Diplura

Belongs within: Panhexapoda.
Contains: Campodeoidea, Japygidae.

The Diplura are a cosmopolitan group of slender-bodied, wingless, blind hexapods that are mostly found in damp soil under logs and stones (Condé & Pagés 1991).

Characters (from Condé & Pagés 1991): Small to large, narrow-bodied hexapods, mostly unpigmented; eyes absent; antennae moniliform, with intrinsic muscles in the flagellar segments; thorax usually weakly developed; legs 5-segmented; abdomen 10-segmented, with styles and exsertile vesicles on at least some of the segments, gonopore between 8 and 9; cerci variously developed. Larval development epimorphic.
