Five years ago, the Panamanian evolutionary lineage (EL) C12 was uncovered along with four other ELs in an integrative phylogenetic investigation of worldwide Carychiidae. Since EL C12 lacked shell material post-molecular analysis to serve as a museum voucher, it remained undescribed. Now, after recent collection efforts of C12 and the congener, Jochum & Weigand, 2017 at their original Panamanian sites, C12 is morphologically described and formally assigned the name, Jochum, In sync with recent taxonomic treatment of the genus, computed tomography (CT) is used in this work to differentiate shells of from geographically-proximal, Caribbean, North and Central American congeners. Recent material of topotypic (Chitty, 1853) and undamaged were additionally CT-scanned and assessed in the comparative analyses.
五年前，在一项对全球 Carychiidae 进行的综合系统发育研究中，巴拿马进化谱系（EL）C12 与其他四个进化谱系一同被发现。由于 EL C12 在分子分析后缺乏可作为博物馆凭证的壳材料，因此一直未被描述。现在，在最近对 C12 及其同属物种进行了采集工作后，Jochum 和 Weigand 在其原始巴拿马地点于 2017 年进行了研究，C12 得到了形态学描述并被正式命名为 Jochum。与该属最近的分类处理同步，本研究使用计算机断层扫描（CT）来区分 C12 的壳与地理上相近的加勒比地区、北美和中美洲同属物种的壳。此外，对模式标本（Chitty，1853）的最新材料和未受损的 C12 进行了 CT 扫描，并在比较分析中进行了评估。
