Bodotria furugelmiensis sp. nov. ( Figs. 3 , 4 )

Material examined

Holotype, ZIN­1/88380, female 6.0 mm, with empty marsupium, Sea of Japan, Peter the Great Bay, near Furugelm Island, 31 Jul 1998, 16 m, dredge . Paratype: ZIN­1/88381, 1 female 5.7 mm, Sea of Japan, Peter the Great Bay, near Large Pelis Island, 7 Aug 1986, 20 m, from silted sand, qualitative collection .

Diagnosis

Integument well calcified. Carapace sculpture reticulate, with numerous pits. Carapace, thoracic and abdominal somites with mid­dorsal carina. Carapace 2.8 times longer than first thoracic somite. Basis of first pereopod 4 times longer than carpus. E ndopod of uropod 1­segmented, with six spinous setae on inner edge; and one large, thick spinous seta dorsally.

Description

Holotype ( Fig. 3A ). Integument well calcified. Carapace ( Fig. 3C ) sculpture reticulate, each “cell” of reticulation with pit. In dorsal view, carapace elongated, subrectangular. Carapace shorter than one­third of total body length. Carapace, thoracic and abdominal somites with mid­dorsal carina. Mid­dorsal carina well developed on carapace, thoracic somites, first five abdominal somites, and on anterior half of sixth abdominal somite. Lateral surface with two well­developed carinae running from anterior edge of carapace to end of thoracic somites and onto first abdominal somite. Pseudorostrum short and truncated. Antennal notch angularly concave, with subacute antero­lateral angle.

Maxilliped III ( Fig. 3B ) with weakly curved basis, propodus and dactylus equal length.

Pereopod I ( Fig. 4A ) slender, basis elongated and four times longer than carpus; carpus widened with several setae along lower edge.

Pereopod II ( Fig. 4B ) 6­segmented, almost half length of pereopod I; dactylus with three spinous dorsal setae and one small seta in middle of outer edge; carpus with two spinous setae on outer distal corner.

Pereopod III ( Fig. 4C ) with elongated basis, five times longer than carpus; carpus and merus of equal length.

Uropod ( Fig. 4D ) more than twice as long as last abdominal somite; uropodal peduncle 1.5 times longer than last abdominal somite; exopod slightly longer than endopod, with two slender distal setae (long and short ones), and several slender setae along inner edge; endopod 1­segmented, with six spinous setae on inner edge; and one large thick spinous seta dorsally.

Males are not known.

Etymology The new species is named for the Island near where the species was found—Furugelm Island, which is a part of the Far­Eastern State Marine Biosphere Reserve.

Remarks The new species, Bodotria furugelmiensis , is very close to B. carinata Gamo, 1964 , from Sagami Bay.
