Revisiting the saproxylic beetle ‘Propomacrus cypriacus Alexis & Makris, 2002’ (Coleoptera: Euchiridae) using molecular,morphological and ecological data

Propomacrus cypriacus a saproxylic beetle endemic to Cyprus, was described as a species distinct from P. bimucronatus on the basis of a few morphological characters and has been evaluated as Critically Endangered by IUCN, as it depends on veteran trees and has a restricted distribution. Herein we explored the distribution, ecology, morphology and genetic variation of the populations from Cyprus, and we attempted a phylogenetic analysis including related species based on two mitochondrial and one nuclear DNA markers. We also used published mtDNA divergence rates to date cladogenetic events. Despite extensive sampling, we found only a small number of individuals, adding a few additional localities to the known distribution of the species, and we identified two more host species to those previously reported. Morphological examination showed that only the form of male protibiae differs consistently in Cyprus populations compared to those of P. bimucronatus from Turkey and the Lebanon. Nevertheless, genetic analyses do not support a distinct species status for populations from Cyprus, which should instead be considered as a subspecies of P. bimucronatus. Morphological and ecological data further support this conclusion. Cyprus populations have diverged from nearby continental ones in mid to late Pleistocene.     

A phylogenetic and biogeographic study of Euniphysa (Eunicidae,Polychaeta)

Fourteen species have either been described in, or referred to, the genus Euniphysa. Seven of these are here re-described based on type material and two new species, E. quadridentata and E. filibranchia, are described. Euniphysa oculata is found to be a subjective synonym of E. spinea, and E. unicusa is a subjective synonym of E. aculeata. Euniphysa taiwanensis and E. megalodus are correctly assigned to the genus, but cannot be described due to lack of material. Euniphysa misakiensis, E. tubicola and E. tubifex are transferred to Eunice. A key is given to the nine identifiable species retained in Euniphysa. Coding strategies for polymorphic and inapplicable characters, as well as problems associated with shared absences, are discussed. A phylogenetic analysis of Euniphysa based on 24 morphological characters yielded two most parsimonious trees (CI = 0.902, RI = 0.905). The tree topology separates Euniphysa into two distinct groups. Group I includes E. filibranchia n. sp., E. italica, E. jeffreysii, E. quadridentata n. sp. and E. spinea, it is supported by five equivocal similarities. Group II is supported by five unequivocal synapomorphies and two equivocal similarities, it includes E. aculeata, E. auriculata, E. falciseta and E. tridontesa. Based on the phylogenetic topology, Paraeuniphysa and Heterophysa are considered as junior synonyms of Euniphysa. The recognition of a separate family for Euniphysa is not warranted. All species of Euniphysa are fragile, shallow, warm water species. They have been collected mainly from sandy sediments of the Northern Hemisphere. The greatest diversity is from the South China Sea area; other species are found throughout the Indian Ocean, the Mediterranean Sea and the East Atlantic Ocean coasts suggesting the genus may have originated in the Tethys Sea. A few species have also been found in the Gulf of Mexico and the West Atlantic Ocean coast again suggesting a Tethyan origin associated with the westward drift of the North American continent.     

The sentinel crabs of the genus Chaenostoma (Stimpson, 1858) (Crustacea: Brachyura: Macrophthalmidae), with description of a new species and new records

The genus Chaenostoma (Stimpson, 1858) so far includes four distinct species, i.e. C. boscii (Audouin, 1826), C. lisae (Poupin and Bouchard, 2010), C. punctulatus Miers, 1884, and C. sinuspersici (Naderloo and Türkay, 2011). Chaenostoma java n. sp. is here described as a fifth species from Java (Indonesia) easily distinguished from its congeners by the features of the male first pleopod, the penultimate segment of the male abdomen, and the unique female gonopore. The new species is most similar to C. lisae, but they differ in the morphology of the male chelipeds and female gonopores. Chaenostoma lisae is redescribed and recorded from Madagascar, Mayotte I. and New Caledonia. An identification key for the genus is provided.     

