Enicospilus kunigamiensis Shimizu sp. nov. Figure 23 View Figure 23

Etymology.

The specific name is derived from the type locality.

Type series.

A holotype female only.

HT: ♀, Benoki, Kunigami Vil., Kunigami County, Okinawa-hontô, Okinawa Pref., Ryûkyûs, JAPAN, 9.IV.1996, M. Aoyagi leg. (LT) (NIAES).

Distribution.

Oriental region.

JAPAN: [ Ryûkyûs] Okinawa.

Bionomics.

Unknown.

Differential diagnosis.

This species is similar to E. matsumurai sp. nov. but easily distinguishable by the number of antennal flagellomeres (i.e., antenna with 54 flagellomeres in E. kunigamiensis sp. nov. but 59-60 in E. matsumurai sp. nov.), value of ICI (i.e., ICI = 0.4 in E. kunigamiensis sp. nov. but 0.7-0.8 in E. matsumurai sp. nov.), length of lateral longitudinal carinae of scutellum (i.e., lateral longitudinal carinae along anterior 0.2 of scutellum in E. kunigamiensis sp. nov. but more than 0.8 in E. matsumurai sp. nov.), body size (body length ca. 23.0 mm in E. kunigamiensis sp. nov. but 28.0-30.5 mm in E. matsumurai sp. nov.), etc. However, the detailed affinities of E. kunigamiensis sp. nov. are unknown.

Description.

Female (HT). Body length ca. 23.0 mm.

Head with GOI = 2.5 (Fig. 23D View Figure 23 ). Lower face 0.7 × as wide as high, strongly shiny, and smooth with fine setae (Fig. 23B View Figure 23 ). Clypeus 1.4 × as wide as high, smooth, moderately convex in profile, and ventral margin acute (Fig. 23B, D View Figure 23 ). Malar space 0.2 × as long as basal mandibular width (Fig. 23B, D View Figure 23 ). Mandible twisted by ca. 30°, moderately long, evenly rather strongly narrowed, outer surface smooth (Fig. 23B, D View Figure 23 ). Upper tooth of mandible 1.4 × as long as lower. Frons, vertex and gena strongly shiny with fine setae (Fig. 23B-D View Figure 23 ). Posterior ocellus almost touching eye (Fig. 23B-D View Figure 23 ). Ventral end of occipital carina not joining oral carina. Antennae with 54 flagellomeres; first flagellomere 1.9 × as long as second; 20th flagellomere 1.7 × as long as wide.

Mesosoma entirely strongly shiny with setae (Fig. 23E View Figure 23 ). Pronotum finely diagonally striate (Fig. 23E View Figure 23 ). Mesoscutum 1.4 × as long as maximum width, strongly shiny and finely punctate with setae, and evenly rounded in profile (Fig. 23E View Figure 23 ). Notauli absent (Fig. 23E View Figure 23 ). Scutellum moderately convex, rather weakly shiny, punctate, with lateral longitudinal carinae along anterior 0.2 of scutellum. Epicnemium densely punctate with setae. Epicnemial carina present, almost straight and inclined to anterior, dorsal end not reaching anterior margin of mesopleuron (Fig. 23E View Figure 23 ). Dorsal part of mesopleuron smooth to finely punctate and ventral part longitudinally finely punctostriate (Fig. 23E View Figure 23 ). Submetapleural carina broadened anteriorly (Fig. 23E View Figure 23 ). Metapleuron moderately diagonally striate (Fig. 23E View Figure 23 ). Propodeum declivous in profile; anterior transverse carina complete; anterior area longitudinally striate; spiracular area smooth; posterior area moderately rugose; propodeal spiracle elliptical and not joining pleural carina by ridge (Fig. 23E View Figure 23 ).

Wings (Fig. 23F View Figure 23 ). Fore wing length ca. 16.0 mm with AI = 0.7, CI = 0.3, DI = 0.3, ICI = 0.4, SDI = 1.1, SI = 0.1, SRI = 0.3; vein 1m-cu&M almost evenly curved; vein 2r&RS almost straight; vein RS rather evenly curved; fenestra and sclerites of discosubmarginal cell as in Fig. 23F View Figure 23 ; proximal sclerite triangular, faintly confluent with distal sclerite, strongly pigmented; central sclerite not well-delimited and pigmented part suboval, positioned in anterodistal part of fenestra; distal sclerite vestigial; proximal corner of marginal cell evenly setose; posterodistal corner of second discal cell ca. 100° and of subbasal cell ca. 70°; vein 1cu-a antefurcal to M&RS by 0.1 × 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 1.8 × as long as deep; basitarsus 1.9 × as long as second tarsomere; fourth tarsomere 3.1 × as long as wide; tarsal claw simply pectinate.

Metasoma with DMI = 1.4, PI = 3.2, THI = 3.5; thyridium oval; ovipositor sheath not longer than posterior depth of metasoma (Fig. 23A View Figure 23 ).

Colour (Fig. 23 View Figure 23 ). Longitudinal vittae of mesoscutum and metasoma red-brown; apex of mandible black, otherwise whitish yellow. Wings weakly infuscate; sclerites pigmented and amber; vein dark reddish brown.

Male. Unknown.
