Fishes of Mainland Southeast Asia (1) Beta Mahatvaraj (3) Arnob Bora (2)

Description: Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal spines: 12; Anal soft rays: 13; Vertebrae: 37. Distinguished from other species of Glyptothorax in the Indian subcontinent except for G. ater, G. brevipinnis, G. churamanii, G. jayarami, G. nelsoni, G. pantherinus, G. pectinopterus, G. radiolus and G. saisii in having (vs. lacking) a prominently plicate ventral surface of the pectoral-fin spine and the first pelvic-fin ray. Can be separated from G. ater, G. brevipinnis, G. churamanii, G. jayarami, G. nelsoni, G. pantherinus, G. pectinopterus, G. radiolus and G. saisii in having the following combination of characters: snout length 51.8-54.7% HL, wedge-shaped central depression in thoracic adhesive apparatus devoid of skin ridges, pectoral-fin length 18.7-23.8% SL, plicae on ventral surfaces of pectoral-fin spine continuous, dorsal-fin spine length 10.3-15.7% SL, dorsal-to adipose distance 24.9-27.9% SL, body depth at anus 11.0-14.7% SL, adipose-fin base length 10.7-13.5% SL, caudal-peduncle length 18.4-20.7% SL, caudal-peduncle depth 6.8-8.6% SL (1.6-1.9 times in body depth at anus), and distinct pale midlateral stripe on body. Habitat: Inhabits mountain rapids. Etymology: The specific name striatus: Latin for furrowed or grooved, referring to “striated sucker on the breast”. Remarks: Glyptothorax striatus was described from the Khasi Hills in Meghalaya, India, and is present in the Meghna and Brahmaputra river drainages in India and probably in Bangladesh. Logging, deforestation and mining activities in Khasi Hills threaten the species' habitat and population. Since the range is just over 20,000 km2, this species misses qualifying for Vulnerable category. It is hence assessed as Near Threatened (IUCN).