The jumping plant-lice (Hemiptera,Psylloidea) associated with Schinus (Anacardiaceae): systematics,biogeography and host plant relationships

The gall-forming psylloid fauna associated with the temperate Neotropical plant genus Schinus (Anacardiaceae) is revised, and keys are provided for adults, larvae and galls. Fourteen species are recognized in the genus Calophya (Calophyidae), 10 of which are described as new; C. gallifex and C. schini are reinstated from former synonymy with C. rubra. An additional closely related new species, C. clavuligera sp. n., is described from Lithrea spp. In the genus Tainarys (Psyllidae, Rhinocolinae), six species are recognized and, for five of these, Schinus species are confirmed hosts. Two of them are described as new and one is recombined from Leurolophus. A new Leurolophus species is described from Lithrea molleoides. Based on a cladistic analysis Pelmatobrachia, Microceropsylla and Neocalophya are synonymized with Calophya, producing five new and one revised species combinations as well as one nomen nov. A list of the 59 currently recognized species is provided with information on synonymy, distribution and host plants. The cladistic analyses suggest that the Schinus inhabiting calophyids form two monophyletic groups, the C. rubra and C. hermicitae groups, respectively. A discriminant analysis of 15 variables for both males and females provides morphometric characters for separating the morphologically very homogenous adults of the C. rubra group. The phylogenetic relationships of the Rhinocolinae are re-evaluated, and the genera Tainarys and Leurolophus are redefined. Notophyllura is transferred from the Euphyllurinae to the Rhinocolinae. Tainarys forms the sister group of Leurolophus + Notophyllura. Based on mapped distributions four areas of endemism (distribution) are defined: A (Eastern temperate South America), B (Central and Southern Chile, including adjacent parts of Argentina), C (Central Argentina) and D (Peru, Far Northern Chile, and Eastern Bolivia). Cladistic biogeographical analyses with TAS, COMPONENT and an algorithm by Enghoff yielded the general area cladogram (A +(C +(B +D))); the one calculated with BPA differed in the position of D: (D +(A +(B +C))). The reconstruction of vicariant events using a protocol by Hovenkamp, corroborates the former general area cladogram, which is compared to competing hypotheses. The history of dispersal and vicariance events is reconstructed with the programme DIVA. Evidence for cospeciation of Schinus with its associated psylloids is evaluated with COMPONENT and TREE MAP. The likelihood for cospeciation is high in the Calophya hermicitae group, but low in the Calophya rubra group and in Tainarys. The gall shape depends partly from the psylloid, partly from the Schinus phylogeny.     

A revision of the genus Platythelphusa A. Milne-Edwards, 1887 from Lake Tanganyika,East Africa (Decapoda: Potamoidea: Platythelphusidae)

The genus Platythelphusa is revised and six species are recognized. These species are P. armata A. Milne-Edwards, 1887, P. maculata (Cunnington, 1899), P. conculata Cunnington, 1907, P. tuberculata Capart, 1952, P. polita Capart, 1952 and P. echinata Capart, 1952. A seventh taxon, P. denticulata Capart, 1952 is considered here to be a junior synonym of P. conculata. A diagnosis for each species is provided and most are figured from the type. Keys to the families of African freshwater crabs and to the genus Platythelphusa are also provided.     

New species of the cicada genus Semia Matsumura (Hemiptera: Cicadidae) from China and a phylogeny of Semia spp. and their relatives based on molecular data

Two new cicada species, Semia brevidilata, sp. nov. and Semia tibetensis, sp. nov., are described from China. Semia majuscula, a newly recorded species to China, is re-described, as some new characteristics are recognised which may be useful for further taxonomic and phylogenetic analysis of this genus and its allies. Partial mitochondrial cytochrome oxidase subunit I (COI) sequences of five Semia species and relatives belonging to the genera Pomponia Stål and Psithyristria Stål are further analysed to confirm the validity of related new species and to provide a useful reference for the identification of Semia. A key to all species of Semia is provided, and the phylogenetic relationships among species of Semia and their relatives are discussed.

