This study assessed the prevalence of C. conanobrieni in the southwestern Caribbean Sea; Costa Rica and Panama. Brooding females of P. argus were collected by fishermen near Punta Uva beach, Costa Rica (n = 17), and Guna Yala, Panama (n = 19) and examined for the presence of C. conanobrieni. Prevalence of C. conanobrieni in brooding lobsters, determined as the presence/absence of adults, juveniles, encysted juvenile worms, or carcinonemertid egg masses was 47.06% and 31.58% in Costa Rica and Panama, respectively. Moreover, when indirect evidence (empty capsules and/or dead embryos presumably attacked/consumed by worms) of the presence of C. conanobrieni in brooding lobsters is considered in addition to direct evidence, prevalence of C. conanobrieni in brooding lobsters was 64.71% and 47.37% in Costa Rica and Panama, respectively. The observations suggest that this parasitic worm completes its life cycle locally in the southwestern Caribbean. Notably, a Maximum Likelihood phylogenetic analysis based on a fragment of the mitochondrial cox1 gene clustered two specimens collected in Costa Rica together with four other specimens previously collected in Saint Kitts into a single fully supported monophyletic clade that segregated from a second clade containing six specimens of C. conanobrieni collected in Colombia, Florida, and Saint Kitts. The barcoding analysis suggests that there is an undescribed species of Carcinonemertes, anatomically like C. conanobrieni, infecting P. argus in Costa Rica.","PeriodicalId":74204,"journal":{"name":"Mitochondrial DNA.

Although key features of some dictyostelid mitogenomes have been identified, several aspects remain unclear, including core gene content, segmental arrangement, and differences between 18S rRNA and mitochondrial gene phylogenies. To address these gaps, we reconstructed two complete mitogenomes-from Cavenderia subdiscoidea and Dictyostelium sp. (TH18CC)-and analyzed mitochondrial genes from ten genera and six additional complete mitogenomes from public databases. A comparison of eight complete mitogenomes revealed a conserved core of 39 protein-coding genes, 17 tRNA genes, and three rRNA genes. Two distinct segmental arrangements were identified: Dictyostelium (except D. purpureum) exhibits an A-C-B pattern, while other genera display an A-B-C pattern defined by the clusters nad9-atp1, trnC(GCA)-atp9, and rnl-nad3. Phylogenetic analyses based on 18S rDNA and mitochondrial rns suggest the transposition between segments B and C occurred after D. purpureum diverged from other Dictyostelium species, potentially involving tRNA gene displacement. In contrast, the mitochondrial protein-coding gene phylogeny differs from the rRNA trees, indicating that these gene sets may have evolved independently. These findings advance our understanding of dictyostelid mitogenome structure and evolution.","PeriodicalId":74204,"journal":{"name":"Mitochondrial DNA.
