Type species. Sundathelphusa tenebrosa Holthuis, 1979 .

Remarks. Ng & Grinang (2022) revised the Bornean species previously referred to Sundathelphusa Bott, 1969 , and assigned them to a new genus, Borneosa , which they defined by a suite of carapace, male thoracic sternal and G1 characters. Seven species were recognised, with four being new. Sundathelphusa is now restricted to Sulawesi, the Moluccas, and the Philippines.
