Acanthocephaloides irregularis
n. sp. (Arhythmacanthidae) is described from four species of marine fishes in the Gulf of Odessa and Sukhyi Lyman, Ukrainan Black Sea waters, making it the tenth species of the genus. The hosts are the combtooth blenny
Parablennius zvonimiri
(Kolombatovic) (Blenniidae), the mushroom goby
Ponticola eurycephalus
(Kessler) (Gobiidae), the tubenose goby
Proterorhinus marmoratus
(Pallas) (Gobiidae) and the black-striped pipefish
Syngnathus abaster
Risso (Syngnathidae). The new species is most similar to its closest relative,
Acanthocephaloides propinquus
(Dujardin, 1845), in proboscis shape and armature (12 longitudinal rows of 5 hooks) and the shape of the trunk, reproductive system and lemnisci, but differs in having randomly distributed trunk spines. These trunk spines are organised in circular rings of individual spines separated by aspinose zones. The new species is also unique in having an anterior trunk collar, a very large triangular cephalic ganglion, nucleated pouches at the posterior end of the proboscis receptacle, and hooks and spines with roots bearing anterior manubria. Valid and invalid species of
Acanthocephaloides
Meyer, 1932 are listed and a key to all ten species is included.
