Diagnosis Interocellar area black; lower face about 0.84 × as wide as long; clypeus convex, ventral margin acute; mandible wide and long, not at all narrow proximally, twisted ca 10°, outer surface without a diagonal setose groove; fore wing fenestra with proximal, central and distal sclerites, SDI = 1.0; metasomal tergites exceptionally long and narrow. Material examined VIETNAM • 1 ♀ ; Gia Lai Province , Kon Ka Kinh NP ; 1060 m a.s.l. ; 22 Feb. 2012 ; Hoang V.T. leg.; light trap ; IEBR • 1 ♀ ; Lai Chau Province , Sin Ho , Sa De Phin ; 22°18′18″ N , 103°13′37″ E ; 1760 m a.s.l. ; 31 May 2022 ; Pham T.N. and Dang T.H. leg.; light trap ; IEBR . Remarks Fore wing lengths of the two Vietnamese specimens are 16.7 mm and 13.5 mm ; the holotype from India has a fore wing of 15.0 mm. The female specimen from Gia Lai Province has greater fore wing indices as follows: AI = 1.29, CI = 0.72 and ICI = 0.42 (vs 1.15, 0.46 and 0.38, respectively in the holotype ). Fig. 31.
