Six species of strigeoid trematodes are reported from Malaysia. One new genus and 3 new species are described: Apatemon (Apatemon( jamesi sp. n (Strigeidae); cercaria Cotylurus sullivani sp. n. (Strigeidae); Neodiplostomum (Neodiplostomum) sp. (Diplostomatidae); Fibricola ramachandrani (Diplostomatidae); Pseudoscolopacitrema otteri gen. n. et sp. n. (Diplostomatidae); and cercaria Cyathocotyle malayi sp. n. (Cyathocotylidae). The life cycles of A. jamesi and C. malayi have also been investigated.     

A revision of the Oriental stonefly genus Phanoperla (Plecoptera: Perlidae)

The genus Phanoperla (=Dyaperla Banks, 1939) (Plecoptera: Perlidae: Perlini) is revised and generic diagnoses are provided for adults and larvae. Diagnostic and constitutive characters of the tribe Neoperlini are discussed, and Chinoperla Zwick, 1980, is shown to be the closest relative of Phanoperla. Many past misidentifications of Phanoperla species have been corrected by the use of characters recently recognized as important, namely the structure of the internal genitalia of male and female specimens and particularly the complex pattern of spines on the male penial sac made visible by eversion of this structure, and details of sculpturing of the egg chorion.
The following species of Phanoperla are recognized: amorpha sp.n.; anomala (Banks, 1939); bakeri (Banks, 1924); ceylonica Kawai, 1975; comuta sp.n.; flaveola (Klapálek, 1921), comb.n. ( =clarissa (Banks, 1913), syn.n.), (=Neoperla hageni Banks, 1920, syn.n.), (= N.consimilis Banks, 1924, syn.n.); guttata sp.n.; himalayana Zwick, 1977 (= siwalika Harper, 1977); limosa (Hagen, 1858); maculata sp.n.; maindroni (Navas, 1926), comb.n.; malayana sp.n.; minutissima (Enderlein, 1909); nana sp.n.; nervosa Banks, 1939; nuwara Kawai, 1975; omega sp.n.; pallipennis (Banks, 1938); parva sp.n.; pumilio (Klapálek, 1921), comb.n.; peniculus Kawai, 1969a; schmidi sp.n.; sertispina Jewett, 1975; srilanka sp.n.; sumatrae sp.n.; testacea (Hagen, 1858); wedda sp.n. P.claggi (Banks, 1938) is a nomen nudum.
All species are (re-)described and figured; all primary types have been examined. A key to species is provided. Most species can be assigned to one of seven species groups which are defined.
Phanoperla is endemic to the Oriental Region. Species groups are generally widespread, but individual species are in most cases known only from restricted areas.     

New species of Laboulbenia from Ecuador, with evidence for host switch in the Laboulbeniales

Ten new species of Laboulbenia from Ecuador are described. These are L. barraganii, parasitic on Platamops sp. (Salpingidae); L. biformis, parasitic on Diploharpus rossii Moret (Carabidae); L. davidsonii, parasitic on Odontocheila spp. (Carabidae); L. gregaria, parasitic on Philonthus sp. (Staphylinidae); L. micrandra, parasitic on Lobrathium sp. (Staphylinidae); L. mycotreti, parasitic on Mycotretus spp. (Erotylidae); L. opima, parasitic on Chrysodinopsis sp. (Chrysomelidae); L. otongaensis, parasitic on Diploharpus iridescens Moret (Carabidae); L. tapiae, parasitic on Priocera sp. (Cleridae); and L. trogacti, parasitic on Trogactus sp. (Staphylinidae). Laboulbenia barraganii is the first of the Laboulbeniales to be reported on beetles of the family Salpingidae. L. biformis displays a moderate dimorphism associated with the position on the host insect. L. davidsonii, which is very different from the other species of Laboulbenia reported so far on the Cicindelinae but similar to a group of species parasitic on Galerita spp., provides evidence for the occurrence of host switch in Laboulbeniales.     

