Notas de ixodologia: V - A propósito da validade de algumas espécies do gênero Amblyomma do continente americano (Acari: Ixodídoe)

Abstract

a) The species Amblyomma tapiri Tonelli Rondelli, 1937 and Amblyomma finitimum Tonelli Rondelli, 1937 are synonymous with Amblyomma cajennense Fabricius, 1787. Both species are based in differences of size, colour, punctations and form of the dorsal shield, presence or absence of ventral plates, size, form and direction of the spine of coxa IV. Such differences prouved to be only variations frequently observed in large lots or in cultures of Amblyomma cajennense. The revalidation of Koch's species Amblyomma tenellum Koch, 1844 and Amblyomma mixtum Koch, 1844 proposed by TONELLI RONDELLI as also of Amblyomma sculptum Berlese, 1888 and Amblyomma versicolor Nuttal et Warburton, 1908 cannot be accepted by the same reasons. b) Amblyomma beccari Tonelli Rondelli, 1939 and Amblyomma latepunctatum Tonelli Rondelli, 1939 are cospecific with Amblyomma scalpturatum Neumann, 1899 the same being true for Amblyomma myrmecophagium Schulze, 1935 and for Amblyomma brasiliense var. guianense Floch et Abonnenc, 1940, as previously stated. c) Amblyomma tasquei Floch et Abonnenc, 1940 is a good species but synonym with Amblyomma romitii Tonelli Rondelli, 1939 which has priority. d) Amblyomma curruca Schulze, 1936 is a synonym of Amblyomma parvum Aragao, 1908. e) Amblyomma deminutivum Neumann, 1899 represents a variation of Amblyomma dissimile Koch, 1844, a species whose internal spine of coxa IV may be poorly developed or even absent. f) Amblyomma nigrum Tonelli Rondelli, 1939 prouved to be synonym with Amblyomma paccae Aragao, 1911 the type representing a blackish specimen of the later species. g) Amblyomma brimonti Neumann, 1913 is a synonym of Amblyomma humerale Koch, 1844.
