短尾乌贼是宿主-微生物相互作用、行为和发育的新兴模型,但它们的物种多样性和分布仍不清楚。在这里,我们联合收割机线粒体和转录组序列与形态分析,描述了三种短尾乌贼(乌贼科:乌贼亚科)从琉球群岛,并比较它们与相关类群。一个琉球类型是以前未知的,并在这里描述为Euprymna brennerisp。另一个琉球类型在形态上与Sepiola parvaSasaki,1913不能区分。然而,分子分析将此分类群归入Euprymna Steenstrup,1887,另外的形态学研究导致了Euprymna的正式重新诊断,并将本种重新分配为Euprymna parvacomb。虽然没有发现来自第三琉球类型的成年人,但孵化的序列表明与E. pardalotaReid,2011,已知来自澳大利亚和东帝汶。广泛采样的转录组报告这里提供了一个基础,为未来的系统发育和比较研究。
Bobtail squid are emerging models for host–microbe interactions, behavior, and development, yet their species diversity and distribution remain poorly characterized. Here, we combine mitochondrial and transcriptome sequences with morphological analysis to describe three species of bobtail squid (Sepiolidae: Sepiolinae) from the Ryukyu archipelago, and compare them with related taxa. One Ryukyuan type was previously unknown, and is described here asEuprymna brennerisp. nov. Another Ryukyuan type is morphologically indistinguishable fromSepiola parvaSasaki, 1913. Molecular analyses, however, place this taxon within the genusEuprymnaSteenstrup, 1887, and additional morphological investigation led to formal rediagnosis ofEuprymnaand reassignment of this species asEuprymna parvacomb. nov. While no adults from the third Ryukyuan type were found, sequences from hatchlings suggest a close relationship withE. pardalotaReid, 2011, known from Australia and East Timor. The broadly sampled transcriptomes reported here provide a foundation for future phylogenetic and comparative studies.
