Enicospilus tangi Shimizu sp. nov. Figs 2B, H View Figure 2 , 25 View Figure 25
Etymology.
The specific name is dedicated to Dr Yuqing Tang who described E. longitarsis , which is morphologically the most similar species to the one that is hereby described, and has contributed to the taxonomy of Ophioninae in Asia, represented by the monograph of Chinese Enicospilus ( Tang 1990).
Material examined.
1♂: Nepal .
Type series: holotype ♂, Kakani (2,070 m), Nepal, 1-23.VIII.1983, M.G. Allen leg. ( NHMUK) (Figs 2B, H View Figure 2 , 25 View Figure 25 ) .
Distribution.
Nepal.
Description.
Male (Holotype) (Figs 2B, H View Figure 2 , 25 View Figure 25 ). Body length ca 24.5 mm.
Head with GOI = 2.5 (Fig. 25C View Figure 25 ). Lower face 0.9 × as wide as high, moderately punctate with setae and shiny (Fig. 25B View Figure 25 ). Clypeus 1.7 × as wide as high, moderately punctate with setae, moderately convex in profile, lower margin impressed (Fig. 25B, C View Figure 25 ). Malar space 0.4 × as long as basal mandibular width (Fig. 25B, C View Figure 25 ). Mandible weakly twisted by ca 25°, very long, proximally strongly narrowed, centrally to apically subparallel sided, its outer surface with a diagonal setose deep groove between dorsoproximal corner to base of mandibular apical teeth (Figs 2B View Figure 2 , 25B, C View Figure 25 ). Upper mandibular tooth 2.1 × as long as lower one, stouter than lower one (Figs 2B View Figure 2 , 25B View Figure 25 ). Frons, vertex and gena moderately shiny with fine setae (Fig. 25B-D View Figure 25 ). Posterior ocellus close to eye, separated from eye by less than 0.1 × its own maximum diameter (Fig. 25B-D View Figure 25 ). Ventral end of occipital carina joining oral carina. Antenna incomplete apically, right antenna with 64 flagellomeres and left antenna with 65 flagellomeres; first flagellomere 1.9 × as long as second; 20th flagellomere 2.2 × as long as wide.
Mesosoma entirely moderately shiny with setae (Fig. 25E View Figure 25 ). Pronotum punctate dorsally and punctostrigose centrally to ventrally (Fig. 25E View Figure 25 ). Mesoscutum 1.5 × as long as its maximum width, densely and finely punctate with setae, rather weakly shiny, and evenly rounded in profile (Fig. 25E View Figure 25 ). Notauli absent (Fig. 25E View Figure 25 ). Scutellum moderately convex, moderately punctate with setae, with lateral longitudinal carinae almost reaching posterior end (Figs 2H View Figure 2 , 25E View Figure 25 ). Epicnemium densely punctate with setae. Epicnemial carina present, evenly weakly curved to anterior, its dorsal end not reaching anterior margin of mesopleuron (Fig. 25E View Figure 25 ). Mesopleuron entirely weakly to moderately punctostriate to reticulate-strigose longitudinally (Fig. 25E View Figure 25 ). Submetapleural carina almost parallel sided centrally and weakly broadened anteriorly (Fig. 25E View Figure 25 ). Metapleuron densely punctostriate with setae (Fig. 25E View Figure 25 ). Propodeum almost evenly rounded in profile; anterior transverse carina complete centrally, its lateral end almost joining pleural carina; pleural carina vestigial; anterior area longitudinally striate; spiracular area strongly shiny and finely punctures with setae; posterior area rather moderately rugose; propodeal spiracle elliptical, its outer margin not joining pleural carina by a ridge (Fig. 25E View Figure 25 ).
Wings. Fore wing length ca 15.5 mm with AI = 0.4, CI = 0.4, DI = 0.3, ICI = 0.5, SDI = 1.3, SI = 0.1, SRI = 0.3; vein 1m-cu&M almost evenly curved; vein 2r&RS almost straight and RS evenly curved; fenestra and sclerites of discosubmarginal cell as in Figure 25F View Figure 25 ; proximal sclerite triangular, confluent with distal sclerite, moderately pigmented; central sclerite absent; distal sclerite weakly pigmented; proximal corner of marginal cell uniformly setose; posterodistal corner of second discal cell ca 95°; posterodistal corner of subbasal cell ca 90°; vein 1cu-a antefurcal to M&RS by 0.3 × 1cu-a length (Fig. 25F View Figure 25 ). Hind wing with NI = 1.8, RI = 1.5; vein RS straight; vein RA with 6 uniform hamuli.
Legs. Ventral 0.7 of outer surface of fore tibia with rather dense spines. Hind leg with coxa in profile 1.8 × as long as deep; basitarsus 2.0 × as long as second tarsomere; fourth tarsomere 0.7 × as long as third tarsomere and 5.0 × as long as wide; tarsal claw simply pectinate.
Metasoma with PI = 2.8, DMI = 1.3, THI = 2.1; dorsal margin of tergite 1 slightly sinuous; thyridium elongate (Fig. 25A View Figure 25 ).
Colour (Fig. 25 View Figure 25 ). Entirely testaceous except for apex of mandible black. Wings hyaline; proximal sclerite testaceous, distal sclerite very weakly pigmented; veins brown.
Variation. Unknown.
Female. Unknown.
Differential diagnosis.
Enicospilus tangi sp. nov. can be confused with E. kakanicus sp. nov., E. longitarsis , and E. yonezawanus , all of which belong to the E. ramidulus complex. Among these species, E. tangi sp. nov. is most closely related to E. longitarsis , and these species are distinguished from the other Oriental species of Enicospilus by the triangular proximal sclerite (e.g. Fig. 25F View Figure 25 ), the absence of the central sclerite (e.g. Fig. 25F View Figure 25 ), moderately large value of SDI (over 1.3) (e.g. Fig. 25F View Figure 25 ), a diagonal setose deep groove of the mandibular outer surface (e.g. Fig. 2B View Figure 2 ), moderately large fore wing fenestra (e.g. Fig. 25F View Figure 25 ), rather dense spines on the outer surface of the fore tibia, etc. Enicospilus tangi sp. nov. is distinguished from E. longitarsis by the following character states: scutellum narrowed posteriorly (Fig. 2H View Figure 2 ) (subquadrate in E. longitarsis ); fore wing vein 1m-cu&M evenly curved (Fig. 25F View Figure 25 ) (slightly sinuous in E. longitarsis ); lower face 0.9 × as wide as high (Fig. 25B View Figure 25 ) (0.8 in E. longitarsis ); GOI = 2.5 (Fig. 25C View Figure 25 ) (1.8 in E. longitarsis ).
