First report the genus Dendrochernes Beier, 1932 (Pseudoscorpiones: Chernetidae) from China, with description of a new species
It borders with the country of Kazakhstan, Mongolia and Russia.While examining pseudoscorpion specimens collected from Xinjiang, two chernetid specimens presenting the generic characters of Dendrochernes were examined: eye spots lacking or indistinct; tergites divided except the last one and finely to moderately granulate; setae of body and palps broadened and thickened, denticulate and short, never strongly clavate; rallum with 4 (but occasionally 3) blades; palps stout, finely to moderately granulate; accessory teeth of chelal fingers numerous; tactile seta st of movable finger nearer to sb than to t; fixed finger with tactile seta ist at the level of or very little distal to the level of est; tarsus IV with a tactile seta located distal to the midpoint of the tarsus, being 0.6 to 0.7 of the length of the tarsus from the proximal margin of the segment; the spermatheca of the female with two long, slender tubules, of uniform diameter throughout, greatly coiled, and without a terminal enlargement or bulb [Chamberlin, 1934;Hoff, 1956].This is the first record of this genus in China, and we describe and illustrate the new species under the name Dendrochernes mahnerti sp.n. Material and MethodsThe specimens referred to here are preserved and examined in 75% alcohol and deposited in the Museum of Hebei University (MHBU), Baoding City, China.Photographs were obtained using a Leica M205a stereomicroscope equipped with a Leica DFC425 Camera and LAS software (Ver.4.0), which was also used for drawings (with a drawing tube) and measurements.Detailed examination was carried out with an Olympus BX53 general optical microscope.Temporary
