Adelomyrmex striatus Fernández, 2003: 29 , figs. 37, 74. Holotype worker: Brazil, Amazonas, Igarapé Marianil, R. Branco, Rod. Km 24 NE Manaus, 22.viii.62 (W.L. Brown Jr. leg. M-13) [MZSP] (image of paratype examined).

Geographic range. Brazil (Amazonas), Ecuador, Peru.

Comments. I received from P. S. Ward a series of three workers and one queen from a single Winkler sample from Peru (Loreto, 15km WSW Yurimaguas, 5°59'S, 76°13'W, 200m, PSW8701) that showed strong variation among the workers. One worker was identical to images of the Manaus paratype, with sharp spiniform teeth on the median clypeal lobe and regular costate sculpture on the petiolar and postpetiolar nodes. In contrast, the other two workers and the queen had less pronounced teeth on the median clypeal lobe, and the petiolar and postpetiolar nodes were smooth and shiny. Also, on these latter specimens, the facial costae were somewhat thinner and less regular. I also received a worker from Ecuador (Napo, Jatun Sacha, 1°04'S, 77°37'W, 400m, PSW11364) that was similar to the Manaus paratype.
