Metriorrhynchus

Belongs within: Lycinae. Metriorrhynchus is a genus of lycid beetles in which the prothorax, which covers the head, bears distinct areolets, and which have elytra with the subsutural costa parallel with the suture. A genus Porrostoma has historically been recognised for species in which the rostrum is rather long, thin and shining, but no clear division can… Continue reading Metriorrhynchus

Cantharidae

Belongs within: Elateroidea.Contains: Silis, Cantharinae. The Cantharidae are a group of soft-bodied beetles that are usually coloured in contrasting patterns of yellow and black, reflecting their production of distasteful defensive chemicals. Larvae are found in soil and leaf litter; most are predators though some are phytophagous (Lawrence & Britton 1991). Adults are commonly found on… Continue reading Cantharidae

Lampyridae

Belongs within: Elateroidea.Contains: Photuris, Lampyrini, Photinini. The Lampyridae, fireflies, are a group of soft-bodied beetles with luminous organs on the underside of the abdomen. Adult males fly shortly after dusk and flash the light organs to attract mates (Lawrence & Britton 1991). Larvae are predaceous and also luminescent, with larval luminescence perhaps having an aposematic… Continue reading Lampyridae

Elateridae

Belongs within: Elateroidea.Contains: Physodactylinae, Agrypninae, Denticollinae, Elaterinae, Thylacosterninae, Lissominae, Cardiophorinae, Negastriinae. The Elateridae are the click beetles, so called for their ability to jump by rapidly bending the thorax (producing a clicking noise). This clicking ability is enabled by a long prosternal process entering a cavity on the mesosternum, causing a build-up of potential energy… Continue reading Elateridae

Hemirhipini

Belongs within: Agrypninae. The Hemirhipini are a group of click beetles with scale-like setae and the medial margin of the hypomeron evenly margined (Johnson 2002). <==Hemirhipini [Chalcolepidiini]KB11 |–Calais speciosus (Linnaeus 1767)B14 |–Cryptaulus larvatus (Candèze 1874)KB11, PS07 [=Alaus larvatusPS07] |–Pherhimius Fleutiaux 1942J02 |–Tetrigus Candèze 1857PS07, C96 | |–*T. parallelus Candèze 1857C96 | |–T. australicus Blackburn 1896C96… Continue reading Hemirhipini

Agrypninae

Belongs within: Elateridae.Contains: Pseudotetralobus, Monocrepidiini, Agrypnini, Hemirhipini. The Agrypninae are a group of click beetles typically possessing one or two setae arising basally from the tarsal claws and/or lacking a wedge cell in the hind wing (Calder 1996). The Drilini, a derived tribe with males soft-bodied and females larviform with only the mouthparts and head… Continue reading Agrypninae

Conoderus

Belongs within: Monocrepidiini. Conoderus is a cosmopolitan genus of click beetles with the highest diversity of species in Australia and South America (Calder 1996). Characters (from Calder 1996): Frontal margin of head rounded and carinate between supra-antennal ridges; anterior margin of frons wide, almost perpendicular to plane of labrum; pronotum with uniform punctation; anterior section… Continue reading Conoderus

Monocrepidiini

Belongs within: Agrypninae.Contains: Conoderus. The Monocrepidiini are a diverse tribe of click beetles, diagnosed by their sharply carinate frons, usually lobed or broadened fourth tarsal segments, and eleven-segmented antennae (Stibick 1979). Representatives include the cosmopolitan genus Drasterius, distinguished by unicarinate pronotal hind angles and simple fourth tarsomeres (Calder 1996). Lacon is also cosmopolitan and has… Continue reading Monocrepidiini

Denticollinae

Belongs within: Elateridae.Contains: Hapatesus, Elatichrosis, Glypheus, Dicteniophorus, Drymelater, Neboisselater, Athous. The Denticollinae are a group of click beetles in which the head is typically more or less flattened in front, giving it a prognathous appearance. In the Pityobiini, sometimes treated as a distinct subfamily Pityobiinae, the frontoclypeal region is produced forward to partially cover the… Continue reading Denticollinae

Agrypnini

Belongs within: Agrypninae. The Agrypnini are a large group of click beetles distinguished by having deep grooves on the prosternal sutures that the antennae can lay in, and an undivided mesosternum and mesepisternum (Stibick 1979). The genera Lanelater and Agrypnus are each found worldwide except in South America. Species of Agrypnus have a vestiture of… Continue reading Agrypnini
