Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Siluriformes (Catfishes) > Loricariidae (Armored catfishes) > Hypostominae
Etymology: Paulasquama: Name from the Latin ‘paulus’ for small, and ‘squama’ for scale armor, referring to the small plates located in the dorsal series just below the dorsal fin.;  callis: Name from Latin 'Callis' (masculine or feminine) for a stony, uneven, narrow footway, referring to the plates like cobblestones along the narrow mesethmoid with naked areas to either side; noun in apposition..

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic. Tropical

South America: NW Guyana (Waruma River, tributary of the Mazaruni River).

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 4 - ? cm
Max length : 4.7 cm SL male/unsexed; (Ref. 86603)

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal soft rays: 5. This species is distinguished from all other hypostomines by three unique autapomorphies: large, oval area lateral to the mesethmoid that is devoid of plates; plates in the dorsal series lateral to dorsal fin reduced to less than half what would be expected for a loricariid of its size; and, a fleshy keel along and slightly anterior to the preadipose plate and extending to dorsal caudal-fin simple ray along dorsal procurrent rays (Ref. 86603).

Biology     Glossary (e.g. epibenthic)

The collection area Waruma is a largely clearwater river with a slight black tint. Specimens collected in a riffle, in a shallow side channel over polished cobble and gravel with some larger rocks covered in a grasslike vegetation. The watershed is forested (Ref. 86603).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), 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).
