Antenna 0.76x length of face; scape and pedicel fulvous, first flagellomere fuscous with plumose arista; lateral and medial vertical seta, post ocellar seta well developed, ocellar triangle black with ocellar seta vestigial, postocular setae thin and black. Face fulvous, concave, gena yellow with a stout seta; parafacial yellow, occiput black with medial fulvous marking.

Thorax ( Figs 16 & 17 ): 2.26 mm long and 1.39 mm wide, scutum dark brown to black except yellow median vitta from transverse suture to scutellum; postpronotal lobe yellow. Pleura dark brown to black except for anepisternal stripe extending from postpronotal lobe to wing base. Anepisternum, katepisternum and anepimeron black. Thorax with full complement of setae except presutural setae; 2 scapular, 1 pospronotal; 1 anterior notopleural, 1 postsutural supra-alar, 1 intra-alar, 1 dorsocentral, 1 prescutellar acrostichal, 1 anepisternal and 1 katepisternal seta. Scutellum yellow with two pairs of setae.

Legs ( Fig. 17 ): Fore and mid coxa yellow, hind coxa fuscous. All femora fulvous except apical 1/3rd of fore femur with dark fuscous marking; fore femur with ventral setae. Fore, mid and hind tibia light fuscous.

Wing ( Fig. 15 ): 4.2 mm long and 1.4 mm wide, predominantly hyaline with two transverse bands: discal band extending from pterostigma, reaching cell dm; subapical band fused with anterior apical band. Crossvein r-m placed beyond the level of apex of cell sc.

Abdomen ( Fig. 18 ): 2.44 mm long and 0.80 mm wide, all tergites dark brown to black except tergite III to V with yellow rectangular marking medially. Epandrium and surstylus as in figures 19 and 20. Glans of phallus well sclerotised with acrophallus and vesica ( Fig 21 ).

Material examined. Holotype ♂, INDIA: Andhra Pradesh, Araku Valley, 10º18’N 77º38’E, 10.xi.2013, Light trap, Shakti Kumar Singh ( NPC).

Etymology. The species name is based on its resemblance to Euphranta cassiae (Munro) .

Remarks. This species is similar to E. cassiae with respect to thoracic markings and wing pattern but can be differentiated by the presence of a prominent discal band reaching cell dm and a preapical marking on fore femur.
