| contents | <p><b><i>PERISESARMA</i> DE MAN, 1895</b></p><p><i>Type species:</i> <i>Sesarma dusumieri</i> H. Milne Edwards, 1853, subsequent designation by Campbell, 1967; gender neuter (see Ng <i>et al.</i>, 2008).</p><p><i>Diagnosis:</i> Small to medium sized crab (up to about 3.4 cm carapace width in studied material). Carapace squarish (slightly broader than long), carapace regions distinguishable, not well marked, lateral margins of carapace with a small epibranchial tooth. Male chelipeds robust, with two oblique rows of pectinated crests on upper surface of palms, followed by 2–4 small tubercles with chitinous peak on inner sides, the crests composed of tall chitinous teeth, chela dactylus with dorsal tuberculation. Walking legs relatively flat. Pleon of male relatively long, triangular, somite 6 considerably elongated, telson small and narrow, longer than wide. Male press button is proportionally large. Female vulvae are positioned completely in sternite 5 with operculum located on inner side and accompanied by a large sternal cover on the anterior side.</p><p><i>Remarks:</i> This genus is now restricted to a single species. Here we take the opportunity to briefly redescribe <i>P. dusumieri</i> concerning its key characters, as it has not been adequately illustrated to date.</p> |
