Material examined.

Holotype ♀ COSTA RICA, Puntarenas, San Vito, Las Cruces , 8º47’N, 82º58’W, 1000-1300m, 7-19.ii.2007, swept, C. Hansson ( MZLU) . Paratypes (2♀, NHMUK): 1♀ from same locality as holotype but collected 15-16.ii.2006 ; 1♀ COSTA RICA, Puntarenas, Parque Nacional Corcovado, Sirena, 8º29’N, 83º35’W, 5m, 19-20.ii.2004, J.S. Noyes.

Etymology. From the Latin scabiosus = rough, scurfy, referring to the rough sculpture on midlobe of mesosutum and mesoscutellum.
