Cis boleti, copyright Francisco Welter-Schultes.

Belongs within: Tenebrionoidea.

The Ciidae are a group of beetles that mostly feed as both larvae and adults on basidiomycete fruiting bodies, though some may feed on rotting vegetation (Lawrence & Britton 1991). In most species (forming the subfamily Ciinae) the antenna has eight to ten segments and bears tufts of sensilla on each segment, but the Californian Sphindocis denticollis has eleven-segmented antennae lacking sensilla (Thayer & Lawrence 2002).

Characters (from Lawrence & Britton 1991): Elongate and subcylindrical or moderately flattened to ovate and globose beetles, subglabrous or clothed with decumbent and/or erect hairs or bristles. Head more or less deflexed, usually with distinct frontoclypeal ridge which may be produced in male to form a plate or paired tubercles or horns. Antenna with eight to ten segments, two- or three-segmented club large and loose with well-developed, multipronged sensoria; maxillae with reduced lobes and fusiform palps; pronotum large, sometimes with anterior plate or paired horns in male; fore coxae transverse or projecting, trochantin concealed; fore coxal cavities externally and internally open; mid coxal cavities contiguous, laterally open; tibiae almost always lacking spurs and with spines along outer edge; fore tibia often with acute tooth or comb of spines at apex; tarsi quadramerous; abdomen with five ventrites, all free, ventrite 1 often with setose fovea in male. Larvae elongate, subcylindrical, lightly sclerotised with variable armature (usually paired, hook-like urogomphi) on T9 and pygopod-like 10th segment. Antennae very short, with long sensorium arising from near base of terminal segment; mandible often with acute, hyaline process at base; maxilla with reduced, subapical lacinial lobe.
