Etymology. This species is named in honor of Prof. Karim Kamali, the eminent Iranian Acarologist.

Type repository. Holotype female and two paratype females deposited at the Acarological collection, Department of Agricultural Entomology, Tarbiat Modares University (Tehran, Iran).

Diagnosis. N. kamalii sp. nov. can be distinguished by its long and serrate dorsal idiosomal setae, bifurcate ag3, ωI (4) six times shorter than tarsus length (25), ag1 (10) longer than ag4 (7), φ the same length as κ (2.5 Μm), palp tarsus (10–11) much shorter than stiletto (17.5–18). Diagnostic features of females are also provided in Table 1 .

Epimeral formula: 3-1-4-2. Tarsus apotele I absent ( Fig. 4 A). Tarsus I with three pairs of long setae (fastigials, tectals and prorals), small, club-like solenidion and pair of extremely small, vestigial unguinal setae on ventral side, closely associated with bases of prorals, u" bifurcate ( Fig. 4 B). Measurements: tarsus I length/width: 25/ 10, ft’ 16, ft”ζ 28, tc’ζ 15, tc”ζ 28, p’ζ 19, p”ζ 28, (u) 1.5, ωI 4. Solenidion ωI six times shorter than tarsus (sol ωI / half-length of tarsus I 0.32), tarsus I / ft" 0.92. Tibia I (19/12) with three long setae, solenidion and famulus approximate to each other. “Y”-shaped famulus κ (3) as long as clublike solenidion φ (3). Other legs (II–IV) each with two claws (ol) and ciliate empodium. Internal side of claws delicately roughened, no empodial hooks. Tarsus II ( Fig. 4 C) with minute, spherical, scarcely visible solenidion ωII (1 Μm).

Male: Not found.

Remarks. The caudal region of the new species is visible at the end of the opisthosoma in all three type specimens, but in other species of this genus it is usually ventral. This may be due to the amount of pressure applied to the body during slide-mounting. The small lobe at the end of the body in N. kamalii sp. nov. has not been reported in other species of this genus, but in the putatively closely related genus Lourus this has been reported as a differential character within this genus, being visible in L. testatus and L. citricolus . However, it seems that the presence of this character depends on the way the slide is made and can be seen in some other species in different genera of the family Tydeidae . The internal side of the claws seems rough to some extent in N. kamalii sp. nov. This character is difficult to see, but can be seen in some other collected materials of Neopronematus as well, but it never has been indicated in the descriptions of other Neopronematus species.

Differential diagnoses. Neopronematus kamalii sp. nov. is easily distinguished from N. aegeae by its nude idiosomal setae and simple ag3 (serrate idiosomal setae and bifurcate ag setae in N. kamalii ) and from N. rapidus by its shorter ex setae than ro and la, and long tarsal solenidion, being about half the length of tarsus I (ex setae longer than ro and la and ωI about six times shorter in N. kamalii ). The new species is more similar to N. lundqvisti , N. sepasgosariani , N. solani and N. neglectus in sharing several character states in common ( Table 1 ). Solenidion φ and famulus κ (3) are the same size in N. kamalii sp. nov. and N. neglectus , but the dorsal idiosomal setae are shorter in N. neglectus . The new species is distinguished from N. solani by the longer ωI (8), longer tectal setae and κ slightly shorter than φ in N. solani . Neopronematus sepasgosariani differs from the new species by having seta d1 more or less equal to the distance d1-e1 and a slightly longer palp tarsus (17) than stiletto (15). Neopronematus lundqvisti has a much longer ωI (13) that is approximately as long as half the length of tarsus I, but N. kamalii sp. nov. has a shorter ωI (4) that is about six times shorter than the tarsus length (25). Further diagnostic character states are listed in the diagnosis, key, and Table 1 .
