camargo (2021) Ctenodontina seems to be more related to Lecania than to Catostola stat. rev.
