Abstract

An account of the Drepanolejeunea subgenus Rhaphidolejeunea in Thailand has been updated based on herbarium specimens and recent collections from field surveys. Five species of Drepanolejeunea, i.e. Drepanolejeunea commutata, D. fleischeri, D. siamensis, D. spicata, and D. yunnanensis are recognized. Of these, Drepanolejeunea commutata, D. fleischeri, and D. yunnanensis are newly reported for Thailand. A key to species, descriptions, distribution ranges and illustrations of each species are provided. The ecology and geographical distribution of the species are noted. Additionally, Drepanolejeunea longicruris is excluded from the country.
