| A recent collection of bats from northern Sulawesi (Celebes), Halmahera and Bacan (Batjan), Indonesia, contains representatives of three macroglossine genera. A specimen of Eonycteris rosenbergii (Jentink, 1889) from northern Sulawesi — a species previously known only from the immature type specimen — together with an additional, previously unreported specimen confirms the diagnostic value of the absence of the third lower molar. The validity of this taxon has been questioned by several authors, who suggested that E. rosenbergii is based on an anomalous specimen of E. spelaea (Dobson, 1871). Other material of Eonycteris from Sulawesi, referable to spelaea, is discussed, with the first record for the island of Muna (Moena), and comparative notes are given... |

| The bush-warbler Bradypterus mandelli (Brooks, 1875) was described from Sikkim, and numerous specimens from India were identified with it, but it was synonymised with the brown bush-warbler Bradypterus luteoventris (Hodgson, 1845) in 1881. In 1952, east Asian populations were grouped under the name of the Luzon form of the russet bush-warbler, Bradypterus seebohmi (Ogilvie-Grant, 1895). This taxonomy, however, failed to associate the Indian form and its available name mandelli, which received limited usage until 1919, with seebohmi, a matter reviewed and corrected herein. Specimens prove that mandelli has long been known from India, Bhutan, and Myanmar (Burma). The Thai population, previously placed in idoneus (Riley, 1940), belongs instead with the... |

| The Large-tailed Nightjar Caprimulgus macrurus Horsfield, 1821, complex, as currently recognized, comprises 12 taxa which are grouped into four species based on their territorial songs. However, species limits are based on very small samples of a limited number of taxa in the complex. To further document species limits in the complex, we analysed 109 sound recordings representing all recognized taxa. Principal components analysis suggests the existence of six vocally distinct groups within the complex. Discriminant function analysis assigned 98-100% of individuals correctly to their group. Each of these groups differs diagnosably from all other groups by up to eight vocal characters, and each group is recognizable by ear. We propose to treat these six... |
