Dolichoderus sibiricus

This species nests in dead tree trunks or branches, and is distributed from the lowlands to mountainous regions (Japanese Ant Image Database). Idogawa and Dobata (2018) found colonies nesting in bamboo cavities in Kyoto Prefecture, Japan in a thicket dominated by deciduous broad-leaved trees. Alates fly from nests during August (Sonobe, 1984).

Distribution based on Regional Taxon Lists

Raised to species: Yasumatsu, 1962: 96. Senior synonym of abietis, japonicus, yoshiokae: Yasumatsu, 1941: 182; of atriceps, sinensis: Yasumatsu, 1962: 96.

Worker
Wheeler (1934) for Dolichoderus quadripunctatus yoshioke - Length 2.8-3 mm.

Smaller than sibiricus and of the same size as the typical quadripunctatus. The sculpture is like that of sibiricus, but the surface of the head and thorax is more shining, apparently because the cavities of the numerous pits, or foveolae are smoother and not so distinctly reticulate as in that subspecies. The color is different: Head, coxae and gaster black; the paired spots on the first and second gastric segments ivory white, very large and sharply defined; thorax and petiole deep red, with the extreme base of the epinotum and anterior portion of the metapleurae black; summit of petiolar node infuscated; mandibles, antennae and legs yellowish red; a spot on the distal enlargement of the scapes and the distal portion of the funiculi fuscous; femora and tibiae dark brown, except at their bases.

Type Material
Described from ten workers taken by Mr. H. Yoshioka at Kiryu, Japan, Nov. 26, 1932.