Recent and fossil Lunulitidae (Bryozoa: Cheilostomata) 4. American and Australian species of Otionella

The nominal, free living lunulitiform genus Otionella has been found to include two major groups of species, each one with a distinctive periancestrular pattern of primary zooids. The first group occurs in the Eocene of North America and includes the type species, O. perforata, and several other forms. The second group occurs in the Late Eocene to Recent of Australasia, and may prove to be generically distinct. Intermediate forms, such as O. parvula from the Argentinian Tertiary, are discussed, and a diverse fauna of 10 species from Australia is described. Although some of these species, like O. cupola, O. exigua and O. nitida, have long been known from Australia. it has only recently been recognized that three New Zealand forms, O. squamosa, O. zelandica and O. proberti, also occur in the Tertiary and/or Recent of Victoria, New South Wales, and Western Australia. In addition, four species are considered to be new. These include O. australis, O. auricula and O. minuta, which are probably closely related to one another, and to O. zelandica. The fourth species, O. browni, has a unique periancestrular budding pattern which resembles that of fossil Lunulites more than any form of ‘Australasian Otionella’. Although, in many ways, O. browni could be assigned to Lunulites sensu lato, it is included here in Otionella.     

A revision of Astyanax (Characiformes: Characidae) in Central and North America,with the description of nine new species

Since the restriction of Astyanax fasciatus to Brazil, most authors have assigned Central American and southern Mexican forms of Astyanax to A. aeneus. However, molecular studies support the hypothesis that more than one taxon is involved. With the aim of clarifying the number and status of species hidden behind the name ‘A. aeneus’, this revision comprises 80 populations of Astyanax (and ‘Bramocharax’) from Panama to Texas, with comparative material from South America, based on morphological characters (mostly osteological). Astyanax aeneus is hereby restricted to the Pacific slope, from Río Papagayo, Guerrero, to Honduras. Several species are resurrected from synonymy or redescribed: A. altior (restricted to north-western Yucatán), A. argentatus (Texas and northern Mexico), A. belizianus (central-southern Belize, Izabal, Caribbean Honduras), A. brevimanus (upper Usumacinta and Grijalva, Chiapas, Quiché, Alta Verapaz), A. finitimus (Veracruz, Tabasco, northern Chiapas), A. mexicanus (restricted to Colima and the Balsas River basin), A. nicaraguensis (Caribbean Nicaragua to Sixaola, Panama), A. orstedii (south-eastern Nicaragua, Costa Rica and westernmost Panama), A. panamensis (Pacific Panama), and A. petenensis (Campeche, Petén). Nine species are newly described: A. acatlanensis sp. nov. (inland Oaxaca and Puebla), A. bacalarensis sp. nov. (Quintana Roo, northern Belize, Petén), A. cubilhuitz sp. nov. (Alta Verapaz), A. macal sp. nov. (Maya Mountains, Belize), A. ocotal sp. nov. (Lake Ocotal, highland Chiapas), A. rioverde sp. nov. (San Luis Potosí), A. salvatoris sp. nov. (Tamazulapan, Oaxaca), A. tamiahua sp. nov. (northern Veracruz) and A. tehuacanensis sp. nov. (Papaloapan, Oaxaca). Others were already recognised as different from A. aeneus, among these A. cocibolca and A. nasutus, as well as species included before in the genus Bramocharax.

Palaearctic species of Ammoplanus (Hymenoptera: Sphecidae)

The Palaearctic species of the genus Ammoplanus Giraud are revised, based on material of over 1750 specimens from Europe, North Africa and Central Asia. For almost all species it was possible to examine the type material and in six species the lectotypes have been designated, in two cases (A. perrisi and A. marathroicus) the neotypes. As a result 38 species are recognized as valid, keyed out and commented on. Eight species are described as new and four species names are here placed in synonymy. Several species are of wide distribution, which made it necessary to include also those described from Central Asia and Mongolia. The keys are made to all Palaearctic species but no material is known from the regions east of Mongolia, although four undescribed species are available from South-East Asia. The Afrotropical species are listed and most of them were also examined. Two subgenera are recognized in the region; 32 species are classified in Ammoplanus sensu stricto and six in the subgenus Ammoplanellus. In the nominal subgenus the following species are described as new: A. atlasensis from Morocco, A. biscopula from Israel, A. biskrensis from Algeria, A. denesi from Turkey (Anatolia), A. freidbergi and A. kaplanae from Israel, A. minutus from Bulgaria and Turkey and A. strumae from Bulgaria and Greece. New synonymy: A. angelae becomes a junior synonym of rhodesianus (known before only from Africa), A. crudelis a synonym of A. kaszabi, A. handlirschi a synonym of A. marathroicus, A. suarezi a synonym of A. kohlii, A. subcompressus of A. gegen, A. orbiculatus of A. simplex and A. zarcoi of A. kohlii; A. wesmaeli is confirmed as a synonym of A. perrisi. Otherwise the synonymy is corrected under A. bischoffi and the names A. dusmeti and A. curvidens are re-established as valid. In a short review of the African species A. (Ammoplanellus) cradockensis Arnold, 1959 is placed as a new synonym under A. (Ammoplanellus) latiscapus Leclercq, 1959. The nomenclatural changes are explained under the relevant species.     

