AI Article Synopsis
- Two new species of monopisthocotylean parasites have been discovered in the gills of the Peruvian sea catfish in the Tumbes region of Peru.
- One species is characterized by a T-shaped accessory piece and a worm-shaped termination, while the other features a sledgehammer-shaped accessory piece and a unique jellyfish-shaped structure.
- Genetic analysis placed the new species within a group of parasites affecting marine catfishes, increasing the total known species to seven, and marking the first identification of such species in Peru.
Article Abstract
As part of a parasitological survey, several specimens of two new monopisthocotylean species, sp. nov. and sp. nov. (Dactylogyridea, Dactylogyridae), were collected from the gill filaments of the Peruvian sea catfish (Siluriformes, Ariidae) off Puerto Pizarro, Tumbes region, Peru. sp. nov. is characterised by an MCO with a T-shaped distal end and an accessory piece that is ribbed and expanded proximally with a worm-shaped termination. sp. nov. is typified by its MCO, which has a sledgehammer-shaped distal end and an accessory piece with a claw-shaped distal end. Additionally, sp. nov. is characterised by its jellyfish-shaped onchium. A partial 28S rDNA sequence was obtained from sp. nov., and a phylogenetic analysis was conducted. This analysis revealed the phylogenetic position of sp. nov. within a clade comprising monopisthocotylean parasites of diadromous and marine ariid catfishes, including spp., spp., Kritsky, Shameem, Kumari & Krishnaveni, , and Lim, 1995. This finding brings the number of known species to seven and represents the first described species infecting marine catfishes from Peru.

Monogeneans of the genus Dactylogyrus Diesing, 1850, the largest genus in the family Dactylogyridae, mostly parasitize the gills of cyprinoid hosts; however, only 3 Dactylogyrus' mitochondrial genomes (mitogenomes) are studied so far. The aim of this research is to extend our understanding of the mitogenomes of Dactylogyrus. We sequenced the mitogenomes of D.

Article Synopsis
- - African cichlids serve as important subjects for studying evolution and host-parasite dynamics due to their diverse species and specific parasites.
- - Researchers examined gill-inhabiting monogenean parasites from 18 cichlid species in Lake Victoria, discovering one species of Gyrodactylidae and identifying four new species of the Dactylogyridae family.
- - The study found that the monogenean parasites in Lake Victoria's cichlids have lower species richness and host-specificity compared to those in Lake Tanganyika, suggesting multiple colonization events of these parasites among the cichlid tribes.
