Figs 3 , 18 i–l

Description. Ground color light tawny, dorsum infuscated (specimen preserved in ethanol before examined), eyes grey, frontoclypeal area and anteclypeus tawny. Crown fore margin parallel to hind margin, coronal suture distinct; anteclypeus relatively broad.

Anal tube appendage broad, extended from apex of anal tube.

Pygofer with oblique boundary between basal and distal lobes; ventral appendage tubular, curved inwards, not surpassing hind margin of lobe, without rigid setae at base. Subgenital plate with about 3 macrosetae. Style with apical part slim and long, curved outwards in dorsal view. Connective with manubrium long and relatively broad, widened apically, margin of central lobe straight. Aedeagal shaft long, curved dorso-cephalad, atrium long but narrow in lateral view, broadened in caudal view, with serrated lamellae on dorso-lateral edges near base; dorsal apodeme rudimentary; paired preatrial processes short and straight, shifted to base of shaft, near each other.

Measurement. Male length 3.10 mm.

Material examined. Holotype: ♂, THAILAND, Prachuab Khiri Khan , Khao Sam Roi Yot NP, 200m /s of Checkpoint 1, 12°12.789'N, 99°58.662‘E, 19–26 x 2008, Malaise trap, coll. Yai & Amnad. [ QSBG].

Etymology. The new specific epithet is derived from the Latin adjective “ brevis ” which means short, small, referring to the short preatrial processes.

Diagnosis. The new species is similar to E. decembris (Dworakowska) , but the anal tube appendage is broader and curved, the pygofer ventral appendage is curved, the style has a much longer apex, and the aedeagal shaft is curved dorso-cephalad with the dorso-lateral edges serrated and lamelliform.
