Bothroponera pachyderma (Emery)HNS

Manamana, [[worker]]; Bafwasende, [[worker]]; Medje, [[worker]]; Ngayu. [[worker]]; Niapu, [[worker]], [[queen]]; Niangara, [[worker]]; Akenge, [[worker]], [[queen]] (Lang and Chapin). The specimens from Manamana, fourteen in number, are accompanied by the note: "Found under a log. When it was lifted the ants feigned death." The specimen from Bafwasende is very small. The specimens from the other localities, seventy-four in number, were all taken from the stomachs of toads (Bufo polycercus, superciliaris, funereus, and luberosus). One specimen from Akenge was taken from the stomach of a frog (Rana albolabris).

I believe I have identified this species correctly. All the specimens, both workers and females, have a blood-red, subtriangular spot at the middle of the posterior border of each gastric segment. I regard Santschii B. sculpturataHNS, described from a female, as synonymous with Emery's pachydermaHNS.
