A new species of spider of the genus Sadala Simon, 1880 (Araneae, Sparassidae) from the Yasuni Biosphere Reserve, Amazonian lowlands of Ecuador

We describe a new species of giant crab spider of the genus Sadala Simon, 1880 collected in Lowland Evergreen rainforests at the Tiputini Biodiversity Station, Yasuni Biosphere Reserve, Amazonian Ecuador. This new species corresponds to the first record of the genus from Ecuador. Females of the new...

Description
Summary:We describe a new species of giant crab spider of the genus Sadala Simon, 1880 collected in Lowland Evergreen rainforests at the Tiputini Biodiversity Station, Yasuni Biosphere Reserve, Amazonian Ecuador. This new species corresponds to the first record of the genus from Ecuador. Females of the new species of Sadala are similar to S. punicea and S. nanay, by having the epigyne with a median septum diamond‐shaped posteriorly. The new species is easily distinguished from S. punicea and S. nanay by having relatively straight anterior lateral margins of the median septum. This study increases to 10 the number of described species of Sadala. Resumen Describimos una nueva especie de araña cangrejo gigante del género Sadala Simon, 1880 colectada en Bosque Lluvioso Siempreverde de Tierras Bajas en la Estación de Biodiversidad Tiputini, Reserva de la Biósfera Yasuní, Amazonía del Ecuador. Esta nueva especie corresponde al primer registro del género en Ecuador. Las hembras de la nueva especie de Sadala se diferencian de todos sus congéneres, excepto S. punicea y S. nanay, por un septo medio del epiginio con forma de diamante posteriormente. La nueva especie se diferencia fácilmente de S. punicea y S. nanay por tener los bordes anterolaterales del septo medio relativamente más rectos. Este estudio incrementa a diez el número de especies descritas de Sadala. The first species of spider of the genus Sadala is described from Ecuador. The new species was discovered at the Tiputini Biodiversity Station, a research station in the Yasuni Biosphere Reserve, Amazonian lowlands of Ecuador.
