Leptopsyllines from Madagascar (Insecta: Siphonaptera: Ceratophyllidae): description of five new species of Paractenopsyllus Wagner, 1938

Five new species of the malagasy endemic genus Paractenopsyllus Wagner, 1938, are described. Paractenopsyllus rouxi, P. ratovonjatoi, P. duplantieri, P. juliamarinus and P. gemelli have been collected on endemic small mammals and the black rat. Biotopes are mid-elevation rain-forests of the central highlands or the northern mountains of Madagascar. Morphological affinities between these new species and those already known provide taxonomic links within the genus. Differences in the spatial and altitudinal distributions and host ranges allow discussion of the potential factors important in the species distribution of this genus.     

Humicolous microcharmid scorpions: a new genus and species from Madagascar

A new genus and species of humicolous microcharmid scorpion are described on the basis of a single specimen collected in the Ankarana Reserve, Madagascar. New considerations regarding the taxonomy and morphology of micro-buthoid Malagasy scorpions are proposed, based mainly on the study of the peg-shaped sensillae of the pectines by scanning electron microscopy.     

One new genus and three new species of Orsillinae (Hemiptera: Lygaeidae) from Australia

Abstract  Two new species of Nysius Dallas, N. orarius sp. n. and N. tasmaniensis sp. n. are described from New South Wales and Tasmania (Australia), respectively. A new monotypic genus, Reticulatonysius , with type-species R. queenslandensis sp. n. is described from Queensland, and its systematic relationship with other orsilline genera is discussed.

A new species of flea in the genus Ctenophthalmus (Siphonaptera: Hystrichopsyllidae)]

A new species, Ctenophthalmus (Euctenophthalmus) parthicus sp. n., is described from social vole (Microtus socialis Pallas) from four localities of the West Kopetdag Mountains of Turkmenia. The new species is close to C.(E.) secundus Wagner and C.(E.) congener nadimi Farhang-Azad. It differs from males of the other known species by the following characters. The movable process has an infra-acetabular process whose length is the same as the height of its supra-acetabular portion. The movable process has the straight front margin, right anterior apical angle. The anterior part of the dorsal margin of the movable process is elevated, the hind part is slightly concave. The posterior apical angle of the movable process is cut. The hind margin of the movable process is convex. The apex of the distal arm of sternum IX is straight, not oblique. The female differs by the following peculiarities. Sternum VII has a well developed dorsal lobe below which there is a smaller rounded lobe and a distinct small ventral process. Unciform sclerotization of tergum VIII (or the place of connection between tergum VIII and its internal lobe) resembles an arc. The front margin of the internal lobe of tergum VIII is not sclerotized. The bursa copulatrix is as long as the dorsal spines of pronotum.     

The flea genus Sigmactenus (Siphonaptera: Leptopsyllidae): a new species from timor and new material from New Guinea and the Philippines

Both sexes of Sigmactenus timorensis n. sp. are described from Rattus tanezumi and Rattus exulans collected in West Timor, Indonesia. The true host presumably is a native murine rat such as the extant, endemic Rattus timorensis or 1 of several extinct, endemic Timorese rats. Analyses of new collections of Sigmactenus cavifrons and Sigmactenus toxopeusi from New Guinea demonstrate that these fleas show considerable morphological variation. We propose that they represent a single species with the name S. toxopeusi having priority. New collections of Sigmactenus werneri from the Philippines expand the known hosts and geographical distribution of this flea.     

Description of three new species of Ixodes Latreille, 1795 (Acari: Ixodidae), parasites of tenrecs (Afrotheria: Tenrecidae) on Madagascar

Ixodes soarimalalae n. sp., Ixodes uilenbergi n. sp. and Ixodes uncus n. sp. (Acari: Ixodidae), are described based on females ex various species of tenrecs (Afrosoricida: Tenrecidae) from Madagascar. Females of all of these new species are similar to those of other species of the subgenus Afrixodes Morel, 1966 known from Madagascar, from which they can be distinguished and from one other by the size of scutum, size of scutal setae, shape of alloscutal setae, shape of genital aperture, development of genital apron, size of auriculae, size of anterior angle of basis capituli, size of palpi, dental formula on hypostome and size and development of spurs on coxa I.

     

Three new species of the genus Medwayella Traub, 1972 (Insecta: Siphonaptera: Pygiopsyllidae) from Sabah (eastern Malaysia, Borneo)

Medwayella traubiana n. sp., M. pfeifferi n. sp. and M. sabahae n. sp. (Pygiopsyllidae) are described from Sabah (north of Borneo island), the first two on Tupaia tana (Scandentia), the last on Sundasciurus lowii (Rodentia). Sex male is only identified, because these fleas have been collected in sympatry, or even in syntopy. Their determination is based on segment IX and aedeagus. If M. traubiana and M. pfeifferi are related to some known species, M. sabahae is clearly distinct from other Medwayella.     

A new genus and three new species of decapodiform cephalopods (Mollusca: Cephalopoda)

We describe here two new species of oegopsid squids. The first is an Asperoteuthis (Chiroteuthidae), and it is based on 18 specimens. This new species has sucker dentition and a funnel–mantle locking apparatus that are unique within the genus. The second new species is a Promachoteuthis (Promachoteuthidae), and is based on a unique specimen. This new species has tentacle ornamentation which is unique within the genus. We also describe a new genus and a new species of sepioid squid in the subfamily Heteroteuthinae (Sepiolidae) and it is based on four specimens. This new genus and species exhibits unique modifications of the arms in males.     

Two new species of coccidia (Apicomplexa: Eimeriidae) from Madagascar Gekkonids

Two new species of coccidia (Apicomplexa: Eimeriidae) are described from the Madagascar giant day gecko, Phelsuma madagascariensis grandis, and the Golddust day gecko, P. laticauda. Both species of coccidia were found to infect the anterior one-half of the small intestine. Oocysts of Eimeria brygooi n. sp. are spherical or subspherical, 23.0 X 21.3 (18.8-25.2 X 16.4-23.2)micron; shape index (L/W) 1.1 (1.0-1.2). A micropyle, oocyst residuum, and polar granule are absent. Sporocysts are ovoid, 9.2 X 7.9 (8.0-10.0 X 7.2-8.8) micron; shape index 1.2 (1.0-1.3), with a Goussia-type suture; Stieda and substieda bodies are absent. A sporocyst residuum is present, 4.2 X 3.0 (3.2-6.4 X 2.4-4.0) micron. Sporozoites are elongate, with anterior and posterior refractile bodies. This coccidian was found to infect five of six (83%) P. m. grandis and one of five (20%) P. laticauda examined. Oocysts of Isospora gekkonis n. sp. are spherical or subspherical, 24.2 X 22.0 (21.6-26.4 X 20.0-23.6) micron; shape index 1.1 (1.0-1.2). A micropyle and oocyst residuum are absent; polar granule present. Sporocysts are ovoid, 12.2 X 9.4 (11.2-12.8 X 8.4-10.0) micron, with Stieda and substieda bodies; shape index 1.3 (1.2-1.4). A sporocyst residuum is present, either compact, 5.1 X 4.2 (4.0-7.2 X 3.2-5.6) micron or diffuse. Sporozoites are elongate, with anterior and posterior refractile bodies. Isospora gekkonis was found in two of six (33%) P. m. grandis and one of five (20%) P. laticauda. In addition, oocysts of Cryptosporidium sp. were found in the cloacas of two of six (33%) necropsied P. m. grandis.
