Review of the leafhopper tribe Scaphytopiini (Homoptera: Cicadellidae: Deltocephalinae) with a key to genera

The leafhopper tribe Scaphytopiini is reviewed, and a key to genera given. The following taxonomic changes are made: Masiripius lugubris (Distant) comb. nov. (from Mahalana); Mahalana Distant, junior synonym of Platymetopius Burmeister syn. nov. (Athysanini); Hododoecus bunyensis Evans comb. nov. (from Stenometopius) (Stenometopiini). In addition, the monotypic genus Nesothamnus Linnavuori is transferred from Athysanini to Scaphytopiini and its characters discussed.     

Rediscovery of Disepyris semiruber (Kieffer) (Hymenoptera: Bethylidae) in Southern Africa,with first description of the male

Holepyris semiruber Kieffer is redescribed and illustrated based on freshly collected specimens. Holepyris semiruber var. striatipleura Kieffer is considered a colour variant of this species and therefore a junior synonym of H. semiruber syn. nov. This species is transferred to Disepyris, D. semiruber (Kieffer) comb. nov., based on the possession of a short 2r-rs&Rs vein in the fore wing and presence of long flat spine-shaped setae on the outer (posterior) surface of the protarsi. The male is described for the first time from new specimens collected in South Africa. This species is recorded for the first time from Namibia and Zimbabwe. All photographs are available on www.waspweb.org.     

Reclassification of Bracon mendocinus,a gall‐associated doryctine wasp,and description of a new closely related species of Allorhogas (Hymenoptera: Braconidae)

One of the first reported gall‐associated braconids, from 1910, Bracon mendocinus Kieffer and Jörgensen, is removed from the subfamily Braconinae and transferred to the doryctine genus Allorhogas, A. mendocinus (Kieffer and Jörgensen) comb. nov. A new species morphologically similar to A. mendocinus, A. joergenseni Martinez and Zaldivar‐Riverón sp. nov., is also described. Additionally a neotype is designated for B. mendocinus Kieffer and Jörgensen. We base our conclusions on the morphological examination of recently collected specimens from central Argentina associated with galls on Lycium chilense (Solanaceae), as well as on the DNA variation at 28S ribosomal RNA and cytochrome oxidase subunit I (COI) mitochondrial DNA genes.     

Studies on gorgoderid digeneans from Australian and Assian Freshwater fishes

Pseudophyllodistomum gen. nov. is proposed for a section of Phyllodistomum Braun, 1899. The new genus is distinguished by the simple form of the uterus, the eggs which reach over 60 μm long in length, the saccular excretory bladder, the 2[3 + 3 + 3) + (3 + 3 + 3)] = 36 flame-cell formula, the metacercaria which may have fully developed genitalia and is parasitic in decapod crustaceans, the use of corbiculid bivalves as first intermediate hosts, and the cercaria which has a long tail not enclosing the cercarial body. Two species, P. johnstoni sp. nov. and P. murrayense sp. nov., are described from Australian freshwater fish and five new combinations of previously described Phyllodistomum species from Asian freshwater fish are proposed — P. macrobrachicola (Yamaguti, 1934) comb. nov., P. lesteri (Wu, 1938) comb. nov., P. srivastavai (Rai, 1964) comb. nov., P. lucknowense (Pandey, 1970) comb. nov. and P. mingense (Tang, 1985) comb. nov. The first intermediate host of P. johnstoni is a Corbiculina species. The long-tailed cercariae infect the gonads of palaemonid prawns, Macrobrachium spp., in which they grow to unencysted metacercariae which may have fully developed genitalia. The metacercaria of P. murrayense also infects a Macrobrachium species. The evolution of the Gorgoderinae is discussed and it is suggested that, prior to the erection of Pseudophyllodistomum, Phyllodistomum may have encompassed as many as five different phylogenetic lines, each with similar adult morphology but distinguishable by life-cycle characters. It is postulated that more study will lead to further division of Phyllodistomum.     

CVIII.—The African spiders of the family Ctenidae in the collections of the British Museum (Natural History)

Summary

The African Ctenidae in the Collections of the British Museum (Natural History) are revised. Thirty species are contained in the subfamilies Cteninae and Acantheinae. Ctenus batesii Pocock, 1903, is a synonym of Ctenus capulinus (Karsch), 1879, Ctenus dirus Thorell, 1899, is a synonym of Ctenus kingsleyi F. O. P.-Cambridge, 1898, Ctenus marshalli F. O. P.-Cambridge, 1898, is a synonym of Ctenus melanogastra (Bösenberg & Lenz), 1895, and Ctenus spenceri F. O. P.-Cambridge, 1898, is a synonym of Ctenus pulchriventris Simon, 1896.

