Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 13-15; Espinas anales 0; Radios blandos anales: 16 - 20. Diagnosis: Body slender, its depth 18-27% of standard length; pre-pelvic scutes not strongly keeled, beginning under or behind base of last pectoral finray, 7-10 pre-pelvic and 9-12 post-pelvic scutes, belly rounded; snout bluntly rounded; lower jaw not projecting, exactly meeting tip of upper when mouth closed, deepest at mid-point of jaw, with small saw-like teeth on each side; pre-maxillae with small teeth pointing downward; maxilla very slender, its blade over 3 times as long as deep, upper edge ridged, lower edge without denticulations; posterior supra-maxilla very small, spatulate, its shaft about as long as its blade; lower gillrakers 14-16; silver stripe on flank, narrower anteriorly (Ref. 188, 28136). It differs from Potamothrissa whiteheadi in having a distinct shaft to the posterior supra-maxilla and lacking dermal denticles on the snout, and from P. acutirostris in its blunt snout and fewer gillrakers, 14-16 vs. 16-18 (Ref. 188, 28136). Other pellonulines lack saw-like teeth at the sides of the lower jaw (Ref. 188).

Biología     Glosario (por ej. epibenthic)

Found in rivers and streams (Ref. 41580), perhaps not in lakes (Ref. 188). It feeds on aquatic insects and also hydracarians (Ref. 188, 41580).
