The exoskeleton of the female genitalic region in Phenes raptor is described based on light microscopy and scanning electron microscopy. It is shown that in this species the pattern of sclerites, articulations, processes, and apodemes is overall the same as i n other ovipositor-bearing Odonata, i.e. Zygoptera, the anisozygopteran Epiophlebia, and the anisopteran Aeshnidae. However, many morphological details differ among all these taxa. Fifty-four characters were scored for P. raptor in order to be included in a previously compiled dataset for phylogenetic analysis of ovipositor-bearing Odonata. These characters include only few specific similarities between P. raptor and either Aeshnidae or Epiophlebia. Instead, P. raptor shows a number of features that are unique among ovipositor-bearing Odonata. Absence of serration on the ovipositor inP. raptor and reduction of the interlocking mechanism connecting the two first valves medially is probably correlated with the endosubstratic egg-laying of the female. The ovipositor bears numerous sensilla of different shape, which probably detect suitable places for oviposition. © 2011 Worldwide Dragonfly Association.

The mayfly fauna of Madagascar is highly diverse and largely endemic. Many species remain undescribed, and many species are known from only the larval or adult life stage. The high biodiversity in Madagascar and in other areas has led to an increasing reliance on DNA-based approaches to taxonomy, i.e., to define species boundaries and to associate different developmental stages. We used the general mixed Yule-coalescent (GMYC) model to combine population-and species-level sequence variation of mitochondrial deoxyribonucleic acid (mtDNA) to detect species boundaries in Baetidae mayflies (Ephemeroptera). Starting with a database of 240 sequences (57 species), significant clustering of newly sequenced larvae allowed us to establish 1 new species and 1 new combination and to associate adult and larval stages for both. A molecular phylogeny using additional nuclear (18S) and mtDNA (rrnS, rrnL) gene regions recovered the new species and new combination as a monophyletic group, distinct from other Afrotropical lineages. Therefore, we established a new genus, Adnoptilum, endemic to Madagascar. Adnoptilum gen. n. can be distinguished from other species in both the imaginal and adult stages and appears to belong to the Bugilliesia complex. We conclude that routine sampling of population-and species-level genetic diversity, combined with coalescent-based methods of species delineation, has great potential to become a standard procedure for the study of poorly known taxonomic groups. © 2010 The North American Benthological Society.

Based on re-examination of material belonging to the Museum of Zoology, Hamburg University, Germany, especially Georg Ulmer's collection, as well as newly collected specimens from the Sunda Islands, the genuine concept of Compsoneuria Eaton, 1881 is revised. The genus has had as junior synonyms Compsoneuriella Ulmer, 1939 (Oriental) and Notonurus Crass, 1947 (Afrotropical). A recent molecular study removed Notonurus from this synonymy. The type spe-cies of Compsoneuria, Compsoneuria spectabilis Eaton, 1881, is redescribed. A lectotype male imago is designated for Compsoneuriella thienemanni Ulmer, 1939, type species of Compsoneuriella. Based on egg morphology, nymphal stages of both Compsoneuria and Compsoneuriella are unequivocally attributed. The nymph of Compsoneuria spectabilis is de-scribed and corresponds in part to what Ulmer (1939) described as the nymph of Compsoneuriella thienemanni. The latter nymph is also redescribed from material collected recently in Sumatra. Due to the important number of morphological differences between these two species, Compsoneuriella stat. prop. is removed from its synonymy with Compsoneuria. Besides C. thienemanni, the genus Compsoneuriella encompasses C. langensis (Braasch & Boonsoong, 2010) comb. nov. from Thailand and C. tagbanua (Braasch & Freitag, 2008) comb. nov. from the Philippines (Palawan), which is partially redescribed. All other species under the combined concept of Compsoneuria/Compsoneuriella are mentioned and their generic placements are discussed. The new combination Afronurus taipokauensis (Tong & Dudgeon, 2003) comb. nov. from Hong Kong, China is proposed. Copyright © 2014 Magnolia Press.

In the first ever systematic genetic survey, we have used rigorous decontamination followed by mitochondrial 12S RNA sequencing to identify the species origin of 30 hair samples attributed to anomalous primates. Two Himalayan samples, one from Ladakh, India, the other from Bhutan, had their closest genetic affinity with a Palaeolithic polar bear, Ursus maritimus. Otherwise the hairs were from a range of known extant mammals. © 2014 The Author(s) Published by the Royal Society. All rights reserved.
Ryutaro Goto, postdoctoral fellow in Museum of Zoology and Department of Ecology and Evolutionary Biology, University of Michigan, and Hiroshi Ishikawa, amateur malacologist in Japan, have their paper, describing the new species, published in the open access journal ZooKeys. The new species, named Borniopsis mortoni (Galeommatoidea), was discovered in mudflats at the mouth of the Souzu River, southwestern Shikoku Island, Japan. This bivalve has tiny brownish shells (up to 4.1 mm in length). The species lives attached by both its foot and byssal threads to the body surface of the earthworm-like sea cucumber Patinapta ooplax (Synaptidae). Individuals of B. mortoni are often found on the same host, yet sometimes there could be more than 10 individuals existing side-by-side. The new species is dedicated to a famous British malacologist Brian Morton, emeritus professor of University of Hong Kong. He has described many interesting Pseudopythina species from mudflats in Hong Kong, now assigned to the genus Borniopsis. Host sea cucumbers burrow in mudflats. Most likely, the B. mortoni bivalve uses the host burrows as shelter from predators. The new species is one of the smallest species in this genus. With the burrow of the host sea cucumber being very narrow, the small body size of B. mortoni is probably a corresponding adaptation.
