PUPAE ‒ Cephalothorax and abdomen with darkly pigmented areas; seta 1-I strongly developed, dendritic; seta 2-II inserted lateral to seta 1, 2-III‒VII inserted anterior to setae 1 (at approximately mid-length of terga IV‒VI); seta 3-II inserted lateral and 3-III‒VI inserted anterior to seta 1; seta 6-II single, long, longer than following tergum, seta 6-VII inserted on tergum posteromesal to seta 9; paddle long, much longer than tergum VIII, gradually narrowed to apex, apex and lateral margins with minute spicules.
