Carrier snails of the family Xenophoridae have long been celebrated by naturalists for their behavior of collecting and affixing foreign objects to their shells. We present the first molecular species delimitation of carrier snails (family: Xenophoridae), using cox1 sequences from 562 specimens encompassing 81% of valid species and all genera in this family. Integrating alpha-taxonomic data, we formalize five new species in descriptions-Xenophora simulans sp. nov., Xenophora brevis sp. nov., Onustus procellosus sp. nov., Collector altissimus gen. nov. et sp. nov., Collector alienus gen. nov. et sp. nov.-and recommend further investigations into other promising clades with potentially undiscovered species, pending corroboration from nuclear loci. This case study highlights the potential of species discovery using single-locus delimitation methods. We established a baseline framework for morphological species delimitation in Xenophoridae, showing that specimens distinguished only by subtle morphological characters often interpreted as intraspecific variation can exhibit species-level genetic divergence.","PeriodicalId":24072,"journal":{"name":"Zootaxa","volume":"5839 3","pages":"439-469"},"PeriodicalIF":0.9,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148399698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specimens of this Nigerian-Cameroonian highland range-restricted species are compared with specimens of the more widespread Chlorocypha spp. from western Nigeria. The broad and blunt-tipped cerci of A. centripunctata is adjudged to be a reliable larval diagnostic character of the species from Chlorocypha spp., in addition to a greater body size (F-0 ≥ 16 mm). The montane habitat requirements of larvae of A. centripunctata include lotic systems with good riparian cover, coarse particulate organic matter, high dissolved oxygen saturation and low water temperature. Given the conservation importance of this endangered species, knowledge of its larval identity and ecology could aid more-informed conservation interventions. As odonate larval collections are a major part of the results of hydrobiological assessments for conservation decision makers, an in-depth study of their species-level descriptions is recommended in West Africa.","PeriodicalId":24072,"journal":{"name":"Zootaxa","volume":"5839 3","pages":"577-588"},"PeriodicalIF":0.9,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148399669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reports generated over the years question the validity of the two species, as their morphometry and most of the morphological features overlap. Additionally, the molecular data revealed the representatives of H. crassatus cluster with one of the two main lineages of the polyphyletic H. digonicus. So far, H. crassatus has neither been reported from Poland nor from other parts of Europe, while H. digonicus has been recognized as a commonly occurring species in Poland and associated with many plants. The studies of three Helicotylenchus populations from Poland, initially identified as H. cf. digonicus revealed their high molecular and morphological resemblance to the recently characterized populations of H. crassatus from Canada. Therefore, this work extends the characteristics of H. crassatus, expands its occurrence to the European continent and discusses it in the context of the similarities with H. digonicus, with which it is often confused.","PeriodicalId":24072,"journal":{"name":"Zootaxa","volume":"5839 3","pages":"547-562"},"PeriodicalIF":0.9,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148399673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detailed morphological descriptions, diagnostic illustrations and scanning electron micrographs are provided. Newly described species, along with recently reported species are incorporated into a revised cladistic framework based on 36 morphological characters across 25 taxa. The analysis supports the monophyly of the genus and separates it into South East Asian and South Asian clades. Within the South Asian clade, the Indian species forms a separate monophyletic group and in the South East Asian clade, O. chenae, O. subchenae, O. zhuwu, O. kanoi, and O. complexipalpis form a cluster. This further substantiates the phylogeographic structuring and micro-endemism within South Asian Onomastus. The study highlights the restricted distribution of the genus within the sky islands of the Western Ghats, rendering them particularly vulnerable to rising global temperatures and habitat loss.","PeriodicalId":24072,"journal":{"name":"Zootaxa","volume":"5839 3","pages":"507-526"},"PeriodicalIF":0.9,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148398724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
