Remarks. Primno latreillei Stebbing, 1888 is one of the smaller species within the genus Primno and is morphologically similar to P. johnsoni Bowman, 1978 . Primno johnsoni was considered a junior synonym of P. latreillei by Vinogradov et al. (1982) and Zeidler examined specimens among those identified as P. johnsoni in the Australia ( Zeidler, 1992; 1998). Within the morphological range of P. johnsoni, Zeidler synonymized the specimens with P. latreillei ( Zeidler, 2004) . Stebbing attached the most importance to the morphology of pereopods 5 and 7 in P. latreillei . These two species are morphologically similar in the following features: (1) pereopod 5 carpus, length of elongate teeth on anterior margin subequal to width of carpus; (2) pereopod 5 carpus, row of teeth on anterior margin with one of the elongate teeth proximally ( Bowman, 1978; Zeidler, 2004). However, P. latreillei is distinguished from P. johnsoni (different characters of P. johnsoni in brackets) by the following features: (1) gnathopod 1, propodus without robust seta (vs. with 2 robust setae medially), (2) pereopod 7, basis length more than 1.5 times length of following articles combined (vs. basis length about 1.2 times length of following articles combined), and (3) uropod 3 with well-developed apical notch (vs. without apical notch). Our Korean specimens are in good agreement with the description of Bowman (1978).
