Abstract:
A new blind loach species, Triplophysa erythraea sp. nov.,
from a karst cave in Hunan Province, central south China, is
described based on morphology and cyt b gene sequencing. It
can be distinguished from other species of Triplophysa by the
following combination of characters: eyes absent; body
scaleless and colorless; caudal-fin 17; maxillary barbel
longest; fins transparent, compressed pectoral-fin reaching 2/
3 distance between pectoral-fin and pelvic-fin origins; pelvicfin
and dorsal-fin origins relative; posterior chamber of
airbladder well developed, long, oval, and dissociative.
Blindfish possess distinctly degenerated or completely lost
eyes due to their cave or subterranean water system or deep
ocean habitats (Zhao & Zhang, 2009). These specialized fish
species are found within Cypriniformes, mostly belonging to
Sinocyclocheilus or Triplophysa, and inhabit various inland
river systems in China (Zhang & Dai, 2010). The genus
Triplophysa (Nemacheilidae, Cypriniformes) is comprised of
small fish living in streams and primarily distributed in the
Tibetan Plateau and adjacent areas (He et al., 2011;
Jacobsen et al., 2017; Xiao & Dai, 2011). A total of 202
species have been reported within the genus (Eschmeyer et
al., 2018), including a number of cave-dwelling species (or
populations) specialized for living in underground
environments (Lan et al., 2013; Li et al., 2008; Yan, 2017). So
far, a total of 30 cave-dwelling species of Triplophysa are
known to occur in China (Li et al., 2017, 2018; Wu et al., 2018;
Yan, 2017), of which 27 species have been identified from
Yunnan, Guizhou, and Guangxi, and two from Chongqing (T.
rosa) and Hunan (T. xiangxiensis) (Lan et al., 2013; Li et al.,
2017; Wu et al., 2018; Yan, 2017; Zhang & Zhao, 2016
