Material examined. INDIA- Jammu and Kashmir • ♀; Ganderbal; 34°14’43.1”N, 74°47’02.7”E; 1,639 m; 21 May 2023; D. M. Bhat leg.; Yellow pan trap, (CUZM-D _Bhatl014).
Diagnosis (female)
This species differs from the only other known Inbioia species (I. pivai) by having a di-branched appendage arising from the base of apico-lateral region of tergite VIII (tri-branched in I. pivai) tergite VIII shorter than VII and VI (tergite VIII longer than than VII and VI in I. pivai); malar space wide, about l.3 times as long as the basal width of mandible (1.2 times in I. pivai); hind femur with long dark stripe (some dark blotches of pigment in I. pivai).
Description
Female (holotype)
Body length 4.5 mm. Fore wing length 3mm.
Head (Fig 2B–D). Completely matt, densely covered with short hairs; minimum face width 0.95 times as wide as height of the eye (Fig 2B); inner margins of eyes almost parallel sided; clypeus strongly convex, about 1.6 times as wide as high, separated from face by an impressed clypeo-facial suture, the apical margin truncate with a row of long hairs (Fig 2D); anterior tentorial pits oval, deep and wide; malar space wide, about l.3 times as long as the basal width of mandible; mandible moderately tapering towards apex, the upper tooth a little longer than the lower one; distance between lateral ocelli and eyes 1.6 times as long as diameter of lateral ocellus; occipital carina rather low on head, rounded, complete, meeting the hypostomal carina far from mandible; antennae filiform, with 22 flagellomeres, 1 st flagellomere 5.5 times as long as its apical breadth; 2 nd flagellomere about 0.72 times as long as the lst and equal to 3 rd; 1 st flagellomere:2 nd:3 rd = 1.6:1:1; temporal width (behind frontal ocellus) 1.5 times the width of eye (Fig 2C).
Mesosoma (Fig 2E–F): Thorax granulopunctate with some rugosity laterally, covered with dense, short white hairs; epicnemial carina weak, but distinct, reaching upto the level of lower 3 rd of pronotum ending well before the margin; pronotum short, epomia weak, curved very close to head difficult to visualize due to the striations of pronotum present (Fig 2D); mesoscutum short and convex, lacking impressed notauli, scutellum rugulose with lateral carination (Fig 2F); mesopleuron completely dull, sternaulus absent; propodeum short and rather strongly declivous posteriorly, completely rugose and dull, carination absent except for a vestigial lateromedial longitudinal carinae at the apical margin.
Wings (Fig 2G): Fore wing with 3rs-m entirely absent, 2rs-m long; hind wing with basal abscissa of M + CU strongly and evenly bowed; Cu-a weakly angled, distal abscissa of Cu1 present, weak.
Legs (Fig 2A): Legs stout; coxae rugose with some fine rugulosity; hind femur 3.8 times as long as wide, hind tibia 8.5 times as long as wide; distal tarsal segments swollen, tarsal claws simple and short, with a high basal lobe and enlarged pulvilli.
Metasoma (Figs 2I–K, 3A–B): Abdominal tergites granulate, smoother in basomedian area of tergite I, weak lateral striations on tergites I–II (Fig 2H); sparsely covered with short fine white hairs; tergite I 0.8 times as long as wide, 1.1 times as long as tergite II, its apical width 2.3 times its basal width, tergite II 0.7 times as long as wide; tergite VIII shorter than tergite VII and tergite VI (Fig 2I); tergite V–VI and baso-lateral area of tergite VII–VIII densely covered with long white hairs, tergite VII–VIII and apico-medial area of tergite VI covered with several long black bristles, tergite VII completely covered with long black bristles; a tuft of thick, long black hairs at the apico-medial region of tergite VII; ovipositor sheaths long, reaching beyond cerci, covered with long fine setae; a simple branched appendage, with two branches, covered with black bristles, arising from the base of apico-lateral region of tergite VIII (Fig 3A–B); a pair of extended finger-like structures resembling cerci, covered with short but stiff black bristles (Fig 2I, 3A); ovipositor robust, more or less straight, projecting beyond apex of metasoma, with a slight sub-medial ventral swelling, slightly curved sub-apically (Fig 3A–B).
Colouration: Head reddish orange with an ivory white band covering almost whole face and clypeus, continuing along the sides of antennal sockets (leaving a narrow area around the sockets), forming narrow irregularly arcuate bands running along the eye margin, converging towards the vertex and ending just before occipital carina; clypeus, except for the narrow brownish yellow margin, ivory white, antennae dark brown, basal flagellomeres ivory white in frontal half, medial flagellomeres whitish yellow and terminal flagellomeres brownish yellow; mandibles dark brown; a wide ivory white band running along the malar space and reaching the lower margin of gena; thorax reddish orange with a narrow ivory white band running along the lower margin of pronotum, dorsally faint yellowish white narrow bands running from pronotum along notauli and weakly converging towards apex; wings hyaline grey; legs predominantly whitish with brownish stripes, tarsal claws yellowish white basally, dark brown apically; tergites I–IV pale yellow with yellowish white apical margin, tergites V–VIII black with a wide medial and narrow lateral longitudinal ivory white band on tergite V, tergite VII–VIII with a wide irregular whitish mark in the basolateral corner, cerci greyish black with whitish patches, ovipositor sheath greyish black in basal 2/3 region and ivory white in apical 3 rd
