Abstract
- Here we provide a morphological and molecular analysis of the taxonomic status of Cyathostoma (Cyathostoma) phenisci Baudet, 1937, a rare nematode parasite of African penguin Spheniscus demersus. Taxonomical evaluation is supplemented wi th ecological and epidemiological analysis of the nematode's occurrence in the African penguin's population. Tracheae and air sacs of 13 among the 94 necropsied birds (overall prevalence 13.8%) contained a total of 33 nematode specimens (20 females, 13 males). The highest prevalence was observed in juveniles (6 infected, 25%) and "blues" (6 infected, 14.3%), followed by nestlings (1 infected, 7.7%); no nematodes were found in adults. Our morphological and morphometric analysis shows that C. phenisci is closely related to another species, Cyathostoma (Cyathostoma) verrucosum (Hovorka & Macko, 1959). The doubtful status of the latter species was confirmed by molecular data: comparison of ITS2 sequence of C. phenisci with previously deposited sequences of C. verrucosum showed 96.3% similarity in this region. On this basis, we recognized Cyathostoma (Cyathostoma) verrucosum (Hovorka & Macko, 1959) as a synonym of Cyathostoma (Cyathostoma) phenisci Baudet, 1937.<br /> (Copyright © 2013 Elsevier Ireland Ltd.
