Pores Po3 situated beetwen setal rows J and Z, on the line connecting setae Z4-J5 located closer to the setae Z4. Pores Po4 lie on the line connecting the base of setae S4-Z 5. Setae J1-J5, Z1, Z2, Z5, S1-S3 and R1-R7 short and smooth. Setae J6, Z3-Z4 and S4 long and barbed with hyaline ending. Setae J6 the longest opisthonotal setae (63-76 µm).
