Etymology: Syncomistes: Greek, syn, symphysis = grown together + Greek, komistes, -ou = leader, driver (Ref. 45335); holsworthi: Named for Bill Holsworth whose foundation financed the expedition on which this species was discovered, as well as providing ongoing support for doctoral research into the ecology, management and natural history of Australian wildlife.
Eponymy: William Norton ‘Bill’ Holsworth is an Australian mammologist and philanthropist. He and his wife, Carol, founded the Holsworth Wildlife Research Endowment (1989) which financed the expedition on which this species was discovered. (Ref. 128868), visit book page.

Adults prefer to inhabit deeper and slow flowing areas of creeks and rivers, as well as still waters and billabongs while juveniles occur in shallow, still waters or occasionally in riffle habitat. Usually forms shoals in the middle of the water column around snags, sometimes with Syncomistes bonapartensis. Feeds mainly on filamentous algae that are scraped off rocks with specially modified teeth. Attains sexual maturity at 9.0-10.0 cm. Spawns during the wet season and appears to wait until a major flood event to spawn. Produces non-adhesive eggs that are large, about 3 mm (Ref. 119336).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01288 (0.00590 - 0.02812), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
