Leptothorax oceanicus
(Kuznetsov-Ugamsky, 1928)

This species inhabits mainly deciduous forests, but also it was found in meadows near lake shores, nests are built mostly in fallen logs, tree stumps, rarely in soil (Radchenko 2004).


Radchenko (2004) - L. oceanicus most resembles Leptothorax muscorum but differs from it mainly by the sharply triangular petiolar node with a very narrowly rounded dorsum, (in L. muscorum the petiolar node has a distinct, often rounded, dorsal plate) (for details see Radchenko & Heinze 1987).


Radchenko (2004) - L. oceanicus seems to be a quite rare species and is known from several localities between 41–53° N and 125–135°E: Russia: Amursky Region, Zeya; Habarovsk; Primorsky Region: Vladivostok; Anisimovka; Borisovskoe plateau; Suputinsky Natural Reserve; North-East China: Jilin Province; North Korea: Ryanggang Province.
