Orgilus californicus (Provancher 1888)

Orgilus californicus (Provancher)

Eubadizon californicus Provancher, 1888, p. 383.

Orgilus californicus (Provancher).—Muesebeck and Walkley, 1951, p. 111.

Superfically this seems most similar to cuneatus (Provancher), but the malar space is relatively much longer and the face broader, and the hind wing is relatively wide, with the lower abscissa of basella barely longer than the nervellus; in addition, californicus is much larger. I have seen no other specimen that I can confidently identify as californicus. The following notes are based on the female holotype.

Length about 4 mm. Head a little wider than thorax, in dorsal view about 0.6 as long as wide; face about 1.3 times as wide as eye height, mat, rather strongly sculptured and densely hairy, the hair punctures tending to form aciculae that converge obliquely on the meson; malar space conspicuously more than half as long as eye height, nearly 1.5 times as long as clypeus, and granulose and mat; cheeks shagreened and mat; temples smooth and shining near the eyes, somewhat shagreened adjacent to the occipital carina; antennae broken, but 28 segments of the right antenna remain, the last of these, like several of the preceding ones, slightly broader than long.

Mesoscutum shining, rather thickly hairy; propodeum largely very finely rugulose, but smooth and shining at base and in the apical lateral angles; mesopleuron smooth and shining, the longitudinal furrow foveolate; metapleuron shiny and nearly smooth above with only a little faint shagreening there, rugulose below. Hind coxa somewhat granulose and opaque; longer calcarium of hind tibia a little more than half as long as metatarsus; tarsal claws simple. Radial cell on wing margin about as long as stigma; second abscissa of radius on a line with intercubitus; nervulus a little postfurcal; hind wing not nearly five times as long as wide; lower abscissa of basella about as long as nervellus and much less than half as long as mediella or maximum width of hind wing.

Abdomen elongate, narrower than thorax; first and second tergites finely rugulose, the second nearly parallel-sided, the suture between it and the third sharply impressed; third tergite largely smooth and shining but with a small, finely, and confluently punctate area near base; ovipositor sheath about as long as propodeum and abdomen combined.

Black; antennae reddish yellow on basal half, the scapes darkened above; clypeus yellow on lower third; tegulae yellowish; legs brownish yellow, the hind coxae weakly darkened basally above; wings a little infumated; abdomen black but with conspicuous yellowish spots in the apical corners of the first and second tergites, the second tergite also rather broadly pale along the lateral margins.

MALE.—Unknown.

HOLOTYPE.—In the Quebec Provincial Museum collection, Laval University, Sainte Foy, Quebec.

DISTRIBUTION.—Known only from the holotype, which was taken at Los Angeles, California, by D. W. Coquillett.
