由于模式种（Solariella maculata Wood，1842）是上新世晚期的化石，因此将种归属于食腹足类属Solariella Wood，1842，并因此将种归属于Solariellidae Powell，1951，是复杂的。在过去，将种分配到属中已经证明是困难的，并且模式属有时对于不能容易地被分配到另一个属的种起着“废纸篓”的作用。根据最近的两个出版物提供了一个新的系统框架，提出了第一组的分子系统发育数据，我们重新评估的壳字符，是最有用的划分属。壳性状以前被认为是有限的分类学价值高于种的水平，但这是远非如此。虽然整体壳形不是一个可靠的特征，我们的工作表明，壳性状，沿着与齿舌和解剖特征，是有用的种属分配。早期真海螺（紧接着原海螺的区域）和鼻小柱的雕刻是特别有用的特征，在过去并没有经常用于区分属。然而，即使在本研究中使用的所有形态特征（壳，齿舌和眼睛）的组合，一些种仍然很难分配到属，在这种情况下，分子系统学数据是必不可少的。在本研究中，我们讨论了13个属-其中12个是恢复支持最近的分子系统学研究的分支-并提供形态特征来区分它们。我们描述了几个新的分类群：Chonospeiran。gen.（在以前的分子系统学研究中称为“进化枝B”），Phragmomphalinan。gen.（Bathymophilain部分在分子系统学研究）和Phragmomphalina vilvensin. sp.（模式种Phragmomphalinan. gen.）。我们合成HazuregyraShikama，1962年与MinoliaA。亚当斯，1860，Minolia subangulata Kuroda & Habe，1952与Minolia punctata A.亚当斯，1860年和M. Kuroda & Habe，1971和M.shimajiriensis（MacNeil，1960）。我们还提出了以下新组合：Bathymophila bairdii（Dall，1889），B. dawsoni（马歇尔，1979），B. regalis（马歇尔，1999），B. wanganellica（马歇尔，1999），B. ziczac（黑田& Habe in黑田，Habe & Oyama，1971）、裸裸绒螯蟹Chonospeira nuda（Dall，1896）、裸绒螯蟹C. iridescens（Habe，1961），C. ostreion（Vilvens，2009），C. strobilos（Vilvens，2009），冠状Elaphriella corona（Lee & Wu，2001），E. diplax（马歇尔，1999），E. Escheriana（马歇尔，1999），E. olivaceostrigata（Schepman，1908），E. opalina（Shikama & Hayashi，1977），Ilanga norfolkensis（马歇尔，1999），I. ptykte（Vilvens，2009），I. zaccaloides（Vilvens，2009），Minolia shimajiriensis（MacNeil，1960），M. watanabei（Shikama，1962）、箭叶扁管藻（Phragmomphalina alabida（马歇尔，1979）、黄扁管藻（P.迪亚德马（马歇尔，1999）、细隔扁管藻（P. tenuiseptum（马歇尔，1999）、真细basilicum（马歇尔，1999），S. exiguum（马歇尔，1999）和S. flavidum（马歇尔，1999）。
The assignment of species to the vetigastropod genusSolariellaWood, 1842, and therefore the family Solariellidae Powell, 1951, is complicated by the fact that the type species (Solariella maculataWood, 1842) is a fossil described from the Upper Pliocene. Assignment of species to genera has proved difficult in the past, and the type genus has sometimes acted as a ‘wastebasket’ for species that cannot easily be referred to another genus. In the light of a new systematic framework provided by two recent publications presenting the first molecular phylogenetic data for the group, we reassess the shell characters that are most useful for delimiting genera. Shell characters were previously thought to be of limited taxonomic value above the species level, but this is far from the case. Although overall shell shape is not a reliable character, our work shows that shell characters, along with radular and anatomical characters, are useful for assigning species to genera. Sculpture of the early teleoconch (the region immediately following the protoconch) and the columella are particularly useful characters that have not been used regularly in the past to distinguish genera. However, even with the combination of all morphological characters used in this study (shell, radular and eye), a few species are still difficult to assign to genera and in such cases molecular systematic data are essential. In the present study, we discuss 13 genera—12 of which were recovered as well-supported clades in recent molecular systematic studies—and provide morphological characters to distinguish them. We describe several new taxa:Chonospeiran. gen. (referred to as ‘clade B’ in previous molecular systematic studies),Phragmomphalinan. gen. (Bathymophilain part in molecular systematic studies) andPhragmomphalina vilvensin. sp. (type species ofPhragmomphalinan. gen.). We synonymizeHazuregyraShikama, 1962 withMinoliaA. Adams, 1860,Minolia subangulataKuroda & Habe, 1952 withMinolia punctataA. Adams, 1860 andM. gemmulataKuroda & Habe, 1971 withM.shimajiriensis(MacNeil, 1960).
