Cervical gills absent but with single small membranous, gill-like nubs outside of lateral cervical sclerites.
Male
Paraprocts divided into 2 lobes; inner lobe short and narrow; outer lobe sclerotized ventrally and membranous dorsally, very large and triangular or elongate in shape. Cerci mostly sclerotized, lateral sclerotized strip usually terminates at apex in 1 to 3 spines or hooks. Dorsal sclerite of epiproct large and broad at base, mostly darkly sclerotized, extending dorsolaterally, narrower around lateral knobs and then very large, usually completely covering lateral aspects of epiproct and part of ventral aspect, anterior area usually lightly sclerotized; ventral sclerite darkly sclerotized, broad at base, with lateral knobs at basolateral corners, tapering toward apex, forming parallel ridges, one on each side of midline, usually covered by dorsal sclerite near tip of epiproct, extending inward and upward to dorsal surface, visible portion paired and quite variable in shape, often bearing spines or hooks.

Sternum 7 enlarged and extended posteriorly, covering part or all of sternum 8, produced area sclerotized. Sternum 8 narrow and mostly membranous, with small sclerotized area at genital opening. Cerci mostly sclerotized.
