Parencyrtomyia zedesi sp. nov.

( Figs 27–31 )

Female: Holotype. Length, 2.15 mm. Head blackish; pronotum anteriorly dark brown, collar laterally and sides brownish yellow; mesoscutum brownish yellow with pale brown suffusions mesally and posteriorly; scutellum same as mesoscutum but with a small brown area in middle; metanotum and propodeum nearly black; tegula brownish yellow in about basal third, but apical two-thirds dark brown; prepectus yellow; mesopleuron black, shiny; gaster with tergites dark brown except T1 mesally yellow, TVII brownish yellow on sides and apex white, and ventrally curved sides of tergites and sternites, including hypopygium, pale yellow to white; third valvula yellow except pale brown apically. Antenna ( Fig. 27 ) with radicle yellow; scape brownish yellow except dorsal margin brownish; pedicel and flagellum dark brown to black. Fore wing infuscate as in Fig. 28 . Hind wing hyaline except for slight pale brown infuscation towards apex. Legs with mid coxa black, otherwise brownish yellow with pale brown suffusions.

Head ( Fig. 31 ). Antennal toruli with their upper margins in line with lower margins of eyes; ocellar triangle with apical angle a right angle; POL 7x as long as OOL, and only slightly (1.07x) longer than OCL; frontovertex with fine, raised reticulate sculpture on vertex and in two lines of punctures on frons on each side in front of anterior ocellus; setae on head largely silvery white, mixed with brown setae especially on vertex and malar space; eyes appear bare, but with sparse, short, transparent setae. Mandible tridentate, middle and upper teeth rounded. Antenna as in Fig. 27 ; F1 measured along ventral length slightly longer than pedicel (18: 15); F5 quadrate, F6 slightly broader than long; clava slightly longer than F4–6 combined, with second suture oblique, and third segment with an oblique truncation. Relative measurements — head dorsal width, 60; frontovertex width at anterior ocellus, 17; eye height, 39; malar space, 22; POL, 7; OOL, 1; OCL, 6.5; AOL, 6; scape length, 36.

Mesosoma. Mesoscutum and scutellum with fine, polygonal reticulations of more or less of similar depth; mesopleuron with fine lineolate reticulate sculpture; setae on mesoscutum largely silvery white mixed with brown setae, those on scutellum brown with a few silvery white setae anteriorly; sides of propodeum setose, setae silvery white; metapleuron with several silvery white setae along lower margin. Fore wing ( Fig. 28 ) 2.80x as long as broad; venation extending 0.52x wing length; disc setose to base proximal to linea calva; marginal vein slightly longer than both postmarginal and stigmal veins ( Fig. 29 ). Hind wing 4.16x as long as broad; venation extending 0.65x wing length; marginal cell with a line of short setae. Relative measurements — mesoscutum length (width), 40 (60); scutellum length (width), 35 (33); propodeum median length, 7.5.

Gaster 0.76x mesosoma length; (hypopygium distorted in slide mount); ovipositor as in Fig. 30 . Relative measurements (paratype, slide) — TVII length, 70; ovipositor length, 96.5; third valvula length, 27; mid tibia length, 107.5; mid basitarsus length, 34.5; mid tibial spur length, 28.

Male. Unknown.

Material examined. Holotype, female (on card) labelled “ INDIA: Arunachal Pr. Namdapha Tiger Reserve, Hornbill, 04.xi.2009, P. M. Sureshan” (“ NZSI 12344/H3” on a red ticket).

Paratype. 1 female (on slide, No. EH. 1314, one antenna missing), Namdapha Tiger Reserve, Aamika Falls, 14.xi.2009, P. M. Sureshan. ( ZDAMU, Registration No. HYM. CH. 620).

Host. Unknown.

Distribution. India: Arunachal Pradesh.

Comments. Parencyrtomyia is newly recorded from India. The new species, P. zedesi , differs from P. niveiclava Girault , the type and only other described species, in several characters, notably the following: head nearly completely black; antennal clava dark brown to black as funicle; mid coxa black; metanotum and propodeum nearly black and dorsum of gaster largely dark brown; fore wing with a distinct infuscation in apical half; malar space 0.56x eye height; torulus slightly less than own height from mouth margin; antennal scape about as long as combined length of pedicel, F1 and F2; clava slightly longer than F4–6 combined; fore wing setose from base, without a bare area; mesoscutum without notaular lines. In P. n i v e i c l a v a: face between and below toruli yellowish brown; clava white; legs yellowish brown; metanotum, propodeum and dorsum of gaster infuscated; fore wing with an indistinct suffusion and with a bare area basally; malar space 0.4x eye height; torulus 1.25x its height to mouth margin; scape slightly shorter than combined length of pedicel, F1 and F2; clava shorter than F4–6 combined. The differences notes are based on the original description, and the notes and figures given by Dahms & Gordh (1997). Other details of P. niveiclava are not available as the mesosoma and gaster of the holotype are on a card. Dahms & Gordh (1997: p.286) state that the mesoscutum has notaular lines (‘parapsidal sutures’) present in its anterior half.

Etymology. The species name is derived from an arbitrary combination of letters.
