Diagnosis

Dark reddish brown overall, including antennae and legs, with ivory on head and mesosoma as follows: posterior margin of head, all face except medially just from behind fore ocellus (between antennal bases) to base of clypeus (reddish brown), sides of mesoscutum (until tegula, not extending to posterior margin), tegula, two upper and lower mesopleural markings, a large posterior marking on metapleuron (just above hind coxa); mandible with upper tooth 2.0 × as long as lower tooth; clypeus flat in profile, ventral margin truncate; face subquadrate, 1.1 × as high as wide; antenna with 42–44 flagellomeres; mesopleuron and metapleuron finely and densely punctate; basal transverse carina of propodeum distinct, anterior area shallowly punctate to smooth, posterior area shallowly transversely striate; proximal sclerite bright red and dome-shaped, central sclerite totally absent; hind wing with 6 distal hamuli on R1.

Etymology

Named with reference to the similarity of this species to Enicospilus oculator .

COLOUR. Dark reddish brown overall, including antennae and legs, with ivory on head and mesosoma as follows: posterior margin of head, all face except in middle just from behind fore ocellus (between antennal bases) to base of clypeus (dark reddish brown), sides of mesoscutum (until tegula), under fore and hind wings, two upper and lower mesopleural markings, a large posterior marking on metapleuron (just above hind coxa).

HEAD. Mandible moderately twisted, upper tooth distinctly longer than lower tooth, (2.0 × as long as lower tooth), broad at base and narrowed apically, without groove on outer surface, with fine dense setae; labrum 0.4 – 0.5 × as high as wide; clypeus flat in profile, ventral margin truncate; face and clypeus finely but somewhat sparsely punctate; lower face subquadrate, 1.1 × as long as broad; gena strongly constricted behind eyes; occipital carina complete; ocelli distinctly enlarged; antenna with 43 – 44 flagellomeres.

MESOSOMA. Pronotum normal, not visible in dorsal view; mesoscutum densely superficially punctate; epicnemial carina distinct to level of ventral corner of pronotum; postpectal carina weak, just visible laterally while indistinct medially; notauli indistinct; scuto-scutellar groove strong, smooth; scutellum shallowly punctate, slightly longer than its basal width, carinate to near apex; meso- and metapleura densely, finely punctate; basal transverse carina of propodeum weak but distinct especially medially, anterior area shallowly punctate to smooth, posterior area shallowly transversely striate.

WINGS. Proximal sclerite bright red and dome-shaped, central sclerite totally absent; Rs+2 r straight , not thickened; hind wing with 6 distal hamuli on R1.

LEGS. Fore tibia sparsely setose; hind coxa elongate, 2.0 × as long as high; hind trochantellus middorsally 1.2 × as long as broad; hind tarsal claw symmetrical, with 11 – 12 equal-sized teeth.

METASOMA. Laterally flattened, widened posteriorly; T 2 in profile about 3.5 × as long as high; thyridium deep, bar-shaped, extending along basal third of T2.

Male (4 specimens)

B 14; F 9.

Resembles female but differs in the following: head and mesosoma brighter red while metasoma dark reddish brown; ivory markings on mesosoma larger, tegula marked with ivory; mesoscutum laterally with ivory line extending along whole length of it, ending with two large rounded markings, two thin middle lines (absent in female); hind wing with 5 distal hamuli on R1.

BOLD Identification Number

ADB4338.

Remarks

This species closely resembles E. oculator except for the following: central sclerite totally absent (in oculator weakly sclerotized proximally); CI 0.16 (in oculator CI 0.25).

Distribution
