Robison & Pantoja-Alor (1968) erected the Subfamily Plicatolininae to include three genera: Plicatolina Shaw, 1951 ; Plicatolinella Robison & Pantoja-Alor, 1968 ; and a third undescribed and unnamed genus from the western United States . Robison & Pantoja-Alor (1968) emphasized low cranidial convexity, a quadrate glabella bearing 4 pairs of lateral glabellar furrows, and short anterior border and preglabellar field as defining characteristics for the new subfamily. The pygidial margin was either entire ( Plicatolina ) or bilobed ( Plicatolinella and the unnamed genus). Mendoparabolina Rusconi, 1951a exhibits these characters and is included in the subfamily. Taylor (1976) transferred the genus Westergaardites Troedsson, 1937 into the subfamily. Benedetto (1977) erected Paraplicatolina , with P. acantha as the designated type species, and included it in the Plicatolininae . Paraplicatolina acantha , however, has a subtrapezoidal glabella and apparently lacks S4 lateral glabellar furrows: the assignment bears further consideration.
