Ambrosiodmus obliquus
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.

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.

Wood, 2007: This species is xylomycetophagous, domicile parasites of other ambrosia beetles. The critical factor in host beetle selection appears to be the diameter of the entrance hole of the host beetle tunnel. After the host beetle has established its tunnel in small diameter stems (about 3-8 cm in diameter), this species arrives and force entry (apparently using the large prothoracic spines), and evicts the original tenants, eggs, larvae and boring dust. It then produces its own brood in that appropriated tunnel. Wood, 1982: Sampsonius spp. are ambrosia beetles. As with other Xyleborini, the males are flightless; therefore mating must occur in the brood chamber. The females are evidently incapable of excavating an entrance tunnel. They seek out a newly constructed tunnel of a Xyleborus species of appropriate diameter to accommodate their body and enter and often wait for the host to advance the tunnel adequately before clearing first one branch and then the other of eggs and young larvae; then they finally evict the host. Whether the host is removed forcibly or is repelled by offensive secretions or other factors was not determined. The Sampsonius female then deposits clusters of eggs in the tunnels. The larvae excavate tabular extensions of the gallery with the grain of the wood in much the same fashion as does the host species. They are found in branches or seedlings about 2-8 cm in diameter; they are very rare.The scolytid host species apparently was Dryocetoides capucinus.

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.
