Haematozoa in Domestic Chickens and Guinea Fowl in Tanzania and Transmission of Leucocytozoon neavei and Leucocytozoon schoutedeni

SYNOPSIS. Leucocytozoon neavei and Leucocytozoon caulleryi were found in guinea fowl in Tanzania and Leucocytozoon schoutedeni in chickens. The minimum time required for sporogony of L. neavei at approximately 20 C was ∼7 days in Simulium adersi and Simulium nyasalandicum. Gametocytes of L. neavei , which appeared mature, were seen in the peripheral blood of guinea fowl chicks 14 days after experimenal inoculation with sporozoites from S. adersi or S. nyasalandicum. Sporogony of L. schoutedeni was followed in "Simulium impukane," S. adersi, Simulium vorax and S. nyasalandicum. Oocysts were ∼12 μm in diameter. Sporogony of some individuals was completed in 6–7 days at 20 C. Each oocyst produced ∼50–60 sporozoites. Gametocytes were detected in the peripheral blood of a chicken 10–14 days after experimental inoculation with sporozoites of L. schoutedeni from S. adersi and "S. impukane."

陕西省蚋属一新种记述(双翅目:蚋科)

Simulium (Simulium) liubaense, sp. nov. is described based on the female specimens collected from Liuba, Shaanxi Province, China. This species is assigned to the variegotum-group of the subgenus Simulium, and is closely related to S. (S.) jingfui Cai and An, 2008, S. (S.) taiwanicum Takaoka, 1979, S. (S.) hackeri Edwards 1928, S. (S.) chamlongi Takaoka and Suzuki, 1984. However it is clearly differentiated from them by the structure of cibarium, genital fork, genital plate, paraproct and cercus of the female. All the specimens are kept in the Medical Entomology Collection Gallery, Academy of Military Medical Sciences, Beijing.

Revision of the Ketaketa subcomplex of blackflies of the Simulium damnosum complex

A revision of the taxonomy of the Ketaketa subcomplex of the Simulium damnosum Theobald complex (Diptera: Simuliidae) is presented including new material from Tanzania, Malawi and South Africa. The cytotaxonomy, morphology and molecular identity of known and new taxa are described. The Ketaketa subcomplex is cytotaxonomically defined by the paracentric inversion 1L-7. We recognize three sibling species, namely Simulium latipollex (Enderlein), Simulium plumbeum Krueger, sp.n. and Simulium kipengere Krueger, sp.n., the latter comprising three cytoforms: 'Typical', 'Linthipe' and 'Mombo'. The cytoforms 'Mwamphanzi', 'Ketaketa' and 'Hammerkopi' are synonymized with S. plumbeum. Identification keys are provided on the basis of chromosomal and morphological characters. In view of their potential role as vectors of human onchocerciasis (river blindness) we also discuss the possible medical importance of the different cytoforms and their geographical distribution.

The Simulium vernum group (Diptera: Simuliidae) in Europe: multiple character sets for assessing species status

The value of using characters from multiple sources – chromosomes, ecology, gene sequences, and morphology – to evaluate the species status of closely related black flies is demonstrated for three European members of the Simulium vernum group: Simulium crenobium (Knoz, 1961), Simulium juxtacrenobium Bass & Brockhouse, 1990, and Simulium vernum s.s. Macquart, 1826. Simulium juxtacrenobium is a chromosomally, molecularly, and morphologically distinct species that diverged from S. crenobium and S. vernum s.s. about 2 Mya. It is specialized for intermittent streams, is univoltine, and is recorded for the first time from northern Europe, based on collections from Finland and Sweden, representing a range extension of about 1800 km. In contrast, S. crenobium, although confirmed as a distinct species, differs from S. vernum s.s. by only a few larval and chromosomal characters, and by a breeding habitat restricted to mountain spring brooks. Whereas all four character sets independently support the specific distinctness of S. juxtacrenobium and S. vernum s.s., multiple character sets are required to establish the specific validity of S. crenobium.
