Species delimitation in the Andean grasshopper genus Orotettix Ronderos & Carbonell (Orthoptera: Melanoplinae): an integrative approach combining morphological,molecular and biogeographical data

The reciprocal illumination nature of integrative taxonomy through hypothesis testing, corroboration and revision is a powerful tool for species delimitation as more than one source has to support the hypothesis of a new species. In this study, we applied an integrative taxonomy approach combining molecular and morphological data sets with distributional patterns to examine the level of differentiation between and within the grasshopper Orotettix species. Orotettix was described based on five valid species distributed in the Andes of Peru. In our study, initially a molecular‐based hypothesis was postulated and tested against morphological data and geographical patterns of distribution. Results from molecular and morphological analyses showed agreement among the species delimitation in Orotettix, and were also consistent with the geographical distribution. The analyses allowed us to delimit five new species for the genus ( O. lunatus sp. nov. , O . astreptos sp. nov. , O. colcaensis sp. nov. , O . paucartambensis sp. nov. and O . dichrous sp. nov. ) from the Eastern and Western Cordilleras of Peru. We also provide critical knowledge on the phylogenetic relationships and distribution of the genus and conduct a revision of Orotettix. © 2015 The Linnean Society of London     

On the phylogeny of Ischyroceridae (Amphipoda,Senticaudata, Corophiida), with the description of a new genus and eight new species from deep‐sea Brazilian waters

The family Ischyroceridae is analysed herein by cladistic methods based on morphological characters, using both PAUP 4.0b and TNT. The data matrix of 41 characters × 32 terminal taxa was constructed using DELTA. Based on the results, we comment on the phylogenetic relationships of certain genera and their synapomorphic characters, also discussing the phylogenetic position of M yersius gen. nov. , which appeared as the sister group of Bathyphotis. In addition, Pseudischyrocerus crenatipes is removed to Bathyphotis, for which a new diagnosis is provided. A taxonomic study with the Ischyroceridae collected on the continental slope (depth, 700–2000 m) in the Campos Basin (20.5–24°S, 40–41°W) was also performed. Samples were collected in November–December 2002 and July–August 2003 using a box core device. As a result, a new genus and eight new species are described: B onnierella campensis sp. nov. , B onnierella laurensi sp. nov. , M yersius denticaudatus gen. et sp. nov. , N otopoma lowryi sp. nov. , N otopoma teresae sp. nov. , P seudericthonius bousfieldi sp. nov. , P seudericthonius concavus sp. nov. , and P seudischyrocerus caecus sp. nov. The genus Bonnierella is recorded for the first time from Brazilian waters, and the subspecies Bonnierella linearis linearis and Bonnierella linearis californica are elevated to species rank. Keys to the genera of Ischyroceridae used in the cladistic analysis and the world species of Notopoma are given. © 2014 The Linnean Society of London     

Systematic revision of the genus Everettia Godwin‐Austen, 1891 (Mollusca: Gastropoda: Dyakiidae) in Sabah,northern Borneo

The species of the snail genus Everettia in the Malaysian state of Sabah are superficially similar and difficult to distinguish by their shells. This paper presents new data on the taxonomy and distribution of Everettia in Sabah that have accumulated since the revision by Godwin‐Austen in 1891. By using morphological and molecular phylogenetic approaches, we reveal at least seventeen species of Everettia in Sabah, of which eleven are new to science, namely: Everettia layanglayang sp. nov. , Everettia lapidini sp. nov. , Everettia paulbasintali sp. nov. , Everettia occidentalis sp. nov. , Everettia jasilini sp. nov. , Everettia safriei sp. nov. , Everettia interior sp. nov. , Everettia jucundior sp. nov. , Everettia planispira sp. nov. , Everettia monticola sp. nov. , and Everettia dominiki sp. nov. , and one new subspecies, namely, Everettia corrugata williamsi ssp. nov. Phylogenetic analysis of mitochondrial COI and 16S, and nuclear ITS‐1 sequences demonstrates the monophyly of most of the morphologically well‐defined species. Our results show that certain aspects of classical morphology‐based taxonomy for Everettia species, especially with regard to the unique combination of shell surface sculptures, animal head colour, and mantle pigmentation, are solid. A dichotomous key to the Sabah species and subspecies of Everettia is provided. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 157 , 515–550.     

Nine new and less known nematode species from the deep-sea benthos of the Norwegian Sea

Eight new and one less known nematode species are described from Vöring Plateau at 970 m to 1426 m depth and adjacent deep-sea plain at 3062 m depth in the Norwegian Sea: Actinonema grafi sp. nov., Desmodora pilosa Ditlevsen, 1926, Leptolaimus meyer-reili sp. nov., Tarvaia heegeri sp. nov., Diplopeltoides linkei sp. nov., Diplopeltis bathmanni sp. nov., Southerniella nojii sp. nov, Pararaeolaimus rumohri sp. nov. and Theristus altenbachi sp. nov. Differential diagnoses to the eight new species are given. Actinonema grafi, Leptolaimus meyer-reili and Theristus altenbachi are frequently found on Vöring Plateau and belong to the most dominant species, whereas Desmodora pilosa and Pararaeolaimus rumohri are dominant species at few sites only. The other species occur sporadically, in few numbers, and belong — as do Pararaeolaimus rumohri — to seldomly reported nematode genera.Contribution No. 111 from Sonderforschungsbereich 313 der Universität Kiel, Germany.

