Sergentomyia gobica sp. n. (Diptera, Phlebotominae)--a new species of sandfly from the Mongolian People's Republic

17 males and 7 females of Sergentomyia (Parrotomyia) gobica sp. n. were collected in Tsubulur-Khara-Nuru mountains (Bayan-Khongor region) of the Mongolian People's Republic in August of 1980 and in July of 1982. The new species is similar to S. (Parr.) sumbarica (Perfiliew), 1933.     

First record of Phlebotomine sandflies (Diptera: Psychodidae) in the Comoros Archipelago with description of Sergentomyia (Vattieromyia) pessoni n. sp. and S. (Rondanomyia) goodmani comorensis n. ssp

No Phlebotomine sandflies had ever been reported in the Comoros Archipelago, including the three islands of the Republic of the Union of Comoros (Grande Comore, Mohéli and Anjouan) and the French oversea department of Mayotte. During three field surveys carried out in 2003, 2007 and 2011, we provided the first record of Phlebotomine sandflies in this area. A total of 85 specimens belonging to three species were caught: a new species S. (Vattieromyia) pessoni n. sp. (two females from Grande Comore), a new subspecies of Sergentomyia (Rondanomyia) goodmani (80 specimens from Grande Comore and one from Anjouan) and Grassomyia sp. (two females from Mohéli). The individualisation of these taxa was inferred both from morphological criteria and sequencing of a part of the cytochrome b of the mitochondrial DNA. These taxa are closely related to Malagasy sandflies.     

Lutzomyia derelicta (Diptera: Psychodidae) a singular new phlebotomine sand fly from an Inselberg in Northeastern Amazonia.

Lutzomyia derelicta n. sp. is described from specimens collected in an isolated xeric habitat in the rainforest in the north of the State of Pará, Brazil. The new species lacks the posterior bulge in the dorsal wall of the cibarium characteristic of the New World genus Lutzomyia, and the armature of the male genitalia is of the pattern found elsewhere only in the Old World species of Sergentomyia. L. derelicta is phenetically intermediate between the known species of Lutzomyia and Sergentomyia, and cannot readily be placed in any existing subgenus or species group of either genus.     

Spauligodon aloisei n. sp. (Nematoda: Pharyngodonidae) parasite of Podarcis sicula (Reptilia: Lacertidae) from Italy

A new species of an oxyurid nematode is described from the large intestine of the lacertid lizard Podarcis sicula (Rafinesque. 1810) (Reptilia: Lacertidae) from Italy. Spauligodon aloisei n. sp. differs from other species of the genus by a combination of morphological and metrical characters, including a spined tail in males and females, absence of a spicule in males, arrangement of the last pair of the male caudal papillae, vulva location, and egg morphology. The species most similar to S. aloisei n. sp. is Spauligodon caspius Annayev, 1987, described from Tenuidactylus (=Gymnodactylus) caspius in Turkmenistan. Tail length and location of the excretory pore and vulvar opening separate S. caspius from S. aloisei n. sp. This article increases the number of species of this genus from reptiles in the Paleartic Realm to 19.     

A new species of blackflies--Simulium (Argentisimulium) dolini sp. n. (Diptera, Simuliidae)

Female, male and larva of the new species of black flies, Simulium (Argentisimulium) dolini sp. n. are described. By its morphology the species occupies an "intermediate position" between S. nolleri and S. palustre. In the USSR the species was found in wooded and forest-steppe zones of West Ukraine.

Observations on a new species of Symphyonemopsis Tiwari & Mitra,viz. S. Pantii n. sp. (Cyanophyta,Stigonematales)

The paper describes the morphology and reproduction of a new species of Symphyonemopsis viz. S. pantii n. sp. isolated from enrichment cultures of a soil sample collected from the campus of Sangeet Samiti, Allahabad (India). Thalli grow as dark blue-green, small, wooly patches on soil surface but as cushion-like growths on agar plates. It has a prostrate and erect system. The latter bears secondary branches of almost equal breadth. It possesses both false and true branches. Usually true branches are reverse V-shaped. The alga shows formation of hormocysts and akinetes. In old cultures usually the main filament becomes multiseriate. The crescent-shaped stages of hormocysts are also present here. Cells of the present alga are constricted at the cross-walls On comparison it was found to come close to Symphyonemopsis katniensis Tiwari et Mitra but differs in certain fundamental characters. It is, therefore, described as a new species viz. S. pantii n. sp. (Cyanophyta, Stigonematales, Mastigocladaceae).     

