Wood, 2007: Boring in wood of limbs and small stumps. Rabaglia et al. 2006: Wood, (1977) states that this species is probably of South American origin, where it and similar species occur. It is also now found in Africa.
Wood (2007) distinguishes T. varulus from T. pandulus (Wood) by the smooth, shining surface between punctures on the lower declivity; and by the larger, more regularly placed denticles on the ventrolateral margin of the declivity from the suture to the lateral margins.

Wood (2007) distinguishes T. varians from T. lenis by the presence of dense micropunctures on the excavated area of the declivity; by the smaller, conical, acutely pointed major spine on the declivity; and by the obtusely elevated, less coarsely serrate ventrolateral margins of the declivity.

Rabaglia et al. 2006: This species is unique among Xyleborus north of Mexico. It is closely related to X. horridatus Wood, which occurs in Costa Rica to northern South America. Both species have a concave declivity with a series of denticles on interstriae 1.

Kirkendall and Faccoli, 2010: This species is native to north Asia, though it is now established in North America as well. It can be found in the temperate zone in Europe. It is xylomycetophagous in its feeding habits and breeds by means of inbreeding. This species is Oligophagous and its hosts are only from species in the Fagaceae family.

Wood, 2007: Unthrifty limbs 5-10 cm in diameter were attacked. The mature gallery system consisted of a mass of bifurcately branched and rebranched tunnels. The entire system was rather compact, with none of the short branches extending more than a few centimeters from the original entrance tunnel.

Beaver and Browne, 1978: Associated largely with Fagaceae, but also reported from Dipterocarpaceae and Euphorbiaceae. A single specimen was taken from a stem 4 cm diameter. The gallery system resembles that of X. mancus. Hulcr and Cognato, 2012: Gallery consists of a radial tunnel leading to a large and irregularly shaped brood chamber.

Beaver and Browne, 1978: Associated only with Eugenia spp. (Myrtaceae). Gallery system similar to that of X. andrewesi. Browne, 1961: This species is the only Malayan ambrosia beetle that is known with certainty to have a fixed host relationship with the family Myrtacaceae and all records of it are from species of Eugenia. The observed hosts have been dying or cut trees, varying in diameter from about 3-15 cm. The nest is of the typical form of the genus with a more or less radial unbranched entrance tunnel and one terminal, large, oblong or subrectangular brood chamber in the longitudinal plane.
