Strumigenys anthocera

Identification
Bolton (2000) - A member of the Strumigenys tococae-group. Like Strumigenys usbensis and Strumigenys fairchildi, anthocera has the first gastral tergite finely and densely sculptured everywhere. S. anthocera is the largest of the three and is unique in the group in having a simple apicoscrobal hair and a pair of standing hairs on the mesonotum. The other species lack projecting hairs at these locations. Spongiform tissue is better developed on the waist segments in anthocera than in usbensis or fairchildi; usbensis lacks spongiform tissue beneath the petiole, which is distinct in anthocera and fairchildi though broader in the former than in the latter. The spongiform lobes of the waist segments tend to be narrow and sublamellate in fairchildi but are thick and coarse in anthocera.
