Name

• Testacella Lamarck, 1801: 96
  • Type species: unclear, either:
    • (1) if Testacella haliotoides Lamarck, 1801 is interpreted as available by combined genus/species description; and
      • (1a) if Testacella haliotidea Draparnaud, 1801 is not interpreted to be a subsequent usage thereof; then the type species is Testacella haliotoides Lamarck, 1801, by monotypy; or
      • (1b) if Testacella haliotidea Draparnaud, 1801 is interpreted to be a subsequent usage of Testacella haliotoides Lamarck, 1801; with spelling not conserved by prevailing usage under Art. 33.3.1; then the type species is again Testacella haliotoides Lamarck, 1801, by monotypy; or
      • (1c) if Testacella haliotidea Draparnaud, 1801 is interpreted to be a subsequent usage of Testacella haliotoides Lamarck, 1801; with spelling conserved by prevailing usage under Art. 33.3.1; then the type species is Testacella haliotidea Lamarck, 1801, by monotypy [this is the interpretation adopted by AnimalBase; or
    • (2) if Testacella haliotoides Lamarck, 1801 is not interpreted as available by combined genus/species description; and
      • (2a) if Testacella Draparnaud, 1801 is interpreted as a subsequent usage of Testacella Lamarck, 1801; then the type species is Testacella haliotidea Draparnaud, 1801, by subsequent monotypy in Draparnaud (1801); or
      • (2b) if Testacella Draparnaud, 1801 is not interpreted as a subsequent usage of Testacella Lamarck, 1801; then the type species of Testacella Lamarck, 1801 may not be fixed, as there were no originally included nominal species, and all subsequent uses of the name Testacella (with included nominal species) may refer to Testacella Draparnaud, 1801
• NOTES: on option (1) above, there are two possible interpretations of syntypes for Testacella haliotoides Lamarck, 1801:
  • (i) the types series includes both Maugé's material from Tenerife [=Testacella maugei Férussac, 1819] and the material figured by Favanne (assumed to be from France) [=Testacella haliotidea Draparnaud, 1801]; or
  • (ii) the types series includes only Maugé's material from Tenerife (since the material figured by Favanne was not listed in the scope of any particular species) [this is the interpretation adopted by Kennard & Woodward (1920), which makes Testacella haliotoides Lamarck, 1801 the valid name for Testacella maugei Férussac, 1819, as would designation of a Tenerife specimen as lectotype of Testacella haliotoides Lamarck, 1801, even in option (i) above]
• thus, the taxonomic type species for Testacella could either be the species currently known as Testacella haliotidea, or the species currently known as Testacella maugei, and while clearly distinct, these species are so closely related that it matters not which of them is taken to be the type species

Synonyms

• ?Testacella Draparnaud, 1801: 33, 99 [if Testacella Draparnaud, 1801 is not interpreted as a subsequent usage of Testacella Lamarck, 1801]
  • Type species Testacella haliotidea Draparnaud, 1801
    • Fixation: monotypy
