Type dataEdit

Goniosoma dentipes: ♂ holotype (MNHN, or JSPC?) from BRAZIL, without further locality data. Goniosoma grossum: ♀ holotype, (JSPC); “syntypes” [= paratypes] (ZMB 928a-b) from BRAZIL, without further locality data. Progoniosoma cruciferum: ♀ holotype (MNRJ 1453), from BRAZIL, Rio de Janeiro, Rio de Janeiro: Corcovado. Glyptogoniosoma perditum: holotype (MNRJ 42705), from BRAZIL, Minas Gerais, Paraopeba (probably mistaken). Progoniosoma tijuca: ♀ holotype (SMF RII 1342/30), from BRAZIL, Rio de Janeiro, Rio de Janeiro: Tijuca.

DiagnosisEdit

By occasion of their review, DaSilva & Gnaspini (2010) [1] did not present a diagnosis for this species, but they did make a remark:

"Goniosoma ensifer is very similar to G. dentipes and they are sympatric. They can be distinguished by the higher development of some structures in G. ensifer, such as the very large retrolateral apophysis of coxa IV and very curved femur IV, for example. Since only a few specimens of G. ensifer were available for study and since no specimen of G. dentipes that we examined showed the same pattern as G. ensifer, we have decided to keep the species separate, although a future and more detailed analysis may lead to the conclusion of the synonymy."
