Tetramorium rimytyum Bolton

Type location Ghana (Bolton, 1980, illustrated, alitrunk and pedicel, worker). Solely known from the holotype described from his own collection at Mt. Atewa, where he found it on a fallen tree trunk (1.xii.1968) .

Bolton's description (1980) is at .

WORKER - TL 4.8 mm; clypeus with conspicuous median notch. Antennal scrobes absent. Eyes prominent and hemispherical in full-face view. Propodeum with long, narrow spines and conspicuous metapleural lobes. Petiole with fairly long peduncle and domed profile, postpetiole also domed but dome as if falling backwards. All dorsal surfaces with abundant long, fine, acute hairs. Colour uniform dark brown.

According to Bolton, this is of some significance as an intermediate between the aculeatum-group and the more obviously typical Tetramorium types of the setigerum-group. If, as seems the case, the specimen I separated out as Macromischoides species Tą was determined by Bolton as no more than one of the variants of Tetramorium aculeatum [he lists a finding as "Onipe (B. Taylor)")] then this species, based on a single specimen must be of questionable status.
