The Opatrini are a tribe of tenebrionid beetles found in arid and sandy regions of Africa, southern Asia and Australia (Matthews & Bouchard 2008).

Characters (from Matthews & Bouchard 2008): Oblong-oval, moderately to strongly convex, fuscous or piceous. Total length 4–11 mm. Antennae not clavate, slightly and gradually expanded distally, with simple setiform sensilla only. Edge of clypeus deeply excised in middle. Labrum subquadrate, tormal arms with mesal extremities bent into both anterior and posterior extensions, setal pattern symmetrical, epitorma absent. Lacinia with uncus or stout bristle. Mandibular mola without fine striations. Eyes reniform or completely divided. Corpotentorium present, not arched. Procoxal cavities internally closed. Mesocoxal cavities partly closed by mesepimera. Elytra striate, with incomplete epipleura. Metendosternite with laminae except in flightless genera. Legs fossorial, usually with expanded and more or less toothed protibiae. Plantar surfaces bristled. Abdomen with defensive gland reservoirs long with constricted openings, without common volume, without reinforcing sclerites or prongs. Ovipositor relatively unmodified , with paraproct baculi longitudinal, coxite baculi transverse, coxite lobation complete and gonostyles free, or greatly shortened with paraproct baculi transverse, paraprocts sometimes rotated distad and partially enveloping coxite bases, coxite baculi oblique, coxite lobes fused, and gonostyles vestigial or absent. Female tract with single coiled bursa-derived spermatheca and filiform accessory gland, or with apparently primary bursa copulatrix and without spermatheca. Aedeagus with paramere-like clavae attached to apical piece distally and separated from it by complete suture, or partial suture, or completely or almost completely fused with apical piece.
