ResumoThe establishing of the new species of Argasine tick, Ornithodoros venezuelensis, by Brumpt, is, in my opinion, of considerable importance. This tick falls into the Ornithodoros talaje group and is very close to that species, but since Brumpt bases its separation on biological differences as well as on morphological characteristics, there seems to be no doubt in regard to the validity of venezuelensis as a species. However, it is now quite evident that in the past this species has been commonly mistaken for talaje and other closely allied species, especially by investigators of relapsing fever in South America. The species of tick mentioned by Franco, Toro, and Martinez (1911) as 0. turicata in connection with being the probable transmitting agent of relapsing fever at Muzo, Colombia, was very likely venezuelensis. This opinion is based on the illustrations accompanying their article as being more representative of this species than of turicata, and also owing to the fact that in 1924 I obtained a number of specimens of the Ornithodoros prevalent in Muzo, and they were all venezuelensis. No specimens of either turicata or talaje were present in the collection received from there.
