Keys

• GonzalClJu2020: pp.7-8 ( Adult (F) ) [Acanthococcus species from Brazil]

Remarks

• Systematics: Microtubular ducts sparse, present only along margin on both surfaces; marginal setae differentiated from dorsal setae on abdominal segments; metacoxae with 6–10 dorsal pores; prothoracic tibia with 6 setae; anal lobes each with 3–4 ventral flagellate setae and a long, narrow inner anterior dorsal setae. (Gonzalez, et al., 2020) Acanthococcus campinensis differs from A. christopherus Foldi & Kozár (2007), from Brazil, in having (character-states of A. christopherus in brackets taken from Foldi and Kozár, 2007): (i) smallest dorsal setae arranged in transversal bands in all segments, largest dorsal setae distributed in longitudinal lines in submarginal, lateral and medial regions, the latter reaching as far as abdominal segment IV (dorsal setae arranged in 2 longitudinal medial bands and 9 transverse rows), ii) frontal lobes absent (present), iii) metathoracic coxae with 6–10 translucent pores and femur without pores (coxae with 90–115 pores and femur with 10–15 pores), iv) trilocular pores sparse, in medial thoracic region and near spiracles (not described, apparently not present), v) microtubular ducts restricted to margin on both surfaces (scattered throughout on dorsal surface, absent on ventral surface), vi) ventral macrotubular ducts with a broad cup, narrow, present (not described, apparently not present), and vii) submarginal and lateral cruciform pores present in cephalic and pro and mesothoracic regions (in a submarginal band from head to about abdominal segment III). (Gonzalez, et al., 2020)
• Structure: Sac of female felted. When adult female is boiled in KOH it turns transparent The female forms a thick, felted, non-sticky sac, with the rear end facing upwards and provided with a small circular hole. Some transverse striae are barely perceptible. The sac measures about 3 mm in length and 2.2 mm in width. (Hempel, 1937).
• General Remarks: Most detailed description of adult female and first instar by Hempel (1937). Redescription and illustration in Gonzalez, et al., 2020.
