Remarks. This is the first record of frenata from Japan. This species resembles latungula in the absence of an overhang and strip of minutely papillate cuticle on the mesal surface of the paramere, the membranous pad and the presence of teeth on the ventro-apical corner of the digitus, but can be distinguished from the latter by the characters in the key.
