Supplementary Figure S1. Statistical parsimony network of Cardiodectes based on 18S rDNA sequences. The network illustrates the genetic differentiation between the newly described Red Sea species, Cardiodectes tofaili n. sp., and the Japanese species, Cardiodectes sp., with the latter being the only sequence available from this genus in GenBank (LC777455). Each circle represents a haplotype, with species distinguished by a different pattern.

Supplementary Table 1. Metadata on the collection of the host Vinciguerria mabahiss infected by the mesoparasitic Cardiodectes tofaili sp. nov., during the Red Sea Decade Expedition (RSDE) 2022. Data are displayed for complete individuals with morphometric measurements. Twelve incomplete host fish infected with copepods are not shown as measurements could not be obtained. Access here
