Type species

Procryphalus populi Hopkins

Adapted from Wood 1982, p. 859-860


Procryphalus are distinguished from other North American Cryphalina by the combination of the rounded lateral margins of the pronotum and the oval club with 2 to 3 procurved sutures, the first being septate.


This endemic genus to North America north of Mexico has two species that range from 1.5 to 2.2 mm in length, and are approximately 2.5 to 2.8 times as long as wide. Their color ranges from dark brown to black. The pronotum is as long as wide with the lateral margins rounded, the anterior half is asperate and armed in its margin by several teeth. The scutellum is small. The declivity is convex and unarmed. The contrastingly light vestiture consists of recumbent, short, scale-like setae and short, erect, interstrial bristles. The anterior margin of the compound eye is entire. The scape is usually as long as the 4-segmented funicle. The club is elongate-oval, with two to three procurved sutures, the first septate. The procoxae are contiguous.
