Remarks
- Systematics: Pinnaspis yamamotoi is similar to P. hikosana in that the 2nd lobes are much reduced in size, but it is distinguished by having more numerous submarginal dorsal macroducts (Takagi, 1965a).
- Structure: Female scale brown. Adult female fusiform, robust. Median lobes prominent, closely appressed mesally, notched 3 or 4 times laterally, with median basal zygosis much protruding anteriorly beyond their bases. 2nd lobes much reduced, yet somewhat variable in size; inner lobule with basal paraphyses rudimentary or practically obsolete. 3rd lobes reduced to marginal serrations (Takagi, 1965a).
- General Remarks: Detailed description and illustration by Takagi (1965a).
