Halictus sulcatulus Cockerell 1925: 9 [Syntypes: U.S. National Museum of Natural History, Smithsonian Institution, Washington, D.C., USA and Museum für Naturkunde an der Humboldt Universität zu Berlin, Germany; ♀, type locality = Okeanskaya (near Vladivostok), Russia].
Lasioglossum (Evylaeus) sulcatulum: Ebmer 1982: 219 View in CoL , Photo 8 in Plate III; Ebmer 1985: 220; Ebmer 1996: 287. Evylaeus (Microhalictus) sulcatulus sulcatulus: Pesenko 2007b: 84 (in key), 93 (in key), 109, Figs 95–97 (♂).
Diagnosis. This species is similar to L. pumilum Sakagami & Tadauchi and L. zunaga Sakagami & Tadauchi from Japan. It is separated from L. pumilum by female metapostnotum with longer ridges reaching to near posterior margin and female T1 with distinct short hairs on medial to apical area; from L. zunaga by T1 basally with a pair of thin hair tufts in both sexes. In contrast, L. pumilum has female metapostnotum with shorter ridges reaching to anterior half and female T1 nearly smooth on medial to apical area; in L. zunaga , T1 smooth over entire surface in both sexes.
Lasioglossum sulcatulum is also divided into two subspecies (Ebmer 1996), the nominotypical subspecies ranging to the Russian Far East, and L. sulcatulum longifacies Sakagami & Tadauchi from Japan. According to Pesenko (2007b), the nominotypical subspecies is separated from L. sulcatulum longifacies by the female head as long as wide or slightly longer than wide (length/width ratio not more 1.5) and the female metapostnotum with longer ridges but not reaching posterior margin on medial area. In contrast, in the ssp. longifacies, the female head longer than wide (length/width ratio 1.07–1.15), and the female metapostnotum with shorter ridges occupying only on anterior half.
Distribution. South Korea, Russian Far East.
Flight period in South Korea. Both sexes: July.
