Remarks
- Systematics: Neogreenia MacGillivray (Hemiptera, Coccoidea, Margarodidae) was established as a monotypic genus by MacGillivray (1921), with Monophlebus zeylanicus Green (1896) as type species. However, Green (1922) did not accept this new genus and placed M. zeylanicus in Kuwania Cockerell.Morrison (1928) discussed the type species of this genus, questioned its association with Kuwania, but did not assign it to a position in his Margarodidae system. Wu & Nan (2012) determined that Neogreenia could not be a member of the Margarodidae sensu stricto as presently understood as this family is now restricted to hypogaeic margarodoids, and so the best placement for Neogreenia is in the family Kuwaniidae.
Gavrilov-Zimin, 2018, resurrected the tribe Kuwaniini within the family Margarodidae to place the genus Neogreenia in relation to other genera that he felt belonged in a subfamily of Xylococcinae (Jansenus, Kuwania, Neogreenia, and Neosteingelia)
The genus Neogreenia now (2012) includes five species, which can be divided into two groups. Group I includes N. zeylanica and N. zizyphi, and Group 2 the other three species, N. osmanthus, N. sophorica and N. lonicera. The adult females of species in Group 1 are reddish in colour, without a group of discoidal pores on the posterior ventral abdomen and male stages have been collected. In Group 2, the body of the adult female is yellowish, there is a large group of simple pores on the posterior ventral abdomen and no male stages have yet been found.. (Wu & Nan, 2012)
The descriptions of the adult males of N. zeylanica (Green) and N. zizyphi were too simple to clarify their taxonomic relationships. After comparing the adult male of N. osmanthus with other adult males in Margarodidae sensu lato, it was found that N. osmanthus was close to Qinococcus podocarpus Wu 2022 (Qinococcidae). The adult females of N. osmanthus and Q. podocarpus both have longitudinal vulvas, but N. osmanthus differs mainly from the latter in having well-developed antennae and legs, and 8 pairs of abdominal spiracles, whereas Q. podocarpus has reduced antennae and legs, and 5 pairs of abdominal spiracles. The first-instar nymphs of these two species are also similar, with 7 segmented antennae and with the two apical antennal segments with similar features. Based on this discussion, Zheng & Wu (2023) determined that the genera Neogreenia and Qinococcus were closely related, and that Neogreenia should be transferred from the family Kuwaniidae to the family Qinococcidae.
- Structure: The adult females of species in Group 1 are reddish in color, without a group of discoidal pores on the posterior ventral abdomen and male stages have been collected. In Group 2, the body of the adult female is yellowish, there is a large group of simple pores on the posterior ventral abdomen. (Wu & Nan, 2012) Living adult male bocy elongate, 1.5-2.3 mm long. wing-span about 4.0 mm; with a dorsal tuft of long waxy filaments on posterior part of body; membranous parts of body yellowish to reddish, sclerotized parts brown, compound eyes black. Slide mounted male antennae 10 segmented and slender, flagellar segments each with many long, hair-like setae. (Zheng, et al., 2024)
- Biology: Neogreenia species live under the bark of woody hosts. They reproduce sexually or parthenogenetically. Neogreenia osmanthus, N. zizyphi and N. zeylanica are known to be bisexual; after emergence, adult females crawl on the bark to find a site for copulation and oviposition (Zheng & Wu 2023b; Tang & Hao 1995; and Green 1922). Zheng & Wu (2023b) reported that males of N. osmanthus represented a very low percentage (ca. 0.8%) of the population. In contrast, N. sophorica is parthenogenetic; the females do not move but remain under the bark at maturity.. Adult females of all species lay their eggs under the bark. (Zheng, et al. 2024)
