CSORBA Department of Zoology, Hungarian Natural History Museum H-1083 Ludovika tér 2, Hungary. E-mail: csorba@zoo.zoo.nhmus.hu Abstract - Detailed morphological investigation of the type specimens of Rhinolophus pusillus, R. lepidus shortridgei, R. borneensis, R. affinis, R. thomasi septentrionalis and R. philippinensis montanus have resulted in designation of lectotype specimens, taxonomical revisions and better understanding of specific characters. With 19 figures. Key words - Rhinolophus, taxonomy, lectotype designation. INTRODUCTION Investigation of the type specimens is essential for taxonomical and systematic studies, which - by definitions of specific-subspecific limits - provide the identification basis for other disciplines as ecology, physiology or biogeography. This is especially true in the case of groups with several hardly separable species such as the family of horseshoe bats, Rhinolophidae. According to our knowledge, the family comprises 71 recent species all belonging to the single genus Rhinolophus. Several of them are known by few specimens only and their original descriptions are frequently not detailed enough for sure indentification. For these reasons, in the last four years I visited several collections in order to study the available type specimens of the majority of the species, and made drawings, detailed descriptions and took measurements. Furthermore, the study has resulted in some lectotype designations and taxonomical revisions which are (in the case of southeast Asian species) presented here. Abbreviations of measurements are: FA - forearm length; SL - greatest length of skull from front of canine to occiput; CM

3 - crown length of maxillary toothrow. All measurements are given in mm; forearm lengths were taken from dry and alcohol-preserved specimens to the nearest 0.1 mm, craniodental measurements were collected by digimatic caliper of 0.01 mm accuracy. Museum acronyms used in this paper are as follows: AMNH - American Museum of Natural History, New York; BM(NH) - The Natural History Museum, London, formerly British Museum (Natural History); FMNH - Field Museum of Natural History, Chicago; HNHM - Hungarian Natural