A world revision of Strobilomyia gen.n.: the anthomyiid seed pests of conifers (Diptera: Anthomyiidae)

Abstract. The world species of anthomyiid cone and seed pests are revised. A new genus, Strobilomyia gen.n., is erected for the eighteen species, including seven new to science, presently recognized. Author's views on homologies in the male and female terminalia of Anthomyiidae and other Diptera Cyclorrhapha are amplified as background for the terminology employed. The monophyly and systematic position of Strobilomyia are discussed with reassessions of related genera: Lasiomma Stein, Chirosia Rondani, Egle Robineau-Desvoidy and Acklandia Hennig. Zoogeographic aspects, especially vicariance across the Beringia, are analysed from a partial hypothesis of phylogenetic relationships among the species of Strobilomyia in conjunction with paleo-environmental data. New generic synonyms are: Macrophorbia Malloch, Crinurina Karl, Si-nohylemya Hsue (all =Lasiomma); Acrostilpna Ringdahl, Shakshainia Suwa, Meliniella Suwa (all =Chirosia). The species recognized in Strobilomyia (with geographic range and host trees in parentheses) are: anthracina (Czerny) (Palearctic, Picea); neanthracina sp.n. (Nearctic, Picea and ITsuga); appalachensis sp.n. (E. Nearctic); melania (Ackland) (Europe, Larix); sibirica sp.n. (N.E. Europe, Siberia, Larix); viaria (Huckett) (E. Palearctic, Nearctic, Larix); infrequens (Ackland) (Palearctic, Larix); luteoforceps (Fan & Fang) (E. Palearctic, Larix); baicalensis (Elberg) (E. Palearctic, Larix); laricicola (Karl) (Palearctic, Larix); laricis sp.n. (Nearctic, Larix); macalpinei sp.n. (W. Canada, Larix); carbonaria (Ringdahl) (C. Europe, E. Nearctic, Abies); svenssoni sp.n. (N. Europe, Mongolia); suwai sp.n. (Japan); todocola (Suwa) (Japan, Abies); abietis (Huckett) (Nearctic, Abies); and oriens (Suwa) (E. Palearctic, Abies).

Helminth parasites of Chapalichthys encaustus (Pisces: Goodeidae), an endemic freshwater fish from Lake Chapala, Jalisco, Mexico

A total of 6 helminth species were recorded during helminthological examination of 50 Chapalichthys encaustus from Lake Chapala, Jalisco, Mexico. Helminth species identified included: Salsuginus sp. (an undescribed monogenea); Posthodiplostomum minimum (metacercariae); Cyclustera ralli (metacestode); Polymorphus brevis (cystacanth); Contracaecum sp. (nematode larvae); and Rhabdochona lichtenfelsi (adult nematode). Of these, 2 (Salsuginus sp. and R. lichtenfelsi) are specialist species. The observed species richness, individual parasite abundance, and diversity were low. Data suggest that host specificity is an important factor contributing to observed community composition and richness. Host feeding habits and helminth species availability seem to determine the characteristics of these helminth assemblages.     

A new citrus-feeding psyllid from the Comoro Islands, with a review of the Diaphorina amoena species group (Homoptera)

ABSTRACT. Analysis of host plant data for the seventy-one species of Diaphorina shows the genus to be unusually polyphagous, the species developing on eighteen families of dicotyledonous angiosperms. Apart from the common Asian citrus pest, Diaphorina citri , a second citrus-feeding species is described and discussed. This species belongs to the amoena species-group which is defined and a key to nine of the ten included species is given. Seven new species are described: flavipennis sp.n. and nigripennis sp.n. from East Africa on Strychnos usambarensis; huila sp.n. from Angola on Ptaeroxylon obliquum; turned sp.n., from South Africa (host unknown); orantimina sp.n. from Madagascar (host unknown); auberti sp.n. from Comoro Islands on citrus trees; and bispinulata sp.n. from Madagascar (host unknown).     

