Australian thrips of the Haplothrips lineage (Insecta: Thysanoptera)

Keys are presented to the 11 genera and 50 species, including 21 new species, of Thysanoptera in Australia that are related to the worldwide genus Haplothrips Amyot and Serville. These taxa belong to what, in recent literature, has been called the “Haplothrips‐lineage”, that is, one of the three major radiations among the 2700 species and 350 genera of Thysanoptera Phlaeothripinae. The group is redefined, and the available tribal name Haplothripini shown to be appropriate. The character states on which the definition is based are discussed, and a list given of the 34 genera worldwide that can be included. The Australian species in these genera exhibit a diversity of biologies. Three genera involve species that invade galls induced by other thrips: Androthrips monsterae (Moulton) from New Guinea is newly recorded from Australia; Mesothrips jordani Zimmermann from South‐East Asia is newly recorded from Australia, with two new synonyms; the Asia‐Pacific genus, Euoplothrips Hood, includes two species in northern Australia. Three haplothripine genera are associated with grasses: one widespread genus, Apterygothrips Priesner, considered polyphyletic, includes only one Australian species; the only known species of Dyothrips Kudo is Oriental but extends into tropical Australia; Podothrips Hood, a circum‐tropical genus of thrips predatory on grass‐living coccoids, has 11 Australian species, six newly described. One grass‐associated genus, Bamboosiella Ananthakrishnan, is excluded from the Haplothripini. An Oriental genus of leaf‐ and flower‐living species, Dolichothrips Karny, includes one species in northern Australia, D. reuteri (Karny); Membrothrips Bhatti in which this species has been placed is considered a synonym. Karnyothrips Watson includes two species introduced to Australia, both predators of coccoids. Priesneria Bagnall includes three species from Australia, of which one fungus‐feeding species is newly described. Xylaplothrips Priesner is a widespread but ill‐defined, polyphyletic genus that currently includes three little‐known Australian species. Haplothrips is the main focus of this study, and character state variation among the Australian species is discussed. In total 24 species of Haplothrips from Australia are recognised, 14 being new species. Also included are the following, one new generic synonym, four new species synonyms, and one new combination. The 250 species worldwide in the genus are usually associated with the flowers of Asteraceae and Poaceae. In Australia, several of the species are specific to flowers, particularly of Poaceae and Cyperaceae but not Asteraceae. Almost half of these Australian species are presumed to be predatory on other small arthropods, and two have unusual host associations—with salt marsh Chenopodiaceae, and with the sori of Dicksonia tree ferns.     

Review of the types of Palola (Eunicidae: Polychaeta)

As part of a review of the types of all currently known species of eunicid poly-chaetes, the genus Palola is reviewed. Nineteen named taxa are here accounted for; of these 12 are tentatively considered valid; the other species are incompletely known, or are considered synonyms of other species or are indeterminable. The number of species suggested in this paper may change once variability and allometric patterns have become better understood.     

High prevalence of blood parasites in hawfinch Coccothraustes coccothraustes

Fifty-seven hawfinches Coccothraustes coccothraustes were caught in May–June 1982–2001 on the Curonian Spit in the Baltic Sea and investigated by microscopical examination of stained blood films. Haemoproteus fringillae, H. tartakovskyi, Leucocytozoon dubreuili, L. fringillinarum, L. majoris, Plasmodium relictum, P. vaughani, Trypanosoma avium, T. everetti, and microfilariae were identified. The overall prevalence of infection was 100%. Prevalences of Haemoproteus spp. (89.5%), Plasmodium spp. (61.4%), Leucocytozoon spp. (78.9%), Trypanosoma spp. (26.3%), and microfilariae (29.8%) were recorded. No differences were discernible in parasite fauna, prevalence, or intensity of infection between males and females or between young and adult birds. The majority of infections (86.0% of all birds) were mixed, with parasites from two to five different genera present in each blood smear. These birds were failed breeders migrating through the Curonian Spit. It is probable that heavy haematozoan infections can influence the breeding success of birds.     

