Material examined

One on slide. BRAZIL, Amazonas State: Presidente Figueiredo municipality, forest leaf litter of Amazon Rainforest, coordinates 02°01'13"S, 59°49'29"W, 20.IV.2008, Hamada, Azevedo, Neiss, Pes & Meneses leg. (CM/ MNRJ slide number 2535).

Remarks

Neanurinae includes seven tribes worldwide ( Lobellini , Morulodini , Neanurini , Paranurini , Paleonurini and Sensillanurini ) and is poorly known in the Neotropical region, with 75 recorded species - around 10% of a total of approximately 750 species. Only Paleonurini occurs in Brazil, with five genera and six species, Australonura gili Queiroz & Deharveng, 2014, Australonura neotropica Queiroz & Deharveng, 2014, Ectonura snowdeni , Itanura brasiliensis Arlé, 1959, Paleonura nuda Cassagnau & Oliveira, 1990 and Pronura amazonica Cassagnau & Oliveira, 1990, the last two found in the Amazon Region ( Zeppelini et al. 2018). Ectonura includes 17 species around the world, 11 of them from New Caledonia, five from South Africa and only one, Ectonura snowdeni , from mountains in the state of Minas Gerais, southeast Brazil. Moreover, the occurrence of Ectonura sp. from Australia was mentioned in an ecological work, but without a formal species description ( Greenslade and Deharveng 1990). A single specimen of Ectonura was found in a sample collected next to Amazonian Igarapés from Presidente Figueiredo municipality. Due to its poor state of conservation, only diagnostic characteristics for the genus level were identifiable, especially the central cephalic region with few tubercles and chaetal group arrangement. Despite being impossible to identify at species level, it still accounts for the second record of the genus for Neotropical Region and the first for the State of Amazonas, which implies a wider distribution within the tropics of the new world.
