Epiphyllous liverworts (Marchantiophyta) from Batanta Island (Indonesia, West Papua)

Epiphyllous liverworts were collected in 2017, 2018 and 2019 in the tropical rainforest at low elevation of Batanta Island by the entomologist Tibor Kovács and his colleagues, which were identified by Tamás Pócs. From the 28 species collected at least 14 are new to the western half of New Guinea. These are mostly widespread Indomalesian-Pacific species, but two are endemics, i.e. Cololejeunea streimannii Pócs and Cololejeunea touwii Pócs, which were previously known only from their type localities in Papua New Guinea. Further collections from the higher elevations of the island should be very promising