Taxonomic revision of the genus Littorophiloscia Hatch, 1947 (Crustacea,Isopoda, Oniscidea) with description of six new species

In the present revision 15 species of Littorophiloscia are recognized. Six species, namely L. tropicalis, L. koreana, L. amphindica, L. pallida, L. bifasciata and L. hawaiiensis are described as new. Littorophiloscia isabellae (Vandel, 1973) is considered to be a junior synonym of L. albicincta (Vandel, 1973), and Philoscia dartevellei Brian, 1953 and Vandeloscia orientalis Roman, 1977 are considered to be junior synonyms of L. culebrae (Moore, 1901). Alloniscus compar sens. Vandel, 1952 nec Budde-Lund, 1893 is considered to be distinct from L. riedli (Strouhal, 1966) and it has been renamed L. tropicalis sp. nov. The genera Bilawrencia Vandel, 1973, Helenoscia Vandel, 1977, Vandeloscia roman, 1977 and Sayoscia Schultz, 1983 are considered to be synonymous with Littorophiloscia. Diagnostic characters of all the species are illustrated. A map and comments on the distribution of the 15 species are included.     

The world Rhyparochrominae (Hemiptera:Lygaeidae)

Summary

The species of Epitraninae, a subfamily of Chalcididae, parasitic Hymenoptera, are taxonomically revised, from an area including India in the west and New Guinea in the east. Over 500 specimens were studied, including all accessible types. Only one genus, Epitranus Walker, is recognized and its synonymy corrected. A key is given to 29 species of which 17 are described as new and among the earlier names 30 were found to be junior synonyms (and some more are probable synonyms, as suggested in the paper, among the names the types of which were not examined). The treated and illustrated valid species include two from Australia and notes and a figure of another species, E. evanioides, from Mauritius. Two Oriental species were found widely distributed also in Africa: E. observator and E. clavatus. The latter was also recorded in the New World, probably having been inadvertedly introduced. One Oriental species, E. erythrogaster, is not only widely distributed but has an unusual range of variation and may prove to be a composite aggregate when more information is available. Little help could be drawn from the biological data because definite host records are available only for four species.     

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.     

In search of the true Tydeus (Acari,Tydeidae)

The early history of the genus Tydeus, the type genus of the family Tydeidae, is complex and convoluted and, subsequently, even the identity of the type species of the family remains unclear. First, the literature is thoroughly analysed and morphological characters of some species are reappraised. After studying Oudemans' types, two species inquirendae, Tydeus croceus and T. cruciatus, are redescribed and a third, T. spathulatus, removed from synonymy and reinstated as a valid species. A fourth species, confused with T. spathulatus, is described. A lectotype is designated for T. spathulatus and a neotype for T. croceus. After discussion, the genus Lorryia Oudemans, is re‐established in its pristine state. As the redescribed species were designated as type species by Oudemans, the following new generic synonymies are proposed: Raphitydeus Thor, and Lorryia Oudemans, sensu Ka?mierski (, ) are junior synonyms of Brachytydeus Thor, ; Homeotydeus André, (partim) and Pseudolorryia Ka?mierski, are junior synonyms of Calotydeus Oudemans, ; Brachytydeus Thor, (partim), Calotydeus Oudemans, (partim), Tydeus Koch, sensu Oudemans, (partim), Orthotydeus André, , and Tydeus Koch, sensu Ka?mierski, are junior synonyms of Tydeus Koch, . To stabilize the usage of the names, especially that of the genus type of the family Tydeidae, the International Commission of Zoological Nomenclature will be asked to set aside all previous type species designations for Tydeus and to designate Tydeus spathulatus as the type species, with Oudemans' specimens from Italy as primary type material.     

