swimming crabs (family Portunidae) are distributed worldwide and
commonly inhabit estuaries, mangroves, reefs, shallow and the deep sea.
Previously, 75 species and 19 genera in this family were known to
Taiwan. Our study examined specimens in Taiwanese waters, including
the islands, collected between 2016 and 2020 or deposited in museums.
Through the cytochrome oxidase subunit I DNA barcode marker and
morphological examination, 71 species were identified. The minimum
interspecific distances were greater than 4.09%, except in two
unresolved groups: Charybdis miles
(De Haan, 1835) and Ch. sagamiensis
Parisi, 1916, as well as Thranita
pelsarti (Montgomery, 1931) and Thr. prymna (Herbst, 1803). In
addition, 14 species belonging to nine genera were confirmed as new
records to Taiwan, viz. Carupa
ohashii Takeda, 1993, Lupocyclus
inaequalis (Walker, 1887), Luu.
tugelae Barnard, 1950, Lupocycloporus
minutus (Shen, 1937), Monomia
gladiator (Fabricius, 1798),
M. lucida Koch & Ďuriš, 2018, Podophthalmus minabensis Sakai,
1961, Thalamita gatavakensis
Nobili, 1906, Tha. spinifera
Borradaile, 1902, Thalamitoides
quadridens A. Milne-Edwards, 1869, Tho. tridens A. Milne-Edwards,
1869, Thr. cerasma (Wee &
Ng, 1995), Thr. coeruleipes
(Hombron & Jacquinot, 1846) and Xiphonectes
tuberculosus (A. Milne-Edwards, 1861). This study thus raises
the total number of Portunidae species in Taiwan to 89.
