Description of three new species of Paractenopsyllus genus (Siphonaptera: Leptopsyllinae) from Madagascar

The males of three new and rare species of the Malagasy endemic genus Paractenopsyllus Wagner, 1938 are described. Paractenopsyllus beaucournui, P. oconnori and P. raxworthyi have been collected on endemic small mammals and the black rat. As for others species of the genus, biotopes are rain-forests of the central highlands or the northern mountains of Madagascar. Two of the described species were collected at elevations lower than typical for the genus and below the limits of the highland bioclimatic zone. Morphological affinities between these new species and those already described provide taxonomic framework for the genus. An updated identification key is provided for the diagnosis of all the 20 Malagasy species of Leptopsyllinae.     

Description of Deviata rositae n. sp., a new ciliate species (Ciliophora, Stichotrichia) from Argentina

Soil samples were taken from a temporary pond located in Buenos Aires province, Argentina, during the dry phase in the summer of 2005. The ciliates were studied alive and after staining with protargol. Deviata rositae n. sp. measures 112-154 microm in length and 21-28 microm in width in vivo and has a vermiform body. The contractile vacuole is located in the mid-body on the left. The macronucleus is moniliform and there are 1-3 micronuclei. The oral apparatus is composed of 14-18 adoral membranelles and straight paroral and endoral membranes that never intersect each other. The somatic ciliature is arranged in four frontal cirri, one buccal cirrus, six long and slightly spiraled rows of cirri with the first right row extending up to the equatorial or sub-equatorial region, and two dorsal rows of dikinetids. This new species of Deviata primarily differs from its congeners by the number of macronuclear nodules and the number and disposition of the dorsal rows of dikinetids.     

Two new species of fleas from Chile and Argentina(Insecta-Siphonaptera: Stephanocircidae and Rhopalopsyllidae) and raising of a new sub-genus of Plocopsylla Jordan, 1931

A new subgenus of Plocopsylla is raised, Schrammapsylla Beaucournu and Ménier from the entire group B of Schramm & Lewis, 1988 and two new fleas from Chile and Argentina are described: Plocopsylla (S.) muruai n. sp. Beaucournu and Gallardo and Ectinorus (E.) mimacydis n. sp. Beaucournu and Gallardo. These two taxa are only known by the male sex.     

Description of a new species of the subgenus Hirtodrosophila (Drosophila: Drosophilidae: Diptera: Insecta) from Chandigarh, India

A new species belonging to the subgenus Hirtodrosophila of the genus Drosophila is described from Chandigarh, India. The relationship, based on the morphology, periphallic organs and phallic organs, at the subgeneric and generic levels is discussed in detail. This new species does not resemble, in external morphology, any of the species described so far. However, in the structures of periphallic and phallic organs it resembles to D. (H.) nokogiri Okada (1956) and D. (H.) histiroides Okada & Kurokawa (1957). The present species is characterized by the presence of a pair of paired black stripes separated by a silvery-white stripe on the mesonotum and scutellum.     

A new flea of the genus Ctenidiosomus (Siphonaptera,Pygiopsyllidae) from Salta Province,Argentina

A new species of flea of the genus Ctenidiosomus Jordan, 1931 (Siphonaptera: Pygiopsyllidae) is described from Phyllotis osilae J. A. Allen, 1901, from Salta Province, Argentina. This is the first time that Ctenidiosomus has been recorded in Argentina. A key to species of males of Ctenidiosomus is presented.     

Description of two new species of the leafhopper subgenus Pediopsoides (Pediopsoides) (Hemiptera,Cicadellidae, Macropsinae) from Guangxi Province,Southern China

Two new species of the Macropsinae leafhopper subgenus Pediopsoides (Pediopsoides) Matsumura, 1912, Pediopsoides (Pediopsoides) damingshanensis Li, Dai & Li, sp. n. and Pediopsoides (Pediopsoides) tishetshkini Li, Dai & Li sp. n., are described and illustrated from Guangxi Province of southern China. A key to males is provided to distinguish the species of the subgenus along with a map showing the distribution of the new species.

Description of Pintomyia salomoni sp. n., a new phlebotomine species from northwest Argentina

A new species of phlebotomine sandfly is described and illustrated using male and female specimens collected in the provinces of Jujuy and Tucumán, Argentina. Both male and female morphological characters allow the inclusion of the new species within the Pintomyia genus, Pifanomyia subgenus, serrana series (Diptera: Psychodidae). The species was denominated as Pintomyia salomoni n. sp., and is closely related to Pintomyia (Pifanomyia) torresi and Pintomyia (Piffanomyia) boliviana.

A new species and a new record of Nycteridopsylla Oudemans, 1906 (Siphonaptera: Ischnopsyllidae) from China

A new species, Nycteridopsylla quadrispina, found on the vespertilionid bat Ia io, is described from China. N. iae Beaucournu & Kock, 1992, a new record for China, was also found on the same host. The new species is distinguished by the presence of four spines on the genal comb and by the shape and chaetotaxy of the head.

Description of a new Pratylenchus species from China(Tylenchida,Pratylenchidae)

Pratylenchus ekrami from maize(Zea mays) roots in Shenyang and luffa(Luffa cylindrica) roots in Dalian, China, are described in this paper. Nematodes from the two areas were identified consistently, and were characterized by a heavy cephalic sclerotization, extending posteriorly up to two body annuli, stylet 11 13 μm long, elongating conoid tail, and becoming thinner from vulva. Males were not found. Pratylenchus ekrami is close to Pratylenchus vulnus, but the most critical characteristics between the two species were the number of lip annuli, stylet size, and shape of stylet knobs. This species is the first reported in China.     

Anopheles halophylus,a new species of the subgenus Nyssorhynchus (Diptera: Culicidae) from Brazil
