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

Distribution ( Fig. 8 View FIGURE 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 View FIGURE 8 ). Catostola baleta comb. nov., also occurs in the same valley in Colombia ( Fig. 44 View FIGURE 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 View FIGURE 1 , 7 View FIGURE 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.
