A new species and new distribution records of Pickeliana (Opiliones: Laniatores: Stygnidae)

Uma nova espécie e novos registros de distribuição para Pickeliana (Opiliones:Laniatores: Stygnidae)

A new species of Pickeliana Mello-Leitão, 1932, P. albimaculata sp. nov., is described from Jussari, Bahia, Brazil. It can be easily distinguished from the already described species by the presence of white spots on mesotergal area I and anal opercle. It is similar to P. pickeli Mello-Leitão, 1932 by the presence of a large, ventro-apical pointed tubercle on femora III-IV. A cladistic analysis was performed adding a new character to the available character matrix, the presence of a large and ventro-apical pointed tubercle on male femur IV. According to this analysis, P. albimaculata sp. nov. is sister species of P. pickeli. Additionally, we present an identification key and an update on the geographical distribution of species of this genus in northeastern Brazil.
