Cestodes of birds from the Ivory Coast. Species of the genus Anonchotaenia Cohn, 1990

Five taxa included in the cestode genus Anonchotaenia (Cyclophyllidea, Paruterinidae) have been found in various birds from the Ivory Coast (West Africa). The hosts belong to the families Hirundinidae and Corvidae. A. (Paranonchotaenia) prionopos n. sp., parasitic in Prionops plumata, and A. (P.) malaconoti n. sp, parasitic in Malaconotus blanchoti, are placed in a new subgenus named Paranonchotaenia, which is erected for the Anonchotaenia species showing genital ducts passing between the longitudinal excretory stems. A. (P.) prionopos is characterised by a rather short cirrus-pouch, six to seven testes, and an integumental cavity at the distal extremity of the cirrus-pouch in gravid proglottides. A. (P.) malaconoti differs from the former species mainly by the larger cirrus-pouch and a slightly greater number of testes. The other three species are A. longiovata, parasitic in Hirundo semirufa; A. globata, parasitic in Psadiloprocne obscura (the latter two species are recorded from new hosts and new geographical areas); and Anonchotaenia sp., parasitic in Hirundo rustica. It is assumed that the subgenus A. (Anonchotaenia) is rather a parasite of the Passerida and that the subgenus A. (Paranonchotaenia) tends to be parasitic in the Corvida.This paper is a part of the author's thesis.This paper is a part of the author's thesis.     

A taxonomic revision of Labiostrongylus (Labiostrongylus) (Yorke & Maplestone, 1926) and Labiostrongylus (Labiomultiplex) n. subg. (Nematoda: Cloacinidae) from macropodid and potoroid marsupials

The morphological characters used to differentiate species in the genus Labiostrongylus Yorke & Maplestone, 1926, parasitic in macropodid and potoroid marsupials, are discussed. The genus is divided into three subgenera Labiostrongylus (Labiostrongylus), L. (Labiomultiplex) n. subg. and L. (Labiosimplex) n. subg. on the basis of the presence or absence of interlabia and the morphology of the oesophagus. A key to the subgenera is given and a detailed revision of two of the subgenera is presented. Keys to each of the subgenera are given, the species discussed being: L. (L.) labiostrongylus) (type-species) (syn. L. (L.) insularis, L. (L.) grandis, L. (L.) macropodis sp. inq. and L. (L.) nabarlekensis n. sp., in the subgenus Labiostrongylus, and L. (Lm.) eugenii, L. (Lm.) novaeguineae, L. (Lm.) onychogale, L. (Lm.) uncinatus, L. (Lm.) billardierii n. sp., L. (Lm.) constrictis n. sp., L. (Lm.) kimberleyensis n. sp., L. (Lm.) thylogale n. sp., and L. (Lm.) potoroi, n. sp., in the subgenus Labiomultiplex.     

The species of Ibidoecus (Phthiraptera) on Threskiornis (Aves)

The species of Ibidoecus parasitic on the Ibis genus Threskiornis are reviewed-clausus (Giebel), dianae Tandan, insularis sp.n., tandani sp.n., threskiornis Bedford-and a key for their identification presented. The host and geographical distribution of the phthirapteran parasites of this genus are discussed.     

Phylogeny and biogeography of Carminator (Hymenoptera: Megalyridae)

Carminator Shaw is a small genus of parasitic wasps that is mainly distributed in Southeast Asia. Eight species are recognized here, including Carminator coronatus sp.n. and Carminator gracilis sp.n. A data set comprising 54 morphological characters and including all the known species of Carminator, as well as four out‐group taxa (two Cryptalyra spp., one Ettchellsia sp. and one Megalyra sp.), was assembled and analysed. Carminator is retrieved as monophyletic. All weighted analyses place Carminator affinis as the sister group to the rest of the genus. A northern clade comprising species occurring on the Japanese Isles, Taiwan and Vietnam (Carminator japonicus (Carminator gracilis sp.n. (Carminator cavus + Carminator helios))) is strongly supported and nested inside the more southerly distributed species. C. helios is found on Nakanoshima Island, which emerged post‐Pliocene, and so C. helios is considered to have dispersed there via a land‐bridge connection from the Ryukyu Islands. A key to all known species of Carminator is provided.     

Two New Species of Trypanosomatid Parasites Isolated from Heteroptera in Costa Rica

ABSTRACT. Two new trypanosomatid species (Euglenozoa, Kinetoplastea) isolated from the intestinal tract of heteropteran insect hosts were described based on molecular phylogenetic analyses of Spliced Leader (SL) RNA gene repeats, glycosomal glyceraldehyde phosphate dehydrogenase, and small subunit ribosomal RNA genes, as well as by morphology. Leptomonas barvae n. sp., from a mirid host Collaria oleosa, was found to represent one of the closest monoxenous (one host) relatives of the dixenous (two hosts) parasitic genus Leishmania. This finding further supports the origin of these dixenous parasites from monoxenous progenitors in the Neotropics. Blastocrithidia largi n. sp., from a largid host Largus cinctus, is among a few members of this genus available in culture. The species is a close relative of Blastocrithidia triatomae and is a member of a new monophyletic phylogenetic group characterized by formation of straphanger cysts.     

