Chen, Zhe-Yu, 2021, A review of Coptocheilus Gould, 1862 from China, with description of a new species (Gastropoda: Caenogastropoda: Pupinidae), Journal of Natural History 54 (41 - 42), pp. 2703-2712 : 2704

Coptocheilus Gould, 1862 裂唇螺属

Coptocheilus Gould, 1862: 282 .; Schistoloma Kobelt, 1902: 298 (replacement name of Coptocheilus Gould, 1862 ).; Pinteria Varga, 1972: 134 (type species: Pinteria croesus Varga, 1972 , by original designation)

Type species. Cyclostoma altum Sowerby I, 1842 , by original designation

Remarks. Kobelt (1902) established Schistoloma as a replacement name of Coptocheilus Gould, 1862 , by treating Coptocheilus as a junior homonym of Coptochilus Amyot & Serville, 1843 [ Hemiptera ]. However, according to the ICZN guideline ‘One-letter difference’ ( ICZN 1999, Art. 56.2), Coptocheilus Gould, 1862 , is not a junior homonym of Coptochilus Amyot & Serville, 1843 , and Kobelt’s replacement name was unnecessary. Also, Coptocheilus was used as valid after 1899 ( Fulton 1903), Art. 23.9 ( ICZN 1999) and cannot be used to conserve the name Schistoloma over Coptocheilus . Bui and Páll-Gergely (2020) already restored the name Coptocheilus while this manuscript was in preparation. The Chinese name remains unchanged to maintain taxonomic stability.
