The Sulawesi species of the genera Libellago and Sclerocypha are revised. L. asclepiades, L. rufescens, L. xanthocyana and S. bisignata are redescribed, and three species of Libellago- one with four subspecies – are described as new to science, viz. the closely allied L. daviesi sp. nov. from the northern arm of Sulawesi and L. man-ganitu…
Neurobasis awamena, a new calopterygid species from the southern highlands of New Guinea (holotype: Pimaga area, 6°30′S, 143°30′E, 27 vii 1994, deposited at Naturalis, Leiden) is described and figured. It is distinguished from the widespread N. australis by its longer legs, irregular teeth on the male cerci, and the sharp demarcation of the iridescent color…
Information on the origin of distribution patterns shown by freshwater invertebrates in the Indo-Australian Archipelago is poor. Here we present a molecular based hypothesis of the phylogenetic relationships of Argiolestidae, a family of damselflies found throughout the tropical parts of the Eastern Hemisphere. We use this to address the following questions: (1) did Argiolestidae colonize…
In this article the genus Argiolestes s.str. is defined and three new species belonging to this group are described: A. foja sp. nov. (holotype: Foja Mountains, Indonesia, dep. in MBB}); A. muller sp. nov. (holotype: Baia River, Papua New Guinea, dep. in SAMA); A. roon sp. nov. (holotype: Roon Island, Indonesia, dep. in BPBM). New…
The reproductive behaviour of Neurobasis kaupi was studied for the first time in Central and South Sulawesi. The species was recorded in a wide variety of clear and fast flowing creeks, streams and rivers, mostly in forested areas. The males were territorial and defended potential oviposition sites, a limited resource. Territory owners demonstrated their presence…
