Material.

Holotype ♂ (SMF) - IRAN: Khorāsān-e Jonoubi Province, Qāen County, Kārizan (33°53'N, 59°49'E), May 1, 2012 (O. Mirshamsi).

Etymology.

Named after our colleague and friend Seppo Koponen (Turku, Finland), a famous Finnish arachnologist on occasion of his 70th birthday; noun.

Diagnosis.

The new species has a rather short embolus like in Anemesia birulai (Spassky, 1937) (cf. Spassky 1937, fig. 2). Other congeners occurring in Central Asia have distinctly longer emboli, for example Anemesia karatauvi (Andreeva, 1968) and Anemesia incana Zonstein, 2001 (Figs 9-10). Anemesia koponeni sp. n. differs from the former species by larger body size (15 vs. 10 mm), much darker general coloration (chestnut-brown vs. light yellowish-brown), as well as by longer and spinose palpal tibia (shorter and aspinose in Anemesia birulai ). Finally it differs, from the similar Anemesia tubifex (Pocock, 1889) by its narrower eye field with the AME closer to each other (cf. Pocock 1889, fig. 2d).

Description.

Total length 15.2 including chelicerae. Color in alcohol: carapace, palps and most part of legs reddish-brown; eye tubercle brownish-black; clypeus, chelicerae, femora I–II dorsally dark reddish-brown; sternum, labium, maxillae, palps and legs ventrally yellowish-brown; abdomen dorsally with an indistinct pattern consisting of a short median stripe and a few pairs of interrupted transverse fasciae; metatarsi III-IV, tarsi I-IV, ventral abdominal surface and spinnerets light yellowish-brown. Carapace 6.0 long, 5.2 wide. Eye sizes and interspaces: AME 0.17, ALE 0.25, PLE 0.20, PME 0.12, AME–AME 0.20. Cheliceral rastellum weak. Maxillae with about 15 small cuspules each. Sternum 3.15 long, 2.50 wide.

Spination. Palp: femur 3d, 2pd; patella 1p; tibia 2v; tarsus 10d. Leg I: femur 4d, 3pd, 3rd; patella 2p; tibia 3p, 3r, 6-8v; metatarsus 1d, 1p, 1r, 5v. Leg II: femur 4d, 3pd, 3rd; patella 2p; tibia 3p, 2r, 9v; metatarsus 2d, 3p, 1r, 7v. Leg III: femur 3d, 3pd, 3rd; patella 2p, 1r; tibia 1d, 3p, 3r, 6v; metatarsus 3p, 4r, 7v; tarsus 2v. Leg IV: femur 3d, 3pd, 3rd; tibia 1d, 1p, 3r, 6v; metatarsus 1d, 2p, 5r, 7v; tarsus 2v. Patella IV and tarsi I–II aspinose.

Scopula: distal on metatarsi I–II, present on tarsi I-III, absent on tarsus IV. Paired claws: inner and outer margins with 6-7 teeth each. Spinnerets: PMS 0.53 long; PLS 2.25 long; apical segment triangle.

Palp as in Figs 5-8, thin, femur slightly longer than tibia, and as long as patella; bulb as long as patella, bulb (with embolus) 2.3 longer than widest diameter of bulb; embolus without distinct base, its length subequal to length of bulb.

Distribution.

The species is known only from the type locality. It is the southwesternmost record of the genus.
