Remarks
- Systematics: Acanthococcus gracielae resembles Acanthococcus granarae, A. piptadeniae, A. dubius and A. arctostaphyli Ferris, 1955, the latter of the Nearctic region, by having six setae on prothoracic tibiae and five in the warm meso and metatorácicas. [Acanthococcus granarae differs from A. gracielae in the following points (A. gracielae brackets): (i) dorsal setae with sharp end (with end just rounded), (ii) pores abundant trilocular quinqueloculares and abdomen (rare), (iii) anal lobes with four ventral setae (two) and frontal lobes present (absent). A. dubius differs from A. gracielae (A. gracielae brackets) by: (i) setae arranged in longitudinal bands (with just rounded end, arranged in lines parallel to the cleavage), (ii) three setae ventral anal lobes (two) and (iii) abundant quinquelocular pores on the abdomen (rare). Acanthococcus arctostaphyli differs from A. gracielae (A. gracielae brackets) by: (i) marginal setae differentiated from the dorsal (undifferentiated), (ii) large dorsal setae arranged in three longitudinal lines (large setae on the margin of the body and head region) (iii) four setae ventral anal lobes (two) and (iv) numerous quinquelocular pores on abdominal segments (low). Acanthococcus piptadeniae differs from A. gracielae the following points (A. gracielae brackets): (i) three setae ventral anal lobes (two), (ii) metacoxas with 6-10 pores (about 50 pores) and (iii) present midplane (absent). (González & Clap, 2011)
- Structure: Abundant cone-shaped setae that are transverse lines in the thoracic and abdominal segments; macroconductos microconductos symmetrical "type B" numerous on both surfaces; setae undifferentiated marginal ridges; metacoxas with about 50 pores, 30 dorsal and 20 ventral anal lobes two ventral setae. (González & Clap, 2011)
- Economic Importance: Severe attacks have been noted on urban trees of Chloroleucon tenuiflorum, an unusual phenomenon among eriococcids in Argentina. Such attacks can damage hosts. (González, et al., 2017)
