Abstract

This study reports the first record of the genera Paralobella Cassagnau & Deharveng, 1984 and Blasconura Cassagnau, 1983, three new species from Kuchinoerabu-jima and Miyako-jima of Japan, respectively. Paralobella kuchierabu sp. nov. can be distinguished from all known genus members by distinct morphological characteristics: yellow body color, mandible with 3 teeth, presence of chaeta O on head, and tubercle De of Th. II–III with 5 (4+s) chaetae, tubercle Di of Th. I with 1 chaeta, tubercles De and Dl of Abd. V separated. Blasconura triangulum sp. nov. is characterized by a tubercle Fr fused to An, unguis without an inner tooth, and 2 very closely placed tubercles Di on head. Blasconura cordis sp. nov. is unique in the genus, with a tubercle An fused to Cl. Other characteristic features of the species are the absence of chaeta O on head, tubercle Oc with 3 chaetae, Ant. I with 7 chaetae, and tubercle De of Th. III with 5 (4+s) chaetae. A key to all species of the genus Paralobella and Blasconura is provided.
