Relevant Information:

Description: Similar to Glyptothorax laosensis. Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal soft rays: 8 - 9. Head and front of the body horizontally flat, gradually turns to vertically flat. Small eyes, covered with membrane. Nude body without scale, with a straight lateral line. Glyptothorax is distinguished from all other sisorid genera by having an adhesive apparatus on the thorax with with grooves parallel or oblique to the longitudinal axis of the body (vs. thoracic adhesive grooves transverse to the longitudinal axis of the body in Pseudecheneis, and thoracic adhesive apparatus absent in all other genera). Colouration: Three white lines in the body, one starts from dorsal fin to caudal fin, the other two overlapped with the lateral line. Brownish adiposium, dark in the base part and light in the edge. Etymology: The specific name pallozonus: pallidus (L.), pallid or pale; zonus, Neo-Latin adjective of zona (L.), band, referring to white band along lateral line. Remarks: the 2-5 thumbnail specimens by the image contributor were captured in the Pearl River or Zhu Jiang (Chinese).

IUCN Red List

This species is found in Lianhua Shan Mountain of Haifeng County and Dongjiang drainage in Guangdong Province, China. The population of this fish is unclear, and it is naturally very rare in Guangdong province, recent survey in Guangdong province from 2005-2009 did not record the species. The species has a relatively wide distribution however its population trends are unknown and it is suspected to have declined due to agro-chemical pollution, more information is needed as the species may be threatened. Therefore the species is assessed as Data Deficient, but needs updating, (IUCN 2011).
