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…
The larva of Papuagrion is described and illustrated for the first time based on two specimens collected near Goroka, Papua New Guinea. The larvae were identified by matching the mitochondrial marker COI with that of an adult specimen collected at the same locality. The larvae were found in the leaf axils of Pandanus trees which…
Pseudagrion woodlarkensis sp. nov., a new damselfly species from Woodlark Island, Papua New Guinea, is described and male and female characters are illustrated. The new species differs from all regional congeners by having a predominantly yellow thorax with bold black stripes, and males can be clearly distinguished from all Papuan Pseudagrion species by the complex…
Lanthanusa bilineata, a new libellulid from the mountains of central New Guinea (holotype: Mekil Research Station (04°48′ S, 141°39′ E), leg. 1 September 2004, dep. at RMNH, Leiden), is described. The new species combines characteristics previously used to distinguish between Huonia and Lanthanusa with wing venation characteristic of the genus Huonia and accessory genitalia characteristic…
Papuagrion carcharodon, a new coenagrionid from the rainforest of Papua New Guinea’s Simbu Province, is described (holotype: 06°43′S, 145°05′E; 900 m a.s.l., 27 March 2004, to be deposited at Naturalis, Leiden). This new species is similar to P. ekari and P. pesechem but may be distinguished from both by the tooth-shaped lower branch of the…
