Neottialges (Pelecanectes) ibisicola sp. n. (Acari: Hypoderidae) from the subcutaneous tissues of the white-faced ibis, Plegadis chihi (Ciconiiformes: Threskiornithidae)

Neottialges (Pelecanectes) ibisicola sp. n. is described from the subcutaneous tissues of the White-faced Ibis, Plegadis chihi, from west Texas. The new species is similar to N. (P.) plegadicola Fain, but differs from this and other species of the subgenus by idiosomal chaetotaxy, presence of a bifurcate apical extension on Tarsus III, solenidion phi on Tibia I less than 1/2 as long in the new species, lateroventral seta of Tibia I whiplike, structure of the genital sclerite and suckers, and presence of punctations on the dorsal idiosoma. The morphology and host-parasite relationships of the new species are compared with those of related species of hypopi from the host family Threskiornithidae.     

Taxonomy of the Neotropical Genus Americabaetis,New Status (Insecta: Ephemeroptera: Baetidae)

Americabaetis (Insecta: Ephemeroptera: Baetidae), previously considered synonymous with Acerpenna, is reinstated and given generic rank. The genus differs from Acerpenna in lacking hindwings, gills on abdominal segment 1, and a conical process between the male genital forceps, and in possessing apically rounded gills on abdominal segment 7. The genus has a general Neotropical distribution with a northern limit in east-central Mexico. Five new species of Americabaetis are described from South America: A. alphus, new species, from Argentina, Bolivia, Brazil, Chile, and Paraguay; A. labiosus, new species, from Brazil, Paraguay, and Uruguay; A. longetron, new species, from Brazil, Paraguay, and Uruguay; A. maxifolium, new species, from Paraguay; and A. titthion, new species, from Brazil. Americabaetis boriquensis, new combination; A. intermedius, new combination; A. naranjoi, new combination; A. pleturus, new combination; and A. robacki, new combination, are reviewed.     

A New Species of the Genus Tylototriton(Amphibia: Urodela: Salamandridae) from Eastern Himalaya

A new species of the genus Tylototriton is described from eastern Himalaya based on molecular and morphological comparisons. The new species is diagnosable from the closely-related species by having light brown colouration in dorsal region in life, flat and blunt snout, greatly separated dorsolateral bony ridges on head and straightthick tailfin. In addition to head morphology, the new species is also morphologically distinguishable from its closelyrelated species Tylototriton shanorum by having 16 dorsal warts and average smaller Snout Vent Length(SVL).     

Host-parasite associations of Eimeria spp. (Apicomplexa:Eimeriidae) in kangaroos and wallabies of the genus Macropus (Marsupialia:Macropodidae)

Faecal samples from 514 kangaroos and wallabies representing 12 species of the genus Macropus were examined for oocysts of Eimeria spp. Six species of Eimeria were redescribed from their type hosts, and on the basis of finding homologous oocysts in the faeces of other Macropus spp., host ranges for these coccidia were extended. Eimeria hestermani Mykytowycz, 1964 is redescribed from M. giganteus (eastern grey kangaroo) and is described from M. fuliginosus (western grey kangaroo), M. rufogriseus (red-necked wallaby), M. dorsalis (black-striped wallaby), and M. eugenii (tammar wallaby). E. toganmainensis Mykytowycz, 1964 is redescribed from M. rufus (red kangaroo) and the host range is extended to M. giganteus, M. fuliginosus, M. rufogriseus and M. eugenii. E. wilcanniensis Mykytowycz, 1964 is redescribed from M. rufus, and the host range is extended to M. giganteus, M. fuliginosus and M. robustus (euro or wallaroo). E. macropodis Wenyon & Scott, 1925 is redescribed from M. rufogriseus, and is described from M. giganteus, M. fuliginosus, M. rufus, M. irma (western brush wallaby), M. parryi (whip-tailed wallaby), M. dorsalis, M. eugenii, and M. parma (parma wallaby). E. fausti Yakimoff & Matschoulsky, 1936, E. cunnamullensis Mykytowycz, 1964 and E. purchasei Mykytowycz, 1964 are synonymized with E. macropodis. E. marsupialium Yakimoff & Matschoulsky, 1936 is redescribed from M. giganteus, and from M. fuliginosus. E. gungahlinensis Mykytowycz, 1964 is redescribed from M. fuliginosus, and from M. giganteus. Seven new species of Eimeria are described. E. flindersi, new species, is described from M. eugenii, M. rufogriseus, and M. antilopinus (antilopine wallaroo). E. prionotemni, new species, is described from M. eugenii, M. parryi, M. rufogriseus, M. agilis (agile wallaby) and M. dorsalis. E. mykytowyczi, new species, is described from M. agilis, M. antilopinus, and M. parryi. E. parryi, new species, is described from M. parryi. E. yathongensis, new species, is described from M. fuliginosus and M. giganteus. E. parma, new species, is described from M. parma, and E. desmaresti, new species, is described from M. rufogriseus. E. kogoni Mykytowycz, 1964, and E. rufusi Prasad, 1960 are considered species inquirendae. The host-parasite associations of these coccidia, and of similar species of Eimeria in other genera of Macropodoid marsupials, are discussed in relation to the postulated phylogeny of the hosts.     

