Types.

Holotype ♂ and paratype ♀ (MMUM), paratypes 2♂ (ZMUI), 14 ♂ 4juv (ZMMU), IRAN, Fars Prov., Shiraz City, nearby Qur’an Gate, 29°38'08"N, 52°33'42"E, leaf and pine needle litter in small park, 19 Dec 2013 (Y.M. Marusik).

Etymology.

The specific name is a patronym in honour of the well-known Iranian arachnologist, Professor Majid Moradmand (Isfahan).

Diagnosis.

The new species differs from P. bosmansi sp. n. by the less intense colouration of the male (cf. Figs 1c & 1d). Males of this species can be distinguished by the larger palp (cf. Figs 7 a–c & 7 d–f and 10b & 10d), horizontal orientation of embolic base anterior edge and posterior edge of the basal part of the embolus (vs. inclined (cf. Figs 10 b’ and 10 d’)) and relatively longer tibia - length/width ratio approx. 2 (vs. short er, ratio ca. 1.5). Females of P. moradmandi sp. n. can be distinguished from P. bosmansi sp. n. by the shape of the epigyne: epigynal fovea pentagonal (vs. oval) with distinct posterior notch (vs. lacking), anterior position of hyaline receptacles (vs. sclerotised receptacle located anteriorly), anteriorly directed loop of copulatory duct (vs. posteriorly). Porrhoclubiona moradmandi sp. n. is very similar to P. leucaspis by the abdominal pattern, palp shape, and particularly by having a filamentous extension (Fl) of the tibial apophysis, although the female differs by the shape of the copulatory ducts and receptacle proportions (cf. Fig. 8 a–c and Fig. 9b and Bosmans et al. 2017: figs 45-51).

Description.

Male. Total length 3.38-4.67. Carapace 1.70-2.17 long, 1.17-1.64 wide. Abdomen 1.57-2.50 long, 1.0-1.57 wide. Carapace yellow to light brown without pattern, Labium, maxillae and chelicerae light brown. Sternum yellow. Chelicerae with one promarginal, retromarginal teeth absent.

Leg lengths (paratype with carapace 2.17 long)

Leg spination

Abdomen yellow with greyish V-shaped stripes (indistinct due to poor condition of the specimen) dorsally.

Palp as in Figs 4 d–f, 5b, d, e, 7 a–c, 9d, 10b. Tibial apophysis subtriangular, wider than long; tip with filamentous extension (Fl); anterior edge of cymbium rounded, with one distinct macroseta; modified setae of cymbial brush dense and long almost ½ of cymbial length; basal part of embolus ca. ½ of embolus base height, anterior edge of embolic base and posterior edge of basal part of embolus horizontal; base of embolus shorter than anterior part of tegulum.

Female. Total length 4.08. Carapace 1.93 long, 1.29 wide. Abdomen 2.07 long, 1.33 wide.

Coloration as in males. Chelicerae with 3 or 4 promarginal and 4 retromarginal teeth.

Leg lengths

Leg spination

Epigyne as in Figs 8 a–c, 9b. Fovea pentagonal with deep posterior notch; translucent receptacles spaced by less than radius in intact epigyne; copulatory duct well distinct in ventral view; hyaline receptacles located anteriorly from the sclerotised receptacles; loop of copulatory duct directed anteriorly; mesal part of copulatory ducts spaced by more than 3 times their diameters.

Distribution.

It is known from the type locality only.
