Dorsal macrochaetae shown as in Fig. 90 . Th. II with 2 (m1, m2) macrochaetae in Mm area and 2 (m4, a5) macrochaetae in Ms area. Th. III with 3 (a1, a2, a3) macrochaetae in Am area and 5 (a 4i, a4, a5, m 5i, m5) macrochaetae in As area.

Abd. IV 3.6−4.2 times as long as Abd. III along dorsal midline. Abd. I with 3 (m2, m3, m4) macrochaetae. Abd. II with 3 (a2, m3, m3e) central and 1 lateral (m5) macrochaeta, Abd. III with 1 central (m3) and 3 lateral (am6, pm6, p6) macrochaetae ( Fig. 91 ). Central part of Abd. IV with 7+7 macrochaetae ( Fig. 92 ). Abd. V with about 9 macrochaetae and 3 sensory chaetae ( Fig. 93 ). Manubrial plaque with 3 ciliate chaetae and 2 pseudopores ( Fig. 94 ). Mucro falcate and tip of basal spine not reaching apex of apical tooth ( Fig. 95 ).
