Type material.

Holotype (NHMW).

New records.

India: Assam-Arunachal Pradesh border: Bhalukpong, 27°00'48"N, 92°39'08"E, 150 m, 1-8.v.2012, L. Dembický, ex FIT (ZFMK, 1).

Diagnosis.

1.8-2.3 mm long (mean = 2.05 mm; n = 2); 2.09-2.25 × as long as wide. This species is distinguished by its small size; elytral disc gradually curving toward declivity, elytra rounded; posterolateral margins of elytra carinate to interstriae 7; declivital face with six punctate and clearly impressed striae; declivital interstriae granulate, uniseriate with erect hair-like setae longer 1-1.5 × the width of an interstria; pronotum 1.1 × long as wide, pronotum from dorsal view rounded (type 1) and lateral view basic (type 0), summit at midpoint, basal 1/2 smooth, shiny, sparsely minutely punctate; and sparse mycangial tuft on the pronotal base.

This species is very similar to X. germanus and is most easily distinguished by the larger, deeper strial punctures and clearly impressed striae.
