On the genus Pachygnatha (Araneae, Tetragnathidae) in the Albertine Rift of Burundi, with the description of three new species

Abstract

Three new species of Pachygnatha, P. bispiralis sp. nov., P. intermedia sp. nov. and P. ventricosa sp. nov., are described from forest areas in western Burundi. The presence of P. procincta Bosmans & Bosselaers, 1994 in Burundi confirms its very wide distribution spanning most of Africa. Pachygnatha appears to be an important element of the afromontane spider fauna.
