The distribution of the poorly known Central Asian wolf-spider Oculicosa supermirabilis Zyuzin, 1993 is clarified, discussed and mapped on the basis of both original and literature-derived data. The species is currently known from the Turan Lowland between the 41st and 43rd degrees of latitude north; its distribution coincides with that of the grey-brown desert soil and lies within the geobotanical sub-zone of southern deserts. Both sexes are also illustrated and diagnosed

Logunov & Alexander V. Gromovdoi: 10.5431/aramit4208Abstract: The distribution of the poorly known Central Asian wolf-spider Oculicosa supermirabilis Zyuzin, 1993 is clarified, discussed and mapped on the basis of both original and literature-derived data. The species is currently known from the Turan Lowland between the 41st and 43rd degrees of latitude north; its distribution coincides with that of the grey-brown desert soil and lies within the geobotanical sub-zone of southern deserts. Both sexes are also illustrated and diagnosed.Key words: burrowing wolf-spiders, Central Asia, distributional pattern, new records Oculicosa supermirabilis is the type species of the monotypic genus Oculicosa Zyuzin, 1993. Both the genus and type species were described in detail by ZYUZIN (1993), who also discussed the detailed palpal morphology of a number of lycosids and the provi-sional tribal classification of the Lycosinae. The genus Oculicosa can be easily distinguished from all other Central Asian genera of burrowing Lycosidae by the following characters: the distinctly elevated cephalic region, the presence of two retromarginal teeth, the absence of tarsal scopulae, and leg II the shortest (see LOGUNOV 2010, for further details). The latter author also provided two additional records for O. supermi-rabilis from the SE part of Kazakhstan. Nevertheless, the distribution of this species in Central Asia and its biology remains virtually unknown. Recently, a large unsorted collection of Central Asian Lycosidae became available to the first author (courtesy of Alexei Zyuzin; Almaty, Kazakhstan). This collection contains an extensive series of O. supermirabilis collected from a few localities of Central Asia, allowing us to clarify the species’ distribution. Thus, the aim of this short note is to consolidate all known records of O. supermirabilis from Central Asia available to date and to outline its range within the studied area.MethodsIn order to clarify both published (ZYUZIN 1993, LOGUNOV 2010) and unpublished records of O. supermirabilis we drew upon the field notebook of A. A. Zyuzin – who collected the majority of the studied material – topographic maps 1:100000, soil maps, maps of the modern administrative subdivision of Ka-zakhstan, Uzbekistan and Turkmenistan, and satellite images available at the website maps.google.com. The map presented hereinafter has been prepared using the computer programmes GPSMapEdit 1.0.57.3, ESRI ArcGIS 9.3 and Blue Marble Geographic Calculator 6.3. For each geographic name given under ‘Material examined’ we have provided several variants which are available on various maps; of which the first given name is the one currently used. The (re)examined material is deposited in the Siberian Zoological Museum, Novosibirsk, Rus-sia (SZMN; curator: Dr G.N. Azarkina) and the Manchester Museum, University of Manchester, UK (MMUM; curator: D.V. Logunov).Oculicosa supermirabilis Zyuzin, 1993 (Figs. 1-6)Material examinedKazakhstan: 1612 (SZMN, 001.4352), South Kazakh-stan [=Chimkent, Shymkent] Area, Arys’ Distr., Kyzylkum Desert, S foothills of Karaktau [=Kairaktau] Hills, c. 41.1 km W of Bairkum, nr.

A. Zyuzin leg.DiagnosisO. supermirabilis is easily distinguished from all the burrowing wolf-spiders of Central Asia by the wide and plate-shaped median apophysis with a transverse ridge (Figs 1-2) in males and by the narrow, long epigynal atrium (Fig. 4) and the very short, ovoid spermathecae in females (Fig. 5). Both sexes can also be easily distinguished by the pronounced slope of the thoracic region of the carapace and the unusually large PMEs and PLEs, compared to the eyes of the first row (see LOGUNOV 2010: figs 4-5). It is worth mentioning that the conformation of the synembolus and the embolus of O. supermirabilis is almost identical to that of Lycosa tarantula (Linnaeus, 1758), the type species of the genus Lycosa Latreille, 1804: in both species these structures are of the same shape and size (cf. Fig. 3 and fig. 1 in LOGUNOV 2010). Yet, both genera are clearly distinct (see LOGUNOV 2010, for further details).While diagnosing O. supermirabilis, ZYUZIN (1993) mentioned Lycosa alticeps (Kroneberg, 1875) from Central Asia and L. medica (Pocock, 1889) from Iran as closely related species. However, he did not mention whether they should be included in Oculi-cosa or not. Although both species were placed in the genus Hogna Simon, 1885 by ROEWER (1955), their actual taxonomic assignment and status are in need of urgent revision. This problem is outside the scope of the current study and will be dealt with by one of us (DL) in the future.DescriptionSee ZYUZIN (1993) for a detailed description both of the genus Oculicosa and of the type species O. supermirabilis.Distribution To date, the species has been recorded from Kazakh-stan (ZYUZIN 1993, LOGUNOV 2010; present data), Uzbekistan (present data) and Turkmenistan (present data). All the records came from the Turan Lowland between the 41st and 43rd degrees of latitude north: Ustyurt Plateau and Kyzylkum Desert (Karaktau Hills and their vicinities) (see Fig. 6).Notes on ecologyAdult specimens are active in April–May; females make permanent vertical silk-lined burrows with Fig. 6: Collection localities of Oculicosa supermirabilis Zyuzin, 1993. Closed dots – original data), open dots – literature-derived data.Notes on Oculicosa supermirabilis 51self-closing trapdoors (A. Zyuzin pers. comm.). The species prefers gypsiferous, vegetation-less plots on grey-brown desert soil of pelitophytic mechanical composition (= ‘white clay’ sensu A. Zyuzin pers. comm.), and occurs at elevations between 47 and 376 m a.s.l. This soil type is only common on several plateaus and along erratic mountains and hills of the Turan Lowland (see MINASHINA et al. 1968, ZHIKHAREVA et al. 1969, FAIZOV 1970). The cur-rently known distribution of O. supermirabilis coin-cides well with the distribution of this soil type, and lies within the geobotanical sub-zone of southern (warm-temperate) deserts (AKZHYGITOVA et al. 2003). The area of this species’ distribution is charac-terized by an annual solar radiation of 140-150 kcal/sm2 and by very low values of annual precipitation of 75-100 mm (KUVSHINOVA 1968).AcknowledgementsWe are most grateful to the following colleagues: Dr Galina N.

The cur-rently known distribution of O. supermirabilis coin-cides well with the distribution of this soil type, and lies within the geobotanical sub-zone of southern (warm-temperate) deserts (AKZHYGITOVA et al. 2003). The area of this species’ distribution is charac-terized by an annual solar radiation of 140-150 kcal/sm2 and by very low values of annual precipitation of 75-100 mm (KUVSHINOVA 1968).AcknowledgementsWe are most grateful to the following colleagues: Dr Galina N.
