Types.

Holotype ♂ (IZCAS): GREECE, Athens, Attica, Leondari Cave, 37°59'14.61"N, 23°49'47.03"E, elevation 553 m, 28 March 2013, S. Li leg. Paratypes 2♀ (IZCAS), same data as holotype.

Etymology.

The specific name is dedicated to Dr. Christos Arvanitidis of the Hellenic Centre for Marine Research in Crete, a leading taxonomist on Polychaeta; noun (name) in genitive case.

Diagnosis.

Leptonetela arvanitidisi sp. n. is similar to Leptonetela kanellisi but can be separated by the basal tibial spine with bifurcated tip (Fig. 1D) (not bifurcated in Leptonetela kanellisi ), the wave-shaped anterior margin of the atrium and the tightly twisted spermathecae (Fig. 2C); Leptonetela kanellisi has an arc-shaped anterior margin of the atrium and the spermathecae are loosely twisted (see Wang and Li 2011: figs 16-19).

Description.

Male (holotype). Total length 1.75 (Fig. 1A). Carapace 0.83 long, 0.72 wide. Opisthosoma 1.00 long, 0.65 wide. Prosoma yellowish, with one seta in the middle of the carapace. Ocular area with a pair of setae, eyes absent. Median groove, cervical grooves and radial furrows indistinct. Clypeus 0.10 high. Sternum and legs yellowish. Opisthosoma pale brown, ovoid, lacking distinctive pattern. Leg measurements: I 8.39 (2.25, 0.38, 2.45, 2.08, 1.23); II 7.14 (1.88, 0.38, 2.03, 1.72, 1.13); III 5.93 (1.73, 0.35, 1.62, 1.55, 0.68); IV 7.83 (2.13, 0.38, 2.15, 2.00, 1.17). Male palp (Fig. 1 C–D): tibia with 5 spines retrolaterally, the basal one strong, conspicuous, with bifurcated tip. Bulb with triangular embolus; prolateral lobe oval. Median apophysis (Fig. 1B) distal edge round, with six small teeth. Conductor membranous, triangular in ventral view.

Female (one of the paratypes). Similar to male in color and general features but larger and with shorter legs. Total length 2.03 (Fig. 2 A–B). Carapace 0.85 long, 0.73 wide. Opisthosoma 1.23 long, 0.90 wide. Clypeus 0.10 high.
