Sensu lato strictly speaking, I believe, means "any member of any
subgenus of the genus in question". Say, Volema sl could refer to
species in Volema ss, Hemifusus, Melongena, Pugilina or Cyrtulus.
Volema sensu stricto (ss) would refer to any member of only the
nominate subgenus, Volema (Volema).

You're out of luck on this one... unless, as suggested, you use "sensu Abbott".
