Diagnosis

Second flagellar segment (F2) of female of Orionis femorator Gupta, van Achterberg & Pattar sp. nov. is nearly as long as first segment (F1) and more than 2.5 × as long as wide, apical third of antenna yellowish ( Figs 7–8 ), POL slightly shorter than OOL ( Fig. 9B ), length of eye in dorsal view 1.9 × temple, hind femur 6.6× as long as wide ( Figs 7–8 ) and ovipositor sheath 0.9–1.5 × as long as first tergite.

Etymology

Named after the comparatively elongate hind femur.

Description

Female ( Figs 7–8 )

COLOUR. Largely black. Frons and clypeus yellowish brown, vertex black, ocelli pale yellow; pronotum and propleuron yellowish brown; mesosoma largely reddish brown; propodeum and T1 black; antenna brown with 11 apical antennomeres yellowish; mandibles except brown tip, labial and maxillary palpi pale yellowish; metasomal tergites beyond T1 dark brown; ovipositor yellowish brown; legs mainly yellowish brown but apex of hind femur, hind tibia and tarsus darkened. Wings weakly tinged brown, veins and pterostigma dark brown.

MEASUREMENTS. Body length 6.3 mm; ovipositor length 2.4 mm; fore wing length 3.8 mm.

HEAD. Antenna with 25 antennomeres, third antennomere (F1) 1.1× as long as fourth antennomere (F2), third and fourth antennomere almost similar in width, third antennomere 4.2 × as long as wide; setae more concentrated surrounding torular region and adjacent to eye margin in posterior half, few above clypeus, evenly and sparsely scattered on vertex; frons smooth except few transverse rugae; vertex smooth; in dorsal view temples slightly curved and directly narrowed behind eyes, eye 1.9 × as long as temple in dorsal view ( Fig. 9B ), occipital carina visible in dorsal view. POL almost equidistant to OOL. POL:OOL:OD = 16:17:9. Eye 2.5 × as long as minimum distance between eyes in anterior aspect; face strongly narrowed below ( Fig. 9A ); malar space 0.3× as long as basal width of mandible.

MESOSOMA. Pronotum mostly smooth medially except for two incomplete lateral rugae, diverging laterally from apical margin, and two sublateral rugae converging medially; mesoscutum finely and sparsely punctulate, sparsely setose; notauli crenulate, meeting posteriorly; scutellar sulcus with two prominent costulae and three carinae; mesopleuron with irregular pattern of rugae marginally, but smooth medially; precoxal sulcus deep and crenulate; propodeum with irregularly arranged large areolae, coarsely rugose, angulate in lateral view ( Fig. 9E ); median depression of propodeum indistinct. Hind femur 6.6 × as long as wide; coxa dorsally rugose-punctate ( Fig. 10C ).

WINGS. Fore wing: m-cu clearly postfurcal (= distad to 2-SR); 1-R1 1.1× length of pterostigma. Hind wing veins cu-a:1-M:1r-m = 20:23:25.

METASOMA. Fist tergite with scattered punctures in posterior half with few longitudinal striae laterally, anterior half with faint rugosity ( Fig. 10C ). T1 0.6× as long as mesosoma and about 3.5 × as long as its apical width; apical width of T1 2.8× its narrowest subbasal width, ventrally basal half of T1 nearly closed and spiracles near middle of T1; ovipositor sheath about 1.5× as long as T1.

VARIATION. Ovipositor sheath 0.9–1.5 × as long as T1.

Male

Unknown.

Comments

The new species differs from the similar O. orientalis Shaw & Shimbori, 2016 by having the face yellowish brown (vs yellow in O. orientalis ); the apical segments of antenna brownish yellow (vs dark brown in O. orientalis ); in lateral view propodeum angulate (vs rounded in O. orientalis ); T1 0.6× as long as mesosoma (vs 0.7 × in O. orientalis ); T1 about 3.5× as long as its apical width (vs 3.7× in O. orientalis ) and ovipositor sheath 0.9–1.5 × as long as T1 (vs 1.6× in O. orientalis ).

Distribution

Known from southern India (Tamil Nadu and Karnataka).
