Ancyridris Wheeler, 1935: 1. Type species (by monotypy): A. polyrhachioides Wheeler , 1935: 2 (Mt Misim, PAPUA NEW GUINEA). A. polyrhachioides Wheeler , 1935: 2, fig. 1, a-c; Mt. Misim, PAPUA NEW GUINEA. A. rupicapra (Stitz) , 1938: 99, fig. 1, a-d; 'DEUTSCH NEU-GUINEA' ( Pheidole (Pheidolacanthinus) (sic!) rupicapra ) (Combination: Bolton, 1995: 62). Ancyridris (Figs 19, 20) is the only putatively endemic ant genus known from New Guinea. It was provisionally cited as a junior synonym of Lordomyrma by Brown (1973: 178), but subsequently listed by him with generic status (Brown, 2000: 47). The suggested synonymy was not followed by Bolton (2003, et al.), and is declined here. Recent studies investigating DNA affinities among a number of myrmicine ants could indicate that the Ancyridris species comprise a sister group to the rump of Lordomyrma (Lucky, Sarnat & Ward pers.coms). Its species could, however, be considered a lineage within the Lordomyrma clade . The genus is singularly morphologically distinctive and surprisingly species-rich, yet its taxa are structurally only modestly interspecifically diversified. Ancyridris appears to be limited to elevations above about 1,500 m.

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

==Description== thumb|left|Ancyridris polyrhachioides|A. polyrhachioides worker:a) Lateral viewb) Head, dorsal viewc) Thorax and abdomen, dorsal view The eyes are well developed. 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.
