Etymology: Matilebias: Named for Dr. Matias Pandolfi; combination of his nickname 'Mati' and Greek 'lebias'; paucisquama: Name from the Latin pauci, meaning few, and squama, meaning scales, in reference to the reduced number of scales around caudal peduncle.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Vertebre: 28 - 30. Distinguished from its congeners except from those of the Austrolebias alexandri species-group by the dark gray pectoral fins combined with the bright blue iridescence in males. Differs from other species of the Austrolebias alexandri species-group by fewer scales around caudal peduncle (12 vs. 16 or more) and the fewer dorsal-fin rays in males (17-21 vs. 20 or more ). Can be differentiated from all other species of the genus by the absence of contact organs on the inner surface of the pectoral fin in males and the color pattern of females - ground color light brownish, sides of body with a variable number of relatively large dark black spots distributed mostly on posterior portion of body (Ref. 76851).
Body shape (shape guide): elongated.
Inhabits temporary pool, almost completely covered with emergent vegetation (Ref. 76851).
