Itaborahia

Itaborahia is a fossil genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Bulimulidae. The genus is known only from the Brazilian Paleocene deposits of the Itaboraí Basin, in the state of Rio de Janeiro.[1]

Species[edit]

The only species currently in this genus is Itaborahia lamegoi Maury, 1935, although some other species were previously included within this genus.[1]

Cortana (gastropod)

Cortana is a fossil genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Bulimulidae. The genus is known only from the Brazilian Paleocene deposits of the Itaboraí Basin, in the state of Rio de Janeiro.[1] The most characteristic feature of the genus is its apertural armature.[1]

Species[edit]

The sole species in the genus is Cortana carvalhoi (Brito,1967).[1]

Bulimulidae

Bulimulidae is a taxonomic family of medium-sized to large, air-breathing, tropical and sub-tropical land snails, terrestrial pulmonate gastropod molluscs in the superfamily Orthalicoidea.[2]

Distribution[edit]

Distribution of species in the family Bulimulidae includes Ecuador (9 genera)[3] and other South American countries.

Fossil record[edit]

The family's oldest fossil record dates from the Middle Paleocene of Brazil (Itaboraí Basin).[4]

Anatomy[edit]

Members of this family have a haploid chromosome number between 26 to 30 (according to the values in this table).[5]

Shells of species within Bostrycinae are with a smooth protoconch and genital organs are with a relatively long penis sheath (ca. 1/4–1/6 total phallus length).[6]

Taxonomy[edit]

Previously, the members of the Orthalicidae were also included in this subfamily, as the subfamily Orthalicinae, and the taxa listed here were placed in their own subfamily, the Bulimulinae.[7]

2005 taxonomy[edit]

Bulimulinae was placed in the family Orthalicidae according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005).[8]

The subfamily Bulimulinae included 3 tribes:[8]

  • Tribe Bulimulini Tryon, 1867 - synonyms: Bulimidae Guilding, 1828 (inv.); Berendtiinae P. Fischer & Crosse, 1872; Bothiembryontidae Iredale, 1937
  • Tribe Odontostomini Pilsbry & Vanatta, 1898 - synonym: Tomogeridae Jousseaume, 1877
  • Tribe Simpulopsini Schileyko, 1999

2010 taxonomy[edit]

Breure et al. (2010)[2] moved Bothriembryon to Placostylidae (since 2012 as Bothriembryontidae), elevated Bulimulinae to Bulimulidae and Odontostomini to Odontostomidae.[2]

2012 taxonomy[edit]

Breure & Romero (2012)[9] confirmed previous results from 2010, additionally they elevated Simpulopsini to Simpulopsidae.[9] There are three subfamilies within Bulimulidae:[9]

  • subfamily Bulimulinae Tryon, 1867
  • subfamily Peltellinae Gray, 1855
  • subfamily Bostrycinae Breure, 2012[9][6]

Genera[edit]

Genera in the family Bulimulidae include:

subfamily Bulimulinae

subfamily Peltellinae

subfamily Bostrycinae

within Bulimulidae, subfamily ?

unsorted, maybe within Bulimulidae (can be also either in Bulimulidae or Odontostomidae or in Simpulopsidae)
