Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| 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. |
