Updated diagnosis.

A subgenus of the genus Megaphyllum differing from other subgenera and certain isolated congeners by the following combination of characters: promeres positioned considerably laterally (ca. 45° in most species) rather than completely anteriorly in relation to opisthomeres; promere considerably broader than opisthomere, with a deep median groove tightly enveloping the opisthomere anterolaterally; opisthomere with a small or vestigial anterior process, solenomere composed of two processes, an anterior and a posterior one, the former positioned at the end of the flagellum channel; vulva with an apically or subapically positioned opening, operculum shorter than, or rarely subequal to, bursa; hypoproct trapezoidal or broadly rounded.
