Figs 1A–B , 2A–B , 3A‒C Type material. Holotype ♁ ( ZMUT ), IRAN : Kohgiluyeh & Boyer-Ahmad Province : Gachsaran , Gakal Cave , 1100 m , 30°18'44.0"N , 51°09'28.0"E , XI.2017 ( M.J. Malek Hosseini ) . Paratypes : 1♁ 1♀ ( ZMUT ), same data as for the holotype . Etymology. The specific epithet is a Latin adjective, referring to the pale coloration of both sexes of this species. Diagnosis. This species is most similar to T . alamto from western Iran , from which it differs by the angled anterior edge of the conductor ( vs . roundly bent), the bulb (from posterior edge to embolus) being longer than it is wide ( vs . as long as wide), the embolus base positioned at 8:30 o’clock ( vs . 9:30), the roundly bent embolus ( vs . the embolus bent at right angle), the relatively long conductor (cf. Fig. 2A and 2C ), and the converging receptacles forming a right angle ( vs . obtuse; cf. Fig. 3B and Zamani et al . 2018 : fig. 11). Description. Male ( Holotype ). Habitus as in Fig. 1B .

FIGURE 5. Male palp of Dysdera elamana sp. n. A retrolateral view; B dorsal view; C ventral view. Scale bars: 0.2 mm. Abbreviation: Ac— anterior crest, Mc— median crest, Vc— ventral crest. Comment. This is the first known Iranian agelenid species displaying a certain level troglomorphism (i.e., elongated appendages and depigmentation). Distribution. Known only from the type locality in Gakal Cave ( Fig. 15C ), Kohgiluyeh & Boyer-Ahmad Province, southwestern Iran ( Fig. 17 ).