Australian species of Sinella (Sinella) Brook (Collembola: Entomobryidae)

Abstract  The Australian subgenus Sinella ( Sinella ) Brook is revised. Two species are recognised. A new species from New South Wales and South Australia, Sinella ( Sinella ) samueli , is described and the widely distributed species Sinella ( Sinella ) termitum Schött is redescribed based on examination of a specimen from the type series and fresh collections from a wide range of localities in south-eastern Australia. New patterns of chaetotaxy for the genus are described from these species.     

A new species of Spauligodon (Nematoda: Oxyuroidea: Pharyngodonidae) in Latastia longicaudata (Sauria: Lacertidae) from Kenya

A new species of Spauligodon , Spauligodon latasticola n. sp., from the intestines of Latastia longicaudata (Lacertidae) from Kenya is described and illustrated. Spauligodon latasticola represents the 47th species assigned to the genus and the 8th species from the Ethiopian region. The new species differs from all but 2 other species assigned to Spauligodon by the presence of a conically tapering tail in the female. The new species is separated from the 2 similar species, Spauligodon garciaprietoi and Spauligodon goldbergi, by the position of the vulva, which is anterior to the esophageal bulb in the new species, at the level of the esophageal bulb in S. goldbergi, and posterior to the esophageal bulb in S. garciaprietoi.     

Revision of the Protohermes changningensis species group from China (Megaloptera: Corydalidae: Corydalinae)

A new species group, the Protohermes changningensis group, of the dobsonfly genus Protohermes is established. Three species belonging to the new species group from China are described and illustrated, including one new species. Phylogenetic relationships among the species in this group and biogeography are discussed on the basis of a cladistic analysis using Hennig 86.     

Helminths of Pholidobolus montium (Sauria: Gymnophthalmidae) from Ecuador with description of a new species of Skrjabinodon (Nematoda: Oxyuroidea: Pharyngodonidae)

Skrjabinodon aspercaudus n. sp. from the large intestine of Pholidobolus montium (Gymnophthalmidae) from Ecuador is described and illustrated. Skrjabinodon aspercaudus represents the 29th species assigned to the genus and the 6th species from the neotropical region. The new species differs from all other species assigned to Skrjabinodon by the presence of small bosses on the surface of the tail filament of both males and females. In addition to the new species, P. montium harbored the cestode, Cairaella henrii, and third-stage larvae of a species of Physaloptera.     

Two new species of the genus Tyrophagus (Acari: Acaridae)

Two new species of Tyrophagus Oudemans, 1924, are described. One species, T. Savasi , has been discovered in several habitats of economic importance. It closely resembles T putrescentiae (Schrank) and T. neiswander Johnston & Bruce. The second, T. rebertsonae , has so far been discovered in only two, soil and tree bark. It differs from other species of Tyrophagus by a number of character. Both new species have pigmented 'eyespots' on the prodorsal shield. A new character used to differentiate these species is the shape of the sclerotized neck of receptaculum semins.
The position of the new species in three commonly used keys to adults of the genus Tyrophagus is indicated     

Mayflies of the Northern Levant (Insecta: Ephemeroptera)

Abstract

For 31 species of mayflies, new records on their distribution are presented. Most of them are new to the Middle East or to the northern Levant (Turkey, Syria, Lebanon). The fauna is composed for the most part of species widespread in Europe (63%), a relatively high number (26%) of endemic species, and a few Caucasian (8%) and South European (3%) species. Using the genus Prosopistoma as an example, it is shown that the mayfly fauna of the northern Levantine has been isolated from the faunas of Africa and Asia for a very long period.     

