Prenolepis (Nylanderia) longicornis (Latreille)

Stanleyville, [[worker]], [[queen]]; Zambi, [[worker]], [[queen]] (Lang and Chapin). Numerous specimens showing some variation in color. The forms with paler workers might be assigned to ForeFs variety hagemanni, originally described from Boma, in the Belgian Congo, but of the few distinguishing characters mentioned by the Swiss myrmecologist, the whiteness of the hairs is noticeable in all the longicornis workers I have seen from various parts of the world and the body color varies even in the same colony. These facts and a study of a cotype of hagemanni received from Prof. Forel convince me that the name should be relegated to the synonymy. Forel believed that his hagemanni might be the worker of Emery's P. waelbroecki , described from female and male specimens, but the females accompanying pale longicornis workers from Stanleyville and Zambi are the same as those accompanying darker workers from other localities in the East Indies and tropical America and do not agree with Emery's description of the waelbroecki female, which is larger, ferruginous instead of dark brown, more hairy, with a much broader head, larger eyes and shorter antennal scapes.
