Filling a gap in the distribution of Taulidesmella tabatinga (Polydesmida, Pyrgodesmidae): a new record from the upper Amazon River, Brazil

ABSTRACT The millipede species Taulidesmella tabatinga is known from the border of Brazil with Peru and Colombia, Iquitos (Peru), and environs of Manaus (Brazil). Based on freshly collected material during the rainy season in 2014 along the Amazon River upriver from its confluence with the Negro River, we report a new record of T. tabatinga in floodplain forests in the municipality of Alvarães, Amazonas state (Brazil), filling a gap of 1,000 km between its previously known occurrence points. This record indicates that T. tabatinga is likely widespread along both margins of the upper Amazon River, mostly associated with tree trunks and litter of riparian and floodplain forests.
