Type material.

Holotype: ♀, India: Meghalaya, Umiam, Ri-Bhoi , 15. xi. 2023, Niladri ( NIM) . Paratype: 1 ♀, same data as holotype ( NIM) .

Etymology.

The species name undulata is derived from a Latin adjective undulatus meaning wavy, referring to the wavy margin of the aculeus tip.

Differential diagnosis.

This species is similar to Euphranta apicalis Hendel, 1915 originally described from Taiwan, in possessing two transverse bands and a subapical fuscous patch on the wing and in general morphology, but can be differentiated based on the narrower r-m crossband, irregular proximal margin of the subapical patch, broad aculeus tip with wavy margin.

Description.

Female (Fig. 13 ). Medium sized ( 5.67-5.83 mm). Head (Fig. 14 ). as long as high (height: 1.20-1.29 mm; length: 1.12 - 1.15 mm; length measured from base of scape to occiput); frons fuscous with broad, dark brown arrow head shaped mark with an anterior notch; two pairs of frontal setae; single, reclinate orbital seta; ocellar seta absent, ocellar tubercle glossy black; medial and lateral vertical setae present; postocellar seta absent, postocular setae thin and black; occiput fulvous with broad, glossy black band, from medial and lateral vertical setae to supracervical seta; gena narrow, fulvous with genal seta. Scape and pedicel dark fuscous to black, postpedicel fulvous; combined length of antennal segments shorter than face, arista plumose. Face fulvous with two broad quadrate patches towards epistomal margin. Thorax (Figs 15 , 16 ). Scutum ( 2.26-2.31 mm long, 1.36-1.61 mm wide) fuscous with 2 pairs of broad, glossy black vittae on presutural area, lateral pair extended to transverse suture, submedial pair extending to level of postsutural supra-alar setae, on postsutural part with pair of black sublateral vittae between dorsocentral and intra-alar lines from base of transverse suture to level of postalar seta; postpronotal lobe and notopleuron fulvous. Thorax with well-developed chaetotaxy: 2 scapular setae, 1 anterior notopleural, 1 posterior notopleural, 1 postsutural supra-alar, 1 postalar, 1 dorsocentral placed little behind level of postsutural supra-alar seta, 1 intra-alar, and 1 prescutellar acrostichal. Scutellum dark fuscous with 2 pairs of scutellar setae. Anepisternum fuscous basally, fulvous apically with single seta posterodorsally, anepimeron fuscous to black with single seta, katepisternum fulvous with single seta, anatergite fuscous with fine, erect hairs, katatergite fuscous, subscutellum and mediotergite dark fuscous to black. Legs (Fig. 16 ). Fulvous, without any dark fuscous to black markings; forefemur without any strong ventral setae, two rows of 5-6 dorsal setae; apex of mid tibia with prominent black spine like seta. Wing (Fig. 18 ). Medium-sized ( 5.18-5.54 mm long), hyaline basally with two transverse bands and broad fuscous marking on apical half with hyaline indentations. Subcostal band continuous from pterostigma to apex of vein CuA; radial-medial band narrow, constricted until cell dm, then broadening posteriorly; broad subapical patch hyaline apically, with small triangular hyaline indentation on apex of cell r 1, quadrate shaped indentation on cell m 1, and triangular indentation on proximal margin in cell r 2 + 3; apex of cell r 4 + 5 with hyaline mark extending into cell r 2 + 3. Abdomen (Fig. 17 ). Slender ( 1.86-1.99 mm long; 0.67-0.89 mm wide), predominantly fuscous, tergite 1 dark fuscous to black, tergites 2-5 with black bands interrupted medially; tergite 6 with a complete band.

Female genitalia. Oviscape (Fig. 19 ) black basally and fulvous apically ( 1.10 mm long); eversible membrane ( 0.8 mm long) shorter than oviscape with conical spicules on distal end (Fig. 20 ); aculeus distinctly shorter ( 0.31 mm long) than oviscape with broad, flat apex with wavy margin (Fig. 22 ); spermathecae dark-brown, bulbous with elongate stalk (Fig. 21 ).

Remarks.

This species was collected in traps with a liquid-based bait made using tender bamboo shoots and yeast for attracting bamboo-shoot fruit flies.
