Recognition. This species is characterized by fronto-orbital setae distinct; antenna yellow; face mostly clothed in pruinescence, not extended beneath eye anteriorly; parafacial pruinose; legs dark; hind femur with 2 anteroventral preapical setae; surstylus triangular, arched posteriorly, strongly tapered to narrow apex.

Description. Frons dark brown without pale band above antennae; gena dark. Face mostly clothed in pruinescence, not extended beneath eye anteriorly; parafacial pruinose. Fronto-orbital setae distinct ( Fig. 15View FIGURES 15–18). Antenna yellow; antennal bases separated by length of postpedicel. Clypeus shiny.

Katepisternum with several stout, dark ventral setae, anterior to mid coxa; short setulae on anterior half. Scutum appearing smooth and shiny ( Fig. 27View FIGURES 27, 28); setulae not arising from tubercles. Legs with dark femora and mid and hind tibiae; fore tibia pale brown; tarsomeres 1 and 2 pale, increasingly darker apically. Mid tibia with dark ventroapical seta, one-quarter length of tarsomere 1. Hind femur usually with 2 spine-like preapical anteroventral setae ( Fig. 24View FIGURES 23–26).

Male postabdomen ( Figs 21, 22View FIGURES 19–22): epandrium rounded, evenly sclerotized, setose on posterior half; not extended ventrally. Hypandrium broad, with 1 anterior seta; with rounded postgonite apically. Surstylus long, arched posteriorly, strongly tapered to narrow apex; apex arched posteromedially; setae confined mostly to posterior margin. Distiphallus tapered to narrow apex. Cercus short, narrow, slightly longer than dorsal length of epandrium; apex rounded.

Female postabdomen: tergite 6 ( Fig. 20View FIGURES 19–22) broadly bilobed anteriorly, slightly narrowed medially with nearly straight posterior margin; posterior corners slightly expanded with pair of long setae, more than half length of tergite; spermatheca not examined.

Distribution. This species is known from several localities in Chile ( Fig. 29View FIGURE 29) in the Coquimban and Santiagan provinces of the Central Chilean sub-region (Morrone 2015).

Etymology. The species name refers to the two anteroventral spine-like setae on the hind femur.
