Euphranta neochrysopila David, Freidberg, Hancock & Goodger , sp. nov.

( Figs 34–42 )

Description. Male. Body length 6.54 mm; wing length, 5. 7 mm.

Head ( Fig. 34 ): 1.9 mm wide and 1.4 mm high, slightly higher than long, frons fulvous with dark median longitudinal band to 2nd pair of frontal seta, 3 frontal setae (first two pairs closely placed), 1 orbital seta, 1 lateral vertical seta, 1 medial vertical seta, 1 post ocellar seta and ocellar seta minute. Antenna shorter than face, scape and pedicel fulvous, first flagellomere slight fuscous with short plumose arista. Face fulvous without any markings.

Thorax ( Figs 35 & 36 ): 3.0 mm long and 1.8 mm wide, scutum fulvous/ orange yellow in ground colour with two parallel dark fuscous longitudinal bands from base to apex. Scutellum yellow with basal, triangular black marking. Pleura fulvous in ground colour with dark fuscous markings along the anterior margins of anepisternum, anepimeron, upper margin of katepisternum. Anepisternum, anepimeron and katepisternum with single seta. Anatergite black with fine erect hairs, katatergite fulvous. Chaeotaxy complete, setae; 2 scapular, 1 pospronotal; 1 anterior notopleural, 1 postsutural supra-alar, 1 intra-alar, 1 dorsocentral, 1 prescutellar acrostichal seta.

Legs ( Fig. 36 ). Coxa and trochanter yellow. All femora fulvous without any markings, fore-, mid- and hindtibia dark fuscous, tarsal segments light fuscous.

Wing ( Fig. 38 ): 5.7 mm long with two brown transverse bands and an apical brown patch. Apex of cell r4+5 without hyaline spot. Discal band starts from the base of cell sc, extends to posterior margin over crossvein R-M; subapical band over crossvein DM-Cu continuous up to anterior margin ending just beyond pterostigma. Apical dark brown patch covers the apex of cell r1, r2+3, r4+5 and m. Pterostigma fuscous basally and fulvous apically, about 2.8x as long as broad. R-M crossvein just before the apex of pterostigma. R1 setose, R4+5 setose up to crossvein R-M.

Abdomen ( Fig. 37 ): 2.5 mm long and 1.5 mm wide, fulvous/yellow with two black longitudinal bands extending from the base of the fisrt abdominal segment to the fifth segment. Epandrium and surstylus as in Fig. 39 . Glans of phallus sclerotised towards apical half, hyaline basally, with well developed acrophallus; vesica elongate, 0. 75 of glans ( Fig. 40 ).

Female: Similar to male; length of body (excluding oviscape) 7.5 mm, of wing 6.5 mm. Sixth abdominal segment yellow and slightly shorter than fifth; oviscape yellow, about as long as segments 2–5, 2 mm in length. Aculeus tip blunt with a preapical indentation ( Fig.41 ) Spermatheca elongate and tubular ( Fig. 42 ).

Material examined: Holotype 3, SRI LANKA: Amp. Dist. 140m, Ekgal Aru, Sanct. Jungle, 11–15 Sept.1977, Collected by KVKrombein, PBKarunaratne, TWijesiinhe, MJayaweera (USNM). Paratypes: SRI LANKA: 5 3 and 2 Ƥ, same data as holotype; 1 Ƥ, Mon. Dist., Mau Aru, 10 miles East of Uda Walawe, 100mtrs, 22 Jan.1979, K.V. Krombein, P.B. Karunaratne, T. Wijesiinhe, s. Siriwardane, T. Gunawardane. 1 3, 1 Ƥ swept at bank of Manik R. at galge M. Specint, 6.vii.1963, Ruhunu Nat. Pk., Ceylon, Univ. Lund. Ceylon Expdn. B.M. 1963-651 (USNM); 1 Ƥ, Alntoya, 22.iv. [18]91, Lt Col Yerbury, 1892-192 (BMNH).

Remarks: This species is very similar to E. chrysopila Hendel , but can be separated from the latter by the presence of 3 pairs of frontal setae, the black basal spot on the scutellum, a narrower yellow medial band on abdominal terga III–V and its wing pattern: the yellow-fumose areas are more extensive and the transverse bands are complete and reaching posterior margin in E. neochrysopila , whereas in E. chrysopila the discal band ends in cell dm.
