Diagnosis.

2.3-2.8 mm long (mean = 2.48 mm; n = 5); 2.3-3.13 × as long as wide. This species is distinguished by the posterior margin of elytra broadly rounded; declivital face with interstriae 1 and 2 unarmed by tubercles; declivital face weakly sulcate; large body size; lateral declivital margins elevated along interstriae 3, bearing two or three pairs of large, broad, obtusely pointed tubercles of different sizes on basal 1/2 of declivity; sulcate area of declivity smooth, shiny or opalescent; and stout body.

Similar species.

Xyleborinus echinopterus , X. ephialtodes , X. octiesdentatus , X. schaufussi , X. speciosus , X. spinipennis .

Distribution.

Recorded in the study region from Bangladesh, Cambodia*, China (Chongqing, Fujian, Guangdong, Guangxi, Hainan, Hong Kong*, Shanghai, Yunnan, unknown province), India (Madhya Pradesh, Sikkim, Uttarakhand, West Bengal), Laos, Myanmar, Taiwan, Thailand, Vietnam. It also occurs in Sri Lanka, and through the Indomalayan region to New Guinea and Australia and has been introduced to the United States ( Cognato et al. 2013; Gomez et al. 2018a).

Host plants.

Polyphagous ( Wood and Bright 1992).

Remarks.

In this species the gallery system is branched with several small brood chambers ( Browne 1961b).

The holotype of Xyelborus angustior is in poor condition; only the mesonotum and abdomen without elytra remain glued to the card. Eggers’ description clearly indicates that the specimen strongly resembled X. artestriatus before it became damaged. The species description and paratype specimen of Xyleborus undatus was also examined and found to be conspecific with X. artestriatus . Both species are here placed in synonymy with X. artestriatus .
