Discheramocephalini,a new pantropical tribe of featherwing beetles (Coleoptera: Ptiliidae): description of new taxa and phylogenetic analysis

Abstract Two new genera and eight new species of featherwing beetles (Coleoptera: Ptiliidae) possessing a remarkable horizontal perforation of the mesoventral keel are described: Skidmorella vietnamensis sp.n. (Vietnam), S. memorabilis sp.n. (Indonesia), S. serrata sp.n. (Vietnam), Fenestellidium capensis gen. et sp.n. (South Africa, type species), F. kakamegaensis sp.n. (Kenya), Cissidium okuensis sp.n. (Cameroon), Dacrysoma usambarensis gen. et sp.n. (Tanzania, type species) and D. felis sp.n. (Madagascar). A phylogenetic analysis of 24 taxa and 37 parsimony‐informative characters supports the hypothesis of a single origin of the mesoventral perforation, thus uniting Discheramocephalus, Skidmorella, Africoptilium, Fenestellidium, Cissidium and Dacrysoma into a pantropically distributed clade, for which a new tribe Discheramocephalini (type genus Discheramocephalus) is proposed. Identification keys to Discheramocephalini genera and, in some cases, to species are provided. Each new species is illustrated with scanning electron microscopy images.     

Three new species of fleas belonging to the genus Macrostylophora from the three‐striped ground squirrel,Lariscus insignis,in Java

Three new species of fleas belonging to the genus Macrostylophora (Siphonaptera, Ceratophyllidae) are described from the three‐striped ground squirrel, Lariscus insignis, from Tjibodas, West Java (Jawa Barat), Indonesia at an elevation of 1500 m. Macrostylophora larisci sp. n. is described from three male specimens, Macrostylophora debilitata sp. n. is described from one male and Macrostylophora wilsoni sp. n. is described from one female. Non‐genital morphological characters of the female specimen, including ctenidial spine shapes and lengths, show that it is not the corresponding female for either M. larisci sp. n. or M. debilitata sp. n. It is unusual for three different species of congeneric fleas to parasitize the same host species in the same geographical location. These three new species represent the first known records of Macrostylophora from Java and they could be enzootic vectors between rodents of flea‐borne zoonotic pathogens such as Rickettsia typhi and Yersinia pestis, both of which are established on Java. A list is provided of the 43 known species and 12 subspecies of Macrostylophora together with their known geographical distributions and hosts. A map depicting the distributions of known Indonesian (and Bornean) species of Macrostylophora is also included.     

Phylogeny of a new supertribe Cephenniitae with generic review of Eutheiini and description of a new tribe Marcepaniini (Coleoptera: Staphylinidae: Scydmaeninae)

Genera of Eutheiini are reviewed and Eutheimorphus is removed from this tribe of ant‐like stone beetles (Scydmaeninae) and transferred to Cephenniini. A monogeneric Marcepaniini trib.n. is described to accommodate Marcepania gen.n. from Malaysia, with five species: M. semengohensis sp.n. (the type species of Marcepania), M. tuberculata sp.n. , M. seramaensis sp.n. , M. minutissima sp.n. and M. elongata sp.n. A phylogenetic analysis of all genera of Cephenniini, Eutheiini and Marcepaniini based on adult morphological characters resulted in recovering a well‐supported monophyletic clade Eutheiini + (Marcepaniini + Cephenniini) and these tribes are included in Cephenniitae stat.n. (Eutheiini and Cephenniini are therefore removed from Scydmaenitae). Only a weak support for monophyly of Eutheiini was found, but morphological characters allow for maintaining this presumably relic group as a separate tribe. Previously proposed monophyletic groups within Cephenniini were recovered as such, but after inclusion of Eutheimorphus, a sister taxon to the ‘Cephennomicrus group’, the latter lineage gained weak statistical support. The evolutionary history of Cephenniitae is discussed, with focus on known northern hemisphere fossils classified in Scydmaenitae and Hapsomelitae, but possibly closely allied to Cephenniitae. Establishing the supertribe Cephenniitae is the first step toward a profound reclassification of Scydmaeninae on a robust phylogenetic basis.

A new scolenaspidid (Osteostraci, Vertebrata) from the Lower Devonian of Podolia, Ukraine

Anew osteostracan genus and species,Victoraspis longicornualis n. gen., n. sp., is described based on material from Rakovets’, present day Ukraine. This new taxon shares characters with the two generaStensiopelta Denison, 1951 andZychaspis Janvier, 1985. A phylogenetic analysis supports the position ofVictoraspis as the sister group to a monophyleticStensiopelta, while the interrelationships of the various species ofZychaspis are poorly resolved. A morphometric analysis is carried out in an attempt to further resolve the taxonomic affinity. This analysis groups all examinedZychaspis species closely together, and further supports the establishment ofVictoraspis as separate genus.      

