Etymology: Hemitriakis: hemi-, from hemisys (Gr.), half, being a genus that Herre believed was “most closely related” to Triakis. (See ETYFish); indroyonoi: In honor of Indroyono Soesilo (b. 1955), geologist, engineer and Chairman, Marine and Fisheries Research Agency (Jakarta, Indonesia), “who has provided a great deal of support for shark research in Indonesia and was a strong advocate for the production of the field guide to sharks and rays of Indonesia”. (See ETYFish).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00363 (0.00185 - 0.00711), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (72 of 100).
