Notas de Ixodologia: IV - considerações sôbre a nomeclatura de algumas espécies do gênero Amblyomma do Brasil e países limítrofes (Acari: Ixodidae)

An attempt is made to clear the nomenclature of some netropical species of the genus Amblyomma. Amblyomma myrmecophagium Schulze, 1933 and Amblyomma brasiliense guyanense Floch et Abonnenc, 1933, are synonyms of Amblyoma scalpturatum Neumann, 1906. Amblyomma superbrasiliense Schulze, 1941, is cospecific with Amblyomma incisum Neumann, 1906. Amblyomma ypsilophorum Schulze, 1941, is a synonym of Amblyomma cooperi Nuttal et Warburton, 1907.

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

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 Aragão, 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.

Notas de ixodologia: VI - Descrição da fêmea de Amblyomma Multipunctum, Neumann 1899 e redescrição do macho (Acari: Ixodídae)

The female of Amblyomma multipunctum Neumann, 1899 is described for the first time, the species being easily recognized by the unusual formula 5/5 in the female's hypostoma, the formula of the male's being 4/4. A redescription of the male is presented.

Notas de ixodologia: VII - Otocentor nitens Neuman, 1897) versus Anocentor columbianus Schulze, 1937 e comentários sôbre a rápida disseminação desse ixodideo no Brasil (Acari: Ixodidae)

Anocentor columbianus Schulze, 1937 is a synonym of Otocentor nitens (Neumann, 1897). Otocentor Cooley, 1938 becomes a synonym of Anocentor Schulze 1937. The correct name of the species is now Anocentor nitens (Neumann, 1897). In Brazil this species was first recorderd by ARAGÃO (in FLOCH and ABONNENC, 1945) in Belém do Pará and by FONSECA (1948) in Goyaz. New records from Minas Gerais and Matto Grosso are presented and a new host, the jaguar, Panthera onca, is added.

Notas sôbre a evolução do virus vacínico em animais silvestres da fauna brasileira

A note on the evolution of cow-pox virus in wild animals of Brazilian fauna. We have tried the sensibility of wild animals of Brazilian fauna to the cow-pox virus. The following specimens were submitted to experiences: Procyon cancrivorus, Hydrochoerus capybara, Cavea aperea, Coendu villosus, Didelphis aurita, Bradypus tridactylus, Euphractus sexcintus, Tamandua tetradactylus, Nasua narica, Dasyprocta aguti and Testudo tabulata. In all these animals, - excepting Bradypus tridactylus - we have obtained an infection with incubation (five days), aspect and duration similar to cow-pox of the laboratorial animals (calf and rabbit). In the Bradypus tridactylus howewer, the incubation was very long. Only after 30 days of inoculation we verified the infection with the formation of vesiculae and postulae.

Notas de ixodologia: IX. O complexo ovale do gênero Amblyomma

It was impossible to confirm either WARBUTON's conservative nor TONELLI RONDELLI's opposite belief on the number of valid species after studying many lots of ticks of the ovale group, mainly from Brazil. Two species are recognized: Amblyomma ovale Koch, 1844 and Amblyomma aureolatum (Pallas, 1772), corresponding respectively to A. fossum Neumann, 1898 and A. stratum Koch, 1844. A list of synonyms is presented. Both species are redescribed and intraspecific morphological variation show to be the cause of the multiplication of species by those working with insufficient material. Color plates of both species are presented and hosts and localities of captures are recorded.

Notas sôbre o gênero Colobogaster Solier, 1833, com a descrição de duas novas espécies da Região Amazônica: (Coleoptera, Buprestidae)

The study of materials belonging to several brazilian collections led us discover 2 new species of the genus Colobogaster which are here described. C. seabrai sp. n. seems to be related to C. puncticollis Waterhouse, 1882, from which it can be distinguished by: a) apical alitral tooth placed suturally, b) pronotum with 3 pairs of depressions, the 1st. pair transversal and conigous to the 2nd one, c) elitral suture brilliantgreen coloured but not the marginal edge, d) front without a horse-shoe shaped structure, e) pronotum with the discal region concolor. The structures of pronotum, the elitral and pronotal colour paterns and the genial morphology separate this one from other species of the genus. C. paraensis sp. n. is closely related to C. cupricollis Kerremans, 1897, but it is distinguished by the absence of depressions on the pronotum, by the elitral tooth placed suturally, by the abscence of humeral rip and by the general colour. Eleven other species were studied and their apical segment of the abdomen and scutellum were illustrated. It was also established the synonymy of C. ecuadoricus Obengerger, 1926.
