|Types||Holotype: AMNH 119876|
|Diagnosis||DIAGNOSIS: Atractus depressiocellus is immediately distinguished from other Panamanian Atractus by its large size, relatively uniform dorsal pattern of irregularly paired black cross-lines on a brown ground, and very small eyes that are notably depressed on a broad, relatively short head. It is the only Panamanian Atractus in which head length (tip of snout to end of parietals) is equalled by head width. In total length, Atractus depressiocellus approaches A. obesus from Andean Colombia and the Amazonian A. major and A. torquatus. These differ from depressiocellus in color pattern (photographs in Marx, 1960; Martins and Oliveira, 1993) and in various features of scutellation. Atractus depressiocellus also differs noticeably from these in its very small depressed eye and in the associated feature of exceptionally tall supralabials 3–5. It may be unique in either lacking or in having exceptionally tiny internasals (from MYERS 2003).|
|Etymology||Named after the depressed, very small eyes, and hence the specific name, a noun in apposition, is derived from the Latin adjective depressus (low or depressed) and the noun ocellus (a little eye).|