The subfamily Acantheinae is recorded from Africa for the first time. A new genus, Africactenus, is erected for a group of allied species. The genotype is Ctenus agilior Pocock, 1899, and the following new species are described:—A. depressus, A. desartsi, A kribiensis, A. pococki, A. sandersoni, A. simoni, A. sladeni, A. tridentatus and A. trilateralis. Ctenus longurio Simon, 1909, is transferred to the genus Africactenus on examination of the type-material.

Certain species from the Simon Collection are listed in the Appendix and figured for the first time.     

The Philippine Coroebini (Coleoptera: Buprestidae: Agrilinae)

The known Philippine genera of Coroebini are briefly discussed and separated in an illustrated key. Vanroonia marmorea (Deyrolle), comb. nov., is transferred from Amorphosoma Laporte. Sibuyanella Obenberger is synonymized under Obenbergerula Strand, resulting in Obenbergerula bakeri (Fisher), comb. nov. Anocisseis samarensis, gen, et spec. nov., is described from Samar Island, Philippines. A Bornean species, Coroebus rajah Fisher, is transferred to Anocisseis.     

Revision of the sesarmid crab genera Labuanium Serène and Soh, 1970, Scandarma Schubart,Liu and Cuesta, 2003 and Namlacium Serène and Soh, 1970 (Crustacea: Decapoda: Brachyura: Sesarmidae), with descriptions of four new genera and two new species

ABSTRACT

The systematics of the arboreal sesarmid crab genera Labuanium Serène and Soh, 1970 and Scandarma Schubart, Liu and Cuesta, 2003 is revised. Also included is the poorly known genus Namlacium Serène and Soh, 1970, which is morphologically similar to Labuanium and may also be arboreal in habit. The present study restricts Labuanium to its type species, L. politum (De Man, 1887), and congeners are transferred to Scandarma, Geosesarma De Man, 1892, and three new genera established herein: Circulium gen. nov., Shinobium gen. nov. and Mindanium gen. nov. Two new species of Scandarma are described from Papua New Guinea and Madagascar. Sesarma jacquinoti Ortmann, 1894, previously regarded as a synonym of Scandarma gracilipes (H. Milne Edwards, 1853) (comb. nov.), is here shown to be a junior synonym of Sesarmops angustifrons (A. Milne-Edwards, 1869). Labuanium schuetteii (Hess, 1865) is regarded as conspecific with Scandarma gracilipes (H. Milne Edwards, 1853) (comb. nov.) and the lectotype of the latter species (here designated) is also selected as the neotype of the former, making the two names objective synonyms. Material which had been identified as ‘Labuanium finni Alcock, 1900’ by Pretzmann (1984) from the South Andaman Islands is actually the poorly known Geosesarma thelxinoe (De Man, 1908), which is here referred to a new genus, Andamanium gen. nov. Sesarma finni Alcock, 1900 s.s. is herein assigned to Scandarma. Namlacium crepidatum (Calman, 1925), the only species in the genus, is redescribed and figured and compared with Labuanium and Scandarma. Keys to species of Circulium and Scandarma are provided.

Macrobrachium malayanum (Roux, 1934) stat. nov. (Decapoda,Palaemonidae) as a synonym of M. geron Holthuis, 1950, with notes on its distribution

Macrobrachium pilimanus malayanus (Roux, 1934) is synonymized with M. geron Holthuis, 1950 and accorded full species status as M. Malayanum (Roux, 1934) stat. nov. A lectotype is also designated. Variation within M. malayanum and differences between this species and M. pilimanus (De Man, 1879) are discussed, and the taxonomy of the species clarified. New records of M. malayanum are presented for Sarawak and Sumatra.     

