Etymology: Glyptothorax: Greek, glyptes = carver + Greek, thorax = breast (Ref. 45335); maceriatus: From the Latin adjective maceriatus (masculine), meaning enclosed or walled in, in reference to the narrowly elliptic central depression in the thoracic adhesive apparatus being almost completely enclosed by skin ridges..

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 1; Rückenflossenweichstrahlen (insgesamt) : 6; Afterflossenweichstrahlen: 11 - 13; Wirbelzahl: 35 - 37. It is distinguished from other species of Glyptothorax from rivers draining the Ganges Delta in having a combination of the following characters: nasal barbel not reaching anterior orbita margin; interorbital distance 27.0-31.4% HL; head length 23.7-25.3% SL; head depth 12.5-14.2 % SL; thoracic adhesive apparatus with narrow elliptic central depression that is almost wholly enclosed posteriorly by skin ridges (striae) and with single, non-diverging series of striae running along its edges; width of adhesive apparatus 55.8-72.1% its length; unculiferous ridges of adhesive apparatus not extending anteriorly onto gular region; absence of striae on first pectoral- and pelvic-fin elements; pectoral-fin length 20.7-24.9% SL; smooth posterior
edge of dorsal spine; dorsal-to-adipose distance 17.8-23.6% SL; body depth at anus 11.3-13.8% SL; pelvic-fin length 15.9-19.1% SL; length of anal-fin base 13.9-16.2% SL; caudal peduncle length 21.4-23.9% SL; and caudal peduncle depth 6.4-7.6% SL (3.1-3.4 times in its length). In addition to these characters, it differs from congeners in the Kaladan River drainage in eastern Mizoram by its dorsal-spine length 13.0-17.1% SL (Ref. 91243).
Inhabits clear, shallow, moderately flowing streams with a predominantly sandy bottom. Lives in association with Garra spp. (Cyprinidae), Balitora cf. brucei (Balitoridae), Botia cf. almorhae (Botiidae), Lepidocephalichthys sp. (Cobitidae), Schistura spp. (Nemacheilidae), Amblyceps laticeps (Amblycipitidae), Glyptothorax botius (Sisoridae), G. telchitta (Sisoridae), and Channa sp. (Channidae) (Ref. 91243).