Two new species of Rhabdias (Nematoda: Rhabdiasidae) from the marine toad, Bufo marinus (L.) (Lissamphibia: Anura: Bufonidae), in Central America

Two new Rhabdias species are described from the lungs of the cane toad Bufo marinus (L.) from Costa Rica and Nicaragua. Rhabdias alabialis n. sp. differs from other known species of the genus by the remarkable morphology of its head end, i.e., the absence of lips or pseudolabia, the slitlike oral opening, and the triangular shape of the buccal capsule in apical view. Rhabdias pseudosphaerocephala n. sp. is identified as a form previously known in Central and South America as Rhabdias sphaerocephala Goodey, 1924, a species initially described from toads in Europe. The new species is differentiated from R. sphaerocephala based on head-end morphology and sequences of nuclear rDNA.     

Chabaudechina n. g. (Nematoda: Seuratidae), with the description of two new species from dasyurid marsupials from Australia

Chabaudechina presidentei n. g., n. sp. (Seuratidae: Echinonematinae) is described from Sminthopsis virginiae, S. macroura and S. youngsoni (Dasyuridae) from northern Australia. The new genus can be distinguished from all other genera of the Echinonematinae by the morphology and number of rows of cephalic hooks as well as the morphology and arrangement of body hooks and spines. The genus otherwise resembles the echinonematines in spicule morphology and arrangement of cloacal papillae. It resembles Inglechina and Linstowinema in having a triangular mouth opening, no lips and two pairs of double cephalic papillae. C. presidentei differs from C. haycocki n. sp. from Dasycercus cristicauda from central Australia in the number of caudal papillae, the proportions of the alae surrounding the cloaca and the posterior ventral cuticular spination of the male. Chabaudechina sp., found in Planigale spp., could not be identified to species level.     

<Emphasis Type="Italic">Steinernema costaricense</Emphasis> n. sp. and <Emphasis Type="Italic">S. puntauvense</Emphasis> n. sp. (Rhabditida: Steinernematidae), two new entomopathogenic nematodes from Costa Rica

Steinernema costaricense n. sp. and S. puntauvense n. sp. were recovered during a survey for native entomopathogenic nematodes in Costa Rica. Morphological data, molecular (28S rDNA sequence data) studies and cross-hybridisation tests were used for diagnostic and identification purposes. Additionally, 28S rDNA sequence data were used to assess the evolutionary relationships of the new species with other Steinernema spp. Morphological diagnostic features for S. costaricense n. sp. include: the body size of the infective juvenile (av. 1,696); the presence of protruding 'horn-like' cephalic papillae; the position of the excretory pore in the infective juvenile (av. 77 microm) and the first generation male (av. 117 microm); the D% value of the infective juvenile (av. 53) and the first generation male (av. 56); the E% value of the infective juvenile (av. 85); and the morphology of the spicules and gubernaculum of the first generation male. Diagnostic traits for S. puntauvense n. sp. are: the position of the excretory pore in the infective juveniles (av. 25 microm); the shape and size of the spicules and gubernaculum of the first generation male; and the shape of the tail of the first generation female. In addition to these traits, 28S rDNA sequences analysis and hybridisation tests showed that both new Steinernema species are distinct and unique entities.     

A new genus and four new species of felt scales on Eucalyptus (Hemiptera: Coccoidea: Eriococcidae) in south-eastern Australia

Abstract  A new Australian eriococcid genus Fragorbis gen. n. (Hemiptera: Coccoidea) is described for ' Sphaerococcus ' pustulans Green and four new species, F. fructus sp. n., F. pseudopustulans sp. n., F. stipites sp. n. and F. superfacies sp. n. Four of the five species are known only from Victoria and the fifth species from the High Country east of Tumut in New South Wales. All species feed on Eucalyptus (Myrtaceae), either in blister galls, or under or on the bark. The adult female of each species and the first-instar nymph of F. pseudopustulans sp. n. are described and illustrated. Keys are provided to the adult females of the eriococcid genera found on Eucalyptus and Corymbia , and to the species of Fragorbis gen. n.     