Cladistic analysis and taxonomic revision of the genus Karos Goodnight & Goodnight, 1944 (Opiliones,Laniatores, Stygnopsidae)

A cladistic analysis of the genus Karos Goodnight & Goodnight, 1944, was performed using morphological data of the somatic and male genitalia characters. The analysis included 23 terminal taxa, including nine of the 11 described species of the genus plus nine new species according to the previous generic diagnosis and five species as outgroups. According to the topologies obtained by parsimony analyses, the genus is a paraphyletic assemblage, referred here as the Karos genus‐group. Therefore, the genus Karos is rediagnosed here and now includes seven species: Karos barbarikos Goodnight & Goodnight, 1944 (type), Karos parvus Goodnight & Goodnight, 1971, Karos projectus Goodnight & Goodnight, 1971, K aros hexasetosus sp. nov. , K aros monjarazi sp. nov. , K aros singularis sp. nov. , and K aros tersum sp. nov. The genera Monterella Goodnight & Goodnight, 1944, Montabunus Goodnight & Goodnight, 1945, Chapulobunus Goodnight & Goodnight, 1946, and Potosa Goodnight & Goodnight, 1947 are revalidated, rediagnosed, their respective type species are redescribed and the following species are described: Chapulobunus poblano sp. nov. and Potosa reddelli sp. nov. The genera Crettaros gen. nov. , Huasteca gen. nov. , and Mictlana gen. nov. , and the following species are described: Crettaros santibanezi sp. nov. (type), Crettaros valdezi sp. nov. , and Huasteca silhavyi sp. nov. The following new combinations are proposed: Huasteca gratiosa (Goodnight & Goodnight, 1971) comb. nov. (type), Huasteca rugosa (Goodnight & Goodnight, 1971) comb. nov. and Mictlana inops (Goodnight & Goodnight, 1971) comb. nov. (type). Karos brignolii ?ilhavý, 1974, is considered a junior synonym of Huasteca rugosa. Finally, ‘Karos’ depressus Goodnight & Goodnight, 1971 is considered incertae sedis until adult males can be studied. Diagnoses of the Karos and Paramitraceras genus‐groups, and an identification key to the eight genera and 19 species of the former are provided. © 2015 The Linnean Society of London

Megapanorpa,a new genus with a single anal horn in males from Oriental China (Mecoptera: Panorpidae)

A new genus of Panorpidae, Megapanorpa gen. nov. , is erected for five new species, Megapanorpa grandis sp. nov. (type species), M. absens sp. nov. , M. gaokaii sp. nov. , M. jiangorum sp. nov. and M. wanghongjiani sp. nov. This genus is similar to Cerapanorpa Gao et al., 2016 in a single anal horn on the sixth tergum of male, but can be differentiated from the latter by the following characters: the seventh abdominal segment of male is constricted and stalk‐like at base, the subgenital plate of female with a pair of lateral plates, and the medigynium of female with a concealed axis. Keys to genera of Panorpidae and species of Megapanorpa gen. nov. are presented. The morphology and function of anal horns in different genera and species have been discussed.

The genus Amraica Moore, 1888 in China is reviewed. In addition to the four species and three subspecies already known, one new species, A. prolata sp. nov. is described and one newly recorded species, A. ferrolavata ( Walker, 1863 (imprint 1862) ) is redescribed. The generic characters, based on all species, are summarized. Illustrations of external features and genitalia are presented.     

Revision and phylogenetic assessment of the rove beetle genus Pseudohesperus Hayashi,with broad reference to the subtribe Philonthina (Coleoptera: Staphylinidae: Staphylinini)

This paper studies the phylogeny of the rove beetle subtribe Philonthina, to test its hypothetical monophyly and to unravel the evolutionary relationships of the subtribe and its included genus‐level taxa, with emphasis on the genus Pseudohesperus and its close‐allied relatives. The phylogenetic analyses are based on 105 adult morphological characters and 66 terminal taxa, i.e., all six members of Pseudohesperus, 51 species to represent 29 other genera of the subtribe Philonthina, seven species to represent the other six subtribes of Staphylinini, one species of the tribes Arrowinini, and one of the Platyprosopini. According to the phylogenetic results obtained, the genus Erichsonius should move out from the hitherto‐defined subtribe Philonthina and thus the monophyly of this taxon is challenged. The phylogenetic tree suggests that the genera Hesperus and Belonuchus might not be monophyletic, but the monophyly of Pseudohesperus and the sister relationship between it and Bisnius are well supported. The species‐level phylogenetic relationships of the genus Pseudohesperus reveal a clear pattern of species diversification that can be correlated well with the species' zoogeographical patterns. The paper also revises the taxonomy of Pseudohesperus and describes five new species from China: Pseudohesperus luteus Li & Zhou sp. nov. , Pseudohesperus pedatiformis Li & Zhou sp. nov. , Pseudohesperus tripartitus Li & Zhou sp. nov. , Pseudohesperus sparsipunctatus Li & Zhou sp. nov. , and Bisnius lubricus Li & Zhou sp. nov. An identification key to the species of Pseudohesperus is provided and their geographical distributions are mapped. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163 , 679–722.
