Abstract

Six species of the family Kelleriidae, including four new species, are recorded from tropical waters of the Asia-Pacific, two of them from Phuket Island, Thailand, one each from Bohol Island, Philippines and Phu Quoc Island, Vietnam, and two from Kosrae Island, Micronesia. A new genus Kelleriella is proposed to accomodate one of these new species (Kelleriella quadridens n. sp.). There are three diagnostic features of the new genus: the terminal segment of antenna is armed with one strong claw and six setae, the armature of the maxilliped endopod is reduced, and the third exopodal segment of leg 4 is armed with four spines and five setae. The other three new species are Kelleria latipes n. sp., Kelleria phuketensis n. sp., and Kelleria robusta n. sp. As diagnostic features of these new species, their caudal rami are about 2.5, 3.2, and 1.72 times longer than wide, respectively, the exopod of leg 5 of them is smooth, without any process, about 1.9, 3.7, and 2.9 times longer than wide, respectively, and armed with one spine plus one seta in Kelleria latipes and Kelleria phuketensis or with 2 setae in Kelleria robusta. Additionally, Kelleria javaensis Mulyadi, 2009 is synonymized with Kelleria regalis Gurney, 1927 and Kelleria grandisetiger Kim, 2006 is synonymized with Kelleria andamanensis Sewell, 1949, and both species are redescribed.
