Teleostei (teleosts) > Cyprinodontiformes (Rivulines, killifishes and live bearers) > Poeciliidae (Poeciliids) > Poeciliinae
Etymology: Brachyrhaphis: Greek, brachys, eia = short + Greek, raphis = needle (Ref. 45335); roswithae: Named in honor of Roswitha Etzel, Cuxhaven (Ref. 42972).
Eponymy: Roswitha Erasmy née Etzel of Cuxhaven is, we believe, the daughter of the junior author; the late Dr Vollrad Max Friedrich Etzel (1944–2012) (q.v.). (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), 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): 3.3 ±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.).

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