Ornamentation consists of one spinule at base of dorsal seta, posterior ventral row of three small spinules and one dorsal cuticular pore. Dorsal seta inserted close to posterior medial margin, about 1.6 times as long as caudal ramus, triarticulate at its base and smooth. Proximal lateral seta arising somewhat dorsolaterally at midlength, 0.8 times as long as dorsal one and 1.6 times as long as distal lateral seta, which arises at 3/4 of ramus length. Inner apical seta slender, small, smooth, about 0.4 times as long as ramus. Both principal setae inserted slightly more dorsally than terminally, smooth and with breaking plane.