Two new genera of Epilachnini Mulsant from New Guinea and Aru Islands (Coleoptera: Coccinellidae)

The species formerly classified in the genus Afidentula Kapur from New Guinea and Aru Islands are revised. As a result of detailed analysis of mouth parts and genital structures of the species, two new genera are proposed: monotypic Lalokia gen. nov. from Aru Islands and New Guinea, with Lalokia aruensis (Crotch) (comb. nov.), and Papuaepilachna gen. nov. from New Guinea including Papuaepilachna bivacana (Bielawski) (comb. nov.), P. kapuri (Bielawski) (comb. nov.), P. nasti (Bielawski) (comb. nov.), P. tenmana (Bielawski) (comb. nov.), P. watalai (Jadwiszczak) (comb. nov.) and P. wiebesi (Bielawski) (comb. nov.). All species are illustrated and an identification key to the species of Papuaepilachna is provided. A key to the genera of Epilachnini from New Guinea and Aru Islands is also provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:F721B07F-CBF0-4516-853D-1FD434FE06F1     

The Andean tarantulas Euathlus Ausserer, 1875, Paraphysa Simon, 1892 and Phrixotrichus Simon, 1889 (Araneae: Theraphosidae): phylogenetic analysis,genera redefinition and new species descriptions

Based on a phylogenetic analysis we revised the Chilean tarantula genera Euathlus and Paraphysa. As results of our analyses, within a wider context of South American lineages, Paraphysa is synonymous of Euathlus, and Phrixotrichus is resurrected. Euathlus and Phrixotrichus are sister genera, supported by their shared palpal organ morphology, especially at the ventral position of the distal prolateral inferior keel, also by spermathecal receptacles with a lateral chamber, and tarsal claws without teeth. Both genera are redefined based on cladistic results, and some of their constituent species are transferred. We describe four new species, and for the first time present the spermathecae of Euathlus parvulus comb. nov. All species described for both genera are diagnosed and keyed. Euathlus now includes: Euathlus antai Perafán and Pérez-Miles sp. nov., Euathlus atacama Perafán and Pérez-Miles sp. nov., Euathlus condorito Perafán and Pérez-Miles sp. nov., Euathlus manicata (Simon 1892) comb. nov., Euathlus parvulus (Pocock, 1903) comb. nov. and Euathlus truculentus L. Koch, 1875. Phrixotrichus now comprises: Phrixotrichus jara Perafán and Pérez-Miles sp. nov., Phrixotrichus scrofa (Molina, 1788) comb. nov. and Phrixotrichus vulpinus (Karsch, 1880) comb. nov. Furthermore, Paraphysa riparia Schmidt and Bolle, 2008 is synonymized with Eupalaestrus weijenberghi (Thorell, 1894), Paraphysa pulcherrimaklaasi Schmidt, 1991 is transferred to Maraca Pérez-Miles, 2006 and Paraphysa peruviana Schmidt, 2007 is considered a nomen dubium.

Description of two new species of Guernea (Crustacea,Amphipoda, Dexaminidae) from Japan,with tentative revision of subfamily Prophliantinae

Guernea minor sp. nov. and G. ezoensis sp. nov. are described from Japan. Based on these new species and the literature, a tentative revision of the subfamily Prophliantinae is proposed. The subgenus Prinassus of the genus Guernea is invalidated. The subgenus Haustoriopsis of the genus Guernea is re-elevated to a separate genus from Guernea. Dexaminoculus is transferred from Prophliantinae to Dexamininae.     

Some monogenean parasites of marine perciform fishes of Kuwait

Three monogenean parasites are reported from marine perciform fishes kept in culture tanks at Al-Raas, Kuwait. Tareenia acanthopagri gen. et sp. nov. (Capsalidae: Benedeniinae) and Polylabris angifer sp. nov. (Microcotylidae: Prostatomicrocotylinae) are described from skin and gills, respectively, of Acanthopagrus latus (Sparidae). Megalocotyloides epinepheli Bychowsky and Nagibina, 1967 (Capsalidae: Megalocotylinae) is recorded from skin of Epinephelus tauvina (Serranidae). It is also proposed that Benedenia plataxicola Gupta and Khanna, 1975 and Allometabenedeniella plataxi Velasquez, 1982 are synonyms of Benedenia orbicularis Gupta and Khanna, 1975 and that the latter is transferred to the genus Allometabenedeniella Velasquez, 1982 as A. orbicularis comb. nov. Allosprostonia tauvinae Lawler and Hargis, 1968 is considered to be a synonym of Megalocotyloides epinepheli Bychowsky and Nagibina, 1967.     

