Taxonomy and phylogeny of Lineus torquatus and allies (Nemertea,Lineidae) with descriptions of a new genus and a new cryptic species

The heteronemertean genus Lineus Sowerby, 1806 has been badly in need of revision because of its apparent non-monophyly. In this paper, we focus on Lineus torquatus Coe, 1901, one of the heteronemertean species that occur commonly in waters around the North Pacific, as well as a few other allied species distributed in the western North Pacific, including Lineus alborostratus Takakura, 1898 and Cerebratulus montgomeryi Coe, 1901. Based on phylogenetic analyses using 16S, COI, 28S, 18S, and H3 gene and ITS sequences, we detected a well-supported clade comprised of heteronemerteans with a frontal white band on the head, to which we add Kulikovia gen. nov. This genus is nested within a more comprehensive, highly supported clade, here named the Siphonenteron-clade, which contains Tenuilineus bicolour (Verrill, 1892), Lineus flavescens Coe, 1905, Siphonenteron bilineatum (Renier, 1804), S. cf. bilineatum, Lineus cf. caputornatus, and Lineus sp. from Guam. Our analyses confirmed the presence of a cryptic species of what was formerly known as the cherry-red and reddish forms of Lineus torquatus, herein described as Kulikovia manchenkoi sp. nov. based on some external characters, internal morphology, and the four genetic markers (COI, 16S, H3, and ITS). In contrast to the species pair K. torquata–K. manchenkoi, the reddish form of K. alborostrata does not differ genetically from the typical form of this species. The significance of the external and internal characters for distinguishing cryptic species is discussed.

The freshwater crab fauna (Crustacea: Brachyura) of the Philippines. V. On a new genus and species of potamid from Palawan island, Philippines

A new genus and new species of terrestrial potamid crab ( Carpomon pomulum) is described from the island of Palawan in the Philippines. This new genus can easily be distinguished from all other Philippine potamids in its smooth and inflated carapace, no trace of an epibranchial tooth, extremely low postorbital cristae, and stout and twisted male first gonopod. This revised version was published online in July 2006 with corrections to the Cover Date.     

Morphology and infraciliature of two new marine urostylid ciliates: Metaurostylopsis struederkypkeae n. sp. and Thigmokeronopsis stoecki n. sp. (Ciliophora, Hypotrichida) from China

ABSTRACT. The morphology and infraciliature of two new marine urostylid ciliates, Metaurostylopsis struederkypkeae n. sp. and Thigmokeronopsis stoecki n. sp., collected from the coastal waters off Qingdao (Tsingtao), China, have been investigated. Metaurostylopsis struederkypkeae n. sp. is characterized by the slender body shape, small size, rose-reddish cell colour, and having two kinds of pigment-like granules. The larger pigment-like granules are yellow–green or grass-green in colour, oval in shape, and flattened, whereas the smaller ones are wine-reddish. Infraciliature and nuclear apparatus are similar to the well-known Metaurostylopsis marina. Thigmokeronopsis stoecki n. sp. is characterized by its large size with dark brown cell colour and grass-green cortical granules, which are large, blood-cell shaped, and sparsely distributed. The thigmotactic ciliature is conspicuous: 11–14 rows of densely arranged cirri occupy the most postoral area. Keys are provided for all the known species in both genera.     

A new genus and species of Metopiinae (Hymenoptera, Ichneumonidae) from Mexico

A new genus of Metopiinae, Ojuelos Khalaim, gen. n., with a single species, Ojuelos juachicus Khalaim & Ruíz-Cancino, sp. n., is described from Jalisco Province in central Mexico. Ojuelos belongs to the group of three genera (Cubus Townes & Townes, Colpotrochia Holmgren and Triclistus Förster) having a high lamella separating the antennal sockets and reaching the median ocellus (this lamella possesses a dorsal groove in it, just below the median ocellus), but differs from these genera primarily by 1) face and clypeus not convex in lateral view, 2) face separated from clypeus by a shallow transverse impression, 3) mandible with lower tooth very strongly reduced, 4) flagellomeres of antenna strongly transverse, and 5) dorsal carinae of propodeum reduced. A portion of the key to the genera of Metopiinae is provided to distinguish the new genus.     

