Abstract

Pinnatella homaliadelphoides Enroth, S. Olsson, S. He, Shevock & D. Quandt (Neckeraceae, Bryophyta) is illustrated and described from China and India. Morphologically, it differs strongly from all known species of Pinnatella, but shares many features characteristic of Homaliadelphus Dixon & P. de la Varde (Miyabeaceae). The generic placement is therefore evaluated by molecular methods. Sequence data from the plastid rps4-trnT-trnL-trnF cluster as well as the rpl16 group II intron and the nuclear ITS1 & 2 place Pinnatella homaliadelphoides sister to P. foreauana Thér. & P. de la Varde, both sharing the same general geographical distribution range.