Revision of the genus Caucasocressa from the eastern Pontic Region (Gastropoda: Hygromiidae)

The genus Caucasocressa is revised. Ten Caucasocressa species are known from north-east Turkey and south-west Georgia. Five new species are described. For every taxon the shell is described and illustrated and the variability of the genitalia (as far as known) is shown. All synonyms are listed. The distribution is summarized and all locality records are listed. The distribution of the species is illustrated on a UTM grid-map.     

Revision of the obligate mushroom‐feeding African “dung beetle” genus Coptorhina Hope (Coleoptera: Scarabaeidae: Scarabaeinae)

The African genus Coptorhina Hope is revised. Nine new synonymies are established which reduces the number of valid names from 15 to six. One new species is also described. The name changes are the following: C. subaenea Janssens, C. bicolor Ancey, C. pygmaea Balthasar and C. saganicola Müller are considered junior synonyms of C. nitidipennis Boheman; C. africana Hope, C. vicina Péringuey, C. obtusicornis Boheman, C. punctata Ferreira and C. optata Péringuey are considered junior synonyms of C. klugii Hope. The new species, C. excavata sp. n., is described from southern Africa. A key to the species and notes on biology are given.     

A systematic revision of the large-scaled Marcusenius with description of a new species from Cameroon (Teleostei; Osteoglossomorpha; Mormyridae)

Nine out of 37 recognized species in the genus Marcusenius have eight large circumpeduncular scales rather than 12 or 16, which is more typical of the genus. They are: M. dundoensis, M. fuscus, M. ghesquierei, M. intermedius, M. kutuensis, M. lambouri, M. moorii, M. paucisquamatus and M. schilthuisiae. All nine are restricted to West-Central and Central Africa. A detailed morphometric analysis could not distinguish differences between M. moorii, M. paucisquamatus and M. lambouri. Therefore they are considered as synonyms with M. morrii as the senior synonym. The systematic status of M. intermedius is uncertain owing to the existence of only three specimens. Within this species complex a new species, Marcusenius sanagaensis, is described from the Sanaga River basin in Cameroon. It differs from all the others in the number of scales on the lateral line and in the extent of the broad dark band between the anterior base of the dorsal fin and the anterior base of the anal fin. All valid Marcusenius species with eight circumpeduncular scales are redescribed and a key to these species is given.     

Cladistics and distribution of Euxanthe butterflies (Nymphalidae: Charaxinae)

A cladistic analysis of the 6 species of Euxanthe is given utilizing 15 characters, and the species' geographical distributions discussed in relation to the proposed cladogram. The division of the genus into two subgenera by past revisers is seen to be justified. The relatively rapid anagenesis of E. madagascariensis is considered, and mimicry in the group discussed. A key to the 15 species and subspecies taxa is given, and each is revised. Notes on the biology of the species and subspecies are included, 7 lectotypes are designated and 2 new synonyms established.     

Revision of the genus Erythracarus Berlese (Acarina: Anystidae: Erythracarinae)

The mite genus Erythracarus is revised and redefined and the new pyrrholeucus species group is described. The type species of Erythracarus is established as E. ruricola and the previous designation of Trombidium parietinum as the type is thus declared invalid. Bechsteinia and Chabrieria are newly synonymized with Erythracarus. Nine new species are described: Erythracarus amnicolus n. sp., E. avius n. sp., E. barbarus n. sp., E. ciliatus n. sp., E. decoris n. sp., E. elegans n. sp., E. flavipes n. sp., E. katherinae n. sp. and E. nasutus n. sp. The species E. parietinus, E. pyrrholeucus, E. festinus and E. grahami are redescribed and identification keys to known species and instars of Erythracarus are presented. E. cluozzai is made a junior synonym of Tarsolarkus articulosus, Bechsteinia solarii and Erythraeus spinatus are made junior synonyms of Erythracarus parietinus, while Bechsteinia californica, B. schneideri and Tarsotomus terminalis are all made junior synonyms of E. pyrrholeucus. E. simku is found to be a nomen nudum. E. pyrrholeucus is recorded for the first time from Australia, Iran and the Ukraine and E. parietinus for the first time from the western United States. The only record of E. parietinus from Australia is shown to be based on a misidentification. Observations on reproductive behaviour are made for five Erythracarus species. All of these reproduce sexually by means of stalked spermatophores, the shape of which is species specific. Spermatophores are often deposited on top of one another, possibly indicating sperm competition. Males of one species, E. pyrrholeucus, are unknown and this species is thus likely to be thelytokous. Some Erythracarus species are oviparous. E. ciliatus and E. parietinus are ovoviviparous or viviparous. Prelarvae that were studied were immotile except for those of E. ciliatus, which were able to move their legs. Immotility is a derived character state in Erythracarus and possibly an adaptation to more protected habitats.     

