This
is the first taxonomic study of Collembola in Taiwan integrating
morphological and molecular evidence to investigate the Taiwanese
species in the genus Ptenothrix
Börner. We discovered that specimens previously identified as Ptenothrix denticulata (Folsom,
1899) actually consist of several cryptic species, of which we
described two species new to science. Our data revealed that, although
these species are remarkably similar to each other, they can be
distinguished by color patterns, chaetotaxic characters and DNA
barcoding (COI). We also
designated one of the syntypes of Ptenothrix
denticulata (Folsom, 1899) as its lectotype, and treated Dicyrtoma denticulata (Salmon 1964)
as a synonym of Ptenothrix
denticulata (Salmon 1964) (syn. nov.). Lastly, our study
suggests that the diversity of Collembola in Taiwan is still poorly
understood, with a high potential for new studies focusing on these
microarthropods.
