Figs 4A–K , 5 Type material . IRAN : Hormozgan Province : Holotype male ( ZMMU ), 75 km N of Bandar Abbas , Siahu , 27°33’N , 55°38’E , 600–700 m a.s.l. , Alireza Zamani leg. 30.1.2020 . Paratypes . 2 males , 1 juvenile ( RCNS ), with same data as for holotype . Etymology . Named after Airyaman, the Persian divinity of friendship and healing; name in the genitive case. Diagnosis . The new species is most similar to H. chemerisi Staręga & Snegovaya, 2008 , different from it by the following characteristics: smaller body size [ H. chemerisi body length 5.5, width 3.2 vs. 3.4, 2.2], large group of about 30 black-tipped smaller denticles in front of the eye mound [about 15 medium-sized denticles in H. chemerisi ]. Description . Male ( holotype ). Body medium-sized (length 3.4, width 2.2), dorsally covered with small dark denticles, those closer to eye mound arranged in regular transverse rows, the rest scattered randomly ( Fig. 4A ). Eye mound low ( Figs 4A–B ), with 7–8 dark denticles and with a large group of black-tipped denticles anteriorly, each with a small bristle basally. Dorsal side of body sand-colored and with a slightly darker saddle pattern; limbs also sandy in color, with small darkened areas on surface. Legs long (Body Leg Index = 1.36); 1st pair considerably thickened ( Fig. 4A ), surface of its segments with longitudinal rows of dark teeth ( Figs 4A–D ). Ventral surface of metatarsi with densely packed brushes of short bristles, like those in H. chemerisi ( Snegovaya & Cokendolpher 2021 : fig. 1E). Lengths of leg segments: I - 3.0+1.0+2.5+3.1+5.0 = 14.6; II - 7.5+1.8+6.0+5.5+13.5 = 34.3; III - 6.7+2.0+6.4+4.0+11.2 = 30.3; IV - 4.0+1.0+3.0+3.7+9.5 = 21.2. Pedipalp strong ( Fig. 4F ), femur ventrally and dorsally with rather large black-tipped denticles, laterally with setae; patellae dorsally and laterally with smaller black-tipped denticles; tibiae with the same kind of denticles, but laterally a stripe with only bristles; tarsi ventrally with many microdenticles and bristles. Length of pedipalp segments: 1.1+0.5+0.7+1.5 = 3.8. Chelicera mediumsized ( Figs 4G–H ), basal segment with a group of black-tipped denticles dorsally, second segment dorsally with black-tipped denticles and bristles on the rest of the surface. Basal segment 1.7 long, second segment 1.6 long. Penis with wide base tapering slightly towards distal end ( Fig. 4I ); glans massive, with one pair of setae per side ( Figs 4J–L ), widened distally. Total penis length 2.3, glans length 0.3, stylus length 0.1. FIGURES 4A–L. Homolophus airyamani spec. nov. , holotype male. A Habitus, dorsal. B Eye tubercle, dorsal. C Femur I, dorsal. D Metatarsus I plus part of the second segment (= tarsomeres) of tarsus I, lateral. E, F Right pedipalp (E lateral, F mesal). G, H Right chelicera (G lateral, H mesal).

The type specimens were collected from a sparsely vegetated, rocky arid plain ( Fig. 5 ). Distribution . Known only from the type locality in Hormozgan Province, southern Iran.
