Material examined.
Republic Of Korea ∙ 1 ♀ (MABIK CR00246555) was dissected on 13 slides ∙ 1 ♂ (MABIK CR00246552) was dissected on 9 slides ∙ 11 ♀♀ (MABIK CR00246553, CR00246554, CR00246556 to CR00246560, CR00246562 to CR00246565) and 1 ♂ (MABIK CR00246561) were preserved in 99 % alcohol ∙ GenBank accession numbers: MN996282 to MN996293 (
COI
) and MT002906 to MT002909 (

), see also

Note.
Chang and Song (1997)
reported that
P. verrucosa
collected from Korea differed from
Ito's
description in regards to three characteristics (length of caudal rami, segmentation of A2 exp, and presence of rows of spines along posteroventral margin), and the specimens analyzed in the present study also varied in this manner. In particular, the base of the second lateral seta of the A2 exp was protruding and could be seen as two segments, depending on the angle. In addition, the male specimens analyzed in the present study also differed from
Ito's
original description in regards to A1 segmentation. More specifically, the A1 of
Ito's
specimen possessed a small seg-3 and swollen seg-4, whereas that of the present
study's
specimens possessed small seg-3 and seg-4 and a swollen seg-5.
