Bacula of the examined forms, based on Strelkov 1989 (M bucharensis, M. frater longicaudatus, M. f. eniseensis ssp. nov.), Yoshiyuki 1989 (M frater kaguyae), and the authors' new data (M frater frater, the type specimen). In the subspecies of M. frater (excluding M. f. eniseensis) and in M bucharensis, the interfemoral membrane has single hairs on the inside, and these hairs form small bunches only at the tail base.
. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. 1 mm longicaudatus. Fig. 5. Bacula of the examined forms, based on Strelkov 1989 (M bucharensis, M. frater longicaudatus, M. f. eniseensis ssp. nov.), Yoshiyuki 1989 (M frater kaguyae), and the authors' new data (M frater frater, the type specimen). In the subspecies of M. frater (excluding M. f. eniseensis) and in M bucharensis, the interfemoral membrane has single hairs on the inside, and these hairs form small bunches only at the tail base. In M. f. eniseensis, the inside of the membrane carries bunches of hairs on two thirds of the tail length from its base. Skull. The two types of skull profiles are characteristic of these bat species (Fig. 2). The first one is characterised by strongly abrupt nose-frontal crook and shorter rostral part (M / frater, M. f. longicaudatus, M. f. kaguyae); in the other type the rostrum is relatively long and rises smoothly (M bucharensis and M / eniseensis) enough. The skull shapes for all the forms were compared through stepwise discriminant functional analysis. First all the 19 cranial measurements were taken into account, and only 10 of them (the most significant ones) had been taken into the final analysis. The stepwise discriminant function analysis has revealed a high level of discrimination between the subspecies and 100% correct definition of all specimens (Fig. 4). Teeth. No grooves can be found on back-labial sides of upper canines in M. f. eniseensis, but there is one in M. f. frater (deep in M / kaguyae and small in M / longicaudatus) and two well expressed grooves in M bucharensis. All forms differ in general shape of the upper canines (see diagnosis and Fig. 3)..
