簡単な記述 形態学 | 形態計測学

背鰭 (合計): 8-9; 臀鰭: 5 - 6; 脊つい: 28. Pseudotothyris janeirensis is distinguished from all congeners by possessing dorsal-fin spinelet (vs. absent); transverse dark saddles on the dorsum absent (vs. present); subocular cheek plate always absent (vs. generally present); and odontodes on lateral plates aligned in well-defined series (vs. randomly distributed). It can be diagnosed from Pseudotothyris obtusa by having abdomen almost entirely naked, except for one to three lateral abdominal plates and one to two preanal plates (vs. abdomen partially or totally covered by scattered plates); 31-35 teeth on upper pharyngeal toothplate (vs. 20-30); and 18-23 teeth on ceratobranchial 5 (vs. 12-15 ). It differs differs from Pseudotothyris ignota by having the anterior margin of snout completely covered by odontodes (vs. anterior margin of snout with an odontode-free band) (Ref. 116384).

生物学     用語集 (例 epibenthic)

Collected from a lentic environment, regionally known as açude, a kind of water reservoir. It is uncommon for Pseudotothyris and for the majority of the members of Hypoptopomatinae to occur in this type of habitat (Ref. 116384).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00646 - 0.06755), b=3.03 (2.78 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