Revision of the 'nudidrosophila' and 'ateledrosophila' species groups of Hawaiian Drosophila (Diptera: Drosophilidae), with descriptions of twenty-two new species

Abstract.  The 'nudidrosophila' and 'ateledrosophila' species groups, formerly described as genera, are a relatively small and understudied part of the enormous Hawaiian Drosophila radiation. Only nine species were described previously. Here we revise the two groups, provide a key to males and females, and describe fully all species. The 'ateledrosophila' group now contains three species, D. diamphidia Hardy, D. papala sp.n. , and D. preapicula Hardy. The 28 species of the 'nudidrosophila' group are separated into five subgroups: 'hirtitibia' ( D. hirtitibia Hardy, D. konaensis sp.n. , D. mawaena sp.n. , and D. papaalai sp.n. ); 'kahania' ( D. kahania sp.n. and D. longipalpus sp.n. ); 'nudidrosophila' ( D. aenicta Hardy, D. amita Hardy, D. canavalia sp.n. , D. eximia Hardy, D. gemmula Hardy, D. kualapa sp.n. , D. lepidobregma Hardy, D. mahui sp.n. , D. malele sp.n. , D. panoanoa sp.n. , and D. poonia sp.n. ); 'okala' ( D. akoko sp.n. , D. kuhao sp.n. , D. makawao sp.n. , D. okala sp.n. , and D. panina sp.n. ); and 'velata' ( D. halapepe sp.n. , D. kauaiensis sp.n. , D. lauoho sp.n. , D. milolii sp.n. , D. pohaka sp.n. , and D. velata Hardy).     

Free-living marine Rhabdocoela (Platyhelminthes) from the N. American Pacific coast. With remarks on species from other areas

From the N. American Pacific coast the following taxa are described: Coronopharynx pusillus Luther, Pogaina bicornk sp.n., P. paranygulgus sp.n. (Provorticidae); Brinkmanniella palmata sp.n., Tvaerminnea karlingi pucifica subsp.n. (Promesostomidae); Trigonostomum setigerum O. Schmidt, Messoplana pacifica sp.n., Ceratopera axi (Riedl), C. ehlersi sp.n., C. pilifera sp.n. (Trigonostomidae); Polycystis ali Schockaert, P. hamata sp.n. (Polycystididae). From other areas: Brinkmanniella palmata from the Skagerrak, Black Sea and Mediterranean Sea; Ceratopera axi from the Falkland Islands; Polycystis ali from Galapagos Islands; Ceratopera bermudensis sp.n. from Bermuda. Polycystis ali is considered to be a polytypic species with the forms 'Somali', 'California' and 'Galapagos'. Brinkmanniella augusti Marcus and B. falklandica Westblad are considered to be species incertae sedis. Problems in penetrating the world-wide marine turbellarian fauna are discussed.     

Metazoan parasites of Sebastes capensis from two localities in northern Chile as tools for stock identification

Examination of 290 red rockfish Sebastes capensis from two fishing grounds in northern Chile (Coquimbo 71°30' W; 30°0' S and Antofagasta 70°40' W; 23°30' S) revealed 8770 metazoan parasites, belonging to 18 taxa: Udonella caligorum (Udonellidae); Interniloculus chilensis , Paramicrocotyle sp. and Neobenedenia melleni (Monogenea); larval Gnathia sp., Cirolana sp. and Rocinela sp. (Isopoda); Helicometrina nimia , Diphtherostomum sp., Lecithochirium sp. and Pseudopecoelus sp. (Digenea); Ascarophis sebastodis , Anisakis sp. and larval Hysterothylacium sp. (Nematoda); Caligus cheilodactylus , Lepeophtheirus chilensis and Trifur tortuosus (Copepoda); larval Corynosoma australe (Acanthocephala). Ten species were found only in Coquimbo and three were found only in Antofagasta, species common to both localities were Pseudopecoelus sp., C. australe , Anisakis sp. and A. sebastodis . Evidence, based on qualitative differences between the parasite faunas of the red rockfish, suggests the existence of two discrete stocks.

