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.

The embolus is very thin, long, curved, and dagger-shaped compared to other species. Female vulva resembles that of D. regina also known from Turkey, but the spermatheca is longer in D. tanatmisi sp. n. and has a different form. Likewise, the spermatheca of D. tanatmisi sp. n. is easily separated from D. marani and D. storkani by shape.

Description of Holotype ♂: Medium-sized dysderid spiders. Carapace dark brown head and gradually lighter towards thorax. Fovea longitudinal and distinct. Six welldeveloped eyes. Of these, posterior eyes are close to each other and relatively aligned at the same level. Anterior eyes are localized close to and forming a transverse row with posterior lateral eyes, and distant from each other. Chelicera, gnatho-coxae, and labium are brown. Four cheliceral teeth, in two lines, three promarginal teeth, the one located in the base is largest, and one retromarginal tooth, close to the base and considerably smaller than the others ( Figure 1A ). Sternum is brown to light brown towards posterior. Legs are yellowish-brown. Abdomen is bulgy and grayish-brown.

Bulb pyriform. Embolus is connected to the distal tip of the bulb making a 45° angle and lies above a robust chitinized embolar roof directed posteriorly. It is crescent-shaped and the tip is directed prolaterally. A flat, spoonshaped apophysis with the tip directed retrolaterally lies on the counter side of the connection between embolar roof and bulb.

Description of paratype ♀: Females generally have the same somatic characters as the males.There is no important decisive detail except expected size differences and that their females are darker than males.

All parts of vulva are strongly sclerotized. Spermatheca is planar and tips are directed posteriorly on the both sides. Dorsal arch parenthesis shaped. The width is the same as in spermatheca and slightly longer. Transversal bar long, bracket shaped. The tips are directed posteriorly on both sides. Posterior diverticulum has a membranous structure and is indistinct.
