Etymology: Alfaro: Taken from Anastasio Alfaro zoologist of the Natural Museum of Costa Rica.
Eponymy: Don Anastasio Alfaro (1865–1951) was an archaeologist, geologist, ethnologist, zoologist and famous Costa Rican writer. [...] Wharton Huber (1877–1942) was a collecting naturalist and zoologist who was at the Academy of Natural Sciences of Philadelphia (1920–1940), becoming Curator of Mammals (1923).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00454 - 0.02306), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Assuming tm < 1).

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

Price category (Ref. 80766): Unknown.
