Etymology. The specific name is a noun in apposition referring to the location of the type locality, in the delta of the Amazon River.

Diagnosis. Males differ from those of other species with long endite’s P1, reaching at least the anterior margin of the sternum ( H. harveyi sp. nov., H. erebai sp. nov., H. periclitata sp. nov., H. fannesi sp. nov., H. tallitae sp. nov. and H. platnicki sp. nov.) as follows: from H. harveyi sp. nov. by the relatively shorter endite’s P1 (reaching the anterior margin of sternum, Fig. 25C View FIGURES 25 ; reaching the middle of sternum in H. harveyi sp. nov., Fig. 16A View FIGURES 16 ); from H. fannesi sp. nov. and H. erebai sp. nov. by the straigth tip of endite’s P1 ( Fig. 25C View FIGURES 25 ) (folded ventrally in H. fannesi sp. nov., Fig. 18C View FIGURES 18 ; twisted lateraly in H. erebai sp. nov., Fig. 20C View FIGURES 20 ); from H. periclitata sp. nov. by the curved, not longitudinally oriented endite’s P1 ( Fig. 25C View FIGURES 25 ) (longitudinally oriented in H. periclitata sp. nov., Fig. 23B View FIGURES 23 ); from H. tallitae sp. nov. and H. platnicki sp. nov. by the divergent endite’s P1 ( Fig. 25C View FIGURES 25 ) (convergent in both H. tallitae sp. nov. and H. platnicki sp. nov., Figs 28C View FIGURES 28 , 31B View FIGURES 31 ).