A cladistic analysis of Erythracarinae (Acarina: Prostigmata: Anystidae), with the description of a new genus

A cladistic analysis of sixty erythracarine species is presented and used to justify recent nomenclatorial changes to the classification of erythracarine genera. Erythracarinae is redescribed, and a new diagnosis for the subfamily and a key to the included genera are presented. Neotarsolarcus is recognized as a junior synonym of Tarsolarkus, which is recorded for the first time from North America. A new genus, Pedidromus, with six new species (P. agitatus sp.n. P. curiosus sp.n., P. durongensis sp.n., P. peliculus sp.n., P. pilotrix sp.n., P. velox sp.n.) is described.     

Albuca annulata sp. nov. (Hyacinthaceae) from the Albany Centre of Endemism,South Africa

Within the context of a revision of Albuca, a new species, here described as Albuca annulata Mart.‐Azorín & M. B. Crespo sp. nov., was found in three populations in the Albany Centre of Endemism, Eastern Cape, South Africa. This new species is closely related to Albuca bakeri Mart.‐Azorín & M. B. Crespo and A. caudata Jacq., but it can be clearly differentiated by floral and vegetative characters. Data on morphology, ecology and distribution are reported for this new species. Affinities and divergences with other close allies are also discussed.     

A revision of Platybothrium Linton, 1890 (Tetraphyllidea: Onchobothriidae), with a phylogenetic analysis and comments on host-parasite associations

A revision of Platybothrium Linton, 1890 is presented, based on available type and voucher material, as well as extensive new collections from elasmobranchs belonging to the Carcharhinidae (requiem sharks) and Sphyrnidae (hammerhead sharks). All 10 nominal Platybothrium species are treated or redescribed herein. Four of these 10 nominal species, in addition to one former member of Dicranobothrium Euzet, 1953, are considered valid members of Platybothrium. Five new Platybothrium species are described: P. angelbahiense n. sp. ex Carcharhinus leucas, P. coshtaprum n. sp. ex C. plumbeus, P. jondoeorum n. sp. ex Negaprion acutidens and C. melanopterus, P. kirstenae n. sp. ex C. obscurus, and P. tantulum n. sp. ex Sphyrna lewini and S. zygaena. Sixty-three morphological characters were employed in cladistic analyses of nine Platybothrium species and five outgroup species. Coding and analysis strategies were varied to assess the effects of coding inapplicable characters as missing or as a separate character state, and of excluding characters for which data are missing in more than 10% of the taxa. The analysis in which inapplicable characters were coded as a separate character state and no characters were excluded produced the best-supported and most conservative estimate of the interrelationships of Platybothrium spp. Platybothrium appears to be a monophyletic assemblage, with the most basal species being P. spinulifera Southwell, 1912. The group of species possessing an accessory piece between the hooks forms a clade within the genus. Species lacking an accessory piece, which had previously been placed in Dicranobothrium Euzet, 1953, do not appear to be each other's closest relatives; thus, Dicranobothrium is considered a synonym of Platybothrium. An examination of host associations indicated that Platybothrium species are broadly distributed among, and entirely restricted to, carcharhinid and sphyrnid shark species. Most Platybothrium species exhibit oioxenous host-specificity, with all but two species each parasitising only a single host species. In several host species, multiple Platybothrium congeners parasitise the same host individual, a phenomenon not previously reported for Platybothrium.     

A new genus and a new species of Akicerinae (Orthoptera: Acridoidea: Pamphagidae) from Libya

A new genus, Neotmethis gen. n., with a new species, Neotmethis bidentatus sp. n., from the Fezzan Province of Libya is described and illustrated. A key to the Libyan genera of the subfamily Akicerinae is provided. Some additional characters of female genitalia at generic and species level are also provided.     

Cephenniini with prothoracic glands and internal cavities: new taxa,enigmatic characters and phylogeny of the Cephennomicrus group of genera (Coleoptera,Staphylinidae, Scydmaeninae)

