Acontista aurantiaca Burmeister, 1838: 531 .

Type locality. Brazil (Burmeister 1838) .

Records. CeNak: ♂, 16.IX.1973, leg. H. W. Koepcke. SMNK: ♀, 230 m, 21.IX.–08.X.2012, leg. K. Schönitzer (SMNK-Mant 12828, ex. ZSM). ZSM: ♂, 230 m, lux, V.2015, leg. E. Diller (Fig. 84); ♀, 220 m, 21.IX.–04.X.2004, lux, leg. K. Schönitzer, T. Kothe, M. Breitsameter, O. Conle & F. Hennemann (Fig. 85) .

Distribution. Brazil, Ecuador, Peru.

Remarks. This species is not identical with the SE Brazilian A. concinna, as suspected by Kirby (1904) and Heitzmann-Fontenelle (1965). Our specimens agree with the ones from the MRSN identified by E. Giglio-Tos as A. aurantiaca . This species is very common in Peru and Ecuador, but has often been recorded as A. concinna in the past (see also Rivera & Vergara-Cobián 2017).

The nymphs of this species exhibit morphological and behavioral ant mimicry (Fig. 147). Early instars use several sympatric species of the genus Pseudomyrmex as a model (see also Salazar 2003a), while later instars resemble Ectatomma tuberculatum (pers. obs.).
