Type material.

Holotype (FRI), paratype (NMNH, 1).

Diagnosis.

3.0 mm long (n = 1); 2.72 × as long as wide. This species is distinguished by the protibiae posterior faces inflated, granulate; antennal club wider than long; posterolateral carina costate; elytra truncate, surrounded by a circumdeclivital carina; boundary between elytral disc and declivity distinct, elytral disc without strial furrows and interstrial ridges; circumdeclivital carina emarginated at each striae (striae 5 and 6 may be weakly indicated); and declivital striae setose, setae minute, recumbent, as long as a strial puncture.

Distribution.

India (Andaman Is, Assam).

Host plants.

Recorded from two species of Dipterocarpus ( Dipterocarpaceae ) ( Maiti and Saha 2004).

Remarks.

This species is transferred to Arixyleborus from Amasa . This species displays a superficial morphological resemblance to Amasa , however it possesses the unique characteristics exhibited by Arixyleborus including protibiae slender, inflated and granulate on posterior faces, antennal club type 2, six striae present on the declivity, and pronotum from dorsal view elongated basic shape with rounded frontal margin (type 7).