Three species of <Emphasis Type="Italic">Skrjabinelazia</Emphasis> Sypliaxov, 1930 (Nematoda: Seuratidae) parasitic in Gekkonidae and Lacertidae from South Africa,Europe and Australia

Skrjabinelazia Sypliaxov, 1930 comprises 10 species distinguished by several characters typical of the genus including, among the most important, the presence/absence of spicules, cuticle ornamentation and vesicles, head-shape, the presence/absence of a leaflet crown in the buccal cavity, female tail-shape and male cone-shape. The three samples studied are new species: S. boomkeri n. sp., a parasite of Pachydactylus turneri, Gekkonidae, from South Africa (Klaserie Reserve); S. vozae n. sp., a parasite of Lacerta vivipara, Lacertidae, from France (Cévennes), which is close to two lacertid parasites, S. taurica Sypliaxov, 1930 and L. hoffmanni Li, 1934, respectively from the Crimea and North China (Peking); and S. mawsangelae n. sp. (male unknown), a parasite of Christinus marmoratus, Gekkonidae, from Australia (Pearson Island), which is, surprisingly, distinct from Skrjabinelazia sp. of Angel & Mawson (1968) from the same host in another region (North of Adelaide) of South Australia. Two main groups are distinguished in Skrjabinelazia: the species with spicules which are parasitic in the Lacertidae, and the species with a gubernaculum only which are parasitic in the Gekkonidae. The unique species described from the Iguanidae, S. intermedia (Freitas, 1940) from Brazil (Para), also without spicules, seems to be derived from gekkonid parasites, as it also has an evolved oesophagus with a glandular region, unlike the simple oesophagus seen in the larval stages of Skrjabinelazia.     

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.     

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.     

Molecular Phylogeny of the Parasitic Dinoflagellate Chytriodinium within the Gymnodinium Clade (Gymnodiniales,Dinophyceae)

The dinoflagellate genus Chytriodinium, an ectoparasite of copepod eggs, is reported for the first time in the North and South Atlantic Oceans. We provide the first large subunit rDNA (LSU rDNA) and Internal Transcribed Spacer 1 (ITS1) sequences, which were identical in both hemispheres for the Atlantic Chytriodinium sp. The first complete small subunit ribosomal DNA (SSU rDNA) of the Atlantic Chytriodinium sp. suggests that the specimens belong to an undescribed species. This is the first evidence of the split of the Gymnodinium clade: one for the parasitic forms of Chytriodiniaceae (Chytriodinium, Dissodinium), and other clade for the free‐living species.     

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.     

Two new species of Duplicibothrium Williams & Campbell, 1978 (Tetraphyllidea: Serendipidae) from the Pacific cownose ray Rhinoptera steindachneri

Two new tetraphyllidean species, Duplicibothrium cairae n. sp. and D. paulum n. sp., are described from Pacific cownose rays Rhinoptera steindachneri collected from the Gulf of California. D. cairae n. sp. differs from the only other known species in this genus, D. minutum, in its possession of two posteriorly bifurcating longitudinal septa on each bothridium and having a greater number of loculi per bothridium, wider bothridia and a greater number of segments per worm. D. paulum n. sp. differs from the above two species in being shorter, having two continuous longitudinal septa on each bothridium, rather than posteriorly bifurcating or absent longitudinal septa, having a greater number of loculi per bothridium and having fewer segments per worm. The generic diagnosis of Duplicibothrium is amended to reflect the inclusion of the two new species. Species of Duplicibothriumappear to be restricted to host species of the genus Rhinoptera. Systematic information gained from the study of these two new species supports the monophyly of the tetraphyllidean family Serendipidae and suggests that Duplicibothrium shares a phylogenetic heritage with species in the genera Glyphobothrium and Serendip, taxa that are also parasitic in cownose rays. Evidence for a phylogenetic relationship between serendipid species and species of Dioecotaenia is discussed, as are potential molluscan hosts for cestode species in Duplicibothrium and Dioecotaenia.     

The species of Ardeicola (Phthiraptera) on Threskiornis (Aves)

The species of Ardeicola parasitic on the Ibis genus Threskiornis are reviewed-clayae Brelih, freemani sp.n., ibis Le Souef & Bullen, indicus Brelih, intermedia sp.n., nippon Hajela & Tandan-and a key for their identification is presented. Notes on the affinities of the species and a discussion on the distribution of Ardeicola on Threskiornis are included.     

