Zhao, Hai-Tao, Sullivan, John P., Zhang, Yao-Guang & Peng, Zuo-Gang, 2014, Paraqianlabeo lineatus, a new genus and species of labeonine fishes (Teleostei: Cyprinidae) from South China, Zootaxa 3841 (2), pp. 257-270 : 259-260

Paraqianlabeo , new genus

Type species: Paraqianlabeo lineatus , new species ( Figs. 2 , 4 )

Diagnosis. Paraqianlabeo can be distinguished from all other genera of the Garraina (sensu Stiassny & Getahun 2007) by its uniquely modified oromandibular morphology; i.e., arched, wide, rudimentary sucker formed by raised front and lateral margins of lower lip, postlabial groove and mental groove between middle and lateral lobes of lower lip chevron-shaped ( Fig. 2 ). The genus is further distinguished by having a unique combination of the following characters: anteroventral margin of rostral cap arched, thin and papillose; rostral cap not overlying upper lip, upper lip connected with lower lip around corners of mouth; well developed upper lip free from upper jaw; lower lip divided into two lateral fleshy lobes and one central plate, these two lateral fleshy lobes small and short, median lobe of lower lip large; anterior and anterolateral edges of upper and lower lip finely papillose; shallow, straight groove between lower lip and lower jaw; lower jaw bearing thin, cornified cutting edge; scales in ventral medial region from pectoral fins to pelvic fins half-hidden and subcutaneous; 3 scale rows below lateral line; 7½-8 branched dorsal-fin rays.

Etymology. The generic name is from a combination of the Latin word Para (beside; beyond or outside; associated with) and Qian (abbreviation for Guizhou Province), where the type species was collected, and the Latin word Labeo , a generic name and commonly utilized suffix for Labeoninae genera. Gender: masculine.
