Remarks

• Systematics: The second-instar female of Ac. hoyi is most similar to the second-instar female of Ac. kemptoni by having the lateral enlarged setae noticeably larger than the dorsal medial and mediolateral setae. They differ as follows (character states in brackets are of Ac. hoyi): large-sized lateral setae restricted to abdomen and head (present around entire body margin); each hind tibia without middle seta (with middle seta). (Miller & Stocks, 2022) Among the first-instar nymphs described in Miller & Stocks (2022), Ac. hoyi is most similar to the first-instar nymph of Ac. kemptoni in having the medial and mediolateral setae conspicuously shorter than the marginal setae. They differ as follows (character states in brackets are of Ac. hoyi): large-sized marginal setae restricted to abdomen and head (present around entire margin); each tibia without middle seta (with middle seta); with 1 large-sized setae on each lateral margin of each abdominal segment (with 2).
• Structure: Slide-mounted adult female with: enlarged setae cylindrical, apices truncate, marginal setae conspicuously larger than other setae on dorsum or with large setae along margin and in medial area, with 2 rarely 3 lateral setae on margin of each abdominal segment; microtubular ducts short, with 2 sclerotized areas (Miller & Miller, 1992).
• Biology: Assumed to infest grass blades and sheaths as an immature and to produce an ovisac on leaf blades as an adult (Miller & Miller, 1992).
• General Remarks: Detailed description and illustration given in Miller & Miller (1992). Incorrectly described and illustrated as Eriococcus kemptoni by Ferris (1955a).
