Type material. HOLOTYPE Ƌ, labelled: “ Socos / Coquimbo, CHILE / 1.XI.1957 / L.E. Peña ”; “ HOLOTYPE / Paraleucopis / bispinosa/ Wheeler & Sinclair [red label]” (CNC). PARATYPES: Chile: Coquimbo, Rivadavia, 29.x.1957, L.E. Peña (2 ♀, CNC); Linares, Linares, xii.1952, L.E. Peña (1 Ƌ, CNC); Atacama, 20 km S Vallenar, 13.x.1969, Rozen & Peña (1 Ƌ, AMNH); 5 mi. N Illapel, 30.xi.1950, Ross & Michelbacher (1 Ƌ, 1 ♀, CAS); 50 km S La Serena, 1.xii.1950, Ross & Michelbacher (4 Ƌ, 1 ♀, CAS).
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. 15). 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. 27); 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. 24).
Male postabdomen (Figs 21, 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. 20) 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. 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.
