MORPHOLOGICAL VARIATION AMONG EASTERN INDONESIAN ISLAND POPULATION OF HIPPOSIDEROS BICOLOR (CHIROPTERA HIPPOSIDERIDAE), WITH DESCRIPTIONS OF THREE NEW SUBSPECIES

WA Museum Records and Supplements | Updated 1 decade ago

Abstract: Hipposideros bicolor (Temminck, 1834) is recorded for the first time in the Indonesian Lesser Sunda islands of Sumbawa, Selaru, Sumba, Savu, Roti and Timor. Morphological comparisons of cranial, dentary, dental and external body characters and univariate and multivariate statistical analyses of measurements of these characters were carried out on 76 adult specimens from six islands in the Lesser Sundas and, for comparison, with specimens from Java and Peninsula Malaysia. This study reveals that H. bicolor differentiates morphologically into three subspecies, which are described herein. These subspecies, and an indeterminate subspecies from Sumbawa island, are closer phenetically to H. b. bicolor from Java than to H. b. atrox from Peninsula Malaysia.
