All the abdominal tergal setae are broadly pointed apically. The abdominal plaques segments II–VII with few poorly developed or rounded microtrichia anterior of the dorsal setae; those on VIII are more abundant. Sometimes a few pointed microtrichia present on tergite VIII. Tergite IX with a darkened band in which the anterior margin extends anteriorly about the diameter of a D1 setal socket. The posteromarginal teeth tergite IX are about the same length as the basal width of the D1 setae; approximately 18–21 teeth present between the D2 setae. The ventral posteromarginal teeth are minute about 1/2 the size of the dorsal teeth. Tergite X with a transverse dark band that extends to the campaniform sensilla of the tergite.
