The grammatical gender is feminine. Diagnosis . This genus can be distinguished from Paradossenus , its closest related genus, by the presence of prominent and laterally dilated chelicerae ( Fig. 8 ) and the tibia of the palpus dilated at the median portion (VP) ( Fig. 9 ). Description . Carapace low ( Fig. 7 ). Chelicerae glabrous medially, with a lateral projection ( Fig. 8 ). Legs yellowish, with brownish spots dorsally. Abdomen, oval with indistinct pattern ( Fig. 6 ). Anterior and posterior eye row moderately procurved ( Fig. 8 ). ALE the smallest and PLE the largest. Chelicerae with 3 teeth on the promargin of the fang furrow and 3 on the retromargin, being the median the largest. Ventral macrosetae pairs on tibiae: I 4 , II 4 , III 3 , IV 3. Long legs (19.01 to 6.29 long) and straight tarsi. Bulbus of the male palpus without a conspicuous division of the median apophysis ( Fig. 11 ); subtegulum and tegulum conspicuous ( Fig. 11 ). Retrolateral tibial apophysis with two branches (ental ( END ) and ectal (ECD) divisions) ( Figs 10–12 ). Ventrodistal protuberance of palpal tibia prominent ( Fig. 9 ). Distribution . Brazil (Pará) ( Fig. 13 ).
