Coloration in alcohol obscure. The specimen has dried out at one
time had has been recovered. There are no distinct markings on the
appendages or the abdomen. The propeltidium is dark along the
anterior margin and apparently distinctly dusky on the anterior half. .
Structure essentially the same
as that of E. angustus Muma and E. cruzi Muma except that
the anterior tooth of the movable cheliceral finger is distinctly
tooth-like, the fondal notch is quadrangular, slightly wider than long,
and only slightly narrower or wider than the fixed finger. Figure
16 shows the cheliceral dentition. The above measurements and
ratios are also distinctive except for that of length; the abdomen is
shriveled.
Muma (ibid) further notes that there is
no scopula on the male palpus, and no discernable ctenidia on the first
post-stigmatic abdominal sternite of the male. He speculates that this
species could be a synonym of E. toltecus (Pocock).
