A new species of the genus Teinobasis Kirby is described from the Muller Range in Western Province, Papua New Guinea. Its male is distinguished from all other Teinobasis species by having a pale labrum, an extensively bright orange thorax, and ventrally bowed superior anal appendages that are markedly shorter than the plump, apically rounded inferiors. Characters of the male are illustrated, and the affinities of the new species are discussed.
We describe three new species of damselflies from streams draining into Lake Kutubu in Southern Highlands Province, Papua New Guinea. They are Drepanosticta johncanni sp. nov. (Platystictidae), Pseudagrion parafarinicolle sp. nov. (Coenagrionidae) and Wahnesia kutubuensis sp. nov. (Argiolestidae). Diagnostic characters of the males and, where available of the females, are illustrated and the probable affinities of the new species are discussed.
A new species of the synthemistid genus Palaeosynthemis is described from the Trauna River valley in Western Highlands Province, Papua New Guinea. The new species is most similar to P. cyrene from which it can be distinguished, among other characters, by the coloration of the pterostigma (jet-black in the new species vs brownish yellow in P. cyrene) and of the wing bases (not darkened vs strongly darkened). The new species also differs from P. cyrene in having a narrow, almost parallel-sided yellow lateral synthoracic stripe and a well-defined yellow marking along most of the ventral margin of the metepimeron. In P. cyrene the lateral synthoracic stripe is markedly wider and tapered, and the yellow element along the ventral margin of the metepimeron is absent. Characters of the adult male are illustrated and the affinities of the species are discussed.
Two new species of damselflies are described from central Halmahera in North Maluku Province, Indonesia. They are Drepanosticta pararudicula sp. nov. (Holotype MZB. ODON. 19257) and Nososticta halmahera sp. nov. (Holotype MZB. ODON. 19265). The two species are most similar to the Moluccan taxa D. rudicula and N. moluccensis respectively and their descriptions bring the total number of Drepanosticta species known from Halmahera to five and of Nososticta to two.
