Distribution. China. Thailand. Vietnam: Lao Cai *, Vinh Phuc, Hanoi, Bac Giang *, Hoa Binh, Phu Yen *, Lam Dong *.

Occurrence in Vietnam. March, May, June, September to November.

Remarks. Based on the black metasomal color, this species is more likely to be matched with Si. ansula , rather than Si. hong Lelej, 1995 , but there are likely to be additional undescribed males in Vietnam and the genus limits of the Oriental Smicromyrmini are difficult to ascertain, especially in males of Andreimyrme , Ephucilla , and Sinotilla .
