  An Overlooked Species of Enigmatic Wolf Spider (Araneae: Lycosidae) Clarifies the Mysterious Distribution of its Sibling Abstract Several wolf spiders exhibit a peculiar geographical distribution. One good example of this is Pardosa aenigmatica Tongiorgi, 1966, recently recognized in Italy and the Middle East but missing in the Balkans. A comparison of populations from the disjunctive areas revealed that they would be better described as two distinct species. As a result, here we describe Pardosa sepidehae sp. nov. The paper includes detailed descriptions and comparative illustrations of male and female copulatory organs for the newly discovered species and P. aenigmatica. Pardosa sepidehae sp. nov. is distributed in the Middle East, whereas P. aenigmatica remains endemic to the Apennine Peninsula.

Description of a new species of Chaco Tullgren, 1905 (Araneae: Mygalomorphae: Pycnothelidae) from Argentina and the southernmost record of the genus

Abstract

A new species of Chaco Tullgren, 1905 was discovered and is formally described. Chaco aoni sp. nov. from the Santa Cruz River in Santa Cruz Province, Argentina, is the southernmost recorded species of this genus. The new species is diagnosed on the basis of the morphology of the palpal organ and tibial apophysis of males and the shape of the spermathecae of females. A cladistic analysis was carried out based on an already published morphological matrix, which now also includes the new species. This new species is part of a monophyletic group including also Chaco tingua Indicatti, Folly-Ramos, Vargas, Lucas & Brescovit, 2015, C. tecka Goloboff, 1995, C. sanjuanina Goloboff, 1995, C. patagonica Goloboff, 1995 and C. ansilta Ferretti, 2014.
