Diagnosis
This species is divided into two subspecies, one of which is newly relegated to a subspecies of Lasioglossum subopacum as treated below. The nominotypical subspecies is separated from the ssp. okinawa by only the female characteristic that propodeum, and T1 basally with dense and thick yellowish tomentose as in Figs 20, 22. In male, both subspecies cannot clearly separate. This subspecies is separated from the other Korean Lasioglossum s. str. species in having the combination of following characters: the mesoscutum reflexed upward in both sexes and densely transversely rows on medio-anterior margin in female; the female propodeum and T1 with dense yellowish tomentose; the shape of hair tufts on male S6 and the gonostylus as in Fig. 11; and the male genitalia without ventral retrorse.
Distribution
China (north and southeastern areas), Taiwan, Vietnam, Philippines, and Korean Peninsula (south).
Flight record
Female: March to December. Male: May to October.
Flower record
In Korea, this species visited the following six species of flowering plants. Apiaceae: Angelica miqueliana. Asteraceae: Aster yomena; Sonchus arvensis. Brassicaceae: Brassica sp. Caprifoliaceae: Lonicera sp. Rosaceae: Crataegus sp.
