Synonym

Acrobeles mariannae Andrassy, 1968

Note: Andrassy (1985) separated Seleborca from Acrobeles  mainly by the presence of a double cuticle and a lateral field with four incisures, two simple outer and two crenate or wavy inner lines. However, Shahina andf De Ley (1997) considered that the double cuticle feature had arisen independently in several genera and that the character was insufficient to establish a new genus.  They synonymized Seleborca with Acrobeles.  Species of Acrobeles are currently (2019) considered to be separated into two groups: the "Complexus group" with a double cuticle and the "Ciliatus group" with a single cuticle (Abolafia et al., 2019).
