Remarks

The holotype was deposited in the Museu Paraense Emílio Goeldi but has been on loan since 2004 (O.T. Silveira, pers. comm., 2022). Therefore, we could not examine the holotype except for the lowresolution picture available in Zompro (2004b). According to Zompro (2004b), this species is very similar to Arumatia dubia gen. et comb. nov. with which it shares the median segment as long as the metanotum, and the very elongate cerci and basitarsi, traits that can be confirmed from the holotype picture. According to Zompro’s (2004b) description and diagnosis, A. fulgens gen. et comb. nov. differs from A. dubia by the stouter body and the longer subgenital plate reaching the end of tergum X, features that are not visible in the picture. However, both in the description and in the picture, a striking feature

is the much longer cerci than that of other species of Arumatia Ghirotto gen. nov. in comparison with the last terga. Zompro (2004b) also pointed out the black longitudinal dorsal line on the body as a diagnostic feature of A. fulgens , but the female holotype of A. aramatia gen. et sp. nov. and some specimens of A. dubia also present such a line or similar longitudinal markings ( Figs 13A, F , 25 ). Arumatia fulgens is recorded from the seasonal forest of the Cerrado in Estação Ecológica Serra das Araras near Barra do Bugres, Mato Grosso state, Brazil ( Fig. 52 ).
