Colour. Brown; head and basal segments of antenna yellowish brown, apical segments dark brown; palpi pale yellowish; mesoscutum, scutellum and propodeum dark brown; fore coxa and tibia pale brown, tarsus yellowish brown but telotarsus dark brown; middle leg pale brown; hind leg yellowish brown but telotarsus dark brown; wing membrane brownish translucent, basal half of pterostigma pale and apical half dark brown; first tergite of metasoma dark brown, second tergite brown with part between both furrows dark brown, third tergite brown with medio-basal part dark brown, remaining segments of metasoma brown; ovipositor sheath dark brown, ovipositor red with apical part dark brown.

Distribution. China (Hainan)

Male. Unknown.

Diagnosis. The new species is similar to E. hoabinicus Belokobylskij & Long, 2005 , but can be separated from the latter by having the first tergite more slender (also in lateral view) with more protruding spiracular tubercles, the grooves of the second tergite more convergent, second tergite irregularly reticulate, third tergite reticulate in medio-basal 0.55 and the colour of this area darker than the rest of third tergite.

Biological notes. Nothing is known about the hosts of this species.

Etymology. From “ret” (Latin meaning “net”), because of the irregularly reticulate second and third tergites of metasoma.
