Pygofer dorsoapical margin incised nearly to base, macrosetae absent or reduced (<= two rows) or macrosetae well differentiated into several rows, without dense tufts of thick or fine setae, without ventral tooth, spine, or process, with dorsal tooth, spine, or process, posterior margin without teeth or serrations. Segment X sclerotized laterally and dorsally, not particularly long or broad. Subgenital plates triangular, longer than width, outer margin convex, apex pointed or apex rounded or medial margin notched or excavated subapically, with two lateral rows of macrosetae, or with some irregularly arranged macrosetae near lateral margin, without or with few long fine setae.
