Diagnosis. This species is distinctive through its relatively broad frons with short frontal setae and greatly enlarged ocelli, and the peculiar, separated appearance of the longitudinal sclerites of the phallus. Description. Body 1.6–2.4 mm long. Frons dark brown and relatively wide; frontal width range 0.52–0.59. Frontal ratio 0.82–0.88. 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 not strongly separated from rest of frons, with large, rounded posterior margin. Lateroventral part of frons with white triangular region with thin black line. Scutum yellowish-brown. Scutellum 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 and one slightly more apical anterodorsal seta present; 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 0.53 wing length; range 0.51–0.55. Costal sector ratios 2.5–3.56:1. Halter knob brown. Abdominal tergites yellowish-brown. Epandrium with slightly rounded dorsal margin and asymmetrical ventral margin; length slightly greater than depth, with depth decreasing posteriorly. Large triangular process present anteroventrally and smaller triangular process midlength; smaller triangular process more rounded than corner of smaller triangular process on E. harveyi . Setae on posteroventral margin of epandrium same length as setae on cercus; setae present on ventral margin ending at slightly rounded process twice the length of setae on cercus. Phallus relatively elongate, greater than length of epandrium, strongly curved, and pointed posteriorly. Strong separation of sclerites near base of phallus present. Distribution. Thailand and Malaysia . Etymology. From Latin for separate, referring to the phallus sclerites. HOLOTYPE . ♂ .
