Diagnosis

A species of Chiraziulus   , differing from C. kaiseri   by anterior gonopods not presenting a triangular shape in anterior view, by having equally sized anterior and posterior lobes of anterior gonopod telepodites, and by posterior gonopod having a spine-like process ending in a halberd-like structure.

Etymology

From Greek trōglo: cave, common prefix for terrestrial cave-dwelling animals, and Latin persicus: Iranian.

Type material

Holotype

IRAN: ♂, Kohgiluyeh and Boyerahmad Province , Khaeiz protected area, Mt. Khaeiz , 45 km southwest of Dehdasht city, Neyneh Cave, 30°40’18” N, 50°21’71” E, altitude 770 m (gonopods coated for SEM), 17 May 2012 ( ZMUC).

Paratypes

IRAN: same data as the holotype: 4 ♀♀ ( ZMUC); 1 ♀ and 3 ♂♂ (ZM CBSU).

Description

Males: 41–44 podous + 2 apodous rings, diameter 1.39–1.64 mm. Females: 39–51 podous + 2 apodous rings, and 53 + 0 podous rings, diameter 1.38–1.75 mm. Habitus typical of the genus, eyes absent. Six supralabral setae. Ozopore starting on 5 th body ring (except for one female paratype that presents teratological traits and in which ozopores start on 6 th body ring).

Male ( Fig. 9 View Fig )

Anterior gonopods ( Fig. 9 View Fig A–D) with remarkably long flagellum ( Fig. 9A View Fig , D–E), making a full loop from its insertion point on posterior face of anterior gonopod coxites pointing distad. Anterior gonopods with blade-shaped and apically rounded coxite (not of a triangular shape in anterior view as in C. kaiseri   ) ( Fig. 9 View Fig A–D); each coxite with 2 setae in mesal anterior view (s) ( Fig. 9B View Fig ) and a lateral ridge with 4 setae at mid-height (dp); external lateral margin slightly concave, with rugose-scaly microsculpture ( Fig. 9B View Fig ). Telepodite shorter than coxite, bi-lobed ( Figs. 9 View Fig A–D). Anterior and posterior lobes of telepodite (Ta and Tp) about the same size; anterior lobe with 8 setae, slightly concave on side facing posterior lobe; posterior lobe with 8 parallel setae. Flagellum (f) extremely long, covered with c. 5 µm long hair-like, retrorse processes and a pointed tip ( Fig. 9E View Fig ). Posterior gonopods ( Fig. 9 View Fig F–J) apically covered with setae and with a long slender spine-like process ending in a halberd-like expansion. Mesal sternal part of gonopods forming a trough covered with sharktooth-like denticles ( Fig. 9 View Fig I–J).

Habitat

The new species was discovered in the Neyneh Cave ( Fig. 10 View Fig ), located in the mountainous Khaeiz protected area, in Zagros Mountains, southwestern Iran. Neyneh Cave is situated in the warmer part of the province where the temperature at the surface reaches to 50°C during the summer. The temperature inside the cave is 25°C; the relative humidity is very high, 95–99.9%, and the CO 2 level is 613–700 ppm. There was no water flow in the cave. This cave is located in cliffs and has more than 700 m of horizontal maze development. It is located in an area with difficult access, thus protected from human pressure; however, there is some destruction due to the activities of treasure hunters. Chiraziulus troglopersicus   sp. nov. specimens were found in complete darkness, crawling on guano and cave walls. Some colonies of bats produce enough guano to cover the cave soil, providing an important source of organic matter for this subterranean trophic chain. Species richness in Neyneh Cave is relatively high and includes several arthropod taxa (Acari, Araneae, Oniscidea, Collembola, Orthoptera, Coleoptera   ), as well as some vertebrate taxa, such as gekkos, bats and hystricid rodents.
