A new species of Hexabdella (Acari: Bdellidae) from Brazil

A new species of the genus Hexabdella Van der Schyff, Theron & Ueckermann, Hexabdella cinquaginta sp.n. is herein described, representing the second species of the family Bdellidae from the neotropical region. It can be distinguished from H. singula by its lobed striae on lateral margins of hysterosoma and by the leg chaetotaxy. A key to species of the genus is presented. Copyright © 2007 Magnolia Press.

Description of larva of Amblyomma romitii (Acari: Ixodidae) by optical and scanning electron microscopy, including porotaxy and phylogenetic analysis

The description of the larva of Amblyomma romitii Tonelli-Rondelli is based on optical and scanning electron microscopy. Larvae were obtained under laboratory conditions from an engorged female collected on capybara from Rurópolis municipality, State of Pará, Northern Brazil. Several characters are presented including the chaetotaxy of idiosoma, palpi and Haller's organ. The larval porotaxy (topographical and numerical patterns of integumentary structures) was presented and compared to that of the other Amblyomma spp. larvae. The mitochondrial 16S rDNA partial sequence of A. romitii generated in the present study was aligned with sequences previously determined for other Amblyomma species available in Genbank and with some species presently sequenced. The larval morphology of A. romitii and other Neotropical Amblyomma spp. larvae is discussed as well as the DNA sequence and its phylogenetic position among other species of the genus. © 2012 Springer Science+Business Media Dordrecht.
