Comparative diagnosis.

General appearance, colouration, antennal structure, and male and female terminalia are very similar to C. distinctissima . Differences: only the ventral margin of the inner gonocoxal lobe are sclerotised (Fig. 6N View Figure 6 ) (the lateral margin is also sclerotised in C. distinctissima (Fig. 6D, E View Figure 6 ). Sheath of aedeagus shorter and wider (Fig. 6P View Figure 6 ) than in C. distinctissima (Fig. 6L, M View Figure 6 ). Aedeagus does not narrow to the tip in this species, the lateral margin being almost straight (Fig. 6P View Figure 6 ) (in C. distinctissima the aedeagus clearly narrows to the tip, starting from around the middle in Japanese specimens (Fig. 6M View Figure 6 ). Spermathecae small (Fig. 7K View Figure 7 ), diameter ~ 0.07-0.1 of the width of sternite 8 (in C. distinctissima relatively large, 0.15-0.2 of the width of sternite 8).

For a detailed species description see Brodo (1967) under " Cylindrotoma distinctissima americana ".
