MATERIAL EXAMINED.

Type material. Holotype E: COSTA RICA, Guanacaste, Guanacaste NP, Estacion Cacao , 950-1200m, 13.ii.1995 (L. Masner) . Holotype in CNC .

COMMENTS. The unusually long funicle segments and relatively deep, elongate scrobes suggest that this species may be misplaced in Psyllaephagus .
