Araneae North America undescribed species generic placement

Abstract

The number of undescribed Linyphiidae in North America is estimated to range from 200 to 500 species. To further taxonomic knowledge and fill the basic need for species identification, we describe five new species collected in bio-inventories: Agyneta sheffordiana new species, Oryphantes aliquantulus new species, Sisicus volutasilex new species, Tapinocyba cameroni new species and Tapinotorquis yamaskensis, new genus, new species. We provide detailed morphological descriptions of males and females, distribution data and habitat affinities for each species. These new species show different situations for their generic placement, from an obvious assignment to a species-rich genus to the necessity to create a new genus. In attempting to assign Tapinotorquis yamaskensis to a known genus, we discovered that the only North American record of Jacksonella falconeri (Jackson 1908) is a misidentification of Scirites pectinatus (Emerton 1911).
