“…Dactylogyrus banghami has been reported from a variety of leuciscid host species and localities in eastern North America (see Hoffman [ 35 ]). However, according to Hanek et al [ 32 ] and Cloutman [ 16 ], D. banghami (= D. perlus ) represents a complex of morphologically similar species that needs to be revised, and in which D. perlus ( sensu stricto ) appears to be restricted on species of Luxilus Rafinesque [ 16 , 18 , 20 ]. The similarity of the species in the complex is given by the shape of both the anchors (see above in the remarks) and the MCO, which is composed of (i) a copulatory tube with a large base, having an anteriorly directed process (heel) and a slightly arched shaft with a diagonally truncated distal end, and (ii) an accessory piece medially bifurcated into two unequal rami (the left ramus with a hooked termination; the right ramus recurved posteriorly).…”

“…Prior to the present study, 132 nominal species of Dactylogyrus had been recorded from 113 species of native cypriniform fishes in North America [ 19 , 20 , 41 ]. The seven new species described herein raise the number of formally described Dactylogyrus species to 139 and the number of known host species for Dactylogyrus spp.…”

“…is undoubtedly closely related to the natural distribution of their cypriniform hosts, but records of these parasites vary widely in different regions of the world due to different levels of sampling efforts [ 30 , 41 ]. Up to now, a total of 140 native species of cypriniforms have been reported as hosts of 224 species of monogeneans in North America [ 19 , 20 , 41 , 47 ]. The majority of host species ( i.e.…”

“…The majority of host species (i.e., 110 spp.) belong to the Leuciscidae (Cyprinoidei) [20,41], the largest freshwater fish clade in North America, including more than 310 species [28]. The remaining host records belong to the Catostomoidei, with 75 species currently recognized [1].…”

Ribosomal DNA sequences are currently available for 32 morphologically recognized species of Dactylogyrus parasitizing Nearctic cypriniforms, but only 16 of them are assigned to nominal species. Herein, morphological data on 28 of the 32 species are provided, together with comments on their phylogenetic relationships in the context of the morphology of taxonomically important structures. Seven new species of Dactylogyrus are described from five species of leuciscids and one species of catostomids, as follows: D. aduncus n. sp. from Campostoma spadiceum, D. cloutmani n. sp. from Luxilus chrysocephalus isolepis, D. cornifrons n. sp. from Cyprinella venusta, D. fimbratus n. sp. from Rhinichthys cataractae, D. mcallisteri n. sp. from Semotilus atromaculatus, and D. chieni n. sp. and D. haneki n. sp. from Hypentelium nigricans. Four previously described species of Dactylogyrus, D. atromaculatus from S. atromaculatus, D. eos from C. neogaeus, D. parvicirrus from Notemigonus crysoleucas and D. perlus from L. c. isolepis, are redescribed and/or figured. As for the remaining 17 species, only the male copulatory organs (MCOs) taken from the respective hologenophores are illustrated. On the basis of phylogenetic analyses, two main clades of Nearctic Dactylogyrus were recognized and supported by the different morphology of the MCO. The first one included 22 strictly Nearctic species sharing the same MCO type with Dactylogyrus spp. parasitizing cyprinids likely of Asian origin. The second clade encompassed Dactylogyrus spp. with diverse MCO morphology and was placed in the sister position to Dactylogyrus spp. parasitizing European leuciscids and North-West African cyprinids.
