A revision of the palpimanid spiders of the new subfamily Otiothopinae (Araneae, Palpimandae). American Museum novitates ; no. 2562

Abstract

"The subfamily Otiothopinae is erected for those palpimanids whose males have palpi consisting of only a bulb and embolus, without accessory terminal sclerites. Three genera (Otiothops MacLeay, Anisaedus Simon, and Fernandezina Birabén), restricted to the New World, are recognized. Compsopus Tullgren and Iheringia Keyserling are placed as junior synonyms of Anisaedus and Otiothops, respectively. The African genus Diaphorocellus Simon is removed from the synonymy of Iheringia and placed in the Chediminae. The possible phylogeny and zoogeographic history of the genera and species groups of Otiothopinae are discussed. Eleven new species are described: Otiothops loris from Peru; O. inflatus from Paraguay; O. baculus, facis, clarus, and contus from Brazil; O. intortus from Trinidad; Anisaedus pellucidas from Chile; and Fernandezina pelta, divisa, and acuta from Brazil. Four specific names are newly synonymized: Otiothops lapidicola Simon and O. carpenteri Chickerling, both with O. oblongus Simon; O. casobus Chickering with O. pentucus Chickering; and Anisaedus argentinus Mello-Leitão with A. rufus (Tullgren). The homonym Otiothops amazonicus Mello-Leitão is renamed O. pilleus. The male of O. amazonicus Simon and the females of O. calcaratus Mello-Leitão and O. whitticki Mello-Leitão are described for the first time"--P. [1].
