Geosesarma De Man, 1892

Type species. Sesarma (Geosesarma) nodulifera De Man, 1892 , subsequent designation by Serène & Soh (1970).

Remarks. The genus continues to grow as more areas are surveyed and new taxa discovered; with the total now standing at 59 ( Ng, 2017). The number of Geosesarma species known from Indonesia is certain to grow, and the authors are aware of more populations, some with distinctive colours, which will need to be studied. From Java, six species are known at present: G. noduliferum ( De Man, 1892) [Bogor, west Java], G. confertum ( Ortmann, 1894) [Tjibodas, west Java], G. rouxi ( Serène, 1968a) [Poedjon, east Java], G. bicolor Ng & Davie, 1995 [Ujung Kulon, Banten], G. dennerle Ng, Schubart & Lukhaup, 2015 [Cilacap, central Java], and G. hagen Ng, Schubart & Lukhaup, 2015 [Cilacap, central Java]. In this paper, we redescribe the first three species as well as describe five new species from forests surrounding Mount Halimun Salak National Park in West Java.
