A new species of Callomegachile from Larat, Indonesia (Hymenoptera: Megachilidae)

A new species of large Callomegachile Michener, subgenus Eumegachilana Michener (Megachilini), is described and figured from Larat Island, Indonesia. The new species is superficially most similar to Callomegachile (Eumegachilana) godeffroyi (Friese) from New Britain, Papua New Guinea owing to the orange to orangish setae of the propodeum and first metasomal tergum, but can be distinguished by the absence of such setae on the head and pleura, the form and sculpturing of the clypeus, the form of the labrum, and the smaller size. A key is provided to the subgenera of Callomegachile, with Oxymegachile subgen. n. established for C. duponti (Vachal).
