Descripción
Two new species of Plesiopelma Pocock, 1901 from northern Argentina are described and diagnosed based on males and habitat descriptions are presented. Males of Plesiopelma paganoi sp. nov. differ from most of species by the absence of spiniform setae on the retrolateral face of cymbium, aspect of the palpal bulb. Plesiopelma aspidosperma sp. nov. differs from most species of the genus by the presence of spiniform setae on the retrolateral face of cymbium and it can be distinguished from P. myodes Pocock, 1901, P. longisternale (Schiapelli & Gerschman, 1942) and P. rectimanum (Mello-Leitão, 1923) by the separated palpal bulb keels and basal nodule of metatarsus I very developed. It differs from P. minense (Mello-Leitão, 1943) by the shape of the palpal bulb and basal nodule on metatarsus I well developed. Specimens were captured in Salta province, Argentina, inhabiting high cloud forests of Yungas eco-region.
Dos nuevas especies de Plesiopelma Pocock, 1901 del norte de Argentina son diferenciadas y se describen en base a ejemplares machos y se presentan descripciones de los ambientes. Machos de Plesiopelma paganoi sp. nov. difieren de la mayoría de las especies por la ausencia de setas espiniformes en la cara retrolateral del cymbium, por la forma del órgano palpar. Plesiopelma aspidosperma sp. nov. difiere del resto de las especies por la presencia de setas espiniformes en la cara retrolateral del cymbium y se distingue de P. myodes Pocock, 1901, P. longisternale (Schiapelli & Gerschman, 1942) y P. rectimanum (Mello-Leitão, 1923) por las quillas del bulbo separadas y el nódulo basal del metatarso I muy desarrollado. Se diferencia de P. minense (Mello-Leitão, 1943) por la forma del órgano palpar y el nódulo basal del metatarso I desarrollado. Los especímenes se capturaron en la provincia de Salta, Argentina, habitando nuboselvas de altura en la eco-región de Yungas.
