“…Curiously, a similar condition is observed in the genus Ladoffa, which is otherwise externally quite distinct from Parasubrasaca. The crown in Ladoffa has a median full-length longitudinal fovea, the epistomal suture is usually incomplete, the apical margin of the fore wings is slightly concave, and paraphyses are usually present (YOUNG 1977, LOZADA 1993, CAVICHIOLI & CHIAMOLERA 2001, LOZADA & FREYTAG 2010. These four features, especially the crown fovea and the concave fore wing apex, will readily distinguish Ladoffa from Parasubrasaca.…”
