Genus Cephennococcus Jałoszyński

Cephennococcus Jałoszyński, 2011a: 6 . Type species: Cephennococcus kuchingensis Jałoszyński, 2011a (des. orig.).

Cephennococcus includes four species distributed in Malaysia (Pahang, Sarawak and Terengganu states). Adults are extremely small; those of nominal species measure 0.58–0.83 mm, and a female of an undescribed species found on Borneo was reported that measures merely 0.46 mm, being the smallest known scydmaenine beetle ( Jałoszyński 2011a).

Cephennococcus can be easily distinguished from all other Cephenniini by its very stout body form, antennae with a distinctly asymmetrical, sharply delimited dimerous club; a strongly convex, strongly transverse, semicircular pronotum, in all known species conspicuously densely punctate, lacking antebasal pits and groove, but with a pair of ovoid posterolateral vesicular structures inside the prothorax (visible in transparent mounts); prosternal process in ventral view relatively narrow but fully separating procoxae and ventrally protruding beyond their ventral margins, in lateral view the process is strongly bent posterad and its subtriangular apex directed ventroposterad; each elytron with one very shallow, vestigial and asetose basal fovea; mesoventral intercoxal process broad and flat; mesocoxal rests with posterior margins carinate; and a row of foveate punctures on metaventrite along anterior margin of each metacoxa.
