The Stenochiinae are a group of often metallic-coloured darkling beetles that are most diverse in tropical regions.

Characters (from Matthews & Bouchard 2008): Labrum transverse, tormae with mesal extremities not or only slightly expanded, epitorma present, setal pattern symmetrical. Eye reniform. Antennae with scattered complex stellate sensoria on last 5–7 segments. Mandibular mola with fine striations. Corpotentorium present, more or less flat, sometimes sinuate. Procoxal cavities internally closed. Mesocoxal cavities closed in part by mesepimera. Elytral striae nine plus scutellary striole, sometimes effaced. Wing with large radial cell, long RP, diffuse apical flecks, often no medial fleck, with vein CuA1 usually anastomosed with MP3+4 for greater or lesser distance producing characteristic X configuration, apical field about one-quarter of wing length, wings sometimes absent. Legs not fossorial. Claws simple. Metendosternite without laminae. Dorsal edge of last abdominal ventrite with angular inner edge, or simply rounded. Defensive reservoirs usually transversely annulated by thickening of cuticle, with ample common volume, not eversible, glands draining by a single or more ducts. Ovipositor nearly always greatly modified, with coxite lobe 1 elongate and its baculus longitudinal, paraproct baculi transverse and often articulating at their outer extremities with ends of additional sclerites which articulate in turn with proctigeral baculi. Female tract often without primary bursa, although secondary bursa occasionally present, with long filamentous accessory gland apically expanded into spherical or fusiform spermatheca, without vaginal sclerites. Aedeagus with tegmen usually dorsal or lateral (rotated 60° to 90°), with median lobe adnate to tegmen, with well-developed alae formed as extensions of apical piece.
