Derm of older adults rather uniformly sclerotised, with a fairly broad band of elongate areolations close to margin, the long axis of each areolation parallel with margin; inner submargin with small oval areolations, these absent or indistinct submedially and medially; rest of derm apparently without abundant minute pale spots. Stigmatic rays present; marginal radial lines obscure, indicated by lines of pores and setae, with 13 lines on head between anterior stigmatic clefts, and each side with 5 between stigmatic clefts and 13 on abdomen. With 4 pairs of abdominal clear areas but none associated with apex of anterior stigmatic rays. Dorsal setae quite long and spinose, each with parallel sides and a pointed apex, 1618 µm long, frequent in a sparse polygonal pattern submarginally but absent submedially and medially. Preopercular pores mostly each 45 µm wide, distributed as follows: CA1 with 512 pores, CA2 with 1016, CA3 with 1521 and CA4 with 02 pores. Other dorsal pores all small, possibly in a polygonal pattern, of 2 sizes: a minute pore (appearing as a clear spot) about 1 µm wide, and a slightly larger clear spot, each about 3 µm wide with a dark pore, perhaps a dorsal microduct; both pore

Anal plates rather small and together almost square, outer angle almost a right-angle, with anterior and posterior margins subequal in length; each plate with 4 minute setae near posterior apex plus 1 or 2 small pores medially; length of plates 2 00210 µm, combined width 170185 µm. Anogenital fold with 35 minute setae at each corner of anterior margin, each lateral margin with a seta anteriorly and another at posterior end.
