Material.

Holotype ♂ (SMF), IRAN, Māzandarān Province, Abbās Abād, Salmān Shahr, around Dāniāl Cave (36°39'N, 51°10'E), April 2014 (P. Beyhaghi).

Etymology.

The specific epithet is derived from the type locality; adjective.

Diagnosis.

So far, only two Raveniola species are known to occur in Northern Iran: Raveniola niedermeyeri and Raveniola vonwicki . The new species can be distinguished from Raveniola niedermeyeri by its twisted embolus (gradually bent in Raveniola niedermeyeri , Fig. 21). Raveniola mazandaranica sp. n. differs from the similar Raveniola vonwicki by the shape of its embolic tip and by having a tibial prolateral apical spine (arrowed on Fig. 15), lacking in sibling species. All three Iranian species differ in the number of their prolateral apical tibial spines: none in Raveniola vonwicki , two in Raveniola niedermeyeri , and one in Raveniola mazandaranica sp. n.

Leg I: 4.0 + 2.3 + 3.35 + 3.25 + 1.8. Leg II: 3.85 + 2.0 + 2.75 + 2.75 + 1.8. Leg III: 3.37 + 1.7 + 3.25 + 3.3 + 1.75. Leg IV: 4.2 + 2.0 + 3.35 + 4.75 + 2.0. Metatarsus I modified, with thinner proximal half and thicker distal half (Fig. 14). Spination of palp: femur 2d, 1pa; patella 0; tibia 2d, 1ra, 3p, 3vp, 2vr, 1vm; cymbium 4.

Paired claws: inner and outer margins with 7-11 teeth each. Spinnerets: PMS 0.3 long; PLS 1.2 long, apical segment triangle.

Palp as in Figs 15-17, femur slightly longer than tibia and about 1.5 thicker; patella longer than cymbium and wider than tibia; tibia prolaterally with one apical spine; bulb 2.7 shorter than tibia, embolus bent 3 times.

Distribution.
