This leads to uncertainty in the phylogenetic interrelationships even at the family-level, particularly for the former Lernaeodiscidae. This family was abolished based on molecular data, however, the morphological description for lernaeodiscids remains incomplete. Here we describe a morphology of <em>Lernaeodiscus rybakovi</em> parasitizing the porcelain crab <em>Pachycheles stevensii</em>, using a variety of methods. The externa's lacunar and muscular systems are “Kentrogonida”-type in general, but exhibit notable deviations, including an atypical mantle opening formed partly by the visceral mass and a distinct dorso-ventral bridge. The interna displays a previously undescribed organization: a prominent main trunk giving rise to flattened primary branches and tubular secondary rootlets. Muscular fibers are absent in the interna; only sparse actin filaments are present, suggesting alternative mechanisms of nutrient transport. Two invasive rootlet types—goblet-shaped organs and neuropil rootlets—interact with host nervous tissue, and their ultrastructure differs from that of other rhizocephalan families. Additionally, we describe an aberrant trophic rootlet filled with concentric extracellular matrix layers, likely reflecting localised misregulation of cuticle production. Our findings, together with molecular evidence, suggest that <em>Lernaeodiscus</em> may represent an independent lineage, warranting exclusion from Peltogastridae and possibly reinstatement of Lernaeodiscidae. Broader sampling and multigene phylogeny are needed to clarify its rank and composition.</div></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"321 ","pages":"Pages 198-212"},"PeriodicalIF":1.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145977965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the shell and mantle structure of the rhynchonellide <em>Hemithiris psittacea.</em> The shell consists of an organic uppermost sheet, comprising mucopolysaccharide and periostracal layers, and a mineralized part composed of primary and secondary layers. The secondary layer is formed by fibers, enclosed in organic sheaths. We identified distinct mantle epithelial cell types: inner, columnar, oval, lobate, and vesicular cells, as well as two types of outer epithelial cells. Each cell type exhibits ultrastructural features that correspond to putative specialized functions: columnar and lobate cells secrete the mucopolysaccharide layer; the vesicular cells synthesize the periostracum; the first type of outer epithelial cells contributes to primary layer secretion; and the second type produces the fibers of the secondary layer. Oval cells in the mantle groove display undifferentiated morphology, supporting the existence of a putative generative zone in rhynchonellide brachiopods. Our analysis identifies three distinct morphological and functional zones of the shell. The primary zone is the marginal shell region, consisting only of the primary layer. The transitional zone exhibits progressive changes in both fiber morphology and epithelial cell dimensions without constant relative position of cells and fibers, while the stable pattern zone maintains regular cells and fibers arrangement. Based on these findings, we propose regional modifications to the classical conveyor belt model for mantle growth and shell thickening in rhynchonelliform brachiopods. In the transitional zone, several cells may cooperatively secrete fibers and translocate the fiber during synthesis, while in the stable pattern zone each cell produces two adjacent fibers throughout its lifespan. In the posterior zone shell secretion terminates.</div></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"321 ","pages":"Pages 371-384"},"PeriodicalIF":1.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective was to identify the historical processes—particularly geological and climatic events—that shaped the diversification and current distribution of AGG species. To achieve this, we inferred a time-calibrated phylogeny, reconstructed ancestral area distributions, and analyzed patterns of dispersal and vicariance throughout the group's evolutionary history. Our results indicate that the AGG began its diversification approximately 13–10 million years ago during the Late Miocene, a period marked by significant geomorphological and climatic changes across the main basins of the La Plata system, including the Paraguay, Paraná, and Uruguay basins, as well as adjacent lowlands. Marine incursions together with tectonic activity and broader paleogeographic changes during this time reconfigured the drainage patterns of major basins, driving dispersal, isolation, and diversification within the group.
