A new species of spider (Araneae, Linyphiidae, Islandiana) from a southern Indiana cave

Abstract

The genus Islandiana (Araneae, Linyphiidae) was erected by Braendegaard in 1932 and is comprised of 14 species, most of which are native to North America. Herein we add a 15th species, Islandiana lewisi sp. n., from southern Indiana, USA. This species resembles both I. flavoides Ivie, 1965 and I. cavealis Ivie, 1965, the latter of which is geographically-close.
