New records of freeliving marine nematodes from hong kong, china

Six species of new records collected from intertidal mangrove/non-mangrove and subtidal cave sediments during a mangrove ecological study (1998–2001) and a marine cave expedition (2002) in Hong Kong waters are redescribed. These include two enoplids: Anoplostoma viviparum in Anoplostomatidae and Trissonchulus janetae in Ironidae, two chromadorids: Paracomesoma dubium and Actarjania splendens in Comesomatidae, and two monhysterids: Parodontophora marina and Parodontophora c. f. danker in Axonolaimidae. Five of them are the first records from China. Ecological and taxonomic remarks are provided and discussed in comparison with the original descriptions.
