Enicospilus (Unicorniata) enicospilus Nikam, 1972: 193 ; holotype ♀ from India ( MUC).

Enicospilus enicospilus – Nikam 1980: 166.

Diagnosis

Interocellar area reddish brown; clypeus flat to weakly convex, ventral margin blunt; mandible twisted 15–20°, outer surface without a diagonal setose groove; fore wing fenestra with proximal and distal sclerites present, distal sclerite weak, not joining proximal sclerite; metapleuron strigose.

Material examined

VIETNAM • 1 ♀; Hoa Binh Province, Yen Thuy, Lac Thinh ; 20–30 Sep. 2002; Khuat D.L. leg.; Malaise trap; IEBR • 1 ♀; Vinh Phuc Province, Tam Dao NP ; 2 Jul. 2003; Hoang V.T. leg.; light trap; IEBR • 1 ♂; Gia Lai Province, Kon Chu Rang NP ; 27 May 2019; Nguyen V.T. leg.; light trap; IEBR • 1 ♀; Lao Cai Province, Bat Xat NR ; 22°37′37″ N, 103°37′32″ E; 1840 m a.s.l.; 28 May 2022; Pham T.N. and Dang T.H. leg.; light trap; IEBR .

Remarks

In comparison with specimens examined by Gauld & Mitchell (1981), Vietnamese specimens have slightly broader lower face (0.75–0.82 × as wide as long vs 0.72–0.74×); fore wing index ICI varies from 0.7–0.85 (vs 0.65–0.7), AI = 0.59–0.76 (vs 0.78–1.1) and SDI = 1.22 (vs 1.3–1.35).

Distribution

Previously known from China, India, and Sri Lanka ( Yu et al. 2016). These are the first records of this species from Vietnam.
