Stylodactylidae and Bathypalaemonellidae (Crustacea : Decapoda : Caridea) from the PANGLAO 2004 and 2005 expeditions to the Philippines, with description of a new species of Stylodactylus A. Milne-Edwards, 1881

Five species of the family Stylodactylidae Bate, 1888 and two species of Bathypalaemonellidae de Saint Laurent, 1985, were collected by the PANGLAO 2004 and 2005 expeditions to the Philippines. A member of the Stylodactylidae, Stylodactylus gracilis new species, collected at 2149-2217 m, is described and illustrated. The new species is distinguished from the 15 described species of Stylodactylus by a very thin and glabrous integument; a very long ( 0.8 times of carapace length) antennular peduncle, by the lengthening of the second segment ( 1.8 times longer than first); thin and very long third to fifth pereopods, as a result of the lengthening of the meri and propodi. The two species of Bathypalaemonellidae, Bathypalaemonella aff. hayashii Komai, 1995, and Bathypalaemonetes brevirostris ( Bruce, 1986), represent new records for the Philippines.
