Euphranta haldwanica Hancock & Goodger , sp. nov.

( Figs 43–48 )

Description. Male ( Fig. 43 ). Body length, 8. 7 mm; wing length, 8. 4 mm.

Head ( Fig. 44 ): oval, slightly higher than long. Frons fulvous, with three frontal setae and one orbital seta, all black and acuminate, the frontal setae widely separated and the upper not very close to the orbital seta; ocellar seta vestigial. Antenna shorter than face, scape and first flagellomere brown, pedicel orange, first flagellomere apically rounded and narrowing slightly; arista ( Fig. 45 ) short-plumose. Face concave, yellow with a pair of subtriangular brown spots on oral margin; gena, parafacial and occiput fulvous; postocellar, medial and lateral vertical setae distinct; postvertical setae weak; postocular row thin and black.

Thorax ( Fig. 43 ): mostly dark fulvous to red-brown; scutum with a pair of dark red-brown dorsocentral vittae and a dorsolateral band interrupted at suture; medial band dark fulvous except with a large yellow patch posteriorly; presutural and postsutural yellow vittae present; also postpronotal lobes, notopleuron, suture, katatergite and broad anepisternal stripe yellow; brown band on anterior part of anepisternum extending onto katepisternum. Thorax with full complement of setae except presuturals lacking; dorsocentrals placed midway between line of supra-alars and prescutellars; 1 anepisternal seta. Scutellum yellow with broad, semicircular basal band medially; two pairs of scutellar setae. Haltere yellow.

Legs: femora fulvous except mid femur brown on basal 1/3 and hind femur brown on medial 2/5, fulvous on basal 1/5 and apical 2/5; fore femur with rows of posterodorsal and posteroventral black setulae. Tibia brown; basitarsus fulvous, remaining tarsi brown.

Wing ( Fig. 46 ): length (holotype) 8.4 mm; stigma about 2.5× as long as broad; R-M crossvein just beyond apex of stigma; R1 setose; R4+5 setose to just beyond R-M; cell bcu with broad apical extension; stigma hyaline to pale yellow with a diagonal, pale brown band medially. Wing hyaline with four crossbands: narrow subcostal band from junction of veins R2+3 and R4+5 below base of stigma, to vein A1 enclosing apex of cell bcu; discal band narrow diagonally across stigma to R4+5 above R-M then straightening to become transverse over R-M to posterior margin in cell cu1, broadening in cells dm and cu1; a narrow subapical band, diagonal from costa beyond tip of stigma to vein R4+5 then straightening and transverse to posterior margin at tip of vein Cu1, enclosing DM-Cu crossvein; a broad preapical band from apical ½ of cell r1 to wing margin in cell m, parallel to subapical band, leaving a narrow, oval, apical hyaline spot at apex of cell r4+5 across all of cell apex; no hyaline spot at apex of cell r1.

Abdomen ( Fig. 47 ): elongate-oval, yellow with brown basal bands, broadening laterally, on segments 2–5.

Female: Fitting description of male except facial spots absent in one paratype; sixth abdominal segment about ½ length of fifth; oviscape fulvous, about as long as segments 4–6, 2 mm long; aculeus ( Fig. 48 ) apically acute, without steps or serrations.

Host plant: Dysoxylum binectariferum Hook f. ( Meliaceae ).

Material examined: Holotype 3, INDIA: Haldwani Division, U.P., 12.iii.1923, R.N. Parker, R.R.D.73, B.C.R.223, Glass Jar A, ex Dysoxylum binectariferum , 19 (BMNH). Paratypes: 4 3 and 3 Ƥ, same data as holotype, ex D. binectariferum (BMNH).

Etymology: Named after the Haldwani district of Uttar Pradesh, from where the type series originates.

Remarks: Similar to E. corticicola and E. dysoxyli but differing in the orientation of the wing bands and in the non-serrate aculeus. This species was misidentified as E. corticicola by Hancock and Drew (2004).
