Sesarmops Sinensis
''Sesarmops'' is a genus of crabs in the family Sesarmidae. Its members are distributed through the Indo-West-Pacific oceanic region. They live in Fresh water, freshwater forest streams near the coast, and in mangroves. Taxonomy ''Sesarmops'' was defined in 1970 when Serène and Soh re-organised the existing genus ''Sesarma''. They included five species: ''S. atrorubens'', ''S. impressus'', ''S. intermedius'', ''S. mindanaoensis'', ''S. sinensis''. Serène and Soh defined ''Sesarmops'' as having (1) the carapace as long or longer than the width measured at the external orbital teeth, (2) the frontal margin has a deep median concavity, (3) the postfrontal lobes are prominent, (4) the external orbital tooth is clearly separated from the rest of the lateral margin by a distinct cleft, (5) with the gastric and cardiac regions well defined. Ng et al. provisionally added ''Sesarma weberi'' in 2008, Paulay and Starmer (2011) transferred ''Sesarma angustifrons'' to the genus in 2011. ...
