Holotype male: outside of Cueva Aktun Kan, Colonia del Bosque, Santa Elena de la Cruz, Petén, Guatemala, 16°54'10.9"N, 89°53'44.3"W, ~164 m, 1.I.2008, S. Crews, under bark of large tree, SCC08_001 (EME sel_867).

GUATEMALA: Petén, Santa Elena de la Cruz, Colonia del Bosque, other entrance of Cueva Aktun Kan, 16°54'15.7" N, 89°53'54.6" W, ~142 m, 31.XII.2007, S. Crews, under bark, SCC07_060, 2 imm. (CAS sel_865, 866).
The name of this species comes from a combination of words, Petén, referring to the type locality, and the word for spider, ajtoy, in Mopan Mayan, the language indigenous to the people of the region of the type locality. It is to be treated as a noun in apposition.
Males can be separated from all other species by the large, hooked MA, and the small simple RTA (Figs 77–78). Females unknown.
