Taxonomy

Ancipitis Hulcr and Cognato, 2013: 41.

Diagnosis

1.9−5.4 mm long, 2.08−2.73 times as long as wide. Ancipitis is distinguished by the unique submentum among xyleborines which is flat, flush with genae, and shaped as a distinct large triangle. Ancipitis can further be recognized by the elytra extremely long, flattened, very gradually descending, broadened laterally and elongated apically, the face appearing somewhat depressed below posterolateral costa and covered with hair-like setae; pronotum extended anteriad, appearing conical, without serrations on anterior margin; antennal club flattened, type 3 with 3 sutures visible on the posterior face; scape long and slender; protibiae slender, and all tibia bear large denticles; and procoxae appearing tall, longer than basal width. In addition, the scutellum is flat, flush with elytra, the procoxae are narrowly separated, mycangial tufts are absent, and elytra unarmed.

Distribution

temperate and tropical Asia and Melanesia

Gallery system

This consists of branched tunnels without brood chambers (Browne 1961b). There may also be surface galleries between the bark and the sapwood (Kalshoven 1959b, Browne 1961b).
