RESUMO

The present study is based on galumnid mites (Oribatida, Galumnidae) collected from leaf litter of two mixed forests in Cuba; six species from three genera are identified. Three new species-Pergalumna (Pergalumna) cienfuegosensis sp. nov., P. (P.) foveolatostriata sp. nov. and Galumna (G.) gigantea sp. nov.-are described. Allogalumna brevisetosa (Bayartogtokh & Weigmann, 2005) is recorded in the Neotropical region for the first time; P. (P.) obvia (Berlese, 1914) is recorded in Cuba for the first time.

RESUMO

BACKGROUND: Despite the increasingly recognized eco-epidemiological significance of bats, data from molecular analyses of vector-borne bacteria in bat ectoparasites are lacking from several regions of the Old and New Worlds. METHODS: During this study, six species of ticks (630 specimens) were collected from bats in Hungary, Romania, Italy, Kenya, South Africa, China, Vietnam and Mexico. DNA was extracted from these ticks and analyzed for vector-borne bacteria with real-time PCRs (screening), as well as conventional PCRs and sequencing (for pathogen identification), based on the amplification of various genetic markers. RESULTS: In the screening assays, Rickettsia DNA was only detected in bat soft ticks, whereas Anaplasma phagocytophilum and haemoplasma DNA were present exclusively in hard ticks. Bartonella DNA was significantly more frequently amplified from hard ticks than from soft ticks of bats. In addition to Rickettsia helvetica detected by a species-specific PCR, sequencing identified four Rickettsia species in soft ticks, including a Rickettsia africae-like genotype (in association with a bat species, which is not known to migrate to Africa), three haemotropic Mycoplasma genotypes in Ixodes simplex, and Bartonella genotypes in I. ariadnae and I. vespertilionis. CONCLUSIONS: Rickettsiae (from both the spotted fever and the R. felis groups) appear to be associated with soft rather than hard ticks of bats, as opposed to bartonellae. Two tick-borne zoonotic pathogens (R. helvetica and A. phagocytophilum) have been detected for the first time in bat ticks. The present findings add Asia (China) to the geographical range of R. lusitaniae, as well as indicate the occurrence of R. hoogstraalii in South Africa. This is also the first molecular evidence for the autochthonous occurrence of a R. africae-like genotype in Europe. Bat haemoplasmas, which are closely related to haemoplasmas previously identified in bats in Spain and to "Candidatus Mycoplasma haemohominis", are reported here for the first time from Central Europe and from any bat tick.

RESUMO

Soil dwelling Uropodina mites were collected from a primary lowland rainforest in Amazonian Peru. The species found belong to three different families. A new diagnosis and the type genus of Tetrasejaspidae fam. nov. are given, and the family is recorded from Peru for the first time on the basis of Tetrasejaspis sellnicki Hirschmann, 1973. Two rotundabaloghid mites were collected (Rotundabaloghia (Circobaloghia) magna Hirschmann, 1992 and Rotundabaloghia (Circobaloghia) iquitosensis Hirschmann, 1992), both already reported from Peru. A new species (Origmatrachys peruensis sp. nov.) from the family Trachyuropodidae was collected in large numbers from soil, and is described on the basis of females, males, nymphs and larvae. This is the first description of the protonymphs and larvae of Origmatrachys. The new species differs from the previously described ones in the basis of sculptural pattern of dorsal, ventral, sternal shields and the length of the setae in the central part of the dorsal shield. A new key to the known adults and deutonymphs of Origmatrachys is given.

RESUMO

The association of an uropodid mite with a solitary eumenine wasp is reported for the first time. Five mite specimens were found on a specimen of the wasp Zethus pallidus Smith, 1857, collected in southeastern Brazil. The mites are described as a new species, Oplitis ticumbi Kontschán & Bernardi sp. nov. In addition some notes on the biology of these mite specimens associated with Z. pallidus are presented.

RESUMO

We describe two new species of Dinychus Kramer, 1886 from fragments of the former Gondwanaland supercontinent. Dinychus indica sp. nov. from India belongs to the Dinychus woelkei-group It differs from the previously known Dinychus species on the basis of the sculptural pattern of the sternal and genital shields of female. The female of Dinychus chilensis sp. nov. from Chile has a quadrangular genital shield, which is a unique character state in the genus Dinychus. New keys to the Central and South American Dinychus and to Dinychus woelkei-group are presented.

RESUMO

Kaszabjbaloghia Hirschmann, 1973, distributed in South-America, is characterized by the following combination of characters: reduced marginal shield, posteromarginal setae placed on membranous cuticle on the dorsal idiosoma, linguliform genital shield in females, oval or egg-like genital shield bearing one pair needle-like setae in males, and the characteristic shape of peritremes. In this contribution, I provide short redescriptions of the known species of Kaszabjbaloghia and describe a new species, K. ecuadorica sp. nov., from Ecuador. The new species is similar to K. kaszabi Hirschmann, 1973, but differs from the latter in the ornamentation of genital shield of the female and the number of sternal cavities. Additionally, we transfer K. hirschmanni Hiramatsu, 1978 to Hutufeideria Hirschmann & Hirmatsu, 1977 (as Hutufeideria hirschmanni (Hiramatsu, 1978) comb. nov.) on the basis of the following: setation of dorsal shield, ornamentation of caudal part of the dorsal shield, shape of hypostomal setae, shape of internal malae and setation of the palp. An identification key to the species of Kaszabjbaloghia is also provided. Original illustrations and scanning micrographs are provided for all species.