Oribatid mites of Liebstadia (Acari: Oribatida: Scheloribatidae) from Mongolia,with notes on taxonomy of the genus

Three new species of oribatid mites belonging to the genus Liebstadia are described from Mongolia. The new species are characterized by the poorly developed pteromorphae; the club-shaped head of the sensilli; the absence of the dorsosejugal suture; the dorso-ventral thickness, and the length and arrangement of notogastral setae. In addition, L. similis (Michael, 1888) is redescribed and recorded for the first time in Mongolia. Protoribates serratomarginatus Mahunka, 1983 is synonymized with L. similis. A key to the known species of the genus Liebstadia is given.     

A revision of the genus Prionocrangon (Crustacea: Decapoda: Caridea: Crangonidae)

Additional specimens belonging to the rare crangonid genus Prionocrangon Wood‐Mason and Alcock, collected from recent deep‐sea expeditions in the West Pacific enable a revision of this poorly known genus. The four previously described species are all valid. The type species P. ommatosteres Wood‐Mason and Alcock, , originally known only from the Andaman Sea, is considered to be also distributed in the Philippines and Indonesia. However, the material previously assigned to “P. ommatosteres” by de Man () and Chace () from Indonesia and the Philippines actually represents a new species, P. demani sp. nov., close to P. pectinata Faxon, . Prionocrangon pectinata and P. curvicaulis Yaldwyn, are still only known by their types. The distribution of P. dofleini Balss, is now extended from Japan to Taiwan. Two more new species are recognized. Prionocrangon formosa sp. nov. from Taiwan is closely related to P. curvicaulis while P. paucispina sp. nov. from Taiwan and New Caledonia is unique in having very few dorsal carapace spines. The genus Prionocrangon is newly diagnosed and a key to the species is provided. Nevertheless, a damaged specimen from the Sulu Sea could not be satisfactorily assigned to any of the above seven species, suggesting that this genus may have even higher diversity.     

Taxonomy of the genus Oriverutus Siddiqi, 1971 (Nematoda: Dorylaimida: Nordiidae)

After introducing its history, the most relevant morphological features of Oriverutus are explained, illustrated (light and scanning electron microscope pictures) and discussed. The taxonomy of the genus is analysed based on the study of all the nominal species, and an emended diagnosis is provided. Its relationships with the closest genera are discussed, and some reflections are made on its phylogeny. Ecanema and Mammillonema are confirmed as junior synonyms of Oriverutus, Inbionema is regarded as its junior synonym also, whereas Paroriverutus is considered to deserve separate generic status. Consequently, several nomenclatorial changes are derived: Paroriverutus ivorensis is retained under Paroriverutus, Drepanodorylaimus macramphidius and Oriverutus longicaudatus are transferred to Paroriverutus, and Inbionema biforme to Oriverutus. An updated list of Oriverutus species is provided as well as a key to the identification of its didelphic species and a compendium of their morphometrics.     

