Remarks

• Systematics: Several features make this new fossil family quite remarkable: (1) the eye structure was interpreted as two ocular sclerites because they completely surround the head, as opposed to laterally located compound eyes. These sclerites, however, bear multiple rows of large simple eye facets. This type of eye structure could possibly indicate an intermediate state between compound eyes with multiple ommatidia and one with reduction of the eyelets to two pairs, as in neococcoid families. (2) The binodose antennal segments with whorls of setae, however, are similar to archaeococcoids, such as are found in some Recent Monophlebidae genera (e.g., Drosicha) as well as in extinct Jersicoccidae. (3) Both forewing and hamulohaltere are also peculiar: the generally elongated shape of the forewing is similar to Jersicoccidae and venation (subcostal ridge extending to tip of wing) is similar to, for instance, Recent Putoidae and extinct Labiococcidae. (4) Bifurcated setae are present in some Margarodidae, Stigmacoccidae, and Kuwaniidae, and all Monophlebidae and Coelostomidiidae (Hodgson and Foldi, 2006), although none of these recent families present the same combinations of characters as found in Hodgsonicoccidae. (5) Finally, the last abdominal segments present long and extremely sclerotized setae projecting posteriorly, unique to this family. Overall, the combination of the striking features listed above is unknown among Coccoidea and therefore justifies the creation of a new family, genus and species. (Vea & Grimaldi, 2015)
