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 : 12-14

Philisca hyadesi (Simon)

Figs 5 , 34d , 38d

Liparotoma hyadesi Simon, 1884: 138 (female holotype from Cabo de Hornos, in MHNP, not reexamined). Ramírez, 1993: 201.

Philisca hyadesi: Ramírez, 2003: 186 .

Diagnosis: Resembles P. doilu by the low cephalic area ( Ramírez 1993: fig. 22), the transversely wrinkled median field of the epigyne advanced from the epigastric furrow ( Fig. 5b ), and the elongate paramedian apophysis ( Fig. 5d, e ). It can be distinguished by the wider sternum (width more than 65% of the sternum length).

Description: Male and female described in Ramírez (1993, 2003).

Distribution: Southern forests in Chile, from Cautín prov., and Argentina, from Neuquén to Cabo de Hornos ( Fig. 38d ). In Chile, two isolated records from Valparaíso (Quintay; Ramírez, 2003) and Petorca (Cuesta El Melón; Ramírez, 1993) might indicate an interesting relict, or a mislabelling ( Ramirez 2003).

Berkeley, 1 female ( CASENT 9039140 ) , 2 females and 1 immature ( CASENT 9039125 ) . Región XIV (de los Ríos): Valdivia Prov.: Reserva Costera Valdiviana , 15.03 km WSW Corral, S39º59.638’ W73º35.113’, elev. ca. 335m, general collecting in native forest dominated by Nothofagus , 26.II.2008, H. Wood, C. Griswold CL–011, 1 female ( CASENT 9030009 ) .

Material re-examined: ARGENTINA: Neuquén: Puerto Blest, Laguna los Cantaros , 7–20.I.2000, L. Lopardo, A. Quaglino, 4 females ( MACN-Ar 14807 ) ; P.N. Nahuel Huapi, Lago Espejo , 21.I.1985, M.
