Dysderocrates tanatmisi sp. n., a new spider species from Turkey (Araneae, Dysderidae)

* Correspondence: karakasgzm@gmail.com Dysderocrates Deeleman-Reinhold & Deeleman, 1988, belonging to the family Dysderidae and subfamily Dysderinae, is represented by six extant species. Three species, D. egregius (Kulczyński, 1897), D. silvestris Deeleman-Reinhold, 1988, and D. storkani (Kratochvíl, 1935), are scattered in the Balkans and Eastern Europe, while D. gasparoi Deeleman-Reinhold, 1988 and D. marani (Kratochvíl, 1937) are found on the islands of Corfu and Crete, respectively, and D. regina is found in Turkey. There is no record of the species from southern Turkey or the Caucasus (Bayram et al., 2017; WSC, 2017). The aim of this short communication is to describe a new species of Dysderocrates from the Mediterranean region of Turkey. The specimens were collected from Antalya Province, in the Mediterranean region of Turkey, and preserved in 70% ethanol and deposited in the Anadolu University Zoology Museum. Digital images of the copulatory organs were obtained using a Leica DFC295 digital camera attached to a Leica S8AP0 stereomicroscope. Five to 15 photographs were taken in different focal planes and combined using CombineZP image stacking software. All measurements were taken in millimeters. Terminology for the body measurements followed Chatzaki and Arnedo (2006). Terminology for the copulatory organs was adapted from Deeleman-Reinhold (1988). The abbreviations used in the text are as follows: Carapace and abdomen: AL, abdominal length; CL, carapace length; CWmax, maximum carapace width; CWmin, minimum carapace width. Eyes: AME, anterior median eyes; PLE, posterior lateral eyes; PME, posterior median eyes; AMEd, diameter of anterior median eyes; PLEd, diameter of posterior lateral eyes; PMEd, diameter of posterior median eyes. Chelicera: ChF, length of cheliceral fang; ChG, length of cheliceral groove; ChL, total length of chelicera (lateral external view). Legs: Ta, tarsus; Me, metatarsus, Ti, tibia; Pa, patella; Fe, femur; C, coxa; D, dorsal; Pl, p rolateral; Rl, retrolateral; Pv, proventral; Rv, retroventral; V, ventral. Taxonomy Genus Dysderocrates Deeleman-Reinhold & Deeleman, 1988 Type species: Harpactocrates storkani Kratochvíl, 1935 Dysderocrates tanatmisi sp. n. Figures 1 and 2. Material Examined. Holotype: 1 ♂ (AUZM), Turkey, Antalya Province, Elmalı District, Göltarla village (36°34ʹ38ʺN 29°55ʹ49ʺE), Cedrus libani A.Rich. forest, under stones, a.s. l. 1065 m, 24 December 2015, Leg. K.B. Kunt & E.A. Yağmur — Paratypes: 1 ♂, 3 ♀ (AUZM), same data as holotype. Etymology: The new species is dedicated to the Turkish entomologist Mustafa Tanatmış, a respected colleague of the authors. Diagnosis. Dysderocrates tanatmisi sp. n. is easily distinguished from any other species of Dysderocrates by a pear-shaped bulb, crescent-shaped embolus, and flat, spoon-like apophysis. Bulbs of D. egregius, D. marani, and D. storkani are flatter and more cylindrical than that of D. tanatmisi sp. n. in general structure. Embolar apophysis is present in D. egregius, D. silvestris, and D. storkani; it is flat and scalloped; however, there is no embolar apophysis in D. tanatmisi sp. n. In all these species and in D. gasparoi, the apex of the apophysis is turned to the distal tip while the D. tanatmisi sp. n. is turned to the bulb, overly curved. Abstract: A new species, Dysderocrates tanatmisi sp. n. , is described on the basis of both sexes from the Mediterranean region of Turkey. Herein, we present the morphological and diagnostic characters and illustrations of the genitalia of both the male and female members of this species.
