Diagnosis. Cx-IV extending posterior to genital field; excretory pore posterior to line of primary sclerotization, Vgl-2 a little posterior to excretory pore; gnathosoma with a long rostrum, ventral margin curved; P-2 longer than P-4 (ratio P-2/P-4 1.18-1.22), ventral projection of P-2 strongly pronounced, but not curved distally, distal margins of P-2 and P-3 without denticles, ventral protuberance of P-4 forming an unique tip bearing one long, and three short hairs; postgenital area large. Males: Median suture line of Cx-II+III short; genital field roundish.

Etymology. Named for its occurrence in Hormozgan Province.

Remarks. Torrenticola hormozganensis sp. nov. is rather similar to T. arabica Smit & Pešić, 2010 from northern Oman ( Smit & Pešić 2010), in respect to the general morphology of the idiosoma (relatively short median suture line of Cx-II+III and roundish genital field in males, Cx-IV posteriorly extending well beyond genital field in both sexes) and the gnathosoma with a long rostrum. The main difference is found in the ventral projection on P- 2 which distinctly curves distally in T. arabica (see Smit & Pešić 2010). Further differences are the excretory pore and Vgl-2 shifted from the line of primary sclerotization in both sexes of T. hormozganensis .

Habitat. Sandy/bouldery streams, with strong exposure to sunlight and without vegetation ( Fig. 44C).

Distribution. Iran; Hormozgan Province.
