Remarks

• Systematics: Microtubular ducts abundant on both surfaces; metacoxae each with 40–50 (20–30 dorsal and 15–20 ventral) translucent pores; anal lobes each with 4 ventral setae; anal ring with 2 rows of pores; spiracles large in comparison to legs, each about same size as a coxa. (Goonzalez, et al., 2020) Acanthococcus lanatus differs from A. christopherus Foldi & Kozár, which was described also from Eugenia in Brazil, in having (character-states of A. christopherus in brackets taken from Foldi and Kozár, 2007): (i) dorsal setae arranged in transverse bands across all segments; larger setae present along body submargin, (dorsal setae arranged in 2 longitudinal medial bands and 9 transverse rows), ii) metathoracic coxae with 40–50 translucent pores and femur with 5-7 pores (coxae with 90–115 pores and femur with 10–15 pores), iii) quinquelocular pores throughout venter; numerous in segmental bands on abdominal segments, also present in a band of 40–50 pores extending from each anterior spiracle to margin and in a group around each posterior spiracle (not present in a band from each anterior spiracle to margin), iv) microtubular ducts abundant throughout on both surfaces (scattered throughout on dorsal surface, absent on ventral surface), and v) anal ring with 2 almost complete rows of pores (with one row). (Gonzalez, et al., 2020)
• Structure: The female is wholly enveloped by a layer of white waxy, floccose, sub–spherical in shape, 5–6 mm in diameter, without orifice in the apex, and usually fixed in the axils of the leaves and branches, sometimes isolated; most frequently the individuals are grouped in number of 2–8 or more First instars are elliptical (Hempel, 1932).
• General Remarks: Detailed description by Hempel (1932). Redescription in Gonzalez, et al., 2020.