Genera of the Cephennomicrus group of the Cephenniini (Scydmaenitae) are revised, and the following new taxa are described: Trichokrater gen.n. , Trichokrater ekkentros sp.n. (type species of Trichokrater) (Borneo), Cephennococcus gen.n. , Cephennococcus kuchingensis sp.n. (type species of Cephennococcus) (Borneo), Cephennococcus kenyirensis sp.n. (West Malaysia), Cephennococcus crassus sp.n. (Borneo), Cephennococcus minutissimus sp.n. (West Malaysia), Pomphopsilla gen.n. , Pomphopsilla luhya sp.n. (type species of Pomphopsilla) (Kenya) and Pomphopsilla soror sp.n. (Kenya). Unique subcuticular pockets with setose openings on the pronotum of Trurlia and Trichokrater are identified as glandular structures. Enigmatic internal prothoracic cavities are described for the first time in Scydmaeninae (in Cephennococcus, Pomphopsilla and a female of an undescribed genus from Sulawesi); their fine structure and function remain unknown. Parsimony‐based cladistic analysis of the adult morphology of genera of Cephenniini provided robust evidence for a monophyly of the Cephennomicrus group, composed of Cephennomicrus, Cephennula, Lathomicrus, Pomphopsilla, Cephennococcus, Trurlia, Trichokrater and two undescribed Oriental genera known from females only; this distinct and well‐supported lineage is a sister group of Cephennodes + Hlavaciellus. The genus Cephennomicrus represented in the analysis by species belonging to three previously postulated species groups is not monophyletic, and a comprehensive study comprising more taxa is necessary to reclassify this heterogeneous group.     

Taxonomic position of the cricket genus Eneopteroides Chopard, 1956 (Orthoptera: Grylloidea,Podoscirtidae), with descriptions of two new species

The cricket genus Eneopteroides Chopard, 1956 is transferred from the Eneopteridae to the Podoscirtidae owing to characters in external morphology and male genitalia. One species initially described in the genus Aphonomorphus Rehn, 1903, A. bicolor Hebard, 1928b, is transferred to Eneopteroides and two new species from western Amazonia are described, E. loretensis n. sp. and E. cordobensis n. sp.     

Taxonomic revision of the land snail genera Macrochlamys Gray, 1847 and Sarika Godwin-Austen, 1907 (Eupulmonata: Ariophantidae) from south-eastern Myanmar,with descriptions of three new species

ABSTRACT

Knowledge of Myanmar land snails is based on the late eighteenth to early twentieth century literature and many species need to be re-investigated, especially in the genera Macrochlamys Gray, 1847 and Sarika Godwin-Austen, 1907. In order to update this knowledge, this paper presents information on these two related genera based on new materials from south-eastern Myanmar. Fifteen species are recognised in the south-east of Myanmar. Of these, live material was available for eight Macrochlamys and Sarika species and these are described in full herein, based on data from the shell, external morphology and genitalia, including three species new to science (M. brachystia n. sp., S. concavata n. sp. and S. lopa n. sp.) and five species redescribed (M. aspides, M. kelantanensis, M. petasus, S. consepta and S. obesior). The remaining five species are known only from their shell morphology (M. cauisa, M. perpaula, M. poongee, M. salwinensis and S. birmana) and two species are known from genitalia (S. dugasti and S. resplendens). For these species the shells are figured and some taxonomic remarks are provided.

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     

Maxfischeriinae: a new braconid subfamily (Hymenoptera) with highly specialized egg morphology

The tribe Maxfischeriini, previously placed in Helconinae, is emended to subfamily status based on morphological and biological evidence. Proposed autapomorphies for Maxfischeriinae include: the presence of a pronotal shelf, forewing vein 1a and 2a present, although 1a nebulous, ventral valve of the ovipositor with serrations from tip to base and specialized egg morphology. The novel, pedunculate egg morphology is described for Maxfischeria, representing a new life‐history strategy among Braconidae. Based on egg and ovipositor morphology, we suggest that Maxfischeria is a proovigenic, koinobiont ectoparasitoid. Five new species of Maxfischeria Papp are described with an illustrated key to all species (Maxfischeria ameliae sp.n. , Maxfischeria anic sp.n. , Maxfischeria briggsi sp.n. , Maxfischeria folkertsorum sp.n. and Maxfischeria ovumancora sp.n. ). In addition to the identification key presented here, all known species of Maxfischeria can be separated using the barcoding region of cytochrome c oxidase subunit I (COI). Based on molecular data, the phylogenetic relationships among the six known species of Maxfischeria are as follows: (M. folkertsorum sp.n. (M. ovumancora sp.n. (M. briggsi sp.n. (M. anic sp.n. (M. tricolor + M. ameliae sp.n. ))))).     

