Species recognition. This is one of only two orange- or red-marked species (excluding legs) that occur in the extreme southern portion of the area covered by our key (reddish forms of other species occur only in the southeastern U.S.). The other species is Parancistrocerus histrio, which possesses an acarinarium at the base of tergum 2 (for further diagnostic characters see key).

Variation. Fore wing length 5.5–7.0 mm (♂♂), 6.5–7.5 mm (♀♀). Variation otherwise not studied.

Distribution. Not recorded from Canada. Mainly southeastern U.S.: NC, SC and FL (Krombein 1979); newly recorded from VA (1 ♀, Norfolk, DEBU).

Biology. Nests in borings in wood and uses firmly agglutinated sand for closing plugs and nest partitions. Caterpillars of Tortricidae and Gelechiidae serve as prey (Krombein 1967, 1979).
