Abacetus alluaudi is a species of ground beetle in the subfamily Pterostichinae.[1] It was described by Tschitscherine in 1899.[1] A. alluaudi is found in Cote d'Ivoire, Africa.[2] A. alluaudi is a shiny black beetle, with an unusual upper jaw (mandible) which is more likely found in Caelostomus species.[2]

Taxonomy and Phylogeny

[edit]

A. alluaudi is named after the French entomologist Charles A. Alluaud who first collected the species.[2]

Description

[edit]

Colour and Markings

[edit]

A. alluaudi is a shiny black colour with iridescent wings.[2] The line of the junction between the prothorax and the wings and the associated lateral edges, have a reddish tinge.[2] The legs and mouth feelers are a dull yellow brown to red in colour.[2] The antenna are a dark reddish-brown.[2]

Head features

[edit]

Upper jaw is very slightly arched, similar to Celostomus species.[2] Head is of medium size and smooth with short frontal impressions.[2] Rear of the beetles head strongly diverges from the base.[2] Female beetles have convex and protruding eyes.[2] A. alluaudi has long antennae extending from the shoulders with a large first segment, which is at least as long as the next two combined.[2]

Distribution and Habitat

[edit]

The species was originally collected by Charles A. Alluaud from Assinie, Cote d'Ivoire, Africa.[2] No other locations are known.

Very little is known about the habitat of A. alluaud, however, based on the collection records, the species is predominately found in a tropical savanna climate (Aw).[3] Tropical savannas comprises grassland with isolated trees and shrubs and are generally found between tropical rainforest and desert biomes.[4]

Assinie is located in Ivory Coast
