Type species. Naderiore carajas sp. nov., by monotypy.

Diagnosis. Naderiore most closely resembles Adisomus Cokendolpher & Reddell, 2000, Piaroa Villarreal, Tourinho & Giupponi, 2008 and Calima Moreno-González & Villarreal, 2012 , sharing with them the following characters: (1) four-segmented female flagellum, (2) male flagellum sub-rhomboidal shaped (only some Piaroa species), (3) absence of dorsal eminences on the male flagellum, (3) absence of gonopod in the spermathecae, (4) absence of posterodorsal abdominal process on the segment XII, and (5) absence of a single well developed accessory teeth in the chelicerae. Naderiore differs from all of them by the presence of two pairs of spermathecal lobes almost straight with distinct slightly marked terminal bulbs ( Fig. 17 ), chitinized arch with an anteriorly notched LT ( Fig. 17 ), male heteromorphic pedipalp patella armed with a ventral spur ( Figs. 14-15 ), and the setae Dm 3 modified as macrosetae on the male flagellum ( Fig. 1 ). It may also be differentiated from Calima by the presence of chitinized arch in the spermathecae ( Fig. 17 ) and Vm 2 in both sexes flagella ( Figs. 1-3 , 7-8 ).

Etymology.“ Naderiore ” is a noun from Carajás indigenous people that means “brother”. Gender masculine.

Remarks.A significant character of the genus is the presence of Dm 3 modified as macrosetae in the male flagellum ( Fig. 1 ), a unique condition among the Neotropical species of Hubbardiinae .
