Near posterior margin of genital flab 204 relatively long setae. Length of P1-5: 26, 50, 37, 74, 36 ( Figure 4B). P2 medially with two pinnate setae. Length of I-leg-4-6: 76, 95, 136. I-leg-6 (and also II-leg-6) dorsally with relatively long setae in anterior half, ventrally with a group of long setae; I-leg-4 with three stout setae near anterior margin ( Figure 4C). Length of IV-leg-4-6: 118, 118, 94. Fourth leg segments relatively slender ( Figure 4D)
