Systematics: Acanthococcus riojensis resembles A. microspinus Kozár & Konczné Benedicty in the types of setae, the presence of frontal lobes and the presence of small medial setae on the posterior abdominal segments (Kozár & Konczné Benedicty 2008). However, the two species differ in that A. microspinus exhibits (character-states for A. riojensis in brackets); (i) larger dorsal setae, each 36–67 μm long (19–53 μm long); (ii) larger dorsal setae not forming longitudinal lines (forming longitudinal lines); (iii) only one type of microtubular duct (two types), and (iv) a 2-segmented labium (3 segmented). (González, et al., 2017)
Structure: Adult female: Dorsal setae conical and numerous; macrotubular ducts symmetrical; microtubular ducts of both types A and B present. Margin with single conical seta on each abdominal segment. Ventral surface with a line of small, conical setae in submargin; microtubular ducts of both types present, sparse; legs long and slender; metathoracic coxae with sparse pores. (González, et al., 2017)
General Remarks: Detailed description of adult female and second instar male, and illustration in González, et al., 2017.
