Distribution.
Eastern Palaearctic region.
JAPAN: [ Kantô-Kôshin] Tôkyô (Miyake-jima Island).
Bionomics.
Unknown.
Differential diagnosis.
This species is more or less similar to E. laqueatus , but easily distinguished by the position and shape of the central sclerite: central sclerite positioned in the anterodistal part of the fenestra, smaller and moderately sclerotised in E. takakuwai sp. nov., as in Fig. 48F View Figure 48 , but positioned in the centrodistal part of the fenestra, larger and strongly sclerotised in E. laqueatus , as in Fig. 24F View Figure 24 .
Description.
Male (HT). Body length ca. 16.5 mm.
Head with GOI = 3.2 (Fig. 48D View Figure 48 ). Lower face 0.8 × as wide as high, strongly shiny, finely punctate with setae (Fig. 48B, D View Figure 48 ). Clypeus 1.5 × as wide as high, finely punctate with setae, convex in profile, and ventral margin acute (Fig. 48B, D View Figure 48 ). Malar space 0.4 × as long as basal mandibular width (Fig. 48B, D View Figure 48 ). Mandible moderately twisted by 15°, moderately long, evenly narrowed, outer surface with diagonal setose groove (Fig. 48B, D View Figure 48 ). Upper tooth of mandible 1.4 × as long as lower (Fig. 48B View Figure 48 ). Frons, vertex and gena strongly shiny with fine setae (Fig. 48B-D View Figure 48 ). Posterior ocellus touching eye (Fig. 48B-D View Figure 48 ). Ventral end of occipital carina joining oral carina. Antennae with 59 flagellomeres; first flagellomere 1.8 × as long as second; 20th flagellomere 2.1 × as long as wide.
Mesosoma entirely rather weakly shiny with fine setae (Fig. 48E View Figure 48 ). Pronotum fairly extensively diagonally striate (Fig. 48E View Figure 48 ). Mesoscutum 1.5 × as long as maximum width, finely punctate, and evenly rounded in profile (Fig. 48E View Figure 48 ). Notauli absent (Fig. 48E View Figure 48 ). Scutellum with lateral longitudinal carinae along entire length of scutellum. Epicnemium punctate with setae. Epicnemial carina strong, almost straight, inclined to anterior, dorsal end not reaching anterior margin of mesopleuron (Fig. 48E View Figure 48 ). Meso- and metapleuron evenly moderately longitudinally striate (Fig. 48E View Figure 48 ). Submetapleural carina broadened anteriorly (Fig. 48E View Figure 48 ). Propodeum declivous in profile; anterior transverse carina complete; anterior area longitudinally striate; spiracular area smooth; posterior area entirely moderately reticulate; propodeal spiracle elliptical and joining pleural carina by ridge (Fig. 48E View Figure 48 ).
Wings (Fig. 48F View Figure 48 ). Fore wing length ca. 11.0 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 evenly weakly curved; vein 2r&RS almost straight; vein RS evenly curved; fenestra and sclerites of discosubmarginal cell as in Fig. 48F View Figure 48 ; proximal sclerite triangular, not confluent with distal sclerite, strongly pigmented; central sclerite D-shaped, moderately sclerotised, and positioned in anterodistal part of fenestra; distal sclerite weakly pigmented; proximal corner of marginal cell rather sparsely setose, but without glabrous area; posterodistal corner of second discal cell ca. 100° and of subbasal cell ca. 90°; vein 1cu-a antefurcal to M&RS by 0.2 × length of 1cu-a. Hind wing with NI = 2.3; vein RS straight; vein RA with 7 uniform hamuli.
Legs. Hind leg with coxa in profile 1.7 × as long as deep; basitarsus 1.9 × as long as second tarsomere; fourth tarsomere 3.3 × as long as wide; tarsal claw simply pectinate.
Metasoma with DMI = 1.4, PI = 3.3, THI = 4.5; thyridium oval.
Colour (Fig. 48 View Figure 48 ). Head and mesosoma entirely yellow-brown except for apex of mandible black. Metasoma dark brown. Wings hyaline. Fore wing sclerites pigmented and amber. Wing veins red-brown to amber.
Female. Unknown.
