Statoblasts from the Río Negro , 13 km NW of Manaus , Amazonas State , Brazil , 3° 0.099’ S , 60° 5.623’ W (Site 7), collected 6 May 2018 by T . Wood and B. Okamura . Remarks. The slender statoblasts of this species, previously seen only in January, 2016 near Santarém ( Wood & Okamura 2017 ), were encountered for the first time in the Río Negro near Manaus. While many appeared to be intact, they contained no living material. The canoe-like shape of these statoblasts is so unique that the species has been placed in its own family, Tapajosellidae . While colonies have not yet been found, the occurrence of statoblasts in a different season and in a new location suggests that they may be a constant presence in the Amazon.
