Scandarma , new genus

Type species. – Scandarma lintou , new species, by present designation.

Diagnosis. – Carapace squarish to gently sinuous, lateral carapace margin relatively narrow at exorbital teeth, continuously widening posterior to blunt anterolateral teeth. Palm of male chelae inflated, dorsal surface with longitudinal line of granules, no pectinated crests; dactylus dorsally with longitudinal row of horny tubercles and pollex with ventral row of spiny granules. G1 relatively short and stout; distal chitinous part short and spatulate; G2 short, with elongated distal segment.

Etymology. – The name is derived from the arbitrary combination of the Latin word “scandere” for climbing and the ending of the name “ Sesarma ”, alluding to the tree- and rock-climbing habit of the type species. The gender of the new genus is neuter.

Remarks. – Scandarma , new genus, shares the carapace and some chelipedal characters of Pseudosesarma Serène & Soh, 1970 and Sesarmops Serène & Soh, 1970 , in its lateral carapace margin having one anterolateral tooth and a male chelar palm without pectinated crests. However, Scandarma lintou differs from all known species of Pseudosesarma and Sesarmops in the shape of the carapace and the tuberculation of the male chelae: the dorsal surface of the propodus carries one longitudinal line of granules, the dactylus one longitudinal row of horny tubercles and the pollex is characterized by a row of ventral spiny granules. Furthermore, all known species of Pseudosesarma and Sesarmops have proportionately much broader and shorter ambulatory legs.