Opisthobranchiate Mollusca from Ghana: Chromodorididae

Nine species of the opisthobranch family Chromodorididae are described from Ghana: Cadlina evelinae Marcus; C. rumia Marcus; C. dubia sp. nov.; Chromodoris ghanensis (Edmunds); C. kpone sp. nov.; C. luleorosea (Rapp); Hypselodoris tana sp. nov.; H. bilineata (Pruvot-Fol) and Mexichromis tricolor (Cantraine). The small number of species found belonging to this warm-water family is attributed to the cold water of the Benguela current.     

New species and new combinations in the yeast genera Kregervanrija gen. nov., Saturnispora and Candida

Analysis of nucleotide sequences from the domains 1 and 2 of the large-subunit rDNA demonstrated species of the Pichia fluxuum clade to be phylogenetically isolated, and domains 1 and 2 and internal transcribed spacer rDNA sequence analyses of strains phenotypically identified as P. fluxuum resulted in the discovery of three new species. From this work, the following new genus, new species, and new combinations are proposed: Kregervanrija gen. nov.; type species Kregervanrija fluxuum comb. nov. (type strain NRRL YB-4273, CBS 2287); Kregervanrija delftensis comb. nov. (type strain NRRL Y-7119, CBS 2614); Kregervanrija pseudodelftensis sp. nov. (type strain NRRL Y-5494, CBS 10105); Saturnispora besseyi comb. nov. (NRRL YB-4711, CBS 6343); Saturnispora mendoncae sp. nov. (type strain NRRL Y-11515, CBS 5620); and Candida abiesophila sp. nov. (type strain NRRL Y-11514, CBS 5366).     

Advances in the Taxonomy of Spiders in Miocene Amber from the Dominican Republic (Arthropoda: Araneae)

Trachelas poinari sp. nov. (Corinnidae), Miagrammopes sp. indet. (Uloboridae) and the first indisputable fossil Lycosidae (gen. et sp. indet.) are newly identified and described in Miocene amber from the Dominican Republic. The following are junior synonyms: Nops segmentatus Wunderlich, 1988 of N. lobatus Wunderlich, 1988 (Caponiidae); Azilia muellenmeisteri Wunderlich, 1988 of A. hispaniolensis Wunderlich, 1988 (Tetragnathidae); and Lyssomanes galianoae Reiskind, 1989 of L. pristinus Wunderlich, 1986 (Salticidae). The specimens described as Nops sp. (Caponiidae), Selenops beynai Schawaller, 1984, S. sp. 1, and S. sp. 2 (Selenopidae) by Wunderlich (1988) are unrecognizable as distinct species. The following new combinations are presented: gen. indet. clypeatus (Wunderlich, 1988) (= Anelosimus clypeatus ) (Theridiidae); Meioneta bigibber (Wunderlich, 1988) (= Agyneta bigibber ), M. fastigata (Wunderlich, 1988) (= Agyneta fastigata ), M. separata (Wunderlich, 1988) (= Agyneta separata ) (Linyphiidae); Enacrosoma verrucosa (Wunderlich, 1988) (= Cyclosa verrucosa ) (Araneidae); Pseudosparianthis pfeiferi (Wunderlich, 1988) (= Tentabunda pfeiferi ) (Sparassidae). Theridion wunderlichi nom. nov. is proposed as a replacement name for T. ovale Wunderlich, 1988 (nom. preocc.). The previously unknown male of Styposis pholcoides Wunderlich, 1988 (Theridiidae) is described. Additional features of Argyrodes crassipatellaris Wunderlich, 1988 (Theridiidae) are described; this species is transferred from the trigonum to the cancellatus species group. Nine specimens belonging to six previously described species, and six juvenile Selenops sp. (including one exuvium) are newly identified. These are the first fossil records of Trachelas, Enacrosoma and Pseudosparianthis, giving them stratigraphic ranges of 15–20 my; the genera Anelosimus, Cyclosa and Agyneta are unknown in the fossil record.     

