AbstractAdults and deutonymphs of Najadicola ingens (Koenike) are redescribed and larvae are described for the first time. In light of larval, deutonymphal and adult character states, the phylogenetic relationship of Najadicola with genera in the families Pionidae and Unionicolidae is re-evaluated and transfer of the subfamily Najadicolinae to Pionidae is proposed. Original life history information is presented to supplement existing literature. Parasitism by larval N. ingens on an adult chironomid of the genus Polypedilum is reported. The unique behavioural and morphological characteristics of members of Najadicola suggest that mussel parasitism evolved independently from a parallel adaptive sequence in the genus Unionicola.

We report five alien ascidians with some distinct features that were investigated from August 2009 to October 2011 in Korea, among which Ascidiella aspersa (Müller, 1776) belonging to family Ascidiidae of order Phlebobranchia and Molgula manhattensis (De Kay, 1843) belonging to family Molgulidae of order Stolidobranchia are newly discovered invasive species. These ascidians were identified and their phylogenetic relationships were clarified through molecular analysis using about 680 bp of nuclear 18S rDNA and about 670 bp of mt-COI genes along with detailed morphological characteristics, and reported for the first time in Korea. It was discovered that A. aspersa was widespread three coastlines of Korea except Jeju Island, and M. manhattensis first found in Mokpo, Gunsan, and Incheon in June 2010 extended into Busan of Korea Strait in 2011.

Working Out

The writer has been working on the food plants of the leaf-hoppers for many years and has found in the main the different species of the genus Platymetopius, as commonly recognized, are very closely confined to a single species of plant or to a closely related group. Before it was possible to prepare a list of the food plants in the group it was found necessary to describe a number of new species of which food plant and life history information was available. In working out the relationship of these species, two startling discoveries were made.

The family Salifidae is a predaceous leech taxon in the suborder Erpobdelliformes. Although Salifidae is widely distributed in the African, Oriental, Indo-Malayan, Sino-Japanese and Australasian regions, the phylogenetic relationships of the family Salifidae have never been tested using molecular data obtained from leeches collected from the family distributional range. A salifid species was collected for the first time in Vietnam, and relevant morphological and molecular data are presented here. Because the Vietnamese salifid species possesses unique morphological characteristics among the known salifid species, this species is herein described as a new species, Salifa motokawai, sp. nov. Phylogenetic analyses based on nuclear 18S rRNA and histone H3, as well as mitochondrial cytochrome c oxidase subunit I, tRNACys, tRNAMet, 12S rRNA, tRNAVal, 16S rRNA, tRNALeu and NADH dehydrogenase subunit 1 markers demonstrate that the Vietnamese salifid species is a close congener with the African Salifa perspicax and the Malagasy Linta be. Furthermore, molecular data revealed non-monophyly of the Asian salifid leeches. According to the observed phylogenetic relationships and morphological characteristics of the Vietnamese Salifa motokawai, sp. nov., the current classification of salifid taxa should be revised.

A review and cladistic analysis of the genus Ptychoderes Schoenherr, 1823 is presented. The genus and the following seventeen known species are redescribed: P. nebulosus (Olivier, 1795) (type species), P. elongatus (Germar, 1824), P. viridanus Boheman, 1833, P. virgatus Fåhraeus, 1839, P. obsoletus Jekel, 1855, P. depressus Jekel, 1855, P. mixtus Jekel, 1855, P. callosus Jekel, 1855, P. antiquus Jekel, 1855, P. brevis Jordan, 1894, P. longicollis Jordan, 1894, P. bivittatus Jordan, 1894, P. rugicollis Jordan, 1895, P. jordani Frieser, 1959, P. crustatus Frieser, 1988, P. magnus Mermudes & Napp, 2004 and P. jekeli Mermudes & Napp, 2004. New synonyms are proposed: Ptychoderes nebulosus (Olivier, 1795) = Ptychoderes tricostifrons Fåhraeus, 1839 syn. nov. = Ptychoderes columbianus Jekel, 1855 syn. nov.; and Ptychoderes antiquus Jekel, 1855 = Ptychoderes affinis Jordan, 1894 syn. nov. A key to species and maps of their geographical distribution are provided. The cladistic analysis with 24 taxa and 50 characters from body vestiture, external morphology, wing venation, male and female terminalia and rectal loop, resulted in a single cladogram showing, for the first time, a hypothesis of phylogenetic relationship  among genera of Anthribinae. The analysis included the seventeen species of Ptychoderes, as defined in the taxonomic review, along with the type species of the genera presently considered as belonging to Ptychoderini Jekel, 1855: Cerambyrhynchus schoenherri Montrouzier, 1855, Phloepemon acuticornis (Fabricius), Phloeotragus heros (Fabricius), Tribotropis prasinata (Fåhraeus, 1839), Hypselotropis annulicornis (Fåhraeus, 1839) and Unanthribus maximus Mermudes, 2003. A hypothesis of the phylogenetic relationships among the Neotropical genera of Ptychoderini is presented in parenthetical notation: ((Tribotropis + Hypselotropis) (Unanthribus + Ptychoderes)). The monophyly of Ptychoderes is supported by 14 synapomorphies and its interrelationships are as follows: ((P. crustatus (P. brevis + P. jekeli)) ((P. longicollis (P. jordani (P. obsoletus+P. magnus) (P. depressus+P. virgatus))) (P. mixtus (P. bivittatus ((P. callosus+P. rugicollis) (P. viridanus (P. antiquus (P. elongatus+P. nebulosus)))))))).

A New Species

A new species of rust fungus, Puccinia marrubii sp. nov. is described from Turkey. The new species is the first Puccinia species to be identified on genus Marrubium (Lamiaceae). In order to determine the phylogenetic relationships of the new species, ITS region was amplified by PCR, sequenced, and analyzed. In addition to the ITS region of seven Puccinia species, P. annularis, P. jasmini, P. malvacearum, P. nigrescens, P. phlomidis, P. salviae, and P. serpylli were sequenced for the first time. Phylogenetic analyses performed by using distance, Bayesian methods confirmed that the new rust was closely related to P. serpylli, P. malvacearum, P. salviae, and P. annularis. The diagnostic morphological characteristics of the new species were discussed with the phylogenetically related species.

A phylogenetic analysis was conducted to address evolutionary relationships among the earliest members of the Miacidae (one of two early Cenozoic carnivoran families) and to ascertain the position of an ambiguous taxon, “Miacis” jepseni, with respect to the genera Miacis, Uintacyon, Vulpavus, Vassacyon, and Oödectes. The results of this analysis indicate that “Miacis” jepseni should be referred to the genus Oödectes, and both genus and currently included species are rediagnosed. The phylogenetic relationship of Oödectes to other miacids, and relationships among early Eocene miacids more generally, however, are less well resolved. Support is found for sister taxon relationships between Miacis and Vulpavus and between Uintacyon and Vassacyon, and it is suggested that this latter clade is the sister taxon to all other members of Miacidae.

Abstract The sexual morph (chasmothecium) of Erysiphe macleayae on Chelidonium majus has been found in Romania for the first time. Although the asexual morph of this powdery mildew on C. majus is known from many countries, the occurrence of chasmothecia on this host is rather rare. A description of morphological characters and an analysis of the phylogenetic relationship of ITS sequences of the Romanian specimens are presented.
