Temnothorax koreanus

A relatively rare species, little is known about the biology of .

Identification
Terayama and Onoyama (1999) - Total length of workers around 2-2.5 mm. Body yellowish brown to blackish brown. Antennae 11-segmented; scapes short, distinctly not reaching posterior margin of head in full-face view. Anterolateral corners of pronotum distinctly angled in dorsal view. Mesosoma rugose. Propodeal spines long, about 3 times as long as wide. Petiole with a reverse U-shaped node.

T. koreanus is easily distinguished from its Japanese congeners by the distinctly angulate pronotal humeri.

Distribution based on Regional Taxon Lists
Palaearctic Region: China, Democratic Peoples Republic of Korea, Japan, Republic of Korea.
