This is a rather small, coarsely punctate species, black with the middle and hind legs largely red. The pubescence is not as abundant as in haemato- poda and rhodopus.
Female: Inner margins of eyes converging below; under side of flagellum dusky; punctation of head coarse and close, cheeks more finely punctate than rest of head; clypeus with apical truncation bounded by more distinct angles than in haematopoda or rhodopus, truncation nearly as broad as distance from end of truncation to lateral angle of clypeus; distance from first to third mandibular tooth less than width of eye or length of last three antennal segments; anterior ocellus posterior to midpoint between bases of antennae and posterior edge of vertex. Scutum with punctures similar to those of vertex but more widely separated; scutum with distinct band of pubescence around it, so that there are no separate spots of pubescence anteriorly; punc- tures of mesepisterna finer than those of scutum; tegulae testaceous; middle femora and hind femora and tibiae red, fore femora, middle tibiae, and hind metatarsi sometimes reddish in part; inner margin of inner hind tibial spurs with fourteen small teeth, outer margin with about nine large teeth; inner margin of outer spurs with about five large, oblique teeth, outer margin with about seven oblique teeth. Abdomen quite coarsely punctate; posterior mar- gins of tergites reddish. Length 5V2 to 6? mm.
Male: Similar to female. Anterior margin of clypeus with conlcavity over half as long as basal width of clypeus and demarked by distinct angles; tarsi reddish; inner margin of inner hind tibial spurs with about twelve teeth, outer margin with about eight teeth; lateral teeth of sixth tergite short and acutely pointed, median teeth rather translucent, about as wide as long, rounded, concavity between them wider than a semi-circle. Length 4V2 to 5v2mm.
