Ctenodontina mochica Lamas, 1973: 276 View in CoL , 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 View Cited Treatment , 278, figs. 1–3 (female description, key).

Diagnosis. Face silvery pruinose; mystacal macrosetae white ( Figs 1A View FIGURE 1 , 3A View FIGURE 3 ); scape and pedicel dark yellow-brown; postpedicel and stylus brownish ( Figs 1A View FIGURE 1 , 3A View FIGURE 3 ); 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 View FIGURE 1 , 3A View FIGURE 3 ); 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 View FIGURE 1 ); an elongated concavity on proximal sixth of ventral surface of hind tibiae, opposite the femoral swelling ( Fig. 1B–C View FIGURE 1 ); abdomen yellow brown with silvery and golden pruinosity ( Fig. 1A View FIGURE 1 ); male terminalia reddish brown ( Fig. 1D–E View FIGURE 1 ), S8 with a mid-posterior projection bilobed apically ( Fig. 2D View FIGURE 2 ) and white setose apically ( Figs 1D–E View FIGURE 1 , 2A View FIGURE 2 ); epandrium with rounded apex, in lateral view ( Fig. 1D View FIGURE 1 ), with black and white setae ( Fig. 1D–E View FIGURE 1 ); gonocoxite subtriangular and rounded apically in lateral view ( Fig. 2F–G View FIGURE 2 ); hypandrium convex anteriorly and with a triangular indentation at posterior margin ( Fig. 2E View FIGURE 2 ); female terminalia compressed laterally and shining reddish brown ( Fig. 3B–C View FIGURE 3 ); T8 as long as T6 and T7 combined ( Fig. 3B–D View FIGURE 3 ); spermatheca with two oval capsules ( Fig. 3E View FIGURE 3 ). 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 View FIGURE 1 ). In addition, the S8 has a mid-posterior bilobed projection (Fig. D) which helps to separate it from Ctenodontina pectinatipes .
