Balladyna contains ~6 nominal species, of which 2, B. fusiformis Kahl, 1932 and B. similis Kahl, 1932, were shifted to Balladynella Stiller, 1974. In 1972, I had shifted the latter to Holosticha. All these species have been studied little beyond their original description; their morphogenetic patterns are unknown. (ref. ID; 3925)
