This study describes the larva and pupa of the monotypic darkling beetle Idiobates castaneus (Knoch) (Coleoptera: Tenebrionidae) in the tribe Tenebrionini, from eastern North America. The species inhabits forested regions where adults and associated larvae have been discovered under dry loose bark of dead standing trees where cavities or pockets of frass have formed, apparently following infestations of other insects and rodents. Identity is confirmed by rearing of adults and pupae and preservation of associated exuvia. Distinctive characters of the larval abdominal apex and the armature of pupal ‘gin-traps’ are illustrated. A key to the larvae of North American genera currently placed in Tenebrionini is included.

The five species currently placed in the North American genus Haplandrus LeConte 1862 are examined, with new information on immature stages, distribution, and life history. The type-species, H. fulvipes (Herbst 1797) as a member of Stenochiinae/Cnodalonini is redescribed along with its larva and pupa; a closely related new species is proposed for specimens from peninsular Florida. Reassignments and new synonymies are proposed for the other species which belong in other genera and tribes of Tenebrioninae. Haplandrus ater (LeConte 1866) is transferred back to Metaclisa Jacquelin du Val 1861; H. collaris Casey 1924 and H. subangustus Casey 1924 are junior synonyms of that species. North American members of Metaclisa are reviewed, with a description of the larva and pupa of M. atra. Tharsus LeConte 1862 recognized as a new synonym of Metaclisa. With a discussion of morphology and placement of the genus, the new tribe Metaclisini is proposed. The new genus Bouchardandrus is proposed to include the boreal H. concolor LeConte 1866 which has characters that place it among genera of Tenebrionini.
