Description of the females of the spiders Plesiophantes joosti Heimer, 1981 and Araeoncus clavatus Tanasevitch, 1987 from Turkey (Araneae: Linyphiidae)

Plesiophantes joosti Heimer, 1981 and Araeoncus clavatus Tanasevitch, 1987 were originally described on the basis of single male specimens from Georgia and Armenia, respectively. The females of both species have not yet been described. We redescribe P. joosti based on a series of new specimens including 2 adult males and 6 adult females collected from two localities in the Artvin province of Turkey. A. clavants is redescribed based on 3 adult males and 1 adult female collected from two localities in the Artvin and Ardahan provinces of Turkey. Both species are new records for the spider fauna of Turkey. Drawings of characteristic features, the female genitalia and the male palpal organs arc presented.
