Etymology: Pseudotothyris: Greek, pseudes = false + Greek, ous, otis = ear + Greek, thyris, -idos = little door (Ref. 45335);  ignota: Derived from the Latin ignotus, meaning unknown or ignored, because this species has been identified as Pseudotothyris obtusa since the description of the older species in 1911..

Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 8 - 9; Rayons mous anaux: 6; Vertèbres: 28 - 29. Pseudotothyris ignota is distinguished from all congeners by possessing the anterior margin of snout with an odontode-free band (vs. anterior margin of snout completely covered by odontodes). It can be further differentiated from Pseudotothyris obtusa by having 32-47 teeth on the upper pharyngeal toothplate (vs. 20-30); 15-31 teeth on ceratobranchial 5 (vs. 12-15); first anal-fin pterygiophore contacting the 13th vertebra (vs. 12th); and metapterygoid-hyomandibula suture complete, the bones contacting each other dorsally to the suture (vs. metapterygoid-hyomandibula suture reduced, the bones not contacting each other dorsally to the suture. It can be further distinguished from Pseudotothyris janeirensis by the presence of three transverse dark saddles on the dorsum (vs. absence); absence of spinelet (vs. presence); generally presence of subocular cheek plate (vs. always absence); and odontodes on lateral plates randomly distributed (vs. odontodes aligned in well-defined series) (Ref. 116384).

Biologie     Glossaire (ex. epibenthic)

Inhabits coastal drainages from Iguape in São Paulo state to São João do Rio Vermelho in Santa Catarina state, Brazil. Occurs sympatrically with Pseudotothyris obtusa in small coastal drainages in Iguape, Cananéia, and Ilha Comprida, which are adjacent to Ribeira de Iguape basin (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=0.00759 (0.00337 - 0.01709), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  2.4   ±0.1 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
