    Abstract:
    A new species of Centrorhynchus (Centrorhynchidae) with receptacle insertion at the posterior third of the proboscis is described from the pheasant crow Centropus sinensis (Stephens) (Cuculidae) in Pakistan. Centrorhynchu sglobirostris n. sp. is similar to the 98 other known species of Centrorhynchus Lühe, 1911 in having long cylindrical trunk with anterior dilation and transverse anastomoses of the secondary lacunar vessels. However, specimens of C. globirostris differ from all other species of the genus by having a unique globular proboscis not divided into anterior proboscis with rooted hooks and posterior proboscis with rootless spines. Posterior hooks of C. globirostris emerge at the level of the receptacle insertion and are uniquely fully rooted. Sequencing and phylogenetic analysis of C. globirostris 18S and 28S ribosomal RNA genes reveals the genetic and evolutionary relationships between C. globirostris and other members of Centrorhynchidae which have representative orthologs in public databases. Comparison to known acanthocephalans confirms appropriate inclusion in the genus Centrorhynchus.
