Philisca ornata

Soto, Eduardo M. & Ramírez, Martín J., 2012, Revision and phylogenetic analysis of the spider genus Philisca Simon (Araneae: Anyphaenidae, Amaurobioidinae) 3443, Zootaxa 3443 (1), pp. 1-65 : 17

The ornata species group

This group includes several species with modified chelicerae in adult males ( Figs 34f–h , 35 , 37 ), and a very homogeneous female epigyne, with a smooth, heart-shaped median field close to the epigastric furrow. Except in P. huapi , the adult males have a projection on the ectal margin of the endites.
