Postero-ventral seams between T3/T4 curved anteriorly, so that segments are markedly longer dorsally than ventrally. Posterior seam of T5 projected posteriorly and ventrally. Microtrichosity of the abdomen laterally grey and golden. ST1+3 with yellow or light brown hair-like setae. One lateral setae on each side of T4. T5 with golden microtrichosity.
