A time-calibrated mitogenomic phylogeny suggests that Korean Hyalessa fuscata is a bridge between Chinese and Japanese H. maculaticollis
The cicada species, Hyalessa fuscata and H. maculaticollis (Hemiptera: Cicadidae), share numerous morphological characters, and their status as distinct species remains controversial. We reconstructed a phylogeny based on two new mitogenomes of H. fuscata from Korea and H. maculaticollis from Japan,...

Summary: | The cicada species,
Hyalessa fuscata
and
H. maculaticollis
(Hemiptera: Cicadidae), share numerous morphological characters, and their status as distinct species remains controversial. We reconstructed a phylogeny based on two new mitogenomes of
H. fuscata
from Korea and
H. maculaticollis
from Japan, in combination with GenBank sequences of
H. maculaticollis
from China and Japan, and other closely related cicada species. Maximum likelihood and Bayesian inference phylogenies showed that
H. fuscata
from Korea is more closely related to
H. maculaticollis
from China than either is to
H. maculaticollis
from Japan. The time-calibrated Bayesian evolutionary analysis by sampling trees (BEAST) phylogeny indicated that the mainland and insular forms diverged approximately 1.7–2.6 million years ago. This coincides with the formation of the East China Sea land bridge between East Asia and the Japanese archipelago, which would provide a dispersal corridor for
Hyalessa
from the mainland via the Korean peninsula southeastward to Japan. East Asian
H. fuscata
is a geographic variant that may be considered synonymous with
H. maculaticollis