Description of a new species of Kurilonema (Nematoda: Rhabdiasidae) from lungs of the skink Sphenomorphus abdictus aquilonius (Reptilia: Squamata: Scincidae) in the Philippines

Kurilonema browni n. sp. is described on the basis of specimens found in the lungs of the scincid lizard Sphenomorphus abdictus aquilonius from Aurora Province, Luzon Island, Philippines. The new species differs from Kurilonema markovi, the only previously known species in the genus, by the presence of 2 prominent lateral pseudolabia, larger body size, shorter tail length relative to total body length, and more numerous eggs in the uteri, containing fully developed larvae. The inner surface of the buccal capsule in the new species is densely covered with rounded scales that have not been observed in K. markovi or any other rhabdiasid species. This is the first record of the genus from the Philippines.     

Ectoparasitic insects (Diptera: Streblidae and Siphonaptera: Ischnopsyllidae) of bats from Iquitos and surrounding areas (Loreto, Peru)

Based on specimens collected from bats of different families, we add new species and extend the known ecological distribution and host associations of insect ectoparasites of bats in Peru. New information is provided for the distribution of 26 species of parasites (25 Diptera and 1 Siphonaptera: Ischnopsyllidae). Four species (Neotrichobius ectophyllae, Strebla galindoi, Strebla paramirabilis and Myodopsylla wolffsohni wolffsohni) are new for Peru and 16 represent new records for the department of Loreto. Also, we found 17 new host-ectoparasite relationships. Of note, we found remarkable new association between Neotrichobius delicatus and bat species from the families Molossidae and Noctilionidae and a novel association between Paradyschiria parvula and a species of Vespertilionidae. Host-ectoparasite specificity was recorded with 14 species as monoxenous, three oligoxenous, seven pleioxenous and two polyxenous.     

Description of a new species of Thynnascaris Dollfus, 1933 (Nematoda: Anisakidae) from the stomach of the marine teleost fish Rachycentron canadus (Linnaeus)

A new species of the nematode genus Thynnascaris obtained from the teleost Rachycentron canadus (Linnaeus) is reported. A detailed examination of this specimen has allowed us to erect a new species Thynnascaris to accommodate the worm. It shows remarkable differences from other known species of Thynnascaris in respect of body size, length of the oesophageal appendix and intestinal caecum, location of nerve ring and excretory pore, on the papillae on the lips arrangement, type of the striations on the cuticle, vulva position, arrangement of caudal papillae and size of the spicules. The new species is designated as Thynnascaris shyamasundarii.     

Description of Pintomyia (Pifanomyia) brazilorum sp. nov. a new fossil species from the Dominican Republic (Diptera: Psychodidae: Phlebotominae)

A sand fly fossil was found in amber; a vegetal resin, which allows all the external phlebotomine structures to be seen. The piece that contains the new species is 14 mm long x 8 mm wide x 3 mm high. All the structures from the head, thorax, and abdomen were examined under the microscope and measured with a calibrated micrometric eyepiece. The morphological aspects of the new species suggest its inclusion in the Pintomyia genus, Pifanomyia subgenus though it is not possible to include it in any of the series known for this subgenus. The presence of two atrophied spines on the gonostyles and gonocoxites without tufts of setae permit the exclusion of the new species from the other species of the subgenus Pifanomyia. The new species is named Pintomyia (Pifanomyia) brazilorum sp. nov.     

Cryptosporidium fayeri n. sp. (Apicomplexa: Cryptosporidiidae) from the Red Kangaroo (Macropus rufus)

The morphology and infectivity of the oocysts of a new species of Cryptosporidium from the faeces of the red kangaroo (Macropus rufus) are described. Oocysts are structurally indistinguishable from those of Cryptosporidium parvum. Oocysts of the new species are passed fully sporulated, lack sporocysts, and measure 4.5-5.1 microm (mean=4.9) x 3.8-5.0 microm (mean=4.3 microm) with a length to width ratio 1.02:1.18 (mean 1.14) (n=50). Oocysts were not infectious for neonate ARC Swiss mice. Multi-locus analysis of numerous unlinked loci demonstrated this species to be distinct (90.64%-97.88% similarity) from C. parvum. Based on biological and molecular data, this Cryptosporidium infecting marsupials is proposed to be a new species Cryptosporidium fayeri n. sp.     

Systematics of the Protohermes xanthodes species-group in eastern Asia (Megaloptera: Corydalidae)

A new species‐group of the dobsonfly genus Protohermes is proposed, the Protohermes xanthodes species‐group. Three species from eastern Asia belonging to the new species‐group are redescribed and illustrated. Phylogenetic relationships among the species in this group, as well as the biogeography of these species, are discussed on the basis of a cladistic analysis.
