Nota sobre um Mallophago Austrogoniodes bifasciatus (Piaget) parasita do pinquin

The A. redescribes Austroçoniodes bifasciatus (Piagei 1835) found on Speniscus magellanicus from Puerto Deseado, Sta, Cruz, Rep Argentina, and puts in the synonyrny of the above-spccies, A. sirutheus Harrison 1915, collected on Catarrhactes scateri (=EudYi'tes selateri) frorn the neighbourood of New Zeland. He states that this species had already been recorded by Waterston 00 Spheniscus demersus from South África. 50, once more, the phylogenetic and paleogeographie values of the study of Mallophaga, is evidenced because it seems that the mutability of these ectoparasêtes is lower than that of b.rds, He finds that the present distribution of «p:nguin1l» and the occurrence of a sarne species of Mallophaga on «pinguins» inciding in three differeIJt zoogeographical zones could be explain 'by Wegener's theory notwithtandíng, therefore, tihe possíbility of passive distribution, already recorded with martine birds, on floating ice in the zone of western wind currents.
