 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Acestridium triplax Rodriguez & Reis, 2007 |
| Common Name(s) | None |
| Type Locality | Brazil, Pará, Município de Juruti, igarapé Mutum, tributary to rio Aruã, a tributary to rio Branco, a tributary to rio Aripiuns, itself a tributary to the lower rio Tapajós, 2º36’45 |
| Etymology | The species epithet triplax from the Greek tri, three, and plax, plate, referring to the three series of abdominal plates present in the new species. |
| Species Information | |
| Size | 56mm (2.2") SL. Find near, nearer or same sized spp. |
| Identification | Acestridium was diagnosed by Schaefer (1991) based on the following characters: ten principal caudal-fin rays; plates at anterior snout margin forming conspicuous spatulate projection; head and body very slender, depressed; dorsal surface of head and trunk with longitudinal ridges; dorsal fin placed posteriorly, well beyond pelvic fin and just anterior to anal-fin origin; adipose fin absent; dermal plates anterior to first dorsal-fin proximal radial expanded, bearing ventromedial keel contacting the dorsal margin of the neural arches of the vertebrae six through twelve; and ridge of bone on the ventral surface of the lateral ethmoid contacting the metapterygoid channel reflected mesially. A. triplax can be distinguished from all its congeners by having one series of middle abdominal plates between the lateral abdominal plates (vs no abdominal plates between the lateral abdominal plates). |
| Sexing | Males of Acestridium triplax have conspicuous urogenital papilla, immediately posterior to anal opening, these are not present in females. |