The Hoosier cavefish,a new and endangered species (Amblyopsidae,Amblyopsis) from the caves of southern Indiana

We describe a new species of amblyopsid cavefish (Percopsiformes: Amblyopsidae) in the genus Amblyopsis from subterranean habitats of southern Indiana, USA. The Hoosier Cavefish, Amblyopsis hoosieri sp. n., is distinguished from A. spelaea, its only congener, based on genetic, geographic, and morphological evidence. Several morphological features distinguish the new species, including a much plumper, Bibendum-like wrinkled body with rounded fins, and the absence of a premature stop codon in the gene rhodopsin. This is the first new cavefish species described from the United States in 40 years and exemplifies how molecular data can alert us to the presence of otherwise cryptic biodiversity.

Smeagolida,a new order of gymnomorph mollusc from New Zealand based on a new genus and species

Abstract

Smeagol manneringi n.gen. & sp. is erected as the only known representative of a new order, Smeagolida, and is compared with existing gymnomorph orders. The relative ranking of Gymnomorpha, Opisthobranchia, and Pulmonata is discussed, and use of the name Systellommatophora is abandoned. The gymnomorph slugs are interpreted as a polyphyletic assemblage of stem euthyneurans, but subclass Gymnomorpha is retained as a convenient grouping.     

Morphological, cytogenetic and allozymic variation within Cephalofovea (Onychophora: Peripatopsidae) with descriptions of three new species

Variation within and between populations of Cephalofovea (Peripatopsidae) has been examined by allozyme, karyological and morphological analyses. Four groups are recognized on the basis of allozyme electrophoresis. One group includes specimens from the type locality of the only described species of the genus, C. tomahmontis. While karyotypic and morphological character states show considerable inter-group variation, the distributions of these states among groups are not concordant when different characters are compared. However, each group of populations is uniquely defined by the full suite of character states it possesses. The four groups are recognized here as distinct species with three species described as new.     

A new genus and species of Macrosiphini (Hemiptera,Aphididae) from China,living on Isodon eriocalyx

The aphid genus Nigritergaphis gen. n. is described, and N. crassisetosa sp. n. on Isodon eriocalyx (Dunn) Kudô (Lamiaceae) from Yunnan, China is described and illustrated. The new species curls and distorts the leaves of this important traditional Chinese medicinal plant, and is evidently specific to this host. Holotype and paratypes are deposited in the National Zoological Museum of China, Institute of Zoology, Chinese Academy of Sciences, Beijing, China.     

A new goby (Teleostei: Gobiidae) from the South China Sea and its significance for gobioid classification

A new genus and species of gobiid fish, Egglestonichthys Patriciae , is described from the South China Sea. Certain features of the modified head lateral-line system resemble those seen in eleotrine genera with 'transverse' suborbital sensory papillae, but the skeleton of the new goby is essentially gobiine. Aspects of the lateral-line system indicate closest relationship with genera from both the IndoPacific area ( Callogobius complex, Psilogobius, Stonogobiops ) and the New World ( Microgobius ). Wider affinities with other gobiine and gobionelline genera are discussed. Discrepancies between arrangements based predominantly on lateral-line characters and on osteology are noted and their implications considered for future classification of the gobioid fishes.     

Phylogeny of Grumichellini Morse, 1981 (Trichoptera: Leptoceridae) with the description of a new genus from southeastern Peru

Osflintia manu, new genus, new species, of long-horned caddisfly (Leptoceridae: Triplectidinae: Grumichellini) is described and illustrated from southeastern Peru. The phylogeny of Grumichellini Morse (Leptoceridae: Triplectidinae) is revisited and hypotheses of homology of some morphological characters are reconsidered. The monophyly of the tribe is corroborated and the phylogenetic relationships of its included genera are inferred to be (Triplexa (Gracilipsodes ((Grumichella, Amazonatolica) (Atanatolica, Osflintia, n. gen.)))) from adult and larval characters. Diagnostic characters of the new genus include the following: reduced tibial spur formula (2, 2, 2), loss of forewing crossvein sc-r1, hind wing discoidal cell closed, hind wing fork IV present, pair of long setae on tergum IX of the male genitalia, and pair of processes on the apex of segment X.
