(Figs 1–8)
Ctenodontina Enderlein, 1914: 260.
Type species, Ctenodontina pectinatipes Enderlein, 1914 (original designation); Carrera & d’Andretta, 1953: 77 (new species, comments); Hull, 1962 (2): 480 (synopsis of world fauna); Martin & Papavero, 1970: 70 (catalogue); Lamas, 1972: 313 (catalogue); Lamas, 1973: 275 (new species, key); Artigas & Papavero, 1995: 36 (Lecania -group, catalogue; Papavero, 2009: 30 (catalogue); Vieira, 2012: 2, fig. 1 (new species, key); Vieira, 2014: 314 (female description, comments); Vieira, Ayala-Landa & Rafael, 2017: 290, figs. 1, 5 (new species, comments, key); Lamas & Camargo, 2021 (online catalogue); Sánchez & Camargo, 2021: 270, 278, figs. 1–3 (female description, key).
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.
