( Figs. 65–67, Map 1)

Miriatra chalazombra Günther, 1939: 268 . Holotype. Female. BRAZIL, Pará. Depository: Polish Academy of Science , Museum of the Institute of Zoology (MZPW).

Material examined. Female. BRAZIL, Pará, Novo Progresso; Serra do Cachimbo , Campo de Provas Brigadeiro Veloso , Ponto 2— Rio Formiga , mata ciliar [riparian forest], 09°22’24”S, 55°01’10”W; [420 m; close to Mato Grosso State border]; 07-17.IX.2003; Pitfall ( MPEG) .

Remarks. The holotype specimen of this species was originally described from Pará, and the paratype from Santarém (the same state), Brazil. Between both female specimens, the most notable difference is that the holotype has more pronounced undulations on the median carina of the pronotum, compared with the paratype ( Fig. 65). Here, an additional female from the southern part of Pará state near the border with Mato Grosso is recorded (Map 1), which matches the morphology of the species’ paratype, with lighter tones, possibly due to being preserved in alcohol for a long time ( Figs. 66, 67).
