Holotype male: Length 11 mm.
Head: black; face and frons densely golden tomentose, gray pollinose spot laterally at base antennae; occiput golden pollinose at eye margins fading to gray; palpi and proboscis black. Mystax black with few brownish white setae in center; setae of frons, ocellar tubercle, upper occiput, entire eye margin, first two antennal segmenss, and second palpal segment black; beard, setae of proboscis and first palpal segment white. First two antennal segments and style black; third orange; first segment 1 1/5 times longer than second; third 1 1/3 times length first two segments together; style with apical spine one fourth length third; two strong black bristles subapically below on second point, slender third bristle also present.
Thorax: largely shining black, brown pollinose; spots of golden tomentum at base postpronotal lobe, below on notopleura, below supraalar bristles, parallel to midline behind transverse suture and centrally at apex of mesonotum; pair central stripes light brown pollinose bisected by narrow golden tomentose median stripe Setae and bristles mesonotum and scutellum black; 2 notopleurals, 5–6 supraalars, and 4 postalars. Scutellum largely shining black with spot of golden tomentum at base. Pleura and coxae grayish-yellow tomentose; setae pro-thorax and coxae white, those meso- and katepisternum black, merals partly black, those below brownish white.
Wings: infuscated with gray cloud covering apical half subcostal cell, discal cell largely hyaline; macrotrichia on costal vein black, veins dark brown, anterior cross vein 3/11 lengthdiscal cell. Base and stem of halteres brown, knob yellow.
Legs: femora black; tibiae excepting apical one-sixth black, reddish brown; the tarsi reddish brown except fore tarsi yellowish and tarsal joints mid and hind legs black above; basal third of claws reddish brown, black apically; empodium brown, pulvilli straw white. Bristles black; femora with long white setae posteriorly, long white setae below on fore femora and brownish white setae below on other femora, basal third hind femora with long white setae anteriorly and short black setae apically; setae of tibiae black except those apical 1/3 and apical 1/4 mid tarsi of fore tibiae white anteriorly; tarsal bristles black; tarsal setae black except as follows: joints 1–5 fore tarsi with narrow crest of silvery white setae dorsally, parted on all joints; joints 1 and 2 mid tarsi white setae dorsally; fore tibiae and tarsi anteriorly, hind tibiae at apex and metatarsi posteriorly with usual short golden pile.
Abdomen: shining black, tergites 2–3 with posterior gray tomentose fasciae complete, narrowly interrupted on tergite 4, small spot of gray pollen posterior corner fifth tergite; brown pollinose dorsocentral areas anteriorly tergites 2–5; tergites 6–7 shining black. Setae laterally segment 1 long, straw white, dorsum, short, straw white; segment 2 with long brown setae laterally, subequal to those first segment, short brown pile dorsally fading into white posteriorly; segment 3 with black setae laterally shorter and not so dense as on preceding segments, and short black setae fading into brown dorsocentrally; short black setae dorsocentrally in two separate rows middle and apex tergites 5–7, most distinct on sixth tergite; setae of sternite 1–3 white, 4–6 black.
Genitalia: shining black with short black setae except those apex of cercus brown.
Holotype, male: Carbon County, Wyoming: Bottle Creek Campground, Sierra Madres Mtns., 6 July 1963 / R.J. Lavigne (deposited in USNM).
Paratypes, males: Carbon County, Wyoming: Bottle Creek Campground, Sierra Madres Mtns., 6 July 1963 / R.J. Lavigne (one specimen deposited in CAS and the other in the collection of the senior author).
This new species runs to couplet 19 in Wilcox & Martin’s (1936) key. It is easily differentiated from both C. glarealis Melander and C. pulcher Back by the presence of the infuscated cloud at the apex of the wings of the male C. martini. This species is named in honor of Dr. Charles Martin (deceased), eminent authority on the family Asilidae, whose patience and understanding in training beginning dipterists is greatly appreciated.
Distribution: CARBON: Bottle Creek Campground, Sierra Madres Mtns., 6 July 1963 (RJL).
Habitat: Douglas fir forest and sagebrush steppe shrub and grassland vegetation types.
Ethology: Nothing known.
Prey: None known.
