Three new species of the genus Zodarion Walckenaer, 1826, from China, are described as Zodarion apertum sp. n. (♂♀, from Xinjiang), Z. planum sp. n. (♂, from Shaanxi), and Z. ovatum sp. n. (♂♀, from Yunnan).
Asia, italicum group, lutipes group, taxonomy, zodariides
The genus Zodarion was established by Walckenaer in 1826, with Enyo nitida Audouin, 1826 as its type species.
Presently, Zodarion is the largest genus of the subfamily Zodariinae, and includes 160 species. The genus has been recorded in European, Asian, and North African countries (
All specimens have been preserved in 75% ethanol and were examined, illustrated, and measured under a Tech XTL-II stereomicroscope equipped with an Abbe drawing tube. Photographs were taken with a Leica M205A stereomicroscope fitted with a Leica DFC550 camera and LAS software (ver. 4.6). Carapace length was measured medially from the anterior margin to the rear margin of the carapace. Eye size was measured as the maximum diameter of the lens in dorsal or frontal view. The measurements of legs are shown as total length (femur, patella, tibia, metatarsus, tarsus). Only one paratype was measured. Epigynes were cleared in a warm solution of potassium hydroxide, and then transferred to 75% ethanol for drawing. All measurements are given in millimeters. All specimens studied are deposited in the Museum of Hebei University (

Most Zodarion species are active at night and hide during the day in self-made retreats.
Holotype ♂ (Z-Xinjiang-200905-11), Luntai County (41°22'N, 84°11'E), Xinjiang Uygur Autonomous Region, China, 27 May 2009, Dong Sun leg. Paratype: 1 ♀ (Z-Xinjiang-200905-12), same data as holotype.
The male of Z. apertum sp. n. is very similar to that of Z. mongolicum (Marusik & Koponen, 2001) in having a fold on the apical tegular apophysis, a relatively wider bulb, and the wide and flat apical part of the retrolateral tibial apophysis enlarged. However, it can be distinguished from Z. mongolicum by the posteriorly downward direction of the embolic base (down-retrolaterally in Z. mongolicum), the retrolateral tibial apophysis with aclinal apical margin in ventral view (flat in Z. mongolicum), and the posterior tip of the conductor being at the 6-o’clock-position (5-o’clock-position in Z. mongolicum) (Figs
The specific name is from the Latin apertum, in reference to the uncovered terminal of the retrolateral tibial apophysis; adjective.

Holotype ♂ (Z-Shaanxi-198606-22), Baoji City (34°22'N, 107°09'E), Shaanxi Province, China, 22 June 1986, Mingsheng Zhu leg.
The male of Z. planum is very similar to those of Z. sytchevskajae Nenilin & Fet, 1985, Z. chaoyangense Zhu & Zhu, 1983, and Z. furcum Zhu, 1988, as all have dorsolateral processes extending from the middle part of the retrolateral tibial apophysis, though Z. planum can be distinguished from the others by the wide and fluent margins of the dorsolateral process (obviously curving in the other three species) (Figs
The specific name is from the Latin planum, in reference to the dorsolateral hook-shaped process of the retrolateral tibial apophysis; adjective.

The two new species Z. apertum sp. n. and Z. planum sp. n., together with most known East Asian and Central Asian species of the Zodarion (i.e. Z. asiaticum Tyschchenko, 1970, Z. bekuzini Nenilin, 1985, Z. chaoyangense Zhu & Zhu, 1983, Z. continentale Andreeva & Tyschchenko, 1968, Z. furcum Zhu, 1988, Z. mongolicum (Marusik & Koponen, 2001), Z. nenilini Eskov, 1995 (also distributed in European area and Urals of Russia), Z. proszynskii Nenilin & Fet, 1985, Z. schmidti (Marusik & Koponen, 2001), Z. spasskyi Charitonov, 1946, Z. hunanense Yin, 2012, Z. sytchevskajae Nenilin & Fet, 1985, Z. volgouralensis (Ponomarev, 2007) (also distributed in Astrakhan of Russia), and Z. zebra Charitonov, 1946) appear to comprise an undescribed group with the following common characters: the long and thin embolus rising at the prolateral or basal part of the tegulum; tegular apophysis wide and strong, with a downwardly-directed hook; a modified apical portion of the retrolateral tibial apophysis turning dorsally; cymbium with tutaculum; epigyne with incised posteromedian margin and median hood; apical parts of spiraled spermathecae converging. They are different from the lutipes group (
Zodarion hunanense was described based only on a female specimen from Hunan province of China. The possibility exists that Z. planum sp. n. is conspecific with Z. hunanense.
Holotype ♂ (Z-Yunnan-200505-18), Yuanmou County (25°51'N, 101°45'E), Yunnan Province, China, 26 May 2005, collector unknown. Paratypes: 71 ♂ (Z-Yunnan-200505-19 - Z- Yunnan-200505-89) and 33 ♀ (Z- Yunnan-200505-90 - Yunnan-200505-122), same data as holotype.
The males of Z. ovatum sp. n. are similar to those of Zodarion nitidum (Audouin, 1826), Z. christae Bosmans, 2009, Z. deltshevi Bosmans, 2009, and Z. samos Bosmans, 2009 because of the flagelliform embolus rising at the basal part of the tegulum, the small tegular apophysis and the retrolateral tibial apophysis terminally pointed in ventral view, though it can be distinguished from the others by the small oval base of the embolus (triangular in the other three species), and the lack of a gland in the base of the cymbium (present in the other three species). The females of Z. ovatum sp. n. are similar to female Z. soror (Simon, 1873) in having swollen copulatory ducts, and also to Z. ludibundum Simon, 1914 and Z. nigriceps (Simon, 1873) by the oblique lateral margines of epigyne, but the copulatory ducts of Z. ovatum sp. n. are longitudinally arranged (Figs
The specific name is from the Latin ovatum, in reference to the oval shape of the swollen copulatory ducts; adjective.

The males of species Z. ovatum sp. n. belong to the lutipes group with their long embolus rising at the posterior part of the tegulum; tibial apophysis short, robust and without lateral process. The females of Z. ovatum sp. n. resemble the species of the italicum group (
