Specimens Examined. Paratypes: COSTA RICA: 1 male, Cartago Province, Pacayas, 1600 m, 09°55'N, 083°48'W, (C. Werckele)(AMNH) ADP44192; 1 female, San Jose Province, Estacíon Zurqui, 500 meters before the tunnel, 1600 m, LN226800,535200, April, (G. Maass)(USNM) ADP100513 .

Notes. Remarkably, this species has remained unnoticed. I suspect it lives among mossy boulders at the steep sunny edges of mountain torrents, a slippery and perhaps dangerous place to collect.
