Arachnologische Mitteilungen / Arachnology Letters 54: 52-58 Karlsruhe, September 2017 New records of spiders (Araneae) from Portugal Jørgen Lissner doi: 10.5431/aramit5412 Abstract. Data about spiders collected in Portugal are presented. Two new species are described, Scotophaeus dolanskyi spec. nov. (Gnaphosidae) and Apostenus crespoi spec. nov. (Liocranidae). Three species are recorded for the first time in Portugal: Dysdera lata Wider, 1834 (Dysderidae), Scotophaeus validus (Lucas, 1846) and Euophrys nigripalpis Simon, 1937 (Salticidae). Illustrations of two rarely illustrated species are also presented: Nigma hortensis (Simon, 1870) (Dictynidae) and Canariphantes zonatus (Simon, 1884) (Linyphiidae). Keywords: Apostenus, Euophrys, Gnaphosidae, Liocranidae, new species, Nigma, Scotophaeus, taxonomy Zusammenfassung. Neue Spinnennachweise (Araneae) aus Portugal. Es werden Daten von Spinnenaufsammlungen aus Portugal vorgestellt. Zwei neue Arten werden beschrieben, Scotophaeus dolanskyi spec. nov. (Gnaphosidae) und Apostenus crespoi spec. nov. (Liocranidae). Drei Arten werden erstmals für Portugal nachgewiesen, Dysdera lata Wider, 1834 (Dysderidae), Scotophaeus validus (Lucas, 1846) und Euophrys nigripalpis Simon, 1937 (Salticidae). Abbildungen zweier weiterer seltenen Arten werden präsentiert, Nigma horten- sis (Simon, 1870) (Dictynidae) und Canariphantes zonatus (Simon, 1884) (Linyphiidae). The spider fauna of Portugal currently includes 812 species (Nentwig et al. 2017) and is still incompletely known. This study deals with a small sample of spiders from mainland Por­ tugal collected by the author, additional small samples were made available by Jan Dolanský from the East Bohemian Museum in Pardubice, Czech Republic and Jorge Alexandre Mota de Almeida from the University of Coimbra, Portugal. Among the combined material (133 species, 239 specimens – see Supplementary File 1) two species are new to science Fig. 1: Nigma hortensis (Simon, 1870): a. epigyne in ventral view (hairs and three others new to Portugal. The aim of this study is to removed); b. vulva in ventral view. Scale bar 0.1 mm describe the new species, to present details of species recorded in Portugal for the first time and to provide illustrations of two rarely illustrated species. Material and methods Spiders were collected by hand, by shaking vegetation or by brushing stones above a tray. Illustrations were created from photos of selected features using a Leica Wild M10 stereo­ microscope fitted with a Leica DFC425 digital camera or a Leica 205 stereomicroscope fitted with a Leica DFC450 di­ gital camera. The microscopes were connected to computers with Leica Application Suite software, Zerene Stacker soft­ Fig. 2: Nigma hortensis (Simon, 1870), photos: a. epigyne in ventral view ware and the vector graphics editor Inkscape.

According to Kovblyuk et al. (2008) D. lata differs from the closely related D. westringi O. Pickard­ Cambridge, 1872 by having the flattened bulbus furnished with 3­7 teeth (D. westringi has no teeth on it). The hitherto western­ most locality for D. lata was Majorca (Bosmans et al. in press) but the new record from the present study extends the known range about 1000 km to the west. The identification was confir­ med by Miquel Arnedo, University of Barcelona, Spain. Scotophaeus dolanskyi Lissner spec. nov. (Gnaphosidae) (Figs 3­5) Etymology.