A review of the north-western Pacific species of the genus Paguristes (Decapoda: Anomura: Diogenidae), I. Five species initially reported by Ortmann (1892) from Japan

Five species of the hermit crab genus Paguristes Dana, 1851, initially reported by Ortmann (1892) from Japan, are revised based on the materials reported by Ortmann (1892), Doflein (1902), Balss (1913) and Miyake (1978), and on newly collected specimens. The specific status of P. palythophilus Ortmann, 1892, is clarified, and a species confused with P. palythophilus is described as new, P. albimaculatus. It has been revealed that P. kagoshimensis Ortmann, 1892, is actually a junior subjective synonym of P. digitalis Stimpson, 1858. The species heretofore assigned to P. kagoshimensis is described as new, P. versus. It has been confirmed that Paguristes acanthomerus Ortmann, 1892, is a valid species and that P. barbatus sensu Ortmann, 1892, is the same species as P. ortmanni Miyake, 1978. Further, a new species, P. doederleini, is described for P. setosus sensu Ortmann, 1892. It is also shown that a part of the group of specimens identified as Paguristes puniceus by Miyake (1978) is referable to P. doederleini. In addition to the three new species recognized herein, the four previously described species are also redescribed in detail in order to make clear their taxonomic status.     

A review of the South-East Asian Nasutitermitinae (Isoptera: Termidae), with descriptions of one new genus and a new species and including a key to the genera

This paper describes Snootitermes leuserensis, gen. et sp. nov. (collected from the Leuser Ecosystem, Sumatra), Hirtitermes brabazoni sp. nov. (collected from north Sulawesi) and the major soldier of Ceylonitermes indicola. It also includes a revised generic key to the Nasutitermitinae of Peninsular Malaysia, Java, Sumatra and Borneo and reassigns the South-East Asian Subulitermes-group of termites to the Nasutitermes-group. Aciculioiditermes denticulatus and A. sarawakensis are considered to be junior synonyms of Aciculioiditermes holmgreni. The genera Aciculioiditermes and Proaciculitermes are considered to be junior synonyms of Malaysiotermes. Therefore Aciculioiditermes holmgreni, Proaciculitermes orientalis, P. sabahensis, P. malayanus and P. lowi are all Malaysiotermes species. Tho's (1982, 1992) unpublished new genus (Genus A) is considered to be a new species of Ceylonitermes. Oriensubulitermes borneensis is shown to be a Subulioiditermes species, S. borneensis. Nasutitermes matangensiformis is shown to be a junior synonym of N. matangensis. Havilanditermes is shown to be a junior synonym of Nasutitermes.     

Cryptic and non-cryptic diversity in New Guinea ground snakes of the genus Stegonotus Duméril,Bibron and Duméril, 1854: a description of four new species (Squamata: Colubridae)

ABSTRACT

The island of New Guinea has been identified as biologically megadiverse but many taxa are still poorly known. This is especially the case for many of the island’s snakes, which by their very nature can be difficult to collect and study. Here we examine the phylogenetic and phylogeographic structure of a poorly studied snake genus, Stegonotus, focusing on the species of New Guinea; until now, Stegonotus has never been examined using modern phylogenetic methods. Using molecular data from 49 individuals representing eight of the ten described species, and including all New Guinea taxa, we estimate a multilocus phylogeny and examine population structure to help identify undescribed taxa. We use morphological data from the corresponding museum vouchered specimens (where available) and also examine additional specimens for taxa not included in the molecular data set to determine morphological differences among putative taxa. We find molecular evidence for four new species of Stegonotus, both morphologically obvious and cryptic, and describe them herein. The recognition of these four species indicates that Stegonotus diversity has been previously underestimated and also suggests that there are likely additional undescribed taxa within the genus. These four taxa increase the number of described species by 40% and further confirm New Guinea as the centre of diversity for the genus.

