First report of Litomosa spp. (Nematoda: Filarioidea) from Malagasy bats; review of the genus and relationships between species

The presence of the filarial genus Litomosa in Malagasy bats is demonstrated by the finding of L. goodmani n. sp. from Miniopterus gleni and Litomosa sp. (male unknown) from M. manavi, both in the Special Reserve of Ankarana. These materials are compared to the 22 Litomosa species, including two Indian species originally placed in the genus Litomosoides, L. fotedari (Gupta and Trivedi, 1989) n. comb. and L. tewarii (Gupta and Trivedi, 1989) n. comb., and the new taxon L. seurati n. sp. (= L. beaucournui Bain, 1966 pro parte), type-host Rhinolophus ferrum-equinum, Algeria, distinguished by the narrow area rugosa and the female caudal extremity with two conspicuous points, instead of several small ones. The Malagasy material belongs to a group of species close to the type, L. filaria, which have a male area rugosa composed of cuticular bosses and microfilariae folded within the sheath, and which are parasitic in Vespertilionidae, Hipposideridae and Rhinolophidae from Africa and Europe. The two Malagasy species resemble L. seurati n. sp., L. beshkovi Jancev, 1971, L. chiropterum Ortlepp, 1932, L. adami Petit, 1980 and L. ottavianii Lagrange et Bettini, 1948, with the enlarged third segment of the buccal capsule. L. goodmani n. sp. is distinct with its small size and female caudal extremity with a single point, which is suppressed in old mature worms; the females of Litomosa sp. have two conical points. Relationships among Litomosa species appear to be dependent upon both the chiropteran host groups and the geographical region.     

A new relictual and highly troglomorphic species of Tomoceridae (Collembola) from a deep Croatian cave

Tritomurus velessp. n. (Tomoceridae) is described from a Croatian cave. It is characterized by troglomorphic features (absence of eyes, reduced pigmentation, slender claw, pointed tibiotarsal tenent hairs) that only compare, among Tomoceridae, to the microendemic species Tritomurus falcifer from the Pyrénées. Tritomurus veles also shares with Tritomurus falcifer the absence of macrochaetae on head, a presumably non-adaptive character that within Tomoceridae is unique to these two species. Both species have no known epigean relatives in their respective distribution areas and can be considered as relictual.

Parvicapsula bicornis n. sp. and P. limandae n. sp. (Myxozoa, Parvicapsulidae) in Pleuronectidae (Teleostei, Heterosomata) from Denmark

Two species of Parvicapsula were found in the kidney tubules and the urinary bladder of 2 pleuronectid fish from the northern Oresund, Denmark. The coelozoic, spherical, disporic trophozoites of both species are 10 to 12 pm in diameter. The myxospores of both species are elongate, asymmetrical and slightly curved, and have spherical polar capsules. Parvicapsula bicornis n. sp. (6-8 x 5-6 microm, polar capsule 2.5 microm in diameter) occurs in Pleuronectes platessa. The polar capsules of P. bicornis are arranged symmetrically on either side of the longitudinal axis and its spores differ from other species of Parvicapsula in having two 2-3 microm long posterior processes of different length. Parvicapsula limandae n. sp. (8-11 x 4-5 pm, polar capsule 1.6 microm in diameter) is found in Limanda limanda. The polar capsules are arranged along the longitudinal axis. It differs from Parvicapsula unicornis Kabata, 1962, recorded from L. limanda, in the arrangement of the polar capsules and in the absence of a posterior horn-like projection. The phylogenetic relationship between P. bicornis n. sp., P. limandae n. sp. and other Parvicapsula spp. was examined with their partial small subunit rDNA (SSU rDNA) sequences. P. limandae n. sp. and P. asymmetrica appear to be closely related, while P. bicornis n. sp. and P. minibicornis are the most divergent members of the genus.

