Scutellum yellow with black, basal, triangular patch. Laterotergite black with fine erect hairs. 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.

Wing ( Fig. 29 ): 4.2 mm long and 1.4 mm wide, with three transverse bands, first preapical band broad, fused with the subapical band medially. Discal band extending from cell sc to dm, subapical band over crossvein DM-Cu uninterrupted reaching anterior margin. Hyaline apical spot in cell r4+5 extends to cell r2+3, m. Pterostigma dark brown 4× as long as broad. R-M crossvein just below the apex of pterostigma. R1 setose, R4+5 setose up to crossvein R-M.

Abdomen ( Fig. 31 ): Segments dark brown to black in ground colour with light fulvous areas towards apex. Epandrium and surstylus as in Fig. 32 . Glans of phallus sclerotised with well developed acrophallus and preaputium, vesica short ( Fig. 33 ).

Material examined: Holotype 3, INDIA: Tamil Nadu, Thandikudi, 1311 m , 10º18’N 77º38’E, 10.xi.2010, Light trap, Yeswanth, H. M (UASB).

Etymology: The specific epithet is a noun in apposition and refers to the type locality.

Remarks: This species can be differentiated from E. maculifemur (de Meijere) by wing pattern and abdominal differences (see Hancock and Drew, 1994) and from E. songhkla by having preapical dark spots on all femora.
