Adapted from Wood 1982, p. 991-1139


Pityophthorus are a large and difficult group; they are distinguished from Araptus Eichhoff in that they have chitinized lateral septa on their first two sutures.


Species in this genus range from 0.8 to 3.2 mm in length and are approximately 2.0 to 3.4 times as long as wide. Their color ranges from yellowish brown to almost black. The pronotum is equally to longer than wide, and the lateral margins present a raised line. The scutellum is large and flushed with the elytra. The declivity varies from convex to bisulcate and can be unarmed or bearing small granules. The metepisternum is only visible anteriorly. The frons is usually sexually dimorphic, often ornamented by long setae. The anterior margin of the compound eye is emarginate. The scape is usually approximately as long as the 5-segmented funicle. The club is near circular to oval, with two to three straight to procurved complete to incomplete sutures, which have some degree of septation. The procoxae are contiguous.