Some Antarctic Entoprocta with Notes on Morphology and Taxonomy in the Entoprocta in General

-Six entoprocts are reported and figured from the Antarctic Region, collected by the Swedish Antarctic Expedition 1901–1903. The species are: Barentsia discreta (Busk, 1886), Pedicellina cernua (Pallas, 1774), Loxosomella antarctica sp.n., Loxosomella murmanica (Nilus, 1909), Loxosomella compressa Nielsen & Ryland, 1961, subsp. antarctica ssp.n., and Loxosomella brachystipes sp.n. The original diagnosis by Robertson of the genus Myosoma is discussed on the basis of the muscle strands in the calyx and the stalk.     

World species of the genus Platyscelio Kieffer (Hymenoptera: Platygastridae)

The genus Platyscelio Kieffer (Hymenoptera: Platygastridae, Scelioninae) is a widespread group in the Old World, found from West Africa to northern Queensland, Australia. The species concepts are revised and a key to world species is presented. The genus is comprised of 6 species, including 2 known species which are redescribed: Platyscelioafricanus Risbec (Benin, Cameroon, Central African Republic, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Kenya, Mozambique, Nigeria, Sierra Leone, South Africa, Tanzania, Togo, Uganda, Yemen, Zimbabwe); and Platysceliopulchricornis Kieffer (Australia, Bangladesh, China, India, Indonesia, Japan, Malaysia, Papua New Guinea, Philippines, Solomon Islands, Taiwan, Thailand, Vanuatu, Vietnam). Five species-group names are considered to be junior synonyms of Platysceliopulchricornis: Platyscelioabnormis Crawford syn. n., Platysceliodunensis Mukerjee syn. n., Platysceliomirabilis Dodd syn. n., Platysceliopunctatus Kieffer syn. n., and Platysceliowilcoxi Fullaway. The following species are hypothesized and described as new taxa: Platyscelioarcuatus Taekul & Johnson, sp. n. (Western Australia); Platysceliomysterium Taekul & Johnson, sp. n. (Zimbabwe, Botswana, South Africa); Platysceliomzantsi Taekul & Johnson, sp. n. (South Africa); and Platysceliostriga Taekul & Johnson, sp. n. (Western Australia).     

The effects of periodic eutrophication on parasitism and stock identification of Trematomus bernacchii (Pisces: Nototheniidae) in McMurdo Sound, Antarctica

McMurdo Sound, Antarctica, is suited for the study of the effects of eutrophication on diet-related parasites of Trematomus bernacchii (Boulenger, 1902) (Pisces). It has been relatively well studied, the environment is predictable, and there are significant differences in primary productivity over small distances. The differences in parasitism for 5 helminth species can be attributed to the enrichment processes in the sound. The prevalences of the acanthocephalan Echinorhynchus sp., the nematode Ascarophis nototheniae, the digenean Dinosoma sp., and the cestode Phyllobothrium sp. are significantly higher on the east side of the sound than on the west. The prevalence of the digenean Lepidepedon garrardi was significantly higher on the west side. We believe that the differences in the prevalences of infection between the east and west sides suggest that at least the benthic, adult fish do not readily move from one side of the sound to the other. We report the following (new host records are marked by asterisks): Echinorhynchus sp., Corynosoma hamanni (Acanthocephala); Phyllobothrium sp., Diphyllobothrium sp., Trypanorhyncha (Cestoidea); Clavellopsis (Copepoda); Dinosoma sp., Lepidepedon garrardi (Digenea); Pseudobenedenoides brachicola, Polyopisthocotylea (Monogenea); Contracaecum sp., Ascarophis nototheniae (Nematoda); Myxoproteus sp., Henneguya sp., Ceratomyxa sp., and Zschokkella sp. (Protozoa).
