Clubiona tripunctata Nicolet, 1849: 138 (2 female syntypes from Chile, no specific locality, in MHNP 4219 , not reexamined).

Liparotoma pardalis Mello-Leitão, 1943: 405 (immature holotype from Chile, Santiago, J. Carbalho coll., in MNRJ, not reexamined). Synonymized by Ramírez, 1993.

Liparotoma tripunctatum: Ramírez, 1993: 198 ; 2003: 189–191.

Philisca tripunctata: Ramírez, 2003: 189 .

Diagnosis: Distinguished from other Philisca by having only one tooth on the retromargin of the chelicerae and by the dark, rectangular ventral patch on the opistosoma ( Fig. 1a ) ( Ramírez 1993: fig. 16). Male chelicerae not modified ( Fig. 34b ).

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

Distribution: Chile, from Choapa province to Cabo de Hornos. Argentina, from Neuquén to Tierra del Fuego provinces ( Fig. 38b ).

Variability: Spines in male and female: IV: femur p 0, r d1ap.
