Morphological revision of the hyperdiverse Brueelia - complex (Insecta: Phthiraptera: Ischnocera: Philopteridae) with new taxa, checklists and generic key Author Bush, Sarah E. text Zootaxa 2017 2017-08-31 4313 1 1 443 journal article 32249 10.11646/zootaxa.4313.1.1 d8cc2cd8-8410-49aa-a75d-7a41d9f52b26 1175-5326 883161 A5Fdfba5-F992-44A8-84C2-1756C943C19B Nirmus brasiliensis Giebel, 1874 Type host. Tangara mexicana brasiliensis (Linnaeus, 1766) —turquoise tanager. Remarks. The first mention of this species ( Giebel, 1866: 367 ) only reads that it is “yellowish, without markings” (our translation). Later, Giebel (1874: 134) provided additional information with enough detail to be considered a formal description. Hence we consider the proper author and date of Nirmus brasiliensis to be Giebel, 1874 . Unfortunately, even with the additional information provided by Piaget (1880: 160) , the description of this species is not good enough to allow us to place it into any genera of the Brueelia -complex. Only one individual was ever collected ( Giebel, 1866: 367 ), but it was in the destroyed with the Halle Collection ( Clay & Hopkins 1955 ). Additional collections from the type host are necessary to determine the taxonomic placement of this enigmatic species.
