Abstract
Petalocladius dominiensis Andersen & Baranov sp. n. is described and figured based on an adult male collected in the Ebano Verde Scientific Reserve in the Dominican Republic. The new species can be separated from its only congener, P. setosus Sublette & Wirth, 1972 from Jamaica, as it is slightly smaller with about 115 dorsocentrals compared to 56 in P. setosus. The inferior volsella is broadly subtriangular, while more lingulate in P. setosus, and the gonostylus has a small, but distinct megaseta and a subapical brush of spine-like seta, which apparently lack in P. setosus. The generic diagnosis is emended including the new species, and the systematic position is briefly discussed.
