Figs 6 , 18 u–x

Description. Ground color yellowish-brown, eyes black, gena and lorum pale. Crown fore margin parallel to hind margin, coronal suture distinct basally; anteclypeus very broad.

Anal tube appendage narrow and relatively short, moderately curved, located near middle of anal tube.

Pygofer basal lobe larger than distal lobe, boundary between lobes rounded; ventral appendage tubular with furrows, strongly bent mesad or dorso-mesad, apex exceeding hind margin of lobe, with rigid setae at base. Subgenital plate with about 3 macrosetae. Style with apical part slim and long, slightly curved outwards in dorsal view, apex pointed and slightly curved in lateral view. Connective with manubrium long and narrow, central ridge greatly expanded in lateral view, margin of central lobe straight. Aedeagal shaft long, curved dorso-cephalad, atrium wide but relatively short in lateral view, broadened in caudal view, with serrated lamellae on dorso-lateral edges elongated; dorsal apodeme small, lamellate; paired preatrial processes long, curved dorso-caudad, extended from sides, far from each other.

Measurement. Male length 3.30–3.40 mm

Material examined. Holotype: ♂, INDONESIA, N. Sumatra, Landkat District, Bekulab River , Tambunan-A, 02 viii 1985, Malaise trap, coll. M. E. Irwin. Paratypes: 1♂, same data as holotype ; 4♂, same locality and collector as holotype, collecting dates are 30 vii 1985, 06 viii 1985, 08 viii 1985 and 09 viii 1985. [ INHS] .

Etymology. The new species is named for its type locality, Indonesia.

Diagnosis. The new species is similar to E. obtusa (Dworakowska & Viraktamath) , but the anal tube appendage is narrower and smooth, the style has a slimmer apical part, and the preatrial processes are longer and close to the aedeagal shaft in lateral view.
