A revision of the ant genus Stenamma in the Palaearctic and Oriental regions (Hymenoptera: Formicidae: Myrmicinae)

Palaearctic and Oriental species of the myrmicine ant genus Stenamma Westwood are reviewed and keys are presented for their identification. Twenty four species are recognized from these regions. Three species are described as new (S. orientale from Sarawak, S. gurkhalis from Nepal, and S. jeriorum from Pakistan); the synonymy of four species is confirmed (S. tscherssicum = S. striatulum, S. westwoodii polonicum = S. debile, S. myops = S. punctiventre, and S. caucasicum = S. hirtulum = S. lippulum). Additional synonymies are presented (S. africanum submuticum = S. africanum = S, msilanum, S. golosojevi = S. ucrainicum = S, debile). Specimens representing types of two species have been lost (previous descriptions prove inadequate for identification) and the names associated should be considered Incertae Sedis until such specimens are located (S. westwoodii asiatica, and S. berendti).
