Five new species of Rogmocrypta: R. karolinae (♀), R. koniambo (♀), R. patryki (♀), R. raveni (♀), and R. rollardae (♀) are diagnosed, described, and illustrated. The definition of the genus is ammended and its distribution and relationships are discussed.

The fauna of New Caledonia is often discussed in terms of Gondwanan heritage. Indeed, the island group was separated from Gondwana some 85 MYA, but later experienced multiple subductions and submergences (
Our initial aim is to present a complete revision of the genus; however, the lack of type material for R. nigella Simon, 1900 and R. puta Simon, 1900 limited our goals.
The material was obtained from the following collections:
The examination specimen methods were as described by

Dr Christine Rollard (Museum National d’Histoire Naturelle, Paris) and Dr. Robert Raven (Queensland Museum, Brismane) provided specimens for study and generous help during our visits (BP & MŻ) to their institutions. Prof. Wayne Maddison (Vancouver, Canada) and Dr. Dmitri Logunov (Manchester, United Kingdom) reviewed the manuscript and provided critical comments and suggestions. The research is part of the project 18/91/S conducted in our university.
