Comments on the validity of Haemaphysalis cinnabarina Koch, 1844 (Acari: Ixodidae), a taxon known solely by the type specimens from northern Brazil.

Keys to the adult ticks of Haemaphysalis Koch, 1844, in Thailand with notes on changes in taxonomy (Acari: Ixodoidea: Ixodidae).

Specimens of the genus Haemaphysalis collected in Thailand were examined, and a key to the adult of 24 species belonging to six subgenera is presented. We propose that H. wellingtoni Nuttall & Warburton, 1908, be placed in the subgenus Kaiseriana; H. obesa Larrousse, 1925, be moved from Segalia to Kaiseriana; and that H. cornigera Neumann, 1897, be removed from the species list of Thailand.

Redescription of Haemaphysalis (Rhipistoma) elliptica (Koch, 1844), an old taxon of the Haemaphysalis (Rhipistoma) leachi group from East and southern Africa, and of Haemaphysalis (Rhipistoma) leachi (Audouin, 1826) (Ixodida, Ixodidae).

Koch originally described only the male of Haemaphysalis (Rhipistoma) elliptica (Koch, 1844), which he named Rhipistoma ellipticum. For the past century, however, this name has been considered a junior synonym of Haemaphysalis (Rhipistoma) leachi (Audouin, 1826), or a nomen nudum. We redescribe here the male and larva of H. (R.) elliptica and describe the female and nymph for the first time. Ou...

Reestablishment of Amblyomma tenellum Koch, 1844 (Acari: Ixodidae).

Herein, Amblyomma tenellumKoch, 1844 (Ixodidae) is reestablished as a valid tick name and removed from the synonymy list of Amblyomma cajennense (Fabricius, 1787), while Amblyomma imitatorKohls, 1958, is relegated to a junior synonym of A. tenellum. Amblyomma tenellum is redescribed based on the examination of male type specimens collected by Deppe at the beginning of the 19th century in Mexico...

Brazilian distribution of Amblyomma varium Koch, 1844 (Acari: Ixodidae), a common parasite of sloths (Mammalia: Xenarthra).

Amblyomma varium, commonly known in Brazil as the "carrapato-gigante-da-pregui a" (sloth's giant tick) is found from southern Central America to Argentina. The present study adds information on the geographical distribution of A. varium, as well as on their hosts, based on material deposited in the main Brazilian collections and on the available literature. Eighty-two vials, containing 191 adul...
