Шаблон:Short description Шаблон:Speciesbox
Ba humbugi is the only species and therefore the type species in the genus Ba, a genus of land snail, belonging to the family Charopidae. Both the genus and the species were named by the American malacologist Alan Solem. The genus is endemic to the Fijian island of Viti Levu, and Шаблон:Not a typo is an endangered species.
Taxonomic history
Alan Solem, the curator of invertebrates at the Field Museum of Natural History, created the genus Ba for his newly-described species Шаблон:Not a typo.Шаблон:Sfnp Solem based his description of the type species Шаблон:Not a typo on a holotype which the American malacologist Yoshio Kondo had collected in 1938 and three paratypes. One paratype was deposited in the Field Museum; the remaining specimens in the type series were deposited in the Bishop Museum.Шаблон:Sfnp
Etymology
Solem chose the generic name Ba after Ba District, Fiji, which extends into Шаблон:Not a typoШаблон:'s range. This led to him having an "irresistible impulse" to name the type species Шаблон:Not a typo,Шаблон:Sfnp in reference to the character Ebenezer Scrooge's catchphrase "Bah! Humbug!" from Charles Dickens's novella A Christmas Carol. One review of Solem's monograph naming this species said his choice in taxa names "may either lighten the reader's day or engender hostility", giving this binomen as an example.[1]
Distribution
Шаблон:Not a typo is endemic to Fiji.[2] It is found in the interior of Viti Levu, an island in Fiji, at elevations of Шаблон:Convert.Шаблон:Sfnp The holotype was collected in dense forest on Mount Nangaranambulata at an elevation of Шаблон:Convert. Two paratypes were collected on the top of Mount Korobamba at an elevation of Шаблон:Convert. The third paratype was collected in the Sanganaoreva area Шаблон:Convert inland of Ngaloa, Nuku District at an elevation of Шаблон:Convert.Шаблон:Sfnp
Description
Ba is characterized by having a high spire and an umbilicus which is either completely closed or slightly laterally cracked. There are only 3⅛–3½ whorls, and its apical sculpture consists of about a dozen spiral cords. There are no barriers to its aperture.Шаблон:Sfnp Шаблон:Not a typo has a shell with a diameter of Шаблон:Convert. The height-to-diameter ratio ranges from 0.752 to 0.842.Шаблон:Sfnp Its shell is a light reddish-yellow; its periostracal extensions are an almost black dark brown.Шаблон:Sfnp The body is yellow-white and lacks any sort of dark markings.Шаблон:Sfnp
Biology
Шаблон:Not a typo is sympatric with Sinployea irregularis; both species were found under the same log.Шаблон:Sfnp It is probably strictly terrestrial due to a lack of black marks on its body.Шаблон:Sfnp
Conservation status and threats
According to the IUCN Red List, Шаблон:Not a typo is endangered.[2] They note that only four specimens have been found despite many surveys on Viti Levu over a century and a half. The IUCN estimates an area of occupancy of Шаблон:Convert, and its habitat continues to decline due to deforestation. The IUCN believes invasive species, such as the Pacific rat, black rat, house mouse, and various invasive ant species, also negatively affect Шаблон:Not a typo. The IUCN predicts it would be detrimental if the invasive giant African snail, rosy wolf snail, or the New Guinea flatworm were introduced to Viti Levu.[2]
