Etymology: Platyurosternarchus: Greek, platys = flat + Greek,oura = tail + Greek, sternon = chest + Greek, aarchos = anus (Ref. 45335); crypticus: The specific epithet came from the Greek word, kryptos, meaning hidden or secret, refers to the previously undetected, albeit very distinct, differences between this species and its sole congener.

The type locality, Moco-Moco Creek, is a small stream with usually clear water but turns muddy for several hours after heavy rainfalls. One specimen was collected from a forest stream with relatively clear water weakly stained in tannins over a gravel and cobble bottom covered with leaf and twig litter. Reported to occur in rapids and streams and regarded as a predator, presumably preys on invertebrates (Ref. 81220).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
