Etymology: Glyptothorax: Greek, glyptes = carver + Greek, thorax = breast (Ref. 45335);  ketambe: This species is named after its type locality, the Ketambe research station, which is world renowned as a site for the study of the Sumatran orangutan (Pongo abelii). Used as a noun in apposition..

Description synthétique Clés d'identification | Morphologie | Morphométrie

Glyptothorax ketambe can be distinguished from all other Sundaic congeners except G. schmidti and G. siamensis in having a color pattern consisting of a dark brown body with yellowish midlateral and mid-dorsal stripes. It differs from G. schmidti in having a deeper caudal peduncle (7.6–8.9% SL vs. 5.8–7.3) and a less posteriorly-extended thoracic adhesive apparatus (not reaching vs. reaching to the level ofthe base of the last pectoral-fin ray) and from G. siamensis in having a narrower head (16.1–17.9% SL vs. 17.2–20.1) and an almost straight (vs. noticeably curved) lateral margin of the thoracic adhesive apparatus. There are eight other congeners from mainland Southeast Asia that share a similar color pattern of a dark-colored body (with or without distinct pale midlateral and mid-dorsal stripes) with G. ketambe: G. coracinus, G. interspinalus, G. laosensis, G. longicauda, G. longjiangensis, G. strabonis, G. trilineatus and G. zanaensis. Glyptothorax ketambe is distinguished from G. coracinus in having a wider interorbital distance (29.0–31.2% HL vs. 26.2–26.7), from G. interspinalus in having a deeper caudal peduncle (7.6–8.9% SL vs. 6.1–8.0) and a narrower head (16.1–17.9% SL vs. 17.2–22.1), from G. laosensis in having a narrower head (16.1–17.9% SL vs. 19.2–21.1) and a less posteriorly-extended thoracic adhesive apparatus (not reaching vs. reaching beyond the level of the base of the last pectoral-fin ray), and from G. longicauda in having a shorter caudal peduncle (20.1–22.9% SL vs. 23.6) and fewer vertebrae (37–38 vs. 42). It differs from G. longjiangensis in having tubercles on the dorsal surface of the head with a single, median ridge (vs. with anastomosing tubercles with multiple ridges) and without any pale markings on the nuchal plate (vs. part or all of the nuchal plate pale-colored), from G. strabonis in having a larger eye (7.5–9.6% HL vs. 6.2–6.5), interorbital distance (29.0–31.2% HL vs. 26.0–27.2) and fewer serrations on the posterior margin of the pectoral spine (9–12 vs. 14–16), from G. trilineatus in having a longer caudal peduncle (20.1–22.9% SL vs. 16.7–18.4), and from G. zainaensis in having a shorter adipose-fin base (12.0–14.5% SL vs. 14.4–18.4), and a less posteriorly-extended thoracic adhesive apparatus (not reaching to the level of the base of the last pectoralfin ray vs. reaching beyond) (Ref. 80807).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00371 - 0.01783), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
