Etymology: Thryssocypris: Greek, thrissa, -es = shad + Greek, Kypris, other name for Aphrodite, proceeding from Cyprus (Kypris), Greek, kyprinos = carp (Ref. 45335); smaragdinus: Specific epithet from the Greek smaragdinos which means emerald green (Ref. 31464). More on authors: Roberts & Kottelat.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Asia: western Borneo, Indonesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.4 cm SL male/unsexed; (Ref. 7050)
soft rays: 12 - 14;
Vertebrae: 38 - 39. Most readily distinguished from its only congener, T. tonlesapensis, by much larger head, larger eye, larger pharyngeal bone and fewer anal fin rays, scales and vertebrae. Anal fin origin on a vertical with dorsal fin origin (versus anal fin origin far in advance of dorsal fin origin in T. tonlesapensis). Snout tip projects strongly beyond upper jaw, thus differing strikingly from T. tonlesapensis, in which it projects but very slightly. However, in one paratype of T. smaragdinus, the snout tip projects little more than in T. tonlesapensis.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00270 - 0.01228), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
