Ancyridris

Ancyridris is a small genus of myrmicine ants, with only two described species from New Guinea.

The long and narrow mesosoma is shaped somewhat as in Aphaenogaster. The propodeum bears two long, flattened, hooked spines resembling those of Polyrhachis bihamata. On the pronotum there are long hairs. The worker of A. polyrhachioides is almost 6 mm long. Apart from the curious anchor-like spines on its propodeum, Ancyridris bears a general resemblance to Aphaenogaster or certain worker forms of Pheidole. Wheeler suspected some aberrant or archaic group, "another of the living fossils which are continually turning up in the Papuan and Australian Regions". Ancyridris in fact seems close to Lordomyrma. It is the only ant genus currently thought to be endemic to the island of New Guinea.
