Description.
Female (Holotype) (Fig. 20). Body length ca 21.5 mm.
Head with GOI = 2.9 (Fig. 20C). Lower face 0.7 × as wide as high, rather finely punctate with setae, strongly shiny (Fig. 20B). Clypeus 1.3 × as wide as high, finely punctate with setae, moderately convex in profile, and its lower margin impressed (Fig. 20B, C). Malar space 0.4 × as long as basal mandibular width (Fig. 20B, C). Mandible weakly twisted by ca 20°, moderately long, evenly narrowed, its outer surface with a diagonal setose deep groove between its dorsoproximal corner to base of mandibular apical teeth (Fig. 20B, C). Upper mandibular tooth 1.6 × as long as lower one, slender and cylindrical (Fig. 20B). Frons, vertex and gena strongly shiny with fine setae (Fig. 20B-D). Posterior ocellus almost touching eye (Fig. 20B-D). Ventral end of occipital carina joining oral carina. Antenna with 64 flagellomeres; first flagellomere 1.7 × as long as second; 20th flagellomere 2.2 × as long as wide.
Mesosoma entirely strongly shiny with setae (Fig. 20E). Pronotum finely punctate dorsally and strigose to rugose ventrally (Fig. 20E). Mesoscutum 1.5 × as long as its maximum width, almost smooth with very fine punctures with setae, and evenly rounded in profile (Fig. 20E). Notauli absent (Fig. 20E). Scutellum moderately convex, anterior 0.4 transversely striate, anterior 0.4-0.5 punctate, and posterior 0.5 longitudinally strigose, with lateral longitudinal carinae reaching posterior end (Figs 2G, 20E). Epicnemium densely punctate with setae. Epicnemial carina present, evenly curved to anterior, its dorsal end close to anterior margin of mesopleuron (Fig. 20E). Mesopleuron entirely finely punctate, longitudinally strigose ventrally (Fig. 20E). Submetapleural carina weakly evenly broadened anteriorly (Fig. 20E). Metapleuron entirely finely punctate with setae (Fig. 20E). Propodeum almost evenly rounded in profile; anterior transverse carina complete; anterior area longitudinally striate; spiracular area almost smooth with very fine and sparse punctures with setae; posterior area rather finely irregularly rugose; propodeal spiracle elliptical, its outer margin not joining pleural carina by a ridge.
Wings. Fore wing length ca 13.5 mm with AI = 0.4, CI = 0.4, DI = 0.4, ICI = 0.5, SDI = 1.2, SI = 0.1, SRI = 0.3; vein 1m-cu&M weakly sinuous; vein 2r&RS almost straight and RS evenly curved; fenestra and sclerites of discosubmarginal cell as in Figure 20F; proximal sclerite triangular, confluent with distal sclerite, moderately pigmented; central sclerite rather small and its minor diameter smaller than thickness of vein 2r&RS, elliptical, moderately sclerotised and pigmented, positioned in mediodistal part of fenestra; distal sclerite moderately pigmented; proximal corner of marginal cell evenly setose; posterodistal corner of second discal cell ca 105°; posterodistal corner of subbasal cell ca 85°; vein 1cu-a subinterstitial to M&RS (Fig. 20F). Hind wing with NI = 1.3, RI = 1.7; vein RS straight; vein RA with 7 uniform hamuli.
Legs. Outer surface of fore tibia with sparse spines. Hind leg with coxa in profile 2.0 × as long as deep; basitarsus 2.0 × as long as second tarsomere; fourth tarsomere 0.6 × as long as third tarsomere and 4.6 × as long as wide; tarsal claw simply pectinate.
Metasoma with PI = 2.9, DMI = 1.4, THI = 2.9; dorsal margin of tergite 1 weakly sinuous; thyridium elongate (Fig. 20A).
Colour (Fig. 20). Entirely testaceous except for apex of mandible black. Wings hyaline; sclerites amber; veins brown.

Differential diagnosis.
Mandibular structure and mesosoma sculpture of E. phulchokiensis sp. nov. indicate that it belongs to the E. ramidulus complex. Enicospilus phulchokiensis sp. nov. runs to couplet 230 (including E. melanocarpus and E. xavius) of Gauld and Mitchell’s (1981: 143) key, and to couplet 61 (including E. melanocarpus and E. sauteri) of Tang’s (1990: 34, 181) key. However, E. phulchokiensis sp. nov. is distinguishable from E. melanocarpus, E. sauteri and E. xavius by the strongly sculptured scutellum (Fig. 2G), sinuous fore wing vein 1m-cu&M (Fig. 20F), and entirely testaceous metasoma without black posterior segments (Fig. 20A). Moreover, E. phulchokiensis sp. nov. is possibly related to E. puncticulatus Tang, 1990 and its related species-group, but distinguished from E. puncticulatus by the confluent proximal and distal sclerites (Fig. 20F) (separated in E. puncticulatus).
