Material examined. Holotype: male, Peru: Pasco, 3km N Oxapampa, 1700m, 10°33.20'S , 75°25.55'W , 21 Oct 2002, C.H. Dietrich, merc vapor light, 02 -31- 1 (INHS). Paratypes: 3 males, same data as holotype. Etymology. This name is based on the style with a long apophysis. Remarks. This species is similar to Parandanus paracruciatus in color pattern but differs from this and other species by its very long style apophysis.
