Nososticta rufipes sp. nov. is described from Misool Island (Indonesia, Papua Barat, Kabupaten Raja Ampat). New records and notes on the species of the genus Nososticta on the Bird's Head Peninsula and Raja Ampat Islands are presented. Nososticta lorentzi (Lieftinck, 1938) is placed in synonymy with N. nigripes (Ris, 1913). © 2014, © 2014 Worldwide Dragonfly Association. Source

Aim: To explore the phylogenetics and historical biogeography of the dragonfly family Petaluridae (known as 'petaltails'), a relict dragonfly group with unique habitat and life history attributes. Location: Australia, New Zealand, Japan, Chile and North America. Methods: Using five mitochondrial and three nuclear gene fragments we recovered garli-part maximum likelihood and Bayesian phylogenetic hypotheses for 10 of the 11 extant petaltail species. Biogeographical patterns were analysed using Lagrange and interpreted through beast relaxed clock dating analysis. Results: Petaluridae is monophyletic with an origin in the mid-Jurassic, c. 157 Ma. The family consists of two major clades: one with a Laurasian distribution containing the genera Tachopteryx and Tanypteryx, and another containing the genera Petalura, Phenes and Uropetala, distributed in Gondwanan remnants. Based on our beast molecular clock, these two clades separated c. 146 Ma. Species ages in Petaluridae range from c. 100 to c. 30 million years, with the majority of the species persisting for 70-75 million years. Analysis with Lagrange points to an origin for the family associated with New Zealand, with subsequent dispersal to other Gondwanan remnants (Australia and Chile) as well as Laurasia (eastern and western North America) and subsequent dispersal from western North America to Japan. Main conclusions: The extant species of Petaluridae are extremely old, with most species persisting as independent lineages since the Jurassic. Our results suggest that New Zealand was close to the origin point in the Jurassic; one possibility is that Antarctica was at the centre of the petalurid distribution, based on Permian fossil evidence. Such long persistence for species is surprising, especially considering the specialized habitat required by petalurid larvae; unlike the majority of modern dragonflies, which spend their larval stage in ponds or streams, petaltails live in fen habitats. Petaltails also take multiple years to develop from egg to adult, another trait uncommon in modern dragonflies. Specialization in a species is normally associated with higher extinction rates; the petaltails appear to be an exception to this rule. © 2014 John Wiley & Sons Ltd. Source

The generic names Afroaeschna, Pinheyschna and Zosteraeschna are introduced for 3 groups of Afrotropical dragonfly species, traditionally assigned to the paraphyletic taxon Aeshna. The phylogenetic relationships of these monophyla which are not immediately related to each other are discussed. The Ethiopian populations of Pinheyschna gen. n. are described and characterized as a new sp. (Pinheyschna waterstoni). Zosteraeschna ellioti (Kirby, 1896) and Z. usambarica (Förster, 1906) are regarded as distinct species. Only synonymy, information on status (if feasible) and distribution are given for the remaining species of the group, and a preliminary key to the adults of all but one species is presented. Source

A new species of the endemic New Guinean genus Lanthanusa is described from the Trauna River Valley in Western Highlands Province, Papua New Guinea. Characters of the male are illustrated and affinities of the new species are discussed. Some characters of the type species of Lanthanusa, L. cyclopica, are reassessed and a revised key to the genus is presented.http://www.zoobank.org/urn:lsid:zoobank.org:pub:1F0348AC-4486-49A2-8BA6-AFCE7C1DED9C. © 2014, © 2014 Worldwide Dragonfly Association.

An overview of the genus Teinobasis on the Bird's Head Peninsula and the Raja Ampat Islands in Indonesia is given. Four new species, T. aquila, T. lieftincki, T. michalskii, and T. splendens, are described from the area and one probably new species is described but left unnamed. New material of six other species, T. buwaldai, T. pretiosa, T. pulverulenta, T. rufithorax, T. cf. superba, and T. wallacei, is brought on record. A key to the males of the twelve species known from the region is included and colour illustrations of males of eight species and females of five species are given. Source
