Remarks
- Systematics: Hodgsonicoccus differs from other Coccoidea by the combination of the following characters: body exceptionally large (ca. 2 mm), head with two ocular sclerites, each bearing less than 20 large and protruding simple eyes (vs. compound eyes, rows of simple eyes or two pairs of eyes in all other Coccoidea); antenna long, with binodose flagellar segments, each with long setae organized in whorls (similar to Monophlebidae), each becoming shorter distally; forewings elongate and narrowed apically, subcostal ridge extending to tip of wing, cubital ridge present, membrane with microtrichia (vs. absent in other archaeococcoids with compound eyes); hamulohaltere large and broad, with microtrichia (vs. absent in all Coccoidea), three hamuli inserted on anterior margin (vs. at the tip of hamolohaltere for all other Coccoidea); abdomen with several long, spinose setae on posterior segments; penial sheath triangular, with a large, everted endophallus. (Vea & Grimaldi, 2015)
Probably the most similar taxon to Hodgsonicoccidae is extinct Jersicoccidae, represented by Jersicoccus, described from New Jersey amber (Koteja, 2000b). Jersicoccus has a similar elongated forewing shape and binodose antennal segments, but the eyes are definitely compound, with numerous ommatidia, and waxy filaments are present on the abdomen, suggesting the presence of tubular ducts, absent in Hodgsonicoccus. Furthermore, phylogenetic results retrieved Hodgsonicoccus as sister group to other taxa without compound eyes, whereas Jersicoccidae was retrieved as sister family to all Coccoidea.
