If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

M. Romano 1980(Modified from Hammann, 1974, p. 106.) Species of Eccoptochile with glabel la strongly convex, anterior lobe descending almost vertically to preglabellar field. Frontal area relatively narrow (sag.); anterior border steeply upturned forming an angle with lateral borders of free cheeks (viewed dorsally). Eyes start approximately level with S2 and reach back to St. Fixed cheeks narrow (sag.). Anterior thoracic segments pointed, becoming gradually more rounded posteriorly. Internal surface of exoskeleton smooth except for pits on cheeks
