Ground color light tawny (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 narrow, almost straight, extended from nearly apex of anal tube. Boundary between basal and distal pygofer lobes almost vertical, except the upper part; ventral appendage tubular, slightly sinuated, apex extended to hind margin of lobe, without rigid setae at base. Subgenital plate with about 2 macrosetae. Style with apical part thick and short, straight in dorsal view, apex pointed and slightly curved in lateral view. Connective with manubrium long and relatively narrow, margin of central lobe convex. Aedeagal shaft long, curved dorsad, atrium long and wide in lateral view, broadened in caudal view, with serrated lamellae on dorso-lateral edges near base; dorsal apodeme rudimentary; paired preatrial processes long, curved dorso-caudad, extended from sides, far from each other. Measurement. Male length 3.20 mm. Material examined. Holotype: ♂, THAILAND, Chaiyaphum, Tat Tone NP Entrance / Pha Eang waterfall, 15°57.52'N, 101°54.442‘E, 26 x–03 xi 2006, Malaise trap, coll. Tawit Jaruphan. [QSBG]. Etymology. The new species is named for its type locality Chaiyaphum (Thailand). Diagnosis. The new species is similar to E. obtusa (Dworakowska & Viraktamath), but the anal tube appendage is narrower, smooth and almost straight, the style has shorter apical part, and the preatrial processes are close to the aedeagal shaft in lateral view.
