Diagnosis. This species is similar to E. ratanae , but the phallus is longer and more strongly curved basally.

Description. Body 2.4–2.6 mm long. Frons brown and relatively narrow; frontal width range 0.44–0.47. Frontal ratio 1.04–1.14. Twelve large frontal setae present, including one pair of supra-antennal setae. Ventral interfrontal setae same width apart as dorsal interfrontal setae. Ocellar triangle dark brown and strongly separated from rest of frons, with rounded posterior margin. Lateroventral part of frons with white triangular region with thin black line. Scutum yellowish-brown. Scutellum light brown, short, broad, with four subequal setae. Pleuron yellowish-brown dorsally to whitish ventrally. Foretibia with anterodorsal row of several slightly differentiated setae, decreasing in size apically. Midtibia with one posterodorsal seta near base, one slightly more apical anterodorsal seta present, and one anterodorsal seta at or above midlength; dorsally with setal palisade extending from base to midlength, more apically with transverse rows of fine setulae; few posterodorsal setae slightly enlarged apically. Hind tibia with several scattered medium-sized anterodorsal setae; dorsally with complete setal palisade, with row of small posterodorsal setulae closely parallel, followed more posteriorly by bare space before regular setulation. Wing large; mean costal length 0.50 wing length; range 0.49–0.51. Costal sector ratios 3–3.45:1. Halter knob yellowish-brown. Abdominal tergite 1 yellow, large, and extending laterally on segment. Tergite 2 yellow except more brown laterally. Tergites 3–6 brown. Epandrium somewhat rectangular but slightly rounded dorsally; length greater than depth. Ventral margin of epandrium strongly rounded on posteroventral margin, with small triangular process midlength, and with long, narrow triangular process anteroventrally. Setae approximately twice as long as setae on cercus present on posteroventral rounded process to small triangular process. Phallus elongate with length approximately same as length of epandrium. Phallus curved at base; straight and consistently broad for remainder of length. Basal half of phallus darkly sclerotized; apical half of phallus with weakly sclerotized broad ventral process. Sclerites of phallus seperate at apex.

Distribution. Philippines.

Etymology. Latin for broad, referrning to the broad phallus.
