The Asian land planarian fauna Tricladida: Terricola

摘要

Terrestrial flatworms have been extensively studied in Asia for the past century with 208 spp. being recognized in South East Asia and 32 spp. in the Far East. The dominant family is the Bipaliidae with 136 Bipalium spp. The following genera of the Rhynchodemidae are prominent: Dolichoplana (7 spp.), Platydemus (5 spp.) and Rhynchodemus (18 spp.) (Rhynchodeminae); Othelosoma (7 spp.) and Microplana (7 spp.) (Microplaninae). More restricted rhynchodemid genera are Cotyloplana (6 spp.), Digonopyla (2 spp.) and Pseudartiocotylus (1 sp.). In the Geoplanidae, there are no Asian Geoplaninae; a few genera of Caenoplaninae: Artioposthia (1 sp.), Caenoplana (4 spp.), Kontikia (5 spp.); Pelmatoplaninae (13 spp.) are mainly in the Oriental Region: Beauchampius (9 spp.) and Pelmatoplana (4 spp.). Globally, species inquirendae are common and hamper modern classification.
