Revision of the Asian pseudoscorpion genus Tullgrenius Chamberlin, 1933 (Pseudoscorpiones: Atemnidae: Miratemninae), a tale of intraspecific variation
The Asian pseudoscorpion genus Tullgrenius Chamberlin, 1933 is revised. A neotype is designated for Tullgrenius indicus Chamberlin, 1933, based on topotype material and a detailed description of its male is provided. Two new synonymies are proposed: Tullgrenius vachoni Murthy, 1962 syn. nov. and Tullgrenius orientalis Sivaraman, 1980 syn. nov. = T. indicus. Two distinct colour morphs of T. indicus are recognized: a brown and black morph. Supplementary descriptions and illustrations for Tullgrenius afghanicus Beier, 1959 and Tullgrenius compactus Beier, 1951 are detailed with current distribution of all the known Tullgrenius spp..
