Diagnosis

Orionis shillongensis Gupta, van Achterberg & Pattar sp. nov. can be distinguished by having the hind coxa dorso-apically rugose-punctate, apical part of the first tergite parallel-sided in dorsal view ( Fig. 4C ), hind femur 5.8 × as long as wide, POL 1.1 ×OOL ( Fig. 3B ), eye in dorsal view 3.1 × as long as temple ( Fig. 3B ) and the ovipositor sheath about 1.3× length of the first tergite.

Etymology

Named after its type locality.

Type material

Holotype

INDIA • ♀, on card; Meghalaya, Shillong ; 1525 m a.s.l; 15 Jun. 2013; A. Gupta and V. Naveen leg.; sweep net; NIM / NBAIR / Hym / Brac / Orio / 150613-H .

Paratype

INDIA • 1 ♂, on card; same data as for holotype; NIM / NBAIR / Hym / Brac / Orio / 150613-P .

Description

Female (holotype ( NIM / NBAIR / Hym / Brac / Orio / 150613-H) , Fig. 2 )

COLOUR. Head, mesosoma and T1 black; antenna brown; mandibles, labial and maxillary palpi yellowish brown; metasomal tergites beyond T1 dark brown dorsally; ovipositor yellow with sheath dark brown; legs mainly brown ( Fig. 2 ). Wings weakly tinged brown, veins and pterostigma dark brown.

MEASUREMENTS. Body length 6.3 mm; ovipositor length 1.7 mm; fore wing length 4.7 mm.

HEAD. Antenna more than 26 antennomeres (apex of antenna missing), third antennomere as long as fourth antennomere, and both 2.7× as long as wide; minute ocular setae present; face densely setose, becoming denser above clypeus; in dorsal view temples strongly curvedly narrowed behind eyes, eye 3.1× as long as temple ( Fig. 3B ), face distinctly narrowed below ( Fig. 3A ); occipital carina visible in dorsal view. POL:OOL:OD (relative) 23:21:11. Eye 2.3× as long as minimum distance between eyes in anterior view; malar space 0.4 × as long as basal width of mandible.

MESOSOMA. Pronotum rugose-punctate, partially smooth medially and concave anteriorly; middle lobe of mesoscutum coarsely punctate posteriorly, notauli crenulate, lateral lobes of mesoscutum with fine punctures, setae present near its apical margin, scutellar sulcus with 7–8 crenulae; propleuron with coarse spaced punctures; mesopleuron mostly setose, irregularly crenulate-rugose, smooth medially; propodeum coarsely irregularly areolate-rugose and punctate; median depression of propodeum relatively shallow ( Fig. 3F ). Hind femur 5.8× as long as wide; hind coxa dorsally rugose-punctate or coarsely reticulate ( Fig. 4C ).

WINGS. Fore wing: m-cu clearly postfurcal (= distad to 2-SR); 1-R1 1.2× as long as pterostigma. Hind wing cu-a:1-M: 1r-m = 25:54:27.

METASOMA. Tergites mainly smooth, but T1 with some coarse punctures ( Fig. 4C ). T1 0.6× as long as mesosoma; T1 about 6.2× as long as its apical width; apical width of T1 2.5× its narrowest subbasal width ( Fig. 4C ); ventrally anterior half of T1 nearly closed and spiracles near middle of tergite; ovipositor sheath about 1.3 × as long as T1.

Male (paratype (NIM/NBAIR/Hym/Brac/Orio/150613-P), Figs 5–6 )

Similar to female in general appearance. Body length 6.4 mm; fore wing length 6.4 mm. Antenna with 37 antennomeres. T1 about 7.6× as long as its apical width. Hind femur 5.6× as long as wide. Differs from female in having malar space 1.1× as long as basal width of mandible, longer interocular distance and longer flagellomeres.

Comments

The new species differs from the closely similar O. coxator (Belokobylskij, 1995) in having the ovipositor sheath about 1.3 × length of first tergite (vs 1.4–1.6 × in O. coxator ); hind coxa dorso-apically rugose-punctate (vs hind coxa dorso-apically with curved striae in O. coxator ); in dorsal view posterior part of T1 parallel-sided and mainly smooth (vs in dorsal view posterior part (= behind spiracles) of T1 widened and densely longitudinally striate in O. coxator ); hind femur 5.6–5.8× as long as wide (vs 4.3–4.8 × in O. coxator ).

Distribution

Known only from Shillong, Meghalaya in north-eastern India.