Pselaphotumulus,a new genus of pselaphine endemic to New Zealand (Coleoptera: Staphylinidae: Pselaphinae: Pselaphitae)

ABSTRACT

Pselaphotumulus Owens and Carlton, gen. nov., is described as the sixth genus in the tribe Pselaphini known from New Zealand. Three new species are described: Pselaphotumulus aorerei, sp. nov., Pselaphotumulus dubius, sp. nov. and Pselaphotumulus unus, sp. nov.. Three species, Pselaphus cavelli (Broun 1893), Pselaphus oviceps (Broun 1917) and Pselaphus urquharti (Broun 1917) are transferred to Pselaphotumulus, nov. combs. Lectotypes from type series in the New Zealand Broun Collection (Natural History Museum, London) are designated for these three species. Habitus photographs, distributional maps and line drawings of diagnostic characters are provided for each species. A key to species is provided. Searches of museum collections have not yielded representatives outside of New Zealand, suggesting that this is the first endemic genus in the tribe Pselaphini described from the New Zealand’s main islands, specifically, the South Island. Pselaphotumulus species exhibit restricted distribution patterns that approximately coincide with the Pacific/Indo Australian Plate boundary.     

The Phlesirtes complex (Orthoptera,Tettigoniidae, Conocephalinae,Conocephalini) reviewed: integrating morphological,molecular, chromosomal and bioacoustic data

The tettigoniid genus Phlesirtes Bolivar and its allies are reviewed. Morphological, ecological and molecular data prompt the erection of the new genus Chortoscirtes gen.n. with type species Xiphidion meruense Sjöstedt. The genera Phlesirtes, Chortoscirtes, Karniella and Naskreckiella are characterized by morphological characters supported by molecular, acoustic, ecological and chromosomal data. Four species, Chortoscirtes pseudomeruensis sp.n. , C. masaicus sp.n. , C. puguensis sp.n. and C. serengeti sp.n. , are described from localities in northern and coastal Tanzania and one Karniella, K. crassicerca sp.n. , is described from Uganda. The following comb n. are proposed: Phlesirtes kibonotensis (Sjöstedt) and Phlesirtes kilimandjaricus (Sjöstedt). Subtribal status is proposed for the four investigated African genera. A key to the Chortoscirtes species is provided.     

Metallopolia, a new subgenus of Polia (Noctuidae,Noctuinae, Hadenini), with the description of two new species and a new subspecies

A new subgenus of Polia, Metallopolia subgen. n., two new species (Polia (Metallopolia) dysgnorima sp. n. and P. (M.) metagnorima sp. n.) from China (Sichuan, Yunnan, Gansu), and a new subspecies, P. (M.) subviolacea kanchenjunga ssp. n. from Nepal and SE Tibet (Sikkim) are described. Habitus, antennae, male and female genitalia of all Metallopolia species are characterised, depicted and compared with the related species.     

Phylogenetic systematics and evolution of Agnotecous in New Caledonia (Orthoptera: Grylloidea, Eneopteridae)

Abstract. Within a framework for historical analysis of Eneopterinae biogeography the New Caledonian endemic cricket genus Agnotecous Saussure, 1878 is revised: the eight already known species are diagnosed and six new species described, A. azurensis Desutter‐Grandcolas sp.n. , A. chopardi Desutter‐Grandcolas sp.n. , A. clarus Desutter‐Grandcolas sp.n. , A. doensis Desutter‐Grandcolas sp.n. , A. meridionalis Desutter‐Grandcolas sp.n. and A. occidentalis Desutter‐Grandcolas sp.n. Four species groups are characterized by male genitalic structures. Identification keys are provided for both males and females. A cladistic analysis was performed using fifty‐eight morphological characters. The two resultant topologies, which differ only in topology of three apical species, support the monophyly of Agnotecous and that of the four species groups. Preliminary hypotheses of Eneopterinae historical biogeography are derived from phylogenetic and distributional data.     

Revision of the genus Adorodocia Brenske 1893 (Coleoptera: Scarabaeoidea: Rutelinae: Adoretini) endemic to Madagascar

Summary. The Adoretini of the Malagasy endemic genus Adorodocia Brenske 1893 is revised. Fourteen new species and one new subspecies are described and compared with their most closely related species: A. constricta n. sp., A. cuccodoroi n. sp., A. flava n. sp., A. liliae n. sp., A. marginata n. sp., A. peyrierasi n. sp., A. pseudoconstricta n. sp., A. pseudoflava n. sp., A. pseudostrigata n. sp., A. recta n. sp., A. robusta n. sp., A. sogai n. sp., A. vadoni n. sp., A. viettei n. sp. and A. vittaticollis flavipes n. ssp. The synonymy between Adoretus strigatus Waterhouse 1878, and Pseudadorodocia aenigma Arrow 1901, is confirmed. Thus, based on the results of this study, the genus Adorodocia includes 16 species, and one of them is represented by two subspecies. Diagnostic characters to separate the species in the genus deal mostly with the shape of parameres, color of body and legs, shape of pronotum and female eighth tergite, setation of pronotum and elytra. Key to species, diagnoses and distribution for each species are provided. Endophallus and female genitalia are illustrated for the first time for this genus.
