Remarks
- Systematics: The main diagnostic characters of this genus are the compact group of large-sized quinquelocular pores on the margin of the dorsum and on the posterior ventral abdominal segments. Hoyicoccus is probably most similar to Phacelocuccus Miller, as defined by Gullan & Strong (1997) and Hardy & Gullan (2007); another genus with groups of quinquelocular pores but, on Phacelocuccus, these pores are on the venter only, are smaller and more widespread. Hoyicoccus also differs from Phacelococcus in the possession of frontal tubercles, or lobes, and in having each macrotubular duct with a simple filamentous inner ductule. In addition, the anal lobes of Hoyicoccus hendersonae are well developed, whereas those on Phacelococcus species are small, rounded and barely discernible. Clusters of quinquelocular pores are also present on species of the family Dactylopiidae and in the second-instar males of Danumococcus panosoreae Takagi & Hodgson; as discussed by Takagi & Hodgson (2005). (Kozár, et al., 2009)
- Structure: Body of adult female elongate oval, cuticle membranous. Venter: antennae 6 segmented, frontal tubercles present. Labium with segments II and III fused; basal segment with a pair of short robust setae. Stylet loop much longer than body. Quinquelocular pores of two sizes; smaller pores, sparsely scattered over most of surface; larger pores present in marginal groups on each of last 4 abdominal segments. Legs well developed, each tibia about as long as tarsus, midcoxae and hindcoxae with apinulae on anterior surfaces, hindcoxae with large, irregularly-shaped translucent pores on posterior surfaces. Macrotubular ducts present, of 2 sizes; larger ducts each with inner ductule longer than main ductule and with a flower-shaped terminal gland; and smaller ducts each with short filamentous ductule. Cruciform pores absent. Spine-like setae present around submargin. Venter of each anal lobe with 1 subapical seta. Suranal setae hair-like. Dorsum: spine-like setae robust, present in rows on all segments, not differentiated from marginal setae. Anal lobes well developed, each with 3 robust spine-like setae plaus a long flagellate apical seta. Anal ring with 6 anal ring setae, each about twice length of ring; anal ring pores few in a single row. Cauda present. Quinquelocular pores of large type, similar to larger loculate pores on venter, present in 13 compact groups around margins, each on an area of sclerotised derm. Macrotubular ducts absent. Microtubular ducts present, few, elongate. Most of cuticle minutely nodulose. (Kozár, et al., 2009)
- Biology: Although the external appearance of Hoyicoccus in life is not yet know, it is likely that species in this genus secrete strong wax filaments around the margin. (Kozár, et al., 2009)