New species of cheilostomatous Bryozoa from subantarctic Marion and Prince Edward Islands

Fifteen new species of cheilostomatous Bryozoa are described from the subantarctic Marion and Prince Edward Islands: Pyriporoides judyae, Valdemunitella dianae, Cornucopina elongata, Cornucopina bryonyae, Cornucopina antlera, Paracellaria elizabethae, Filaguria lithocrustata, Celleporella marionensis, Catenicella glabrosa, Ipsibuffonella hyalina, Parkermavella corrugata, Calloporina spinosa, Fenestrulina pumicosa, Microporella mandibulata, and Reteporellina berylae. Two species originally described from the region, Sclerodomus myriozoides and Reteporella gigantea, are here reported for only the second time, while three others, Celleporella alia, Celleporella bougainvillei, and Talivittaticella frigida, represent new records for Marion Island. Phonicosia jousseaumei was previously recorded from Marion Island as P. circinata.     

Revision of Aleiodes (Hemigyroneuron) parasitic wasps (Hymenoptera: Braconidae: Rogadinae) with reappraisal of subgeneric limits,descriptions of new species and phylogenetic analysis

The parasitic rogadine braconid wasp subgenus Hemigyroneuron, previously and inappropriately synonymized with Aleiodes (Chelonorhogas) as a result of misidentification, is here synonymized with Aleiodes (Pholichora). A key to the 26 species of Aleiodes (Hemigyroneuron) is presented, including 16 which are described and illustrated as new: A. (H.) amoretae Butcher and Quicke, A. (H.) faddenae Butcher and Quicke, A. (H.) glandularis Butcher and Quicke and A. (H.) plurivena Butcher and Quicke from South Africa; A. (H.) bakeri Butcher and Quicke from Indonesia; A. (H.) bengalensis Butcher and Quicke from India; A. (H.) cusackae Butcher and Quicke from Uganda; A. (H.) elgon Butcher and Quicke, A. (H.) meruensis Butcher and Quicke and A. (H.) pappi Butcher and Quicke from Kenya; A. (H.) fenwickae Butcher and Quicke from Congo; A. (H.) pseudospeciosus Butcher and Quicke from Brunei; A. (H.) roberti Butcher and Quicke from Thailand; A. (H.) sharkeyi Butcher and Quicke from Madagascar; A. (H.) trianguliscleroma Butcher and Quicke from Malawi and Kenya; and A. (H.) ugandaensis Butcher and Quicke from Uganda. A. (H.) apicale (Brues) comb. nov., A. (H.) dubiosus (Fullaway) comb. nov., A. (H.) speciosus (Baker) comb. nov. and A. (H.) suffusus (Baker) comb. nov. are redescribed and illustrated. Males of most species of A. (Hemigyroneuron) are shown to possess a glandular pore opening near the mid-posterior margins of metasomal tergites 4–6, though the situation in A. (H.) dubiosus is different. Results of morphological phylogenetic analysis are presented and indicate clear separation between African and Asian species groups. Two of the new species have been reared from Geometridae and one apparently from Pieridae.     

Taxonomy,phylogeny and distribution of the longicorn beetle genus Allotisis Pascoe (Coleoptera: Cerambycidae: Phoracanthini)

The genus Allotisis Pascoe is revised. Diagnosis of Allotisis is given, three known species are redescribed and six species are described as new : A. repleta, A. notabilis, A. rara, A. labyrinthina, A. monteithi and A. furva. All species are from Australia. Thoris moerens Blackburn is synonymous with A. unifasciata. A key to the nine species is provided. Phylogenetic analysis suggests that this genus be divided into two species groups, monteithi-group and unifasciata-group. Several subgroups are also identified. Biogeographic distribution of these species groups and subgroups is discussed.
