Taxonomy
editFivepearlus was first proposed as a monospecific genus in 2017 by Li Chunqing, Yang Hongfu, Li Weixan and Chen Hongyu when they described its only species Fivepearlus yunnanensis.[2] The type locality of F. yunnanensis was given as the River Nanpanjiang in Qiubei County of Yunnan.[3] This taxon is classified in the subfamily Labeoninae in the family Cyprinidae, within the order Cypriniformes.[2]
Etymology
editFivepearlus is a latinisation of the English words "five" and "pearl", a reference to the bead-like protuberances on the lower lip resembling a "string of beads". The specific name yunnanensis, refers to the type locality in Yunnan.[4]
Description
editFivepearlus is distinguished from the other taxa in the subfamily Labeoninae by the possession of five round protuberences along its lower lip, these resemble a string of beads. It also has a body which is covered in scales and 5 branched fin rays in the caudal fin. Other features onclude the dorsal fin being supported by 2 spines and 7 soft rays while the anal fin has 2 spines and 5 soft rays. The holotype had a total length of 63 mm (2.5 in).[3]
Distribution
editFivepearlus is known from its type locality, the Qingshuijiang bridge on the Nanpangjiang River in Qiubei county, Yunnan. The type specimens were retained in Heilongtan Reservoir of Shilin.[1]
