. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. Taxonomy of the Myotis frater species group 19 Results Myotis frater in traditional conception is a complex species and should be divided into several distinct fomis, characterised by morphological and ecological charac- teristics and some peculiarities of their distribution. A detailed diagnosis is presented below for all the above-mentioned forms. Myotis frater Allen, 1923 Holotype. Adult male, No. 48039, American Museum of Natural History, from Yenping, Fukien Province, China. August 10, 1920. Collected by Diagnosis. Colour is not evident in the alcohol specimens, but is doubtless dark reddish brown (Allen 1923). Tail is long, about 50% of the total length; ears are short, barely reaching the muzzle when laid forward, tragus is longer than half of the pinna length. Membrane is attached to the base of the outer toe. Skull has short, upturned rostrum, elevated towards forehead (in profile) and slightly inflated brain case (Fig. 2). The upper canines are rounded on cingulum level, and bear two deep grooves on their lingual sides, and one strongly pronounced groove on back-labial sides of upper canines (Fig. 3). The third upper premolar (P3) is quite displaced inward from the tooth row. A metaloph is present on Ml and M2, but no protoco- nules. Fig. 2. Two types of the skull profile. Solid line: Myotis bucharensis and M. f. eniseensis ssp. nov.; dashed line: frater, longicaudatus, kagiiyae. The species includes 3 subspecies up to now: M / frater Allen, 1923; longi- caudatus Ognev, 1927; kaguyae Imaizumi, 1961. Ellerman & Morrison-Scott (1951) include M. f. longicaudatus into M. frater, based on similarity of measurements, which had been published earlier. Wallin (1969) considered it to be well correlated in all characters with M. f. frater and regarded them as synonyms. In 1956 Imaizumi described M.
