Recognition. This species is characterized by fronto-orbital setae not distinct; antenna mostly yellow, postpedicel darker dorsoapically; face with pruinescence restricted to antennal foveae; parafacial shiny; fore coxa and all femora dark; hind femur without anteroventral preapical setae; surstylus triangular, strongly tapered to narrow apex.

Description. Frons dark to reddish-brown band above antennae; gena dark. Face mostly shiny, with pruinescence restricted to antennal fovea; parafacial shiny. Fronto-orbital setae not distinct. Antenna mostly yellow, with dorsoapical margin of postpedicel darkened; antennal bases separated by slightly more than length of pedicel. Clypeus shiny.

Katepisternum with several stout ventral setae, anterior to mid coxa; short setulae on anterior half. Scutum shiny with dense setulae. Coxae and femora dark, with apex of femora pale; fore tibia and apical half of mid tibia pale; hind tibia mostly dark; tarsomeres on all legs pale; mid tibia with dark ventroapical seta, less than one-quarter length of tarsomere 1.

Male postabdomen ( Fig. 37View FIGURES 37–42): epandrium rounded, evenly sclerotized, setose. Hypandrium broad, with pair of short anterior setae; with rounded postgonite apically bearing strong marginal setae. Surstylus long, strongly tapered to narrow apex; apex arch posteromedially; setae confined mostly to posterior margin. Distiphallus tapered to narrow apex. Cercus elongate, longer than dorsal length of epandrium; apex rounded.

Female postabdomen ( Fig. 10View FIGURES 8–10): tergite 6 ( Fig. 38View FIGURES 37–42) with broadly bilobed anteriorly margin, slightly narrowed medially with sinuous posterior margin; posterior corners slightly prolonged with pair of long setae, more than half length of tergite; spermatheca ( Fig. 39View FIGURES 37–42) with long pigmented denticles or papillae; without end apparatus.

Distribution. This is the most widely distributed species, ranging as far north as Washington, south to Texas and Baja California ( Fig. 44View FIGURES 43–44).

Remarks. Several specimens have been taken from birds’ nests ( Malloch 1913; Wheeler 1959). Malloch (1913) included 14 specimens in the type series, but only nine were identified. The whereabouts of the remaining five specimens remains unknown.
