A new species of Hoya R.Br. from Sulawesi (Indonesia), Hoya isabelchanae Rodda & Simonsson, is described and illustrated. It is one of the largest flowered species in Hoya section Acanthostemma (Blume) Kloppenb. Its flowers are of comparable size to those of Hoya benchaii Gavrus et al., Hoya kloppenburgii T.Green, Hoya rundumensis (T.Green) Rodda & Simonsson and Hoya sigillatis T.Green ssp. sig...

A hundred years ago, the Toraja people did not exist. "Toraja" was merely a derogatory term applied by the Bugis and Makassarese living in the lowlands of the southwest peninsula of Sulawesi (then called Celebes) to any of the many different peoples living in the mountainous regions of the peninsula and central Sulawesi. Today, Tana Toraja (Toraja Land) is an administrative district in the prov...

Megascogaster wallacei sp. n. is described from Sulawesi, Indonesia. This is the first representative south of the Philippines and is only the second species of this rare genus described since the type species, M. elongata Baker, 1926. The presence of Megascogaster in Sulawesi, a part of Wallacea, points to a broader distribution of the genus in Southeast Asia. A redescription of M. elongata an...

For the past century, the genus Styloctenium Matschie has been known to contain a single species restricted to Sulawesi and the nearby Togian Islands. Styloctenium has a unique pelage, characterized by white supraocular spots and a white rostral stripe on an otherwise mostly orange pelage. Several additional features characterize the genus, including the loss of i1 and m3, rudimentary state of ...

The present report describes Syphacia (Syphacia) maxomyos sp. n. (Nematoda: Oxyuridae) from two species of spiny rats, Maxomys musschenbroekii from Sulawesi and M. whiteheadi from Sumatra. It is characterized by a cephalic plate extending laterally with dorsoventral constriction and stumpy eggs with an operculum rim reaching pole. It is readily distinguishable by the former feature from all of ...

Worldwide coral reef decline appears to be accompanied by an increase in the spread of hard coral diseases. However, whether this is the result of increased direct and indirect human disturbances and/or an increase in natural stresses remains poorly understood. The provision of baseline surveys for monitoring coral health status lays the foundations to assess the effects of any such anthropogen...

We collected data on the distribution of booted macaques (Macaca ochreata) in Faruhumpenai Nature Reserve in South Sulawesi, Indonesia, in order to assess its conservation status. Methodology included censuses conducted along piecewise linear transects established at two sites from April – July 2006. The total distance walked was 45 km for the Matano site, and 20 km for the Kasintuwu site. Grou...

This account of the riverine ichthyofaunas from the islands of Buton and Kabaena, off south-eastern mainland Sulawesi, represents the first detailed quantitative checklist and ecological study of the riverine fish faunas in the biological hotspot of Wallacea. The results are based on analysis of samples collected by electrofishing at a wide range of sites from July to September in both 2001 and...

Abstract. Litaay M, Piri R, Jabir NB, Priosambodo D, Putra AW. 2023. Diversity of marine tunicate from waters Pannikiang Island and Badi South Sulawesi, Indonesia. Biodiversitas 24: 1431-1437. The number tunicates is currently known for approximately 3000 species, but it estimated that there are still 1000-2000 more species have not been described globally. Spermonde Archipelago in Sulawesi a h...

Although studies of ancient lake fauna have provided important insights about speciation patterns and processes of organisms in heterogeneous benthic environments, evolutionary forces responsible for speciation in the relatively homogenous planktonic environment remain largely unexplored. In this study, we investigate possible mechanisms of speciation in zooplankton using the freshwater diaptom...
