Myriocoleopsis in Southeast Asia

Abstract

A molecular investigation by Wilson et al. (2006) showing the close relationship between the neotropical Myricoleopsis gymnocolea (Spruce) Reiner & Gradst. and Cololejeunea vuquangensis Pocs & Ninh. from Vietnam, instigated the author to reexamine the latter species. The morphological and anatomical characters of Cololejeunea vuquangensis support its transfer to the genus Myriocoleopsis and the new combination of Myriocoleopsis vuquangensis (Pocs & Ninh) Pocs, comb. nov. is proposed. This is the first record of the South American genus Myriocoleopsis from Asia and a remarkable extension of its known distribution.
