Baracidris View in CoL HNS Bolton (Figs. 69, 70, 77)
Baracidris HNS Bolton, 1981:252 (w). Type species: Baracidris meketra Bolton HNS (by original designation). Bolton, 1995:22.
The genus Baracidris HNS includes three small species (one undescribed) which are litter inhabitants in Central and Western Africa. Although the genus is easily isolated from the other African myrmicines, this is a more difficult task regarding the World fauna. The combination of characters (median portion of the clypeus as narrow fringe, antennae 12 segmented with club 2 segmented, reduced palps, metapleural lobes larger than in Adelomyrmex HNS , petiole and postpetiole subcylindric) separates this genus from all other myrmicines, although currently we lack synapomorphic features for Baracidris HNS . We maintain this genus primarily upon its geographical distribution.
