Recognition. This species is characterized by fronto-orbital setae not distinct; antenna yellow; face with pruinescence on upper half; parafacial with pruinescence; clypeus shiny; gena mostly shiny, pruinosity not extended posteroventrally below eye; fore coxa and all femora dark; hind femur without anteroventral preapical setae; surstylus L-shaped, with broad rectangular base bearing several strong setae.

Description. Frons dark to reddish-brown band above antennae; gena dark. Face with pruinescence on upper half ( Fig. 13 ); parafacial pruinose. Fronto-orbital setae not distinct. Antenna mostly yellow, with apical half of postpedicel darkened; antennal bases separated by more than length of pedicel. Clypeus shiny.

Katepisternum with several stiff, dark 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 mostly pale; mid and hind tibiae darkened in middle, pale basally and apically; tarsomeres on all legs pale, except darkened tarsomere 5 dorsally; mid tibia with dark ventroapical seta, less than one-quarter length of tarsomere 1.

Male postabdomen ( Figs 33, 34 ): epandrium rounded, evenly sclerotized, setose. Hypandrium broad, with pair of long anteriorly setae; with narrow and rounded postgonite apically. Surstylus L-shaped, with broad rectangular base bearing several strong marginal setae; apex slightly curved medially. Distiphallus tapered to narrow apex. Cercus rounded, width subequal to length, shorter than dorsal length of epandrium.

Female postabdomen: tergite 6 ( Fig. 35 ) bilobed anteriorly, slightly narrowed medially with slightly sinuous to straight posterior margin; with 2 pairs of long setae, longer than half length of tergite; spermatheca ( Fig. 36 ) with long pigmented denticles or papillae; without end apparatus.

Distribution. This species is known only from California, USA ( Fig. 43 ).