Argia mayi, a new species from México (Zygoptera: Coenagrionidae)

A new species of Argia is illustrated and described from material collected in the states of Colima, Guerrero, Jalisco, Michoacán, Morelos and Oaxaca, México. Argia mayi n. sp. is morphologically similar to Argia pocomana Calvert. It differs from the latter by the morphology of the abdominal appendages in the males and by having four postquadrangular cells in FW in both sexes, blue on the dorsum of males restricted to S8-9 and an erect hind margin of the mesostigmal plate in females.     

Skrjabinelazia rizzoi n. sp. (Nematoda: Seuratoidea) from a Sicilian lacertid, with comments on specific and biological diversity in the genus

Skrjabinelazia rizzoi n. sp. (Seuratoidea), from Podarcis sicula captured at Cammarata, Agrigento Province, Sicily, is distinct from the 13 known species of the genus, including Skrjabinelazio sp. Rizzo from Catania. It is identified with the following set of characters: in the male, short spicules and gubernaculum, thin body; in the female, buccal cavity with a crown of leaflets, body cuticle without internal ornamentation, presence of cephalic and caudal vesicles, tail with a terminal digitiform spike 42-48 microm long. The morphology of the new species supports our previous hypothesis of two Skrjabinelazia lineages, one with spicules and one without spicules, respectively linked to Lacertidae and Gekkonidae. In Palearctic lacertids, five named species are presently known, S. taurica from Crimea (Ukraine), S. hoffmanni from Beijing (China), S. pyrenaica from Pyrenees (Spain), S. vozae from Cevennes (France), S. rizzoi from Agrigento Province, Sicily (Italy), but analysis of some published works suggests a greater diversity. S. rizzoi infection, found in April-May in 1/5 lizards, was recent with young females in the host's stomach and intestine, and males in the stomach. One female contained four membranous-shelled eggs. The two other females contained a few hatched infective larvae, membranous-shelled eggs with developing embryos and, unexpectedly at this early stage, a few thick-shelled divided eggs. As in several other Skrjabinelazia species, the progeny of S. rizzoi are adapted for intra-host suprainfection and inter-host transmission, but in this species the production of resistant eggs appears in very young females.     

A STUDY OF PHLEBOTOMINE SANDFLIES IN YUNAN PROVINCE lV. SERGENTOMYIA (NEOPHLEBOTOMVS) WEEH. M SP. NOV. (DIPTERA: PSYCHODIDAE)

Abstract In August 5–14, 1989 the authors collected many phlebotomine sandflies in natural lime-stone caves from Yiwu and Mengyuan, Xishuangbanna, Yunnan Province. Among them 10 species of phle-botomines were found, i.e., Idiophlebotomus longiforceps, Phlebotomus yunshpis, P. trunmcsis, P. kiangsuensis, P. stantoni, Serptomyia rudnicki, S. barraudi, S. iyngari, S. koloshanensis , and S. bailyi (He and Leng 1991). Additionally a new species of the subgenus Neophlebotomus is described as Sergentomyia (Neophlebotomus) kueichenae in honour of Professor Kueichen Li.     

Revision of the Nearctic species of the genus Stiropius Cameron (=Bucculatriplex Auct.) with the description of a new related genus (Hymenoptera: Braconidae)

Abstract. The New World rogadine genus Stiropius Cameron is revised for the Nearctic region and a new related genus from the Americas, Viridipyge , is decribed. Bucculatriplex Viereck is found to be a junior subjective synonym of Stiropius Cameron. Three Nearctic species are recognized: S.bucculatricis (Ashmead) comb.n., S.californicus sp.n. and S.wagneri sp.n. A single Nearctic specis of Viridipyge is described as new: V.prunicola , and a Neotropical species, V.letifer (Mann) comb.n., is found to be congeneric. The biology and systematic relationships of both genera are discussed; the two genera appear to represent a relatively basal branch of the Rogadini lineage.     

