Revision of the neotropical spider genus Dyrines (Araneae, Lycosoidea, Trechaleidae)

The genus Dyrines, is revised for the first time since Simon provided the name in 1903 to replace the preoccupied Drances. A female lectotype is designated for the type species, Dyrines striatipes (Simon 1898), which is redescribed and illustrated. The holotype of D. taeniatus Mello-Leitao 1943 is a tiny spiderling and is considered a nomen dubium. Dyrines lineatipes Petrunkevitch 1925 is regarded as a junior synonym of D. striatipes. Dyrines rubriosignatus Mello-Leitao 1943 is transferred to the genus Thaumasia, resulting in Thaumasia rubrosignata (Mello-Leitao 1943b), new combination. Two new species are described and illustrated: D. huanuco from Huanuco, Peru, and D. ducke from Reserva Florestal Adolfo Ducke near Manaus, Brazil.
