Geosesarma cf. rouxi

Geosesarma cf. rouxi:

Geosesarma rouxi Serène, 1968 is a terrestrial freshwater crab from the highlands northwest of Maland in East Java near Pujon at around 1,100m above sea level (Ng & Wowor, 2019). Coloration of adult G. rouxi crabs are not described by science so there is a possibility that those of Geosesarma rouxi in captivity are misidentified. They should probably be listed as Geosesarma aff. rouxi until the TGD Team can identify them under a microscope based diagnostic criteria. Something to note as described by Ng & Wowor (2019) is that G. rouxi has a characteristically trapezoidal carapace and a very unique G1 that is short and stout with a very short almost rounded chitinous distal portion which separates itself easily from the other Javan species.

Size of Geosesarma rouxi:

The paratypes were 10.0mm x 9.5mm and 12.6 x 12.3mm (Ng & Wowor, 2019)
