Lasioglossum ( Evylaeus) ohei Hirashima & Sakagami View in CoL in Sakagami et al., 1966: 679 ( holotype: ELKU, ♀, type locality =Misano, Kitami City, Kitami Province, Hokkaido).

Diagnosis

Females are similar to L. ( H.) simplicior but separated from them by the head slightly longer than wide or nearly as long as wide (HL/ HW ratio 1.01 ±0.02), IS of mesoscutum nearly smooth on posterior margin, and metasomal terga with silky dull luster. In contrast, in L. ( H.) simplicior , the head wider than long (HL/ HW ratio 0.97 ± 0.03), IS of mesoscutum with distinct tessellation over entire surface, and metasomal terga with enamel-like luster as in most species of Lasioglossum .