Water mites of the family Hygrobatidae Koch from southern Africa (Acari: Hydrachnidia)

New records are given of the water mite family Hygrobatidae (without the genus Atractides) from southern Africa (South Africa, Botswana, Namibia). In addition to one new subgenus of the genus Hygrobates, namely Inflatibates, four new species are described, namely Hygrobates draconicus, H. laceratoides, H. okavangoensis, and H. inflatipes as well as one new subspecies, namely Hygrobates spathuliferus cederberg. The following synonyms are established: the subgenus Capobates Thor with Hygrobates Koch, Hygrobates sanguineus transvaalensis K. O. Viets with Hygrobates spathuliferus (Lundblad), and Ambiguobates permixtus agnewi K. O. Viets with Ambiguobates permixtus K. Viets. The male of Australiobates pilosus (K. Viets) is described for the first time. The synonymization of Diversibates with Australiobates can now be confirmed. Finally, keys are given for the known genera of southern Africa, as well as for all known species of the genus Hygrobates from southern Africa.     

A synopsis of Martarega White, 1879 (Insecta: Heteroptera: Notonectidae) occurring in the Brazilian Amazonia,with descriptions of three new species

The genus Martarega comprises 15 species and nine of these have been recorded in northern Brazil. Martarega pydanieli sp. nov. from Rondônia, while Martarega nieseri sp. nov. and M. barcelos sp. nov. from Amazonas are described here. Six known species are recorded in the Brazilian Amazonian Region (Amazonas, Pará, Rondônia and Roraima): M. brasiliensis, M. chinai, M. gonostyla, M. membranacea, M. oriximinaensis, and M. uruguayensis. At the outset of this survey the genus Martarega of the Brazilian Amazonian Region held 12 species, but no specimens of M. mcateei, M. hungerfordi, and M. williamsi were collected in the regions sampled. Martarega brasiliensis is newly recorded from Roraima, which comprises the first record of members of this genus in this State. Martarega uruguayensis is newly recorded from Pará and Rondônia, while M. gonostyla from Rondônia. Distinct keys to males and females of Martarega occurring in this region, including these new species, are provided.     

A revision of Neobenedenia Yamaguti, 1963 (Monogenea: Capsalidae) including a redescription of N. melleni (MacCallum, 1927) Yamaguti, 1963

Neobenedenia Yamaguti, 1963, a genus of capsalid (benedeniine) monogeneans lacking a vagina, is redefined. The generic diagnosis is amended to include previously unused characters like the path of tendons in the haptor from extrinsic muscles in the body, the presence and form of a marginal valve, the shape of the anterior attachment organs, the arrangement of musculature at the posterior (proximal) end of the penis sac and the presence of a pair of sphincters in the female reproductive tract. On this basis, the generic composition is reduced from 10 to six species. Species considered valid are: N. melleni (MacCallum, 1927) Yamaguti, 1963; N. adenea (Meserve, 1938) Yamaguti, 1963; N. isabellae (Meserve, 1938) Yamaguti, 1963; N. longiprostata Bravo-Hollis, 1971; N. muelleri (Meserve, 1938) Yamaguti, 1963; N. pacifica Bravo-Hollis, 1971. Neobenedenia girellae (Hargis, 1955) Yamaguti, 1963 and N. paragueraensis Dyer, Williams and Bunkley-Williams, 1992 are considered synonyms of N. melleni. Species formerly ascribed to Neobenedenia, namely N. manilae Velasquez, 1982 and N. vermiculariacola Gupta and Khanna, 1975 are considered species inquirendae. A key to valid species is presented. The type species, N. melleni, is redescribed based on the original specimens of MacCallum and N. isabellae is redescribed based on material from the type locality. Since no types of N. melleni were designated, a lectotype and paralectotypes are assigned. The problem of host designation and locality for the types of N. melleni sensu MacCallum is discussed. A study of more than 80 specimens now considered to be N. melleni has permitted comments on its apparent variety of forms and its low host-specificity according to the current revision. N. melleni is now recorded from over 100 species of teleosts in more than 30 families from five different orders. Material reported previously as N. melleni off Chile from Seriola mazatlana, Thunnus thynnus orientalis and Seriola sp. are identified here as Benedenia seriolae (Yamaguti, 1934) Price, 1939. The host-specificity and geographic distribution of species in the revised genus is discussed.