Taxonomic revision of the fruit fly genus Perilampsis Bezzi (Diptera,Tephritidae)

The Afrotropical fruit fly genus Perilampsis Austen is revised. In total, 17 species are recognized of which three are new to science: P. deemingi sp. nov., P. incohata sp. nov., and P. rubella sp. nov. Perilampsis thyene Munro is considered a junior synonym of P. amazuluana Munro. All species are described or re-described, with illustrations of wing patterns and female terminalia where deemed necessary for unambiguous identification. Their host-specificity is briefly discussed. An identification key to species is provided.     

The parasitic wasp genera Skiapus,Hellwigia, Nonnus,Chriodes, and Klutiana (Hymenoptera,Ichneumonidae): Recognition of the Nesomesochorinae stat. rev. and Nonninae stat. nov. and transfer of Skiapus and Hellwigia to the Ophioninae

The ichneumonid wasp genera Skiapus Morley, Hellwigia Gravenhorst, Nonnus Cresson, Chriodes Förster, and Klutiana Betrem are each formally removed from the Campopleginae on the basis of morphological, molecular, and simultaneous analyses using PAUP* and the optimization alignment program POY. Skiapus and Hellwigia are shown to form a monophyletic group with the Ophioninae to which they are transferred. Nonnus is treated as comprising the Nonninae stat. nov. and Chriodes and Klutiana (sometimes treated as a junior synonym of Chriodes) are treated as comprising the Nesomesochorinae stat. rev. The status of Nesomesochorinae and Nonninae is not fully resolved as they are not consistently recovered as separate groups, forming a single clade in some analyses. We keep them separate because of this uncertainty. Molecular synapomorphies within the D2–3 expansion region of the 28S rDNA gene show the utility of this gene region in determining subfamily‐level placement within the higher Ophioniformes.     

Revision of the genus Lepidastheniella Monro, 1924 (Polychaeta: Polynoidae: Lepidastheniinae) with notes on the subfamily Lepidastheniinae and the description of a new species

The present revision covers all known species of the genus Lepidastheniella Monro, 1924 (i.e. Lepidastheniella comma (Thomson, 1902), L. phillippensis Monro, 1924 and L. monroi Benham, 1950). The comparison of the available type material showed that L. monroi is a junior synonym of L. comma and that specimens from a collection of scale worms from off Shimoda (Japan) belong to the new species L. nishii sp. nov. described herein. The generic diagnosis of Lepidastheniella is emended and an identification key to all valid species given. Additionally, the subfamily affiliation of Lepidastheniella is discussed, distinctive characters of all genera belonging to the subfamily Lepidastheniinae Pettibone, 1989 are described, and an identification key to these genera is given.     

A revision of the subtribe Hippomelanina,part II: Gyascutus (Gyascutus) LeConte (Coleoptera: Buprestidae)

The subgenus Gyascutus (Gyascutus) is revised and 12 species are recognized: G. planicosta (LeConte) with three subspecies— G. p. planicosta (LeConte), stat. nov.; G. p. obliteratus (LeConte), stat. nov., with G. pistorius Casey as a syn. nov.; and G. p. cribriceps Casey, stat. nov.; with syn. nov. as follows: G. acutangulus Casey, G. amplus Casey, G. amplus aerata Casey, G. egregius Casey, and Hippomelas (G.) lariversi Barr; G. insularis (Helfer), comb. nov.; G. castaneus (Helfer), comb. nov.; G. fulgidus (Barr), comb. nov.; G. pacificus (Chamberlin), comb. nov.; G. paragranulatus Nelson, sp. nov.; G. granulatus (Van Dyke), comb. nov.; G. westcotti Nelson, sp. nov.; G. carolinensis Horn with syn. nov. as follows: G. juniperinus Wickham, G. obesus Casey, G. obesus aeneoviridis Casey, G. compactus Casey, G. compactus solidus Casey, G. cylindrinus Casey, G. debilis Casey, and G. tenuis Casey; G. dianae (Helfer), comb. nov.; G. allenrolfeae (Verity), comb. nov.; and G. jeanae (Nelson), comb. nov. All species and subspecies are described and information on type localities, variation, distribution, biology, and comparisons is presented. Keys to the species and subspecies are provided. Photographs of each species and drawings of body parts, including male genitalia, are included.     

