Centrorhynchidae

Centrorhynchidae is a family of parasitic worms. Three species of these thorny-headed worms in the genus Centrorhynchus were found to parasitize birds of prey and owls Slovakia. These hosts include Buteo buteo, Buteo rufinus, Falco tinnunculus, Asio otus, Strix aluco, Strix uralensis and Tyto alba.

 * Centrorhynchus nahuelhuapensis Steinauer, Flores and Rauque, 2020

C. nahuelhuapensis was found in the intestine of the rufous-legged owl (Strix rufipes) in Patagonia, Argentina. The proboscis is armed with 31–33 rows of hooks 16 or 17 hooks per row. The hooks in each row are distributed into 5 true hooks, 4 transitional hooks, and 7–8 spiniform hooks. It has three cement glands. The worm has a filiform body. Phylogenetic analysis was conducted using the small and large ribosomal subunits confirming the placement of this species in the genus Centrorhynchus.