From Brotogeris : the type species Pararalichus dilatatus (Favette & Trouessart) stat.n., comb.n. [= Protolichus ( Mesolichus ) hemiphyllus dilatatus ] from Brotogeris jugularis (Müller), Brazil, Guatemala, Panama; P. chrysopteri sp.n. from B. chrysopterus (L.). Guyana, Surinam; P. cyanopterae sp.n. from B. cyanoptera (Pelzeln), Bolivia, Peru; P. pyrrhopteri sp.n. from B. Pyrrhopterus (Latham), Ecuador, Peru; P. sanctithomae sp.n. from B. sanctithomae (Müller), Bolivia, Peru; P. tiricae sp.n. from B. tirica (Gmelin), Brazil; P. versicolori sp.n. from B. versicolorus (Müller), Brazil, Peru. From Touit: P. hemiphyllus (Mégnin & Trouessart) comb.n. [ =Pterolichus (P.) hemiphyllus ] from Touit batavica (Boddaert), Surinam, Trinidad; P. dilectissimae sp.n. thrn T. dilectissima (Sclater & Salvin), Colmbia, Costa Rica; P. huetii sp.n. from T. huetii (Temminck), Brazil, Guyana, Peru; P. parpuratae sp.n. from T. purpurata (Gmelin), Brazil, Guyana, Surinam; P. surdae sp.n. from T. surda (Kuhl), Brazil. All hosts are Central and South American parrots. Mesolichus Trouessart, 1899 is recognized as a monotypical genus.

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.     

Three new genera of Braconini from Australasia and Malaysia (Insecta, Hymenoptera, Braconidae)

Ancilibracon gen.n. (type species: Ancilinracon townesi sp.n.). Ancilibracon bakeri sp.n., Gelasinibracon gen.n. (type species: Gelasinibracon sedlaceki sp.n.), Gelasinibracon simplicicaudatus sp.n., Esengoides gen.n. (type species: Esengoides crentdatus sp.n.) and Esengoides fulvus sp.n. are each described and illustrated. Ancilibracon towensi is from Malaysia. A. bakeri is from Borneo, both Gelasinibracon species are from Guinéa, E. crenulatus is from the solomon Islands and E. fulvus is from Australia. These three new genera belong to the Plesiobrscon Cameron group of the Braconina. Their relationship are discussed.

Biogeography of helminth parasitism in Lemmus Link (Arvicolinae), with the description of Paranoplocephala fellmani n. sp. (Cestoda: Anoplocephalidae) from the Norwegian lemming L. lemmus (Linnaeus)

We describe the gastrointestinal helminth fauna of true lemmings (Lemmus spp., Arvicolinae) based on published and original material throughout the Holarctic range of these hosts. According to the existing data, the helminth fauna of true lemmings consists of three widespread and/or locally common taxa: Hymenolepis horrida (sensu lato) (Hymenolepididae), Anoplocephaloides lemmi (Anoplocephalidae) and Heligmosomoides spp. (Heligmosomidae). Despite the taxonomic boundaries and ancient phylogenetic splits in the hosts, there are no major faunistic differences for parasites within western (Siberian) L. sibiricus and L. bungei, and eastern (North American) L. trimucronatus throughout their distribution range. In contrast, the Norwegian lemming L. lemmus, which is a Fennoscandian endemic and closely related to the western populations of L. sibiricus, has only a single host-specific helminth, the cestode Paranoplocephala fellmani n. sp. (Anoplocephalidae). We describe the new species and show that it differs consistently from related species by its long and slender cirrus-sac. However, there are also a number of other significant differences, e.g., P. fellmani n. sp. and Andrya primordialis in Tamiasciurus hudsonicus (Sciuridae) evidently have a unique (sub)type of uterine development among Andrya/Paranoplocephala spp. Because P. fellmani n. sp. was also found to occur in Alaska (host L. trimucronatus), this species seems to follow the same biogeographical pattern as the other specialist helminths of Lemmus. We suggest alternative explanations for the absence of three major helminth taxa in the Norwegian lemming in Fennoscandia.     

Revision of the Neotropical genus Leptochromus Motschulsky (Coleoptera: Scydmaenidae)

Abstract The Neotropical genus Leptochromus Motschulsky (Coleoptera: Scydmaenidae) is revised, and a phylogenetic analysis of Clidicini is presented. Leptochromus includes five species distributed from Veracruz, Mexico to Manaus, Brazil. Leptochromus fulvescens Motschulsky, L. mexicanus (Sharp) and L. agilis (Sharp) are considered valid species. Leptochromus bicolor O'Keefe, sp.n. from Veracruz, Mexico and L . palaeomexicanus O'Keefe, sp.n. from Miocene amber from Chiapas are described. Male genitalia and antennae are illustrated for each of the extant species. Female genitalia, mouthparts and other morphological features are illustrated for the type species L. fulvescens. For the phylogenetic analysis of Clidicini, Palaeoleptochromus O'Keefe was placed as the sister taxon to Leptochromus , and Papusus Casey was placed as the sister taxon to Leptochromus  + Palaeoleptochromus . Papusus is elevated from synonomy with Leptochromus and the biogeography of Clidicini is discussed.     

