Ovipositor sheath length about 0.2 × length of hind tibia. Variation Female The specimen collected in the D.R. Congo has a slightly less protruding clypeal margin. Hind tibia length 4.8–5.0× width. Distribution D.R. Congo, Zimbabwe. Hosts Unknown. Taxonomic comments This is one of the most easily recognizable species of Ecrizotes due to its large triangular clypeal margin, which is expected to be similar in males.
