Padrão morfológico e ciclo de vida de Eutetranychus banksi (Acari: Tetranychidae) de diferentes locais e hospedeiros

Eutetranychus banksi (McGregor, 1914) is a phytophagous, polyphagous and cosmopolitan species recorded on 23 plant families in 24 countries in North, Central and South Americas, Europe, Asia, and Africa. Specimens of E. banksi present morphological variability among individuals of the same population and also among populations from different host species, being commonly referred to as a polytypic species, despite the fact that studies based on meristic comparisons of these populations are lacking. Also, there is no data available in the literature on the biological life tables of E. banksi on different hosts. Specimens collected in Brazil, Guadeloupe, Martinique, Mexico, and Paraguay were investigated in order to recognize morphological patterns among populations from different localities and hosts. A redescription of the species is provided based on data both from literature and new observations. Also, the biological cycle on three hosts, experiments of hosts exchange and the possibility of interbreeding in individuals originating from different populations were evaluated. Significant differences in the morphology of the females of different populations were detected when comparing the different hosts. The length of the dorsal pairs of setae v2, sc2, c1, c3, e1 and h1 differentiated the specimens of the populations collected from Citrus sp. from those of Hevea brasiliensis Muell. Arg. and Pachira aquatica Aubl.. Herein we observed significant variation among the life cycle of this species on the three hosts studied. When a substrate different from the one where the mites were collected was used for the biological cycle essay, significant variation was observed in several parameters such as average oviposition rate, events of arrenothoky, and sex ratio. Interbreeding with populations collected from Citrus sinensis and P. aquatica resulted in no descendants, although mating was observed.

On the identity of Pterodectes ralliculae Atyeo and Gaud, 1977 (Astigmata: Proctophyllodidae)

The feather mite Pterodectes ralliculae Atyeo and Gaud, 1977 (Proctophyllodidae: Pterodectinae) is the only proctophyllodid known from rallids (Gruiformes, Rallidae). Based on re-examination of the type material, this mite species is redescribed and transferred to the genus Montesauria Oudemans, 1905, Montesauria ralliculae (Atyeo and Gaud, 1977) comb. nov. This redescription brings details of structures missed in the original description: in both sexes, vertical setae ve are present, setae mG on genu II, gT on tibia II and wa on tarsi I and II are present; in males, the rudimentary epimeral sclerites rEpIIa are present and the female is illustrated for the first time. The transfer of P. ralliculae to Montesauria was also supported by the preliminary phylogenetic hypothesis recently proposed for the subfamily Pterodectinae.

Field-theoretic approach for systems of composite hadrons

Systems containing simultaneously hadrons and their constituents are most easily described by treating composite hadron field operators on the same kinematical footing as the constituent ones. Introduction of a unitary transformation allows redescription of hadrons by elementary-particle field operators. Transformation of the microscopic Hamiltonian leads to effective Hamiltonians describing all possible processes involving hadrons and their constituents.

A review of the Neotropical Lauxaniidae genus Paracestrotus Hendel, 1925 is presented with redescription of P. gibbosus Hendel, 1925 and the description of a new species, P. pulchripennis sp. n., from Brazil, Pará, including illustrations and a key. Copyright © 2006 Magnolia Press.

Revision of Nathan Banks type specimens of Bdellidae Dugès (Acari: Trombidiformes) of the Museum of Comparative Zoology, Cambridge

In this article, seven Bdellidae Dugès (Acari: Trombidiformes) of the Museum of Comparative Zoology, originally described by Nathan Banks are studied: Cyta americana (Banks, 1902), Bdella tenella Banks, 1896, Bdella utilis Banks, 1914, Bdella californica Banks, 1904, Bdella cardinalis Banks, 1894, Bdella peregrina Banks, 1894 and Bdella brevitarsis Banks. Bdella tenella and Bdella californica are transferred to the genera Spinibdella and Bdellodes, respectively. Bdella brevitarsis, previously a nomen nudum, is herein described for the first time under the genus Hexabdella. http://zoobank.org/urn:lsid: zoobank.org:pub:A18C8C10-8C8A-4873-AF0B-D1A9164CD7E8 © 2013 Copyright 2013 Taylor & Francis.
