Biology:Amborhytida
Amborhytida is a genus of land snails belonging to the family Rhytididae.[1] First described in 1974, members of the genus are endemic to New Zealand.
Description
Members of Amborhytida have one or two peripheral keels, no oblique peripheral cords, a reduced penis, and no spermatheca.[2]
Taxonomy
Amborhytida was described by Frank Climo in 1974, who described it as a subgenus of Rhytida.[3] Amborhytida was raised to genus level in 1999.[4][5] Phylogenetic analysis suggests that the members of Amborhytida diverged relatively recently in geological terms, within approximately 1.9 to 6.6 million years ago.[5] Hamish Spencer, Fred J. Brook and Martyn Kennedy (2006) suggest this is likely due to areas of the Aupōuri Peninsula being islands during the Pliocene, including Cape Reinga-North Cape, Tohoraha / Mount Camel, and the Karikari Peninsula.[5] Some of the closest genera to Amborhytida include Schizoglossa and Paryphanta, which separated into different genera between 9 and 11.6 million years ago.[5]
Ecology
Paryphanta busbyi and the Polynesian rat are a known predators of Amborhytida.[6][4] Amborhytida has been observed eating the eggs of Maoristylus ambagiosus.[7]
Distribution and habitat
The genus is endemic to New Zealand, found on the upper North Island and Manawatāwhi / Three Kings Islands.[8]