Description of a new species of marine amoeba Korotnevella mutabilis n. sp. (Amoebozoa,Dactylopodida)

Korotnevella (Amoebozoa, Dactylopodida) is a genus of naked lobose amoebae with a dactylopodial morphotype. The cell membrane of these amoebae is covered with a monolayer of scales. The structure and size of scales are considered as species-specific features. Here, we describe a new marine species, Korotnevella mutabilis n. sp., isolated from the bottom sediment sample of Nivå Bay (Baltic Sea, The Sound) and studied with light and electron microscopy as well as with molecular phylogenetic analysis. This species has a number of morphological similarities with Korotnevella monacantholepis, such as size of the cell, L/B ratio, the nucleus structure and the type of a biotope from which both species were isolated. At the same time, Korotnevella mutabilis n. sp. differs from K. monacantholepis in the structure of basket-shaped scales: Korotnevella mutabilis n. sp. has an enclosed hammock-shaped latticework basket and up to two spines while K. monacantholepis has an opened two-row latticework basket and never has two spines. According to molecular phylogenetic analyses based on the sequences of the mitochondrial COI gene, Korotnevella mutabilis n. sp. is a distinct species, highly divergent from other Korotnevella species.

Descriptions of Lutzomyia (Evandromyia) georgii n. sp. and a synopsis of the series infraspinosa (Diptera: Psychodidae)

Lutzomyia georgii n. sp. and the female of L. tarapacaensis in the Series infraspinosa of the subgenus Evandromyia are described, from specimens collected in rainforest in the north of the State of Pará, Brazil. The new species was taken together with five other Evandromyia species including L. infraspinosa (sensu strictu) in the same locality. L. georgii has previously been confused with both L. begonae and L. infraspinosa, whereas L. tarapacaensis would run to L. infraspinosa in recent taxonomic keys. The fact that both L. georgii and L. tarapacaensis are locally sympatric with L. infraspinosa helps to clarify the taxonomic limits of the latter species. New keys to the subgenus Evandromyia are provided.     

Lepidapedon spp. (Digenea: Lepocreadiidae) from deep-sea gadiform fishes of the NW Atlantic Ocean,including four new species

Five species are described from fishes in deep waters of the northwestern Atlantic Ocean: Lepidapedon gaevskayae n. sp. from Coryphaenoides (Nematonurus) armatus; L. merretti n. sp. from Phycis chesteri; L. zubchenkoi n. sp. from Coryphaenoides (Chalinura) leptolepis; L. beveridgei n. sp. from C. (N.) armatus; and Lepidapedon sp. innom. from Antimora rostrata. The genus Lepidapedon is discussed and divided into groups of species distinguished by the vitelline distribution and the extent of excretory vesicle. The new species are placed in their appropriate groups and differentiated from the other species in the group.     

Marine Heterotrophic Amoebae, Flagellates and Heliozoa From Belize (Central America) and Tenerife (Canary Islands), With Descriptions of New Species, Luffisphaera Bulbochaete N. Sp., L. Longihastis N. Sp., L. Turriformis N. Sp. and Paulinella Intermedia N. Sp.

ABSTRACT. Thirty four taxa of heterotrophic protists (amoebae, flagellates and heliozoa) were encountered in cultures established from marine samples from Belize (Central America) and Tenerife (Canary Islands). Most species are flagellates drawn from the choanoflagellates, the cryptophyceans, the euglenids, the kinetoplastids, the bicosoecids, the chromulinids, the pedinellids and a variety of laxa of uncertain affinities (Protista incertae sedis). the identity of the thecate choanoflagellates Salpingoeca ringens Kent, 1880, and S. tuba Kent, 1880, is discussed, and four new species of heterotrophic protists are described: one new species of the amoeba genus Paulinella (Paulinella intermedia n. sp.) and three new species of the incertae sedis genus Luffisphaera Belcher & Swale, 1975 ( Luffisphaera bulbochaete n. sp.; L. longihastis n. sp.; L. turriformis n. sp.).
