On the spider genus Spanioplanus (Araneae: Linyphiidae): three new species from Uruguay and Argentina

ABSTRACT

Three new species of the genus Spanioplanus Millidge (Araneae: Linyphiidae) are described: Spanioplanus juru n. sp. (male and female) from riparian forests and psammophilus scrublands in Uruguay, Spanioplanus holmbergi n. sp. (male and female) and Spanioplanus olejniki n. sp. (female) from riparian forests and hilly systems in central-eastern Argentina. Photographs and illustrations of somatic and sexual characters of the species are provided. Furthermore, data of the natural history and a distribution map for these species are presented together with an updated diagnosis of the genus. These findings document a higher species number of this previously monotypic genus and expand its known distribution in South America.
