A New Species of the Genus Anatemnus (Pseudoscorpiones, Atemnidae) from China

One new species belonging to Anatemnus Beier is reported from China under the name A. chaozhouensis sp. nov. 1. Introduction The pseudoscorpions genus Anatemnus belongs to subfamily Atemninae, family Atemnidae. It was erected by Beier in 1932 for the type species Chelifer javanus Thorell, 1883. This genus includes 18 known species which are widespread in Africa, Americas, and Asia. Most of them (11 species) distribute in Southeast Asia, and only one species, A. orites Thorell [1], was recorded from China [2, 3]. Anatemnus is characterized by the trichobothrial pattern of fixed chelal finger: the distance trichobothrium it from fingertip equals that of ist and isb, distance between est and esb is longer than that of ist and isb; pedipalpal patella expands not obviously and nearly oval [4]. Among the pseudoscorpions collected from Dong’an Town, Chaozhou City, Guangdong Province in the summer of 2011, we found one Anatemnus species new to science and described it here as A. chaozhouensis sp. nov. 2. Materials and Methods The material was preserved in 75% alcohol. The patterns of description and terminology follow [5, 6]. Terminology of genitalia follows [7]. All measurements are given in millimeters. Drawings were made with the aid of a prism mounted above the eyepiece of a compound microscope. Photographs were taken with a Leica M165 stereomicroscope. Detailed examination was carried out with a Nikon YS100 general optical microscope. Temporary slide mounts were made in glycerol. The following abbreviations are used in the text for trichobothria—b: basal; sb: sub-basal; st: sub-terminal; t: terminal; ib: interior basal; isb: interior sub-basal; ist: interior sub-terminal; it: interior terminal; eb: exterior basal; esb: exterior sub-basal; est: exterior sub-terminal; et: exterior terminal. The following abbreviations are used in the text for male genitalia—A: lateral apodeme; B: hooked branch; C: sclerotized bar; D: longitudinal fold of medial diverticulum; E: ejaculatory canal atrium; F: lateral rods; G: dorsal apodeme; H: ventral diverticulum; L: lateral lip of lateral apodeme. The specimens referred here are deposited in the Museum of Hebei University (MHBU), Baoding City, China. 3. Taxonomy 3.1. Anatemnus Chaozhouensis？？sp. nov. (Figures 1 and 2).
