(Figs 1–3, 8)
Ctenodontina mochica Lamas, 1973: 276, 277, figs. 4–7; Artigas & Papavero, 1995: 36 (catalogue); Vieira, 2012: 2, fig. 1 (key); Vieira, 2014: 314 (comments); Vieira, Ayala-Landa & Rafael, 2017: 290, figs. 1, 4 (key); Sánchez & Camargo, 2021: 270, 278, figs. 1–3 (female description, key).
Diagnosis. Face silvery pruinose; mystacal macrosetae white (Figs 1A, 3A); scape and pedicel dark yellow-brown; postpedicel and stylus brownish (Figs 1A, 3A); thorax light yellow-brown; paramedian stripes, pre and postsutural spots and prescutellar spot dark; legs yellow brown with apex of last tarsomeres dark brown almost black (Figs 1A, 3A); hind femur with a conspicuous sack-like swelling on distal forth ventrally, bearing a number of short white spines on its apex (Fig. 1B–C); an elongated concavity on proximal sixth of ventral surface of hind tibiae, opposite the femoral swelling (Fig. 1B–C); abdomen yellow brown with silvery and golden pruinosity (Fig. 1A); male terminalia reddish brown (Fig. 1D–E), S8 with a mid-posterior projection bilobed apically (Fig. 2D) and white setose apically (Figs 1D–E, 2A); epandrium with rounded apex, in lateral view (Fig. 1D), with black and white setae (Fig. 1D–E); gonocoxite subtriangular and rounded apically in lateral view (Fig. 2F–G); hypandrium convex anteriorly and with a triangular indentation at posterior margin (Fig. 2E); female terminalia compressed laterally and shining reddish brown (Fig. 3B–C); T8 as long as T6 and T7 combined (Fig. 3B–D); spermatheca with two oval capsules (Fig. 3E). This diagnosis is based on the original description of Lamas (1973) and an additional description of the male terminalia and female by Sánchez & Camargo (2021).
Taxonomic discussion. Lamas (1973) described this species based on a single male specimen that seemed to him to be a newly hatched imago and that the colour-pattern could be somewhat darker in an older specimen. Recently Sánchez & Camargo (2021) described the female and provided an addendum to the description of the male terminalia of this species.
This species has a very conspicuous sack-like swelling on the distal fourth ventrally of the hind femora of males and the hind tibia is curved on the anterior third with a ventral hollow which seems to accommodate the femoral projection while in resting position (Fig. 1A–C). In addition, the S8 has a mid-posterior bilobed projection (Fig. D) which helps to separate it from Ctenodontina pectinatipes.
Distribution (Fig. 8). Peru (Tumbes, Piura and La Libertad).
