Our cordial thanks go to Carlos Drews for collecting T. perforatus on his field trip to Egypt in 1982. It was wonderful to learn that even 30 year old chromosomal suspensions can be used for FISH. Permission to conduct research in Malay sia was given by Economic Planning Unit UPE: 40/200/19/ 1466, The Sabah Parks Trustees (SP), Sarawak Forestry Depart ment (SFD), Sarawak Forestry Corporation (SFC) and Depart ment of Wildlife and National Parks (DWNP). We thank all of our collaborators especially Dr. Sivanathan, E. (DWNP) and Dr. Mar - klarin L. (SP). We thank Prof. Dato’ Dr. Mohd Tajuddin Ab - dullah who was previously from Universiti Malaysia Sarawak (UNIMAS) in providing all the assistance from the beginning of the expedition. Trip to Malaysia was supported by Mr. James Sowell, Department Biological Sciences and Natural Science Re search Laboratory, Texas Tech University, Ministry of Science, Technology and Environment of Malaysia and UNI-MAS. We also would like to thank all the members of 2006 and 2010 field expeditions especially Vicki J. Swier and Molly M. Macdonough in assisting in preparing the karyotypes. FAAK was supported by Ministry of Higher Educa tion Malaysia. CGSC has been supported by CNPq and CAPES (Brazil) during the development of this study.

N2 - We present a comparative molecular cytogenetic investigation of six emballonurid species using chromosome banding and cross-species chromosome painting with probes from Myotis myotis, supplemented by selected probes from human, tree shrew, and lemur. The main differences between the 2n = 42 Taphozous karyotype and the 2n = 44 chromosomal complement of Saccolaimus can be explained by one Robertsonian fusion, one type-b, and one type-c whole arm reciprocal translocation. The 2n = 24 karyotype of Emballonura is highly derived by splitting of 11 of the 25 chiropteran evolutionarily conserved units resulting in a total number of 36 segments. In contrast to the presence of several autapomorphies in the karyotypes of studied species from both subfamilies, no cytogenetic synapomorphy uniting Taphozoinae and Emballonurinae was found.
