A New Species

The family Pleidae is represented in Australia only by members of the genus Paraplea. Paraplea brunni (Kirkaldy, 1898) has a widespread distribution in Australia and is also known from New Guinea. Paraplea halei (Lundblad, 1933) appears to be an endemic species occurring only in the southeastern part of Australia. The widespread species P. liturata (Fieber, 1844) occurs in Australia but only in the Northern Territory and Western Australia. The description of P. bifurcata n. sp. documents a fourth pleid species, being known only from the Northern Territory. Paraplea bifurcata n. sp. is easily differentiated from other species of Paraplea by having a bifurcated abdominal keel. An identification key and discussion of morphological characters of the four species of Paraplea from Australia is given.

A New Species

Representatives of some poorly known spider species collected in the rainforest litter of the Orchid Island (Taiwan) are illustrated and discussed here. A new species, Brignoliella tao sp. nov. (Fam. Tetrablemmidae), endemic to Orchid Island, is described based on both sexes. The previously unknown female of Theridiosoma triumphale Zhao & Li, 2012 (Fam. Theridiosomatidae), is described for the first time. Zoma taiwanica (Zhang, Zhu & Tso 2006) comb. nov., from the same family, is illustrated and its transfer from the genus Theridiosoma O. Pickard-Cambridge, 1879 to Zoma Saaristo, 1996 is proposed on the basis of morphological characters. Habitus and genitalia of the endemic species Gongylidioides angustus Tu & Li, 2006 (Fam. Linyphiidae) are also illustrated.

A new species of the family Agnaridae, Lucasioides altaicus sp. nov., is described from the Altai Mountains, southwestern Siberia, based both on morphological characters and molecular data. This species is the first record of Lucasioides from Russia, whose location is the northernmost habitat of terrestrial isopods in indigenous habitats presently known to Eurasia. The diagnostic characters of the new species and a preliminary phylogenetic analysis within Agnaridae are provided.

AbstractThe new corticolous lichen fungus Platythecium seychellense is described from the Seychelles. Morphological characters as well as distribution and resemblance to related species are discussed. The species is characterized by a crustose, grey-green, smooth thallus lacking lichen substances, elongate and slender apothecia having flat, red-brown discs and grey 3-septate ascospores. A world key to all currently known species in the genus is presented.

A New Species

Morphological characters support the description of a new species of Passifloraceae from Mayotte Island: Adenia barthelatii M. Pignal, Yockteng, Hearn & Labat. Morphological and molecular data suggest that A. barthelatii belongs to the ‘warty-gland’ subclade of Clade V defined by Hearn elsewhere. Since the warty-gland clade is restricted to the Malagasy region we suggest a Malagasy origin of this Maorian species of Adenia.

A New Species

The classification of the Trematode family Opisthorchiidæ presents some difficulties to the systematist. These difficulties arise partly from the fact that a number of the existing species appear to lack any real morphological characters by which they can be differentiated, slight variations in measurements, together with a difference in host, having been considered sufficient to justify the making of new species. This view has resulted in the placing of undue importance on somewhat minor differences when they do occur in other species, such differences being considered sufficient for creating new genera.The systematist is further confronted with the difficulty of forming definite opinions on the systematic position of some of the species made by earlier workers. Their descriptions and figures are often inadequate owing to the fact that characters which, in the past, were considered of minor importance are now given much closer attention. Examples of the confusion which has arisen from such a position will be referred to in this paper.

A New Species

A new species of the family Planorbidae is described from the land thermal spring Khakusy, on the north-eastern shore of Lake Baikal. The description of Gyraulustakhteevi sp. n. includes morphological characters and gene sequences (COI of mtDNA) for the species separation from sister taxon Gyraulusacronicus (A. Férussac, 1807) collected from the small Krestovka River in-flowing into the south-western part of the Lake. The new species differs from G.acronicus in small shell size of adults, having smaller number of prostate folds (maximal up to 26 in G.takhteevi n. sp. vs. 40 in G.acronicus), a short preputium (approximately twice shorter than the phallotheca), and an elongated bursa copulatrix. The population of Gyraulustakhteevi sp. n. consists of two co-existent morphs: one of them has a narrow shell spire and the second is characterized by wide spire similar to the shell of G.acronicus. One of the two revealed haplotypes of the new species includes both morphs, while the second consists of snails with wide spired shells.

A new mite species, Riccardoella (Proriccardoella) tokyoensis n. sp., is described from the lungs of the terrestrial gastropod Tauphaedusa tau (Boettger, 1877) (Clausliidae) collected in a forest city park of Tokyo, Japan. The new species is distinguished from other Riccardoella species by the following morphological characters: tibia II bears 2 setae (vs. 3 setae in other species); femur I bears 5 setae (vs. 4 or 6 setae in other species); seta of trochanter I is absent (vs. 1 seta in other species). Our phylogenetic tree based on amino acid sequences of the mitochondrial cytochrome c oxidase subunit 1 (COX1) confirmed that another member of the family Ereynetidae, “Ereynetidae sp.”, is the closest relative with 85% sequence identity.

AbstractEctoparasitic nematodes (Acugutturus, Vampyronema and Noctuidonema) of the family Acugutturidae from 13 species of Lepidoptera (moths) and one species of Blattodea (cockroaches) were collected, measured and analysed by discriminant analysis in order to identify conspecifics and to determine which morphological characters were useful in defining differences between nematodes on different host species. The position of the excretory pore posterior to the metacorpus clearly differentiates Acugutturus parasiticus from Noctuidonema and Vampyronema. Two populations of A. parasiticus on Periplaneta americana from the West Indian islands of St Lucia and Guadeloupe are conspecific. Nematodes resembling Vampyronema, collected from two genera of Sphingidae in Guadeloupe are characterised by extremely long stylets, equal to ca 37% of the body length, and may represent a new genus. Noctuidonema from four species of Spodoptera (Noctuidae) are conspecific. However, a somewhat different Noctuidonema from the noctuid Pseudaletia unipuncta may represent a new species, based primarily on its shorter stylet length. Simple spicule structure, a smaller V percentage, and a shorter stylet in Vampyronema are characters that best define its differences from Noctuidonema. Nematodes on the noctuids Anicla infecta and Eulepidotis addens probably represent two new species of Vampyronema. There was no clear differentiation between nematodes on the noctuids Mocis disseverans, M. latipes, Agrapha oxygramma and Orthodes crenulata, and they are all probably conspecific with V.dibolia. Thus far, Noctuidonema has been found only on the trifine noctuids Spodoptera and Pseudaletia, whereas Vampyronema has been found on both trifine and quadrifine noctuids. We found evidence for sequential evolution, but not co-evolution, between these ectoparasitic nematodes and their lepidopteran hosts.
