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. IIIII 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.
本研究报告了日本奄美大岛和宫古岛的 Par alobella Cassagnau Deharveng, 1984 和 Blasconura Cassagnau, 1983 两个属的三个新种，这是首次记录。Paralobella kuchierabu sp. nov. 可通过其独特的形态特征与所有已知属成员区分开来：黄色的身体颜色、具 3 个齿的下颚、头部存在 O 刚毛以及 Th. IIIII 的 D e 结节有 5 根（4+s）刚毛、Th. I 的 D i 结节有 1 根刚毛、腹部 V 的 D e 和 D l 结节分离。Blasconura triangulum sp. nov. 的特征是 Fr 结节与 An 融合、爪无内齿以及头部有 2 个非常接近的 D i 结节。Blasconura cordis sp. nov. 在属中是独特的，具有融合的 An 结节和 Cl 结节。该物种的其他特征还包括头部无 O 刚毛、Oc 结节有 3 根刚毛、Ant. I 有 7 根刚毛以及 Th. III 的 D e 结节有 5 根（4+s）刚毛。提供了 Par alobella 和 Blasconura 属所有种的鉴别特征。
