  A further new species for the genus Ananteris Thorell, 1891 (Scorpiones: Ananteridae) from a poorly prospected region of Brazilian Amazonia Abstract  A new species of the genus Ananteris Thorell, 1891 is described from the region which today defines the ‘Reserva Biológica do Río Trombetas’ in the state of Pará, Brazil. The collection of the unique specimen, presently study, took place previously to the definition of this reserve, in a joint field trip with a team of the Instituto Brasileiro de Desenvolvimento Florestal (IBDF). Ananteris antoni sp. n. is described based on one female specimen collected in a zone of dense humid forest, under death log. With this new description, the number of Ananteris species known for the scorpion fauna of Brazil is now raised to 33. Lourenço W.

 A survey of the spider genus Ischnocolus Ausserer, 1871 (Aranei: Theraphosidae) in Israel, with description of a new species

ABSTRACT

The genus Ischnocolus Ausserer, 1871 is found to include three species represented in Israel: the recently described I. ignoratus Guadanucci et Wendt, 2014, I. meron sp.n. described herein, and an additional congener inhabiting the Negev Desert and known only from a subadult specimen (most likely, belonging to I. jickelii L. Koch, 1875). The new species differs from I. ignoratus as well as from other congeners by a specific configuration of the spermathecae and by integral leg tarsi I–IV lacking the transverse suture. Regarding the type series of I. ignoratus, a controversial information concering the collection data is discussed in detail. Ischnocolus meron sp.n. and I. ignoratus are diagnosed, depicted and (re)described; the data on their ecology and distribution are also provided.
