DIAGNOSIS Carapace with lateral border defined in third part, and with weak subproximal indentation; no posterolateral striae. Proepistome as small plate inserted under lower frontal margin ( Tavares 1989 : figs 5, 6). Orbit not closed laterally ( Tavares 1989 : fig. 6), suborbital area granulated; suborbital crest very long, descending obliquely (instead of joining external angle of orbit), consisting of minute, close striae (stridulatory pars stridens), rubbing on ridge lined by short setae (plectrum) located on inner margin of P1 merus, present in both sexes. Male chelae with only minor heterochely or with clear heterochely (palm strongly inflated and with large gap between fingers). Thoracic sternum widened; sternite 1 small, triangular, seemingly fused with semi-ovate sternite 2 that bears medially setose transversal depression; suture 2/3 straight; sternites 3 + 4 not restricted at level of P1, thus with rather straight, obliquely directed margins; suture 7/8 short; sternite 7 wide; sternite 8 very wide, due to posterior emargination that does not reach sternite 7; only a minute portion of sternite 8 is dorsally exposed (below setae in E. notatus ) when pleon is folded; no median bridge. Median line on sternite 8 and extending on whole sternite 7; its distal portion bumping at level of suture 6/7 into a median, weakly raised area that superficially units both sides of sternal plate and becomes the bottom of sterno-pleonal cavity. Pleon triangular, with short somite 6; long telson. Male gonopore emerging rather far from P5 coxo-sternal condyle and suture 7/8, sternite 7 joining sternite 8 for a rather long distance. Locking button remarkably large and inflated, occupying more than the middle of sternite 5, with strongly granulated prominence; pleonal socket with markedly calcified margin. Presence of conspicuous setal coxal pouches between P3/P4.
