摘要：

A new genus and species of the family Acanthochitonidae is described from tropical waters of the West Pacific. The new genus, unlike the other genera of the family, has 5 tegmentum areas (jugal, 2 pleural and 2 lateral) on the intermediate valves, vs. 3 areas (jugal and 2 pleurolateral), a common state in the family. In addition, the new genus has grooves with narrow partitions in the pleural areas. It also lacks pustules typical of the other genera of the family. Besides this, the new genus is characterized by significantly thickened cusps of major lateral teeth of the radula, which are divided with grooves. Lastly, the genus has only 3 gills on each side. Comparisons are made between the structure of the tegmentum of the new genus and two other genera, Bassethulha and Pseudotonicia, that also have grooves.
