Remarks.

Lycosa michaelseni was transferred by Mello-Leitão (1947: 263) to Alopecosa , and than declared a nomen dubium by Casanueva (1980: 54); "La descripción original dada por Simon define caracteres que en su mayor parte coinciden con las de otras especies del género Lycosa . La falta de material tipo (probablemente perdido) no permite reconocer a esta especie". The other specimen mentioned by Simon from Puerto Toro was not found in the ZMH collection.

Description.

Female (lectotype). Total length: 10.97; cephalothorax length: 4.73; cephalothorax width: 3.48. COLORATION: (from original description, translated from Latin): "cephalothorax with black forehead, covered by yellow-grayish hairs, with a submarginal sinuous line on both sides. Abdomen black with dark brown hair, intermingled with a few white hairs, longitudinal lanceolate concolor band, posteriorly with spots in two rows, scarcely marked".

CEPHALOTHORAX: Longer than wide, not elevated (Fig. 10A). Chelicerae with two promarginal and two retromarginal teeth. EYES: AME larger than ALE, AER straight in anterior view. ABDOMEN: Oval (Fig. 10A). LEGS: Tibia I with three pairs of ventral spines (2-2-2). GENITALIA: Short, inverted T-shaped median septum; anterior pockets shallow (Fig. 10B, C).

Male. Unknown.

Distribution.

Chile: Punta Arenas.

Note.

Aleopcosa is a large genus of wolf spiders with currently 161 desribed species that are distributed in Eurasia (75% of species), and a few (9%) with a Holarctic or Palearctic distribution (Blagoev & Dondale 2014). Only seven species occur in South America (Venezuela, Ecuador and Argentina) and probably do not belong to that genus but we retain this species in Alopectosa , emphasizing the need for revision.
