Description.
Female (Holotype) (Fig. 19 View Figure 19 ). Body length ca 23.0 mm.
Head with GOI = 2.9 (Fig. 19C View Figure 19 ). Lower face 0.6 × as wide as high, shiny, rather finely punctate with setae (Fig. 19B View Figure 19 ). Clypeus 1.6 × as wide as high, sparsely and finely punctate with setae, almost flat in profile, and its lower margin acute (Fig. 19B, C View Figure 19 ). Malar space 0.2 × as long as basal mandibular width (Fig. 19B, C View Figure 19 ). Mandible weakly twisted by ca 25°, long, proximally strongly narrowed, centrally to apically subparallel sided, its outer surface flat and smooth without a diagonal groove and line of punctures (Fig. 19B, C View Figure 19 ). Upper mandibular tooth 1.3 × as long as lower one (Fig. 19B View Figure 19 ). Frons, vertex and gena moderately shiny with fine setae (Fig. 19B-D View Figure 19 ). Posterior ocellus almost touching eye (Fig. 19B-D View Figure 19 ). Ventral end of occipital carina joining oral carina. Antenna with 59 flagellomeres; first flagellomere 1.9 × as long as second; 20th flagellomere 1.5 × as long as wide.
Mesosoma entirely moderately shiny with setae (Fig. 19E View Figure 19 ). Pronotum finely coriaceous with punctures to closely strigose (Fig. 19E View Figure 19 ). Mesoscutum 1.5 × as long as its maximum width, finely punctate with setae, strongly shiny, and evenly rounded in profile (Fig. 19E View Figure 19 ). Notauli absent (Fig. 19E View Figure 19 ). Scutellum moderately convex, with lateral longitudinal carinae almost reaching posterior end, and moderately punctate with setae (Fig. 19E View Figure 19 ). Epicnemium densely punctate with setae. Epicnemial carina present, evenly weakly curved to anterior, its dorsal end not reaching anterior margin of mesopleuron (Fig. 19E View Figure 19 ). Mesopleuron entirely moderately punctate, and ventral margin longitudinally finely strigose (Fig. 19E View Figure 19 ). Submetapleural carina broadened anteriorly (Fig. 19E View Figure 19 ). Metapleuron diagonally closely strigose (Fig. 19E View Figure 19 ). Propodeum declivous in profile; anterior transverse carina complete centrally, its lateral end not joining pleural carina; pleural carina absent posteriorly; anterior area longitudinally striate medially and smooth laterally; spiracular area finely coriaceous; posterior area concentrically striate; propodeal spiracle elliptical, its outer margin not joining pleural carina by a ridge (Fig. 19E View Figure 19 ).
Wings. Fore wing length ca 15.0 mm with AI = 0.5, CI = 0.6, DI = 0.3, ICI = 0.8, SDI = 1.5, SI = 0.1, SRI = 0.3; vein 1m-cu&M moderately sinuous; vein 2r&RS very slightly bowed but almost straight, and RS evenly curved; fenestra and sclerites of discosubmarginal cell as in Figure 19F View Figure 19 ; proximal sclerite linear, weakly pigmented and virtually unsclerotised so that vestigial, separated from distal sclerite; central sclerite absent; distal sclerite almost absent but anterodistal part slightly pigmented; proximal corner of marginal cell uniformly setose; posterodistal corner of second discal cell ca 90°; posterodistal corner of subbasal cell ca 65°; vein 1cu-a antefurcal to M&RS by 0.2 × 1cu-a length (Fig. 19F View Figure 19 ). Hind wing with NI = 2.6, RI = 1.7; vein RS straight; vein RA with 11 uniform hamuli.
Legs. Outer surface of fore tibia with very few spines. Hind leg with coxa in profile 1.7 × as long as deep; basitarsus 2.2 × as long as second tarsomere; fourth tarsomere 0.6 × as long as third tarsomere and 2.6 × as long as wide; tarsal claw simply pectinate except lacking pecten proximally.
Metasoma with PI = 3.2, DMI = 1.3, THI = 2.5; dorsal margin of tergite 1 not sinuous; thyridium elongate (Fig. 19A View Figure 19 ).
Colour (Fig. 19 View Figure 19 ). Entirely testaceous except for apex of mandible black. Wings hyaline; sclerites of fore wing fenestra very slightly pigmented, testaceous; veins black to testaceous.

Differential diagnosis.
Enicospilus nikami sp. nov. is similar to E. biharensis , E. maruyamanus , E. pudibundae , and E. transversus and these species are rather difficult to separate from each other. However, E. nikami sp. nov. can be distinguished from E. biharensis , E. maruyamanus and E. transversus by the proximally incomplete pectinae of hind tarsal claw (Fig. 2J View Figure 2 ) (hind tarsal claw completely pectinate from its base to apex in E. biharensis , E. maruyamanus and E. transversus , as in e.g. Figure 2I View Figure 2 ), from E. biharensis and E. pudibundae by the sinuous fore wing vein 1m-cu&M (Fig. 19F View Figure 19 ) (1m-cu&M evenly curved in E. biharensis and E. pudibundae as in Figures 6F View Figure 6 , 23F View Figure 23 ), from E. maruyamanus by the entirely moderately punctate mesopleuron (Fig. 19E View Figure 19 ) (mesopleuron entirely longitudinally punctostriate in E. maruyamanus ) and the angle of posterodistal corner of second discal cell (i.e. ca 90° in E. nikami sp. nov. as in Figure 19F View Figure 19 , but ca 115° in E. maruyamanus ), and from E. transversus by the entirely moderately punctate mesopleuron (Fig. 19E View Figure 19 ) (mesopleuron entirely longitudinally striate in E. transversus ).
