Etymology: Eusurculus: Name from Latin and Greek 'eu' for good or real and Latin 'surculus' for grapevine tendril, refers to the functional analogy with the pseudoclaspers and the specific shape of the inner pseudoclasper; pristinus: Name from Latin 'pristinus' for ancient or original, refers to the simpler pattern of the inner pseudoclasper when compared to the sucker-disk of E. andamanensis and E. pistillum; noun in apposition.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