LXVI.—The non-marine mollusca of Sierra Leone

Summary

The families Opecoelidae, Lepocreadiidae and Enenteridae are differentiated. The Enenteridae is considered to consist of three subfamilies, the Enenterinae, the Cadenatellinae subfam. nov. and the Pseudolepidapedinae, whose constituent genera are listed. The diagnostic features of the opecoelid subfamilies Opecoelinae, Plagioporinae and Stenakrinae are presented. Plagioporus is restricted to freshwater forms, and Lebouria is considered a synonym of Peracreadium, following the transfer of L. idonea Nicoll, 1909, to the latter genus as P. idoneum comb. nov. Caudotestis is considered to belong to the Stenakrinae, Trematichtys to the Allocreadiidae, Spinoplagioporus to the Enenterinae and Pycnadenoides to the Plagioporinae. Macvicaria gen. nov., with the type-species M. [Plagioporus] alacris (Looss, 1901) and also containing M. [Distoma] soleae (Dujardin, 1845) (syn. Plagioporus varius) is erected for some of the marine forms previously allocated to Plagioporus. Neolebouria is briefly discussed and N. merretti sp. nov. from Bathytyphlops sewelli is described. Gaevskajatrema gen. nov. is erected for type-species G. [Peracreadium] perezi (Mathias, 1926) and G. [Plagioporus] lethrini (Nagaty, 1942). Podocotyle is discussed, especially in relation to P. angulata (Dujardin, 1845), which is reinstated as the type-species, P. atomon (Rud., 1802) and P. staffordi Miller, 1941, and P. abitionis McFarlane, 1936, is transferred to Pellamyzon. Tellervotrema gen. nov. is erected for the type-species T. armstrongi sp. nov. from Nezumia aequalis, which is described, and T. [Plagioporus] beringi (Mamaev, 1965). The genera Peracreadium, Cainocreadium, Hamacreadium, Bathycreadium and Helicometra are also briefly discussed. In addition, a key to the plagioporine genera occurring in European Atlantic waters is presented.     

Stalked crinoids from Tasmanian seamounts. Part 1: Hyocrinidae

Faunal investigations conducted in 1997 on southern Tasmania seamounts, produced 10 specimens of stalked crinoids belonging to the family Hyocrinidae. These are the first hyocrinids to be recorded from this area. Three new species are described: Feracrinus koslowi sp. nov., Ptilocrinus tasmaniaensis sp. nov. and Ptilocrinus australis sp. nov. New data show that three previously described species should be referred to a single species Feracrinus aculeatus Mironov and Sorokina, 1998 and the genus Camaecrinus Mironov and Sorokina, 1998 becomes a junior synonym of Feracrinus. Although they have close affinities, the two species belonging to the genus Feracrinus live in different areas of the western Pacific. Ptilocrinus tasmaniaensis sp. nov. and P. australis sp nov. are the shallowest known species in the genus Ptilocrinus (sensu stricto). There is no evidence of endemism in hyocrinids living on south Tasmania seamounts.     

Some helminth parasites of marine fishes of South Africa: Families Gorgoderidae,Zoogonidae, Cephaloporidae,Acanthocolpidae and Lepocreadiidae (Digenea)

The following digeneans are described, recorded or figured from South African waters: Phyllodistomum tongaatense sp. nov. from Coracinus multifasciatus; Steganodermatoides [= Proctophantastes] allocytti comb. nov.

The Cassidininae Hansen, 1905 (Crustacea: Isopoda: Sphaeromatidae) of Australia

The Cassidininae of Australia are revised. The status of the subfamily is assessed and it is concluded that, as presently constituted, the Cassidininae is an artificial taxon. It is maintained here as a taxon of convenience (sensu lato) until the other sphaeromatid subfamilies can be reassessed, but a new diagnosis (sensu stricto) is given. The genus Cassidina is redescribed. Three new genera are established: Agostodina gen. nov. (type species: A. munta sp. nov.), Apemosphaera gen. nov. (type species: A. naranagi sp. nov.) and Discidina gen. nov. (type species: D. banawarra sp. nov.). New diagnoses are provided for the genera Cassidina Milne Edwards, Chitonopsis Whitelegge, Cassidinidea Hansen, Paracassidina Baker, Syncassidina Baker and Platysphaera Holdich and Harrison. The genus Dies is placed in synonymy with Cassidinidea and an annotated list is given of all species of the genus. The following new species (excluding the new type species) are described: Chitonopsis booyoolie, Agostodina munta, Paracassidina anasilla, P. bakeri, P. bamarook, P. bilbie, P. cervina, P. dama, P. fuscina, P. incompta, P. kutyo, P. munna, P. petala, P. prolata, P. wurrook and Cassidinidea korpie. Keys to the Australian genera and species are given.
