Abstract
A new orthotrichaceous species, Lewinskya transcaucasica Eckstein, Garilleti & F.Lara, is described, based on several samples collected in the Georgian territories of Greater Caucasus and Lesser Caucasus. The species is best differentiated by its sporophytic characteristics. Its capsules are long ovoid to cup-shaped and smooth and show no differentiation of the longitudinal bands of the exothecial cells. The capsules vary from emerging fully from the perichaetial leaves to having a shortly exserted position. The peristome is double, with an exostome of eight pairs of orange to crimson teeth whose tips are variably cancellated and fenestrated and recurved when dry, and an endostome of eight segments that occasionally alternate with reduced intermediate segments. All of these segments are yellowish to pale orange, mainly linear, uniseriate or partially biseriate, and strongly ornamented on the inner side. The new moss is illustrated and compared with similar taxa around the world.
