( Fig. 35 )

Leptothorax congruus var. spinosior FOREL, 1901: 371 , workers, Japan, Sapporo; WHEELER, 1906: 317 (queens).

Leptothorax spinosior : TERAYAMA & Satoh, 1990: 532 [raised to species]; TERAYAMA et al., 1992: 28; BOLTON: 1995: 245; WU & WANG, 1995: 109; RADCHENKO, 1996: 16; KIM, 1996: 177; TERAYAMA & OGATA, 1999: 93; IMAI et al., 2003: 156; KIM, 2003: 2; LYU & CHO, 2003: 274.

Temnothorax spinosior : BOLTON, 2003: 271.

Material examined. 2 workers, syntypes (1 worker is damaged, without postpetiole and gaster),

“ L. congruus Sm. var. spinosior Forel , type, Sapporo , Japan ” ( MHNG).

Distribution. Japan, Korean Peninsula, NE China.

Ecology. It inhabits open dry grasslands; nests are built in soil ( TERAYAMA & ONOYAMA, 1999).

Notes. T. spinosior most resembles T. eburneipes (see Notes under the latter species). Among rich investigated material from North Korea (more than 100 specimens) I did not find T. spinosior , but T. eburneipes only; records of T. spinosior from South Korea and China need confirmation.
