Hampeella concavifolia Hattaway & D. H. Norris (Ptychomniaceae) is described and illustrated from Queensland, Australia. It differs from H. pallens (Sande Lacoste) M. Fleischer in its teretely foliate, attenuate secondary stems; the closely imbricate, strongly concave, symmetrical leaves that have bright orange to red-brown basal cells with incrassate-porose walls; longer capsules (to 2.4 mm); and longer setae (to 14 mm). Hampeella concavifolia is distinguished from H. alaris (Dixon & Sainsbury) Sainsbury by its less differentiated alar cells, usually longer secondary stems (to 3 cm), and differences in peristome ornamentation. This new species is designated as Data Deficient (DD) according to IUCN Red List criteria.
