Scientific Name	**Corydoras (lineage 8 sub-clade 4) ambiacus** Cope, 1872
Common Names	Spotted Corydoras Langsnudet Kravepansermalle (Denmark), Panzerwels (Germany)
Type Locality	Río Ambyiacu, Peru.
Synonym(s)	Corydoras grafi, Corydoras longirostris

Etymology	Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. Named for the Rio Ampiyacu in Peru, where the specimen was originally found.
Species Information
Size	49mm or 1.9" SL. Find near, nearer or same sized spp.
Identification	This species was described in 1872 with no picture or drawing and a couple of paragraphs of text. The author notes, "Straw color, with numerous indefinite brown spots on the sides. Dorsal fin with a large black spot covering anterior half, which also expands on the dorsal region round the base of the fin. Four vertical brown bands on caudal fin; anal spotted. Cheeks with blue reflections". In short, it should have no black marking in the top half of the dorsal fin and in particular the dorsal fin spine. Otherwise very similar to Corydoras agassizi.
