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.
|H. Matsumoto 1915||Radial shield and genital plate articulate with each other by means of two condyles and one pit on either plate. Genital plates and scales bar-like. Peristomal plates small, or sometimes moderately large, usually double or triple. Oral frames with or without well-developed lateral wings. Oral papillae very well developed, close set, the outermost one usually pointing inwards and stretching above the next papilla, which is the largest as a rule.|
