Belongs within: Coleopterida.Contains: Adephaga, Archostemata, Myxophaga, Scirtoidea, Staphylinoidea, Hydrophiloidea, Scarabaeoidea, Elateriformia, Bostrichoidea, Coccinelloidea, Tenebrionoidea, Cleroidea, Cucujoidea, Phytophaga. The Coleoptera, beetles, are one of the most diverse groups of insects with over 300,000 species. The earliest beetles were probably inhabitants of subcortical and interstitial spaces in wood (Kirejtshuk & Nel 2013) but they have since diversified… Continue reading Coleoptera


Belongs within: Coleoptera. The Myxophaga are a group of small, algae-feeding, aquatic or semi-aquatic beetles. Adults respire via a plastron of air trapped by a dense pile of hydrophobic hairs, and contain the wings beneath the elytra by a rolling mechanism. Larvae, where known, possess tracheal gills and pupate within the last larval exuvium. The… Continue reading Myxophaga

Belongs within: Coleoptera. The Archostemata are a distinctive group of wood-boring beetles with the labrum fused to the head capsule in adults, and a distinctive wing-tucking mechanism where the wing tips are rolled rather than folded under the elytra (Grimaldi & Engel 2005). The most widespread family in the modern fauna is the Cupedidae, members… Continue reading Archostemata


Belongs within: Staphylinoidea.Contains: Acrotrichinae. The Ptiliidae, featherwing beetles, are a group of very small beetles with narrow hindwings bearing long marginal hairs, believed to be adapted for passive flotation. Historically, forms with elytra more or less complete have been recognised as the subfamily Ptiliinae, but phylogenetic analysis resolves such a grouping as non-monophyletic. Ant-associated species… Continue reading Ptiliidae

Belongs within: Meloinae. American hitch-hikers Published 11 June 2024 One of the major sticking points in the classification of the Meloidae, the blister beetles, has been the question of what to make of the Tetraonycini. This distinctive assemblage of blister beetles is unique to the Americas, and exhibits a number of features that stand out… Continue reading Tetraonycini


Belongs within: Staphylinidae. The Scaphidiinae are a group of rove beetles with a convex body form and long elytra covering most of the abdomen. As far as is known, all species are mycophagous (Newton et al. 2001). Characters (from Newton et al. 2001): Body form broadly oval, compact, very convex and shiny, with long slender… Continue reading Scaphidiinae


Belongs within: Staphylinidae.Contains: Termitonannini, Termitopaediini, Termitodiscini, Termitusina, Termitohospitina, Trichopseniini, Corotocini, Hypocyphtini, Aleocharini, Bolitocharini, Gyrophaenina, Homalota, Leptusina, Liparocephalini, Oxypodini, Falagriini, Geostibini, Doryloxenus, Lomechusini, Athetini. The Aleocharinae are a diverse group of staphylinid beetles in which the antennae are usually inserted in the vertex between the eyes (Newton et al. 2001). Characters (from Newton et al. 2001):… Continue reading Aleocharinae


Belongs within: Staphylinidae.Contains: Conosoma, Tachyporus. The Tachyporinae are an assemblage of staphylinid beetles lacking a distinct neck and with an epipleural keel on each elytron (Newton et al. 2001). Characters (from Newton et al. 2001): Body usually more or less sublimuloid, small head more or less retractile to level of eyes and lacking distinct neck,… Continue reading Tachyporinae


Belongs within: Staphylinidae.Contains: Coryphiina. The Omaliinae are a group of staphylinid beetles typically possessing a pair of ocelli near the hind margin of the head (Newton et al. 2001). The subfamily as historically recognised is resolved by molecular data as paraphyletic to taxa that have been assigned to separate subfamilies Glypholomatinae, Microsilpha and Empelus (Lü… Continue reading Omaliinae

Belongs within: Staphylinoidea.Contains: Pseudopsinae, Scaphidiinae, Osoriini, Piestinae, Oxytelinae, Proteininae, Omaliinae, Paederinae, Staphylininae, Mycetoporini, Phloeocharinae, Silphidae, Tachyporinae, Scydmaeninae, Aleocharinae, Steninae, Euaesthetinae, Leptotyphlinae, Pselaphinae, Leptochirini, Thoracophorini. The Staphylinidae is an extremely large family of usually small, gracile beetles with a flexible abdomen. Many staphylinids have reduced elytra that expose the greater part of a long, flexible abdomen,… Continue reading Staphylinidae
