Belongs within: Tenebrionoidea. The Lymexylidae, timberworm beetles, are a group of elongate, soft-bodied insects that bore into hard wood. Species of Lymexylon and the subfamily Atractocerinae have the elytra shortened, exposing much or all of the abdomen, whereas the elytra more or less cover the abdomen in Hylecoetinae and Melittomminae. A distinct cervical constriction is… Continue reading Lymexylidae


Belongs within: Tenebrionoidea.Contains: Eletica, Derideini, Nemognathini, Meloinae. The Meloidae, blister beetles, are a group of soft-bodied beetles whose larvae are often parasitoids on bees. The vernacular name of the group refers to the production by adults of caustic defensive chemicals, cantharidins. The tarsal claws are typically subtended by a ventral blade that may occasionally be… Continue reading Meloidae


Associating with the Spanish fly Published 12 December 2023 The classification of the blister beetles has been subject to numerous revisions over the years, with the status of many subgroups remaining uncertain. Perhaps the most uncertainty of all has surrounded the representatives of the tribe Lyttini. As a tribe of the subfamily Meloinae, the Lyttini… Continue reading Lyttini

Belongs within: Tenebrionoidea. The Aderidae are a group of small, often colourful beetles typically found on vegetation, often resting on the undersides of leaves. Larvae have been collected in rotting wood, under bark or in leaf litter, or in insect nests (Chandler 2002). Characters (from Lawrence & Britton 1991): Elongate, convex to somewhat flattened beetles;… Continue reading Aderidae


Belongs within: Anthicidae. The Formicomini are a tribe of anthicid beetles united by having the mesepisterna simply connected with the mesepimera, their margins not raised and bare, a widely rounded to subtruncate and incompletely bordered intercoxal process on abdominal sternum III, and distinct posteriorly projecting prongs on the male sternite VIII (Kejval 2009). <==FormicominiK09 |–Andrahomanus… Continue reading Formicomini


Belongs within: Tenebrionoidea.Contains: Ripiphorinae. The Ripiphoridae are a group of beetles whose larvae are parasitoids of other insects. In members of the subfamily Ripiphorinae and male Ripidiinae, the elytra are more or less reduced and either apically dehiscent and acute or leave the hind wings largely exposed; in female Ripidiinae, both elytra and hind wings… Continue reading Ripiphoridae


Belongs within: Tenebrionoidea.Contains: Eurygeniini, Formicomini, Notoxus, Anthicus. The Anthicidae are a family of elongate, usually hairy beetles which have the back of the head constricted into a distinct ‘neck’. Most species are found in decaying vegetation or leaf litter, and are believed to be scavengers. A number of species of the subfamily Anthicinae are found… Continue reading Anthicidae
