Seven new species of Psechrus and additional taxonomic contributions to the knowledge of the spider family Psechridae (Araneae)

Abstract

Seven new Psechrus species are described from South East Asia: P. arietinus sp. nov.(♂♀, Vietnam), P. insulanus sp. nov.(♂, Thailand), P. ampullaceus sp. nov.(♂♀, Vietnam), P. omistes sp. nov.(♂, Indonesia, Sumatra), P. quasillus sp. nov.(♂♀, Malaysia, Borneo), P. huberi sp. nov.(♀, Philippines), and P. wade sp. nov.(♂, Philippines). For the following species, new records are listed and intraspecific variation is discussed and illustrated: P. libelti Kulczyński, 1908, P. norops Bayer, 2012, P. rani Wang & Yin, 2001, P. khammouan Jäger, 2007, P. luangprabang Jäger, 2007, P. jaegeri Bayer, 2012, P. obtectus Bayer, 2012, P. kenting Yoshida, 2009 and P. crepido Bayer, 2012, and Fecenia protensa Thorell, 1891. The latter species is recorded from Vietnam for the first time. P. norops, P. libelti and an unidentified Psechrus species from Baluno, Mindanao are for the first time characterised and illustrated by their pre-epigynes and pre-vulvae.

An unusual new wolf spider species from the Erg Chebbi Desert in Morocco (Araneae: Lycosidae: Evippinae)

“…His diagnoses for many genera and also for many species were not coherent. Roewer (1959Roewer ( , 1960 only gave minor consideration to common structural patterns of the copulatory organs, many of which nowadays are considered extremely important for taxonomic research (Alderweireldt 1992(Alderweireldt , 1996(Alderweireldt , 1999Bayer 2012Bayer , 2014Bayer & Schonhofer 2013;Jager 2014;Duperre 2015). Furthermore, Roewer (1959Roewer ( , 1960 included highly variable somatic characters in his diagnoses.…”

Spiders from Vietnam (Arachnida: Aranei): new species and records

“…It was recently reviewed by Ono et al [2012], who listed 456 spider species. Since that time, some 50 additional spider species have been added to or described from Vietnam in the following families: Atypidae, one species [Zha et al, 2012]; Hahniidae, five species [Zhang et al, 2013]; Mysmenidae, three species [Lin, Li, 2014]; Nemesiidae, one species [Li, Zonstein, 2015]; Oonopidae, two species [Tong, Li, 2013]; Pholcidae, 27 species [Yao et al, 2012[Yao et al, , 2015; Psechridae, four species [Bayer, 2014]; Sparassidae, three species [Jäger, 2008;Eusemann, Jäger, 2009;Pham, 2012]; Thomisidae, one species [Benjamin, 2013]; and Zodariidae, three species [Dankittipakul et al, 2012]. Thus, to date a total of 506 ABSTRACT.…”
