Abstract: In a collection of nidicolous gamasid mites collected in the winter of 1959 (7. xii.1959) from Anhui Province, a new species of Podocinum--Podocinum anhuense Wen,sp. nov. was found in a hamster's (Cricetulus barabensis) nest. Its specific charactersare given as follows: Body subrotund in shape, 388×325μ. Dorsal shield entire, its lateral marginswithout trace of incisions, but rolling down to the ventral surface around the border-line;its surface with minute tubercles forming a polygonal network, the polygonal areas beingsmooth. The shield bearing 19 pairs of setae, of which 9 pairs (the pair immediatelybehind the verticals and eight pairs on the posterior half) stout and ciliated on their distalhalf or two-thirds. Vertical setae situated considerably apart, and the distance betweenthe bases of two verticas approximately twice their individual length. Antero-lateralangles of the ventri-anal shield produced into wing-like "horns". Leg Ⅰ markedly elon-gated and modified into an antenna-like sensory organ, measuring 960μ in length.Tarsus Ⅰ (245μ) with 2 whip-like but unequal terminal setae (282 and 353μ respec-tively) and only one relatively short (35μ) but conspicuous subterminal seta. Tibia Ⅰmoderate in length (141μ). Leg Ⅱ measuring 607/μ, leg Ⅲ 550μ, and leg Ⅳ 650μ.The tectum consisting of three subequal prongs, the central one being slightly longer and4-forked distal1y, the lateral ones with 5--6 dentations externally at their proximal two-thirds. The gnathocoxa with 4 pairs of setae, the exterior gnathocoxal seta very shortand approximately one-third the length of the interior one. The gnathosomal grooveshallow and with 6 transversal rows of minute teeth.
