Updates on Berlandiella (Araneae: Philodromidae): a new species, description of the male of B. querencia and new diagnosis for the genus

Berlandiella Mello-Leitão, 1929 is currently composed of six Neotropical species, of which Berlandiella querencia Lise & Silva, 2011 is known only from female specimens; the other species of the genus were described based on both males and females. In this paper, we describe and illustrate Berlandiella zabele sp. nov., based on a few individuals collected in Sete Cidades National Park, Piracuruca and Brasileira, state of Piauí, Brazil. We illustrate and describe the previously unknown male of B. querencia, based on a specimen collected from Reserva Mocambo, Belém, state of Pará, Brazil. The taxa described herein have scopula in the tarsi and metatarsi, and the males have a cymbial process, characters recorded for the first time for the genus. Additionally, we present an updated diagnosis for Berlandiella.
