Euurobracon triplagiata ( Cameron, 1900)

( Figs 1B, 3A–3E)

Body length. 15.1 mm; forewing length= 14.8 mm; ovipositor sheath = 20.2 mm.

Diagnosis. Hind wing vein 2-SC+ R transverse; ovipositor less than 4.0× longer than the fore wing; inter-tentorial distance/tentorio-ocular distance>1.75 ( Figs 3A–3C). Apical third of forewing membrane with extensive grey or grey-brown pattern, and in particular second submarginal cell with at least its posterior half marked with grey or fuscous brown ( Fig. 3D). Antenna broken with only 36 intact flagellomeres, 1 st flagellomere 1.5 and 1.8× longer than the 2nd and 3rd flagellomere respectively, medial flagellomeres wider than long. Inter-tentorial distance: tentorio-ocular distance = 2:1. Frons antero-laterally setose, its medio longitudinal area with longitudinal groove/ sulcus bare, face rather impressed on either side of the triangular supra-clypeal area, the central and surrounding depressed areas smooth, shiny and glabrous, dorsal area below antennal sockets with long setae. Shortest distance between eyes: width of head = 1:2. Mesosoma smooth and shiny, propodeum sparsely setose medially and densely setose laterally; Length of forewing vein SR1: 3-SR:r = 67:46:11. Forewing vein m-cu straight, 2.7× longer than 2-SR+M, Length of vein 2-SR:3-SR:r-m = 32:67:35, 3-CU1 moderately to strongly expanded posteriorly. Hind wing vein 2- SC+ R and lr-m almost as long as SC+ R 1. First metasomal tergite 1.1× as long as its maximum width, with a mid-longitudinal depression, and having posteriorly raised broad median area; second metasomal tergite approximately 2× wider than long, without prominent pits on either side of midline ( Fig. 3E); ovipositor sheath 1.4× as long as fore wing.

Colour. Antenna and ovipositor sheath black, head brownish yellow, hind leg yellow except telotarsus, which is brownish yellow. Wings yellow basally brown apically; forewing with a usually complete yellow or yellow-hyaline cross band at level of basal half of the pterostigma ( Fig. 1B).

Variations. Metasomal tergite 4 with a baso-medial transverse area narrowing laterally, demarcated by a groove.

Material examined. 1♀ (regd. 26924/H3), INDIA, Madhya Pradesh, Pachmari, 28.iv.1975, coll. S.K Gupta and party.

Distribution: India (Madhya Pradesh, Meghalaya Tamil Nadu, Uttar Pradesh ( Beeson & Chatterjee, 1935; Cameron, 1900; Chatterjee & Misra, 1974; Enderlein, 1920; Quicke, 1989). Elsewhere: China, Nepal, Sri Lanka ( Li et al., 2016).
