Wing: 5.37 mm long, predominantly hyaline with black transverse bands ( Fig. 7 View FIGURES 2–7 ); pterostigma black, cell r 1 with two hyaline wedges, black patch on Rs and base of cell br, discal band fused with radial band to form a V-shaped pattern; subapical band present and fused to broad apical patch, apex of cell r 4+5 hyaline, crossvein r-m placed beyond middle of cell dm.

Abdomen: 2.97 mm long, elongate oval, tergites 1–4 with a broad medial, subtriangular fulvous band, tergite 5 entirely black ( Fig. 4 View FIGURES 2–7 ).

Postabdomen: oviscape 1.23.mm long, conical, black with two fulvous spots laterobasally ( Fig. 4 View FIGURES 2–7 ); eversible membrane ( 1.19 mm long) with dentate spicules on distal end ( Fig. 9 View FIGURES 8–10 ); aculeus short ( 0.45 mm long) pointed with two preapical indentations and two pairs of preapical setae ( Fig. 8 View FIGURES 8–10 ); spermatheca (only one detected, exact number unknown) elongate-tubular and translucent ( Fig. 10 View FIGURES 8–10 ).

Type material: Holotype ♀, INDIA: Tamil Nadu, Coimbatore, Booluvampatti, Siruvani , 26.vii.2020, Sankararaman, H. ( NBAIR).

Etymology: The species name is a noun in apposition and refers to the type locality.

Remarks: This species can be differentiated from other species of Euphranta by the presence of a V-shaped black band on the wing and prominent subapical band connected to the apical black patch. It belongs in the camelliae group ( sensu Hancock and Drew, 2004) and appears closest to E. hainanensis (Zia) and E. sabahensis Hancock & Drew in having an incomplete subapical hyaline band and the medial brown band across r-m crossvein conspicuously broadened in anterior half of wing and with its basal margin distinctly oblique in cell dm ( cf Hancock and Drew, 2004; Wang, 1998); it differs primarily in the lack of a complete hyaline transverse band between the r-m and dm-cu crossbands and the posteriorly abbreviated medial brown band.
