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) . FIGURE 1.

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 ).
