In this contribution we report specimens from the Brazilian Amazon and São Paulo . Unfortunately, no adult males were found, only subadults, but the identification is confirmed with several adult females found in the same collections, expanding the distribution of the species to the north and east of Brazil . This species was redescribed by Cadena-Castañeda & Cortés-Torres (2013) , in that same contribution Apotetamenus politus Bruner, 1915 was synonymized under A. clipeatus . The huge population collected in Macapá intrigued us once it is composed only of females. This data suggests that this particular population probably is parthenogenetic. It has been largely postulated that asexual populations are colonization linages, and usually occur where sexual populations are difficult to establish, like isolated or marginal habitats ( Lorenzo-Carballa et al. 2012 ). The sites where this species was collected are predominantly formed by open vegetation or rightly altered forest—all the localities in Amazon region are areas of savanah or highly devasted forest areas ( i.e. , the locality in Paragominas is a bauxite mine). This data suggest that this kind of environment favors the stability of A. clipeatus populations or colonization. Specimens examined and new records.