New Laboulbeniales (Ascomycota) parasitic on Staphylinidae from Ecuador

Nine new species of Laboulbeniales parasitic on Staphylinidae from Ecuador are described and illustrated. These are: Corethromyces palumboi, parasitic on Sepedophilus sp. (Tachyporinae); Diandromyces onorei, parasitic on Hypotelus sp. (Piestinae); Dimeromyces osellae, parasitic on Plesiomalota cotopaxiensis Pace (Aleocharinae); Dimorphomyces carolinae, parasitic on Parosus sp. (Oxytelinae); Kleidiomyces ambiguus, parasitic on Anotylus sp. (Oxytelinae); Mimeomyces gregarius, parasitic on Philonthus sp. (Staphylininae); Monoicomyces trogacti, parasitic on Trogactus sp. (Oxytelinae); Scaphidiomyces pusillus, parasitic on Baeocera sp. (Scaphidiinae); and Teratomyces heterothopsis, parasitic on Heterothops sp. (Staphylininae).     

To the knowledge of the leaf-beetle tribe Nodinini (Coleoptera,Chrysomelidae, Eumolpinae) from the Philippines and Borneo

Three new species of the genus Tricliona are described from the Philippines and Borneo Island: T. bakeri sp. n., T. sandakana sp. n., and T. philippina sp. n. Stethotes aedilis Weise are transferred to the genus Cleoporus, and Stethotes ferruginea Weise, to Tricliona. Typophorus quadrimaculatus Baly is transferred to Cleoporus, and C. cruciatus Lefèvre is synonymized with it. The genus Coniomma Weise is redescribed. For each species, drawings of the genitalia are provided. The species of Cleoporus from the Philippines and all the species of the Tricliona ferruginea group are keyed.     

Rhabdias rhampholeonis n. sp. and Rhabdias mariauxi n. sp. (Nematoda, Rhabdiasoidea), first lung worms from leaf chameleons: Description, molecular evidence and notes on biology

Rhabdias rhampholeonis n. sp. from Rhampholeon (Rh.) spectrum, Cameroon, and Rhabdias mariauxi n. sp. from Rieppeleon brevicaudatus, Tanzania, are the first lung worms from leaf chameleons. The new species are similar to the majority of species parasitic in chamaeleonids by having a long (≥10 mm) and thick body (≥500 µm), long oesophagus (≥800 µm), wide buccal capsule (≥40 µm) and low buccal ratio (<0.5). They most closely resemble Rhabdias chamaeleonis and Rhabdias cristati parasitic in Trioceros spp. from East Africa and Cameroon, respectively. Main distinctive characters are a buccal capsule composed of two segments and the head shape. The dorso-ventrally flattened buccal capsule of R. mariauxi n. sp. is unique in Rhabdias parasitising Chamaeleonidae. Sequences of the 12S rDNA and mitochondrial cytochrome c oxidase subunit 1 (coxI) genes were obtained and compared to those of Rhabdias okuensis, the only sequences published for chamaeleonid lung worms. The smallest nucleotide interspecific distances were found between R. mariauxi n. sp. and the former species of Trioceros from Cameroon. Hermaphroditism in females in the lungs, and R. mariauxi n. sp. free-living stages are like in other species from Chamaeleonidae, but the number of infective larvae produced per free-living female (one or two) was not fixed.     

The American scale insect genus Udinia De Lotto (Coccidae)

Udinia, an Ethiopian coccid genus, is redefined and a key is given to the thirteen species now recognised: bruncki sp. n. , catori (Green) comb. n. [= Lecanium subhirsutum Newstead syn. n. ], farquharsoni (Newstead) [= U.exoleta (De Lotto) syn. n. ], glabra De Lotto, ikoyensis sp. n. , lobayana (Balachowsky & Ferrero) comb. n. , newsteadi sp. n. , nigeriensis sp. n. , pattersoni sp. n. , paupercula De Lotto, pterolobina De Lotto, scitula De Lotto, setigera (Newstead). Five species are described as new and three species are redescribed and for these lectotypes are designated. The morphological characters used are discussed and listed and intraspecific variations shown by two of the species are tabulated. The distribution of all the species is recorded on two maps and the literature dealing with associations between ants and Udinia and related coccid genera is briefly reviewed.     

A new species of Thysanote Krøyer, 1863 (Copepoda,Lernaeopodidae) from the Persian Gulf,with comments on the genus

Summary Thysanote alternans n. sp., a lernaeopodid copepod parasitic on Polynemus sextarius is described and illustrated. A key to 19 species of Thysanote is provided (two unnamed species included). Specific diagnosis within the genus is based on the number and shape of maxillary and posterior trunk processes. The limitations of their value as discriminant characteristics are discussed. Host affiliations of the members of the genus are examined. Distribution of Thysanote is shown to have two centres, one in the Indian Ocean and another, a smaller one, in the Caribbean. The connections between them are tenuous. ac]19810127
