Carebara vidua F. Smith ^HNS

Niangara, [[queen]]; Faradje, [[queen]] (Lang and Chapin); Yakuluku, [[male]] (J. Rodhain). The specimens from Niangara have the gaster black and therefore belong to the variety dux of Forel; one specimen from Faradje has the gaster castaneous and is therefore transitional to Santschii variety abdominalis. Arnold has shown that these color differences are merely nest variations, so that they may be relegated to the synonymy of vidua ^HNS.
