Ordo: Araneae
Familia: Zodariidae
Genus: Acanthinozodium
Name
Acanthinozodium ovtchinnikovi Zamani & Marusik, 2021 sp. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype ♂ palp (ZMMU), Turkmenistan: Mary Region: Kushka Dist., ca 18 km S of Kyzyldzhar Kordon, ca 1 km ESE of Eroilandaz, 35°39'N, 61°50'E, 7.04.2002 (A.V. Gromov).
Etymology
The new species is named after our late colleague Sergei V. Ovtchinnikov who made important contributions to the study of Central Asian spiders.
Diagnosis
The new species differs from the congeners in the region (except A. parmida sp. nov.) by the small size of the palp (cymbium 0.28 long, vs. > 0.6) and the unique embolus which has a long furrow with a serrate ventral margin (Fig. 22E). It is closely related to A. parmida sp. nov. from central Iran, from which it can be differentiated by having a longer than wide bulb (vs. almost as long as wide), relatively longer cymbium (length/width ratio 1.86 vs. 1.4), and a different shape of median apophysis (anterior portion larger than posterior one, vs. opposite; cf. Figs 22G and 19B).
Description
Male. Body missing. It is assumed to be a very small zodariid based on the size of the palp.
Palp as in Fig. 22D, E, G–I. Ventral tibial apophysis lacking; RTA almost triangular, slightly longer than tibia; cymbium longer than wide; sperm duct tracking margin of tegulum, lacking any turns; median apophysis longer than wide, with anterior part larger than posterior part; embolus originates at about 8:00 o'clock position with its terminal 2/3 having a longitudinal furrow (Er) with a finely serrated ventral margin.
Female. Unknown.
Note
The sample collected by Gromov contained three males. The palp of one specimen was dissected and imaged with a SEM in 2005. Then, all three specimens were given to Ovtchinnikov who was planning to revise this group. After his death, his collection was transferred to Almaty, Kazakhstan by Alexander Gromov and is now inaccessible.
Distribution
Known only from the type locality in Mary Region, southeastern Turkmenistan (Fig. 32).
