The new species is conchologically similar to Cathaica fasciola (Draparnaud, 1801). The new species and C. p. montana, a subspecies of C. pyrrhozona (Philippi, 1845), the type species of Cathaica, share a similar structure of the dart-sac apparatus, in having one proximal accessory sac on the right side of dart sac, both mucous glands and the proximal accessory sac entering the dart-sac chamber. However, the distance between the dart-sac septum and the entrance of the mucous glands is distinctly shorter in the new species than that in C. p. montana. The genital anatomy of these two taxa suggests that the structure of the inside of the dart-sac apparatus deserves special attention of understanding systematics of the bradybaenine snails. In addition, the presence of dense cilia on the septum of the dart sac in the new species is newly reported for the subfamily Bradybaeninae.","PeriodicalId":50220,"journal":{"name":"Journal of Conchology","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140256405","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}
