Figs 5 , 18 q–t

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

Anal tube appendage relatively short, minutely denticulate on distal edge, extended from middle of anal tube.

Pygofer basal lobe obviously larger than distal lobe, boundary between lobes oblique; ventral appendage tubular with furrows, sinuated, long and far surpassing hind margin of lobe, without rigid setae at base. Subgenital plate with distal disc large in lateral view, with about 3 macrosetae. Style with apical part thick and short, almost straight in dorsal view, apex pointed and curved in lateral view. Connective with manubrium short and narrow, margin of central lobe nearly straight. Aedeagal shaft short, directed dorsad, atrium long and wide in lateral view, relatively narrow in caudal view, sides rounded and smooth; dorsal apodeme well developed, lamellate; without preatrial processes.

Measurement. Male length 3.00 mm.

Material examined. Holotype: ♂, THAILAND, Phetchabun, Nam Nao NP Pine forest/ Sambon 1, 16°42.47'N, 101°35.26‘E, 872 m, 16–23 x 2006, Malaise trap, coll. Noopean Hongyothi. [ QSBG].

Etymology. The new specific epithet is derived from Latin adjective “ dentatus ” which means toothed, referring to the denticulate anal tube appendage.

Diagnosis. The new species is similar to E. sinuata (Chiang & Knight), but the anal tube has only one pair of appendages which are much thicker, the pygofer ventral appendage is longer, the subgenital plate has a larger apical disc, the connective has a narrower manubrium, the aedeagal shaft is thicker and shorter, and the aedeagal atrium is smooth laterally in caudal view.
