Diagnosis. Female body (Fig. 7) golden yellowish brown; head in frontal view broader than high; scape slightly flattened, 2.7× as long as wide; pedicel 1.4× as long as wide; clava solid and longer than F1−F6 combined; fore wing 2.6× as long as wide; postmarginal vein 0.8× as long as stigmal vein; hind wing 3.7× as long as wide; ovipositor 1.6× as long as mid tibia.
Female. Holotype. Length, 1.12 mm. Head golden yellowish brown, except darker around ocellar triangle and above and below eyes. Antenna with radicle, scape, pedicel and tip of clava golden yellow, remainder brown. Mesosoma with metallic golden reflections. Fore wing smoky. Legs yellow except all tibiae dorsally brown. Gaster dark brown.
Head (Fig. 8) in frontal view broader than high (37:26); posterior ocellus separated from eye by less than its own diameter; antennal torulus situated below lower margin of eye; eye in frontal view1.4× as high as wide; frontovertex broad, 0.4× head width. Antennal formula 1151 (Fig. 9); scape slightly flattened, 2.7× as long as wide; pedicel 1.4× as long as wide; funicle width gradually increasing, F1 2.3× as wide as long; clava solid and longer than F1−F6 combined; F4 with 2 and F5 with 6 mps; clava with 52–56 mps arranged in seven rows, apical and basal rows incomplete; mandibles somewhat widely separated, bi-dentate with lower tooth slender and sharp, upper tooth basally broad, apically slender and sharp. Relative measurements: (card mounted @ 80×)—head width:height, 37:26; eye width:height, 11:15; frontovertex width 15; POL 6; OOL 1; OCL 1; AOL 4; (slide mounted @ 100×)—scape length:width, 16.5:6; pedicel length:width, 5:3.5; funicle length:width, F1, 1.5:3.5; F2, 1.5:4; F3, 1.5:5; F4, 2.5:6.5; F5, 2.5:8; clava length:width, 14:10.
Mesosoma (Fig. 10), strigate or costulate, and 1.3× as long as wide; pronotum 2.9× as wide as long; mesoscutum 2.6× as wide as long; apex of scutellum with a group of long coarse setae (Fig. 7), and 1.2× as wide as long. Fore wing (Fig. 11) 2.6× as long as wide; costal cell 12× as long as wide; postmarginal vein 0.8× as long as stigmal vein; hind wing 3.7× as long as wide. Relative measurements: (card mounted @ 80×)—mesosoma length:width, 35:26; pronotum length:width, 8:23; mesoscutum length:width, 10:26; scutellum length:width, 16:20; (slide mounted @ 100×)—fore wing length:width, 85:33; costal cell length:width, 36:3; marginal vein length 2.5, postmarginal vein length 8, stigmal vein length 10, hind wing length:width, 56:15; mid tibia length 25; mid basitarsus length 6; mid tibial spur length 4.
Metasoma as long as mesosoma (35:35); hypopygium not extending to apex of gaster; ovipositor (Fig. 12) 1.6× as long as mid tibia. Relative measurements: (card mounted @ 80×)—gaster length 35; (slide mounted @ 100×)—ovipositor length 39.
Material examined. Holotype female (dissected left wings, left antenna and ovipositor on slide under 3 cover slips, remainder on card) labeled “ INDIA: Karnataka, Bangalore, IWST (N13 701; E077 341), 08.vi.2012, Coll. S. Manickavasagam and A. Rameshkumar” through yellow pan traps (EDAU, Reg. No. Enc/014/2015).
Host. Unknown.
Male. Unknown.
Comments. Females of this species can be easily separated from those of the only other known species, P. subplanata, by the characters given in the key. Additionally, the postmarginal vein is shorter (0.8×) than the stigmal vein (vs a little longer than stigmal vein). The left antennae of the holotype of P. antennata has five funiculars but the right antenna has only four funiculars due to fusion of F1 & F2 (Fig. 7).
Etymology. This species epithet is in reference to the species-specific diagnostic characters present in the antenna.