Siteroptes (Siteroptoides) species with Pediculaster-like phoretomorphs (Acari: Tarsonemida: Pygmephoridae) from New Zealand and Polynesia

Abstract

Six species of Siteroptes subgenus Siteroptoides—kneeboni (Wicht), mesembrinae (Canestrini), microsaniae n.sp., morelliae (Rack), muscarius n.sp., and portatus n.sp.—have been found in New Zealand. S. (S.) mesembrinae occurs on Niue Island also, and a further new species, pacificus, is recorded from Tonga. The phoretomorph females of all 7 species, the normal females of 4, the males of 3, and larvae of 2 are described and compared. The similarities and differences between normal and phoretomorph females are particularly noted. Besides kneeboni, 2 species described by Wicht but not occuring in New Zealand—athiasae and flechtmanni— are redescribed from type material and transferred to Siteroptes (Siteroptoides). Keys are given for normal females and Pediculaster-like phoretomorph females of Siteroptoides. Siteroptes mesembrinae subsimilis and S. ignotus altaicus are raised to species status. Diagnostically important measurements are given to help define the variation within and between species and morphs.     

Morphological and molecular data of new species of Characithecium and Diaphorocleidus (Monogenea: Dactylogyridae) from Neotropical characid fishes

The present study describes three new species of monogenean parasites of characid fishes from the Upper Paraná River basin, Brazil: Characithecium paranapanemense n. sp. on Psalidodon paranae and Psalidodon bockmanni, Diaphorocleidus magnus n. sp. on Astyanax lacustris and Psalidodon fasciatus, and Diaphorocleidus neotropicalis n. sp. on Astyanax lacustris and P. bockmanni. An amendment for Diaphorocleidus is proposed, since additional characters observed in the new species required to extend the generic diagnostic features mainly to include: articulation process connecting the base of the MCO with accessory piece present or absent, and accessory piece with variable shapes (plate-like, pincer-shaped, wrench-shaped, sheath-shaped), divided or not into subunits. Characithecium paranapanemense n. sp. can be distinguished from other congeners by the morphology of its MCO and accessory piece. Diaphorocleidus magnus n. sp. differs from most of its congeners by the morphology of its accessory piece, the presence of articulation process connecting the base of the MCO with accessory piece, and the morphology of the sclerotized structures of the haptor. Diaphorocleidus neotropicalis n. sp. can be easily distinguished from its congeners by the morphology of the accessory piece, the sclerotized structures of the haptor and the morphology of the vagina. Molecular data of the new species (partial 28S rDNA and mitochondrial cytochrome oxidase I) were obtained and the first phylogenetic analysis based on 28S rDNA gene sequences for species of Characithecium and Diaphorocleidus are provided. Although Diaphorocleidus and Characithecium share some morphological similarities, phylogenetic analysis indicates that species of these two genera are not closely related.     

Six new cavernicolous cixiid planthoppers in the genus Solonaima from Australia (Homoptera: Fulgoroidea)

Abstract The monophyletic genus Solonaima , endemic to northern Queensland, is reviewed and six new species are described: S.sullivani sp.n., S.pholetor sp.n., S.stonei sp.n., S.halos sp.n., S.irvini sp.n. and S. baylissa sp.n. The previously known epigean species, S.solonaima Kirkaldy and S.pallesens (Distant) are illustrated and redescribed. The six new species represent four separate independent cave invasions and nearly double the number of known cavernicolous cixiids in the world. This is the first report of a closely related group of cave-dwelling Homoptera showing varying degrees of cave adaptation. One facultative cave species, S.sullivani , shows virtually no modification from surface relatives. Two species, S.pholetor and S.stonei , show some eye, colour, and wing-reduction, but they are still flighted and are considered facultative cave species. S.halos and S. irvini are nearly blind and have reduced, non-functional wings and are considered obligate cave species. S. baylissa , the most remarkable obligate cave species, is highly modified: eyeless, nearly wingless and colourless. The evolutionary trends displayed in cave adaptation are illustrated and discussed. These include reduction in body colour, eyes and wings, alteration of head and thorax shape, and possibly simplification of the male genitalia. The geology of the caves is complex and ranges from greater than 5-million-year-old caves in Silurian-aged metamorphosed limestone to 190,000-year-old lava tubes. The facultative species are generally found in the most open caves, the two intermediate obligate species are found in deeper caves, and the most highly modified species is restricted to damp cave passages with high CO₂ levels. There is no correlation between the ages of the caves and the degree of cave adaptation.
