Cw. Lin et Ty. Chan, First record of the deep-sea shrimp genus Ephyrina Smith, 1885 (Decapoda, Oplophoridae) from Taiwan, with the description of a new subspecies, CRUSTACEANA, 74, 2001, pp. 183-192
The deep-sea genus Ephyrina Smith, 1885, is reported for the first time fro
m Taiwan. The specimens obtained all belong to one species. The Taiwanese m
aterial closely resembles E. figueirai Crosnier & Forest, 1973, in having d
ouble rows of lateral spines on each side of the telson, but consistently d
iffers from the nominotypical form from the Atlantic in having a longer and
more spinose telson, while also the dorsal depression on abdominal somite
VI is slightly more pronounced. Comparison of additional specimens from the
Philippines and from Madagascar shows that the West Pacific specimens are
nearly identical, but the Madagascan material seems to have characters inte
rmediate between the West Pacific and Atlantic forms. We decided to propose
a subspecific status to the West Pacific population, in order to emphasize
the slight but constant differences observed in the telson in this obvious
ly allopatric form of the species.
