“…Slide-mounted specimens were prepared using the method of Borchsenius (1950), stained in acid fuchsin and mounted in Canada balsam. Morphological terms generally follow those of Williams (1985) and Kozár et al (2009), except that the large simple pore on the dorsum and ventral margin is referred to as the macrodisc pore. Measurements are in micrometres (μm) except that the length and width of the body are in millimetres (mm).…”

The Chinese species Cryptococcus ulmi Tang & Hao is found to be distantly related to other sampled Cryptococcus species based on both molecular and morphological study. A new felt scale genus, Macroporicoccus Nan & Wu gen. n., is erected therefore for C. ulmi. The new genus differs from other eriococcid genera due to the presence of large simple pores, here referred to as macrodisc pores. The adult female of Macroporicoccus ulmi (Tang & Hao) comb. n. is redescribed and illustrated. Some important taxonomic characters are illustrated with SEM photographs.

“…The morphological terms follow those of Williams (1985b) and Miller & McKenzie (1967), and of Koteja (1980) for antennal sensilla. Illustrations were prepared by PJG by making a pencil outline sketch using a drawing tube attached to an Olympus compound microscope, then details were perfected by eye at higher magnifications and the final drawing was inked on tracing film placed over the pencil sketch.…”

A new scale insect, Aolacoccus angophorae gen. nov. and sp. nov. (Eriococcidae), is described from the bark of Angophora (Myrtaceae) growing in the Sydney area of New South Wales, Australia. These insects do not produce honeydew, are not ant-tended and probably feed on cortical parenchyma. The adult female is pupillarial as it is retained within the cuticle of the penultimate (second) instar. The crawlers (mobile first-instar nymphs) emerge via a flap or operculum at the posterior end of the abdomen of the second-instar exuviae. The adult and second-instar females, second-instar male and first-instar nymph, as well as salient features of the apterous adult male, are described and illustrated. The adult female of this new taxon has some morphological similarities to females of the non-pupillarial palm scale Phoenicococcus marlatti Cockerell (Phoenicococcidae), the pupillarial palm scales (Halimococcidae) and some pupillarial genera of armoured scales (Diaspididae), but is related to other Australian Myrtaceae-feeding eriococcids.

“…Froggatt (1921: 156) went so far as describing it as 'analogous with the more distinct tails of Apiomorpha and Ascelis'. In eriococcids (which include Cystococcus and Ascelis) the vulva is typically found on or between abdominal segments VII and VIII (Williams 1985;Gullan and Jones 1989). However, in Apiomorpha the vulva appears to have been displaced anteriorly by at least one segment (Gullan and Jones 1989).…”

Abstract. Australia houses some unusual biota (insects included), much of which is undescribed. Cystococcus Fuller (Hemiptera : Sternorrhyncha : Coccoidea : Eriococcidae) currently comprises two species, both of which induce galls exclusively on bloodwoods (Myrtaceae: Corymbia Hill & Johnson). These insects display sexual dichronism, whereby females give birth first to sons and then to daughters. Wingless first-instar females cling to their winged adult brothers and are carried out of the maternal gall when the males fly to find mates -a behaviour called intersexual phoresy. Here, we use data from two gene regions, as well as morphology and host-use of the insects, to assess the status of a previously undescribed species. We describe this newly recognised species as Cystococcus campanidorsalis, sp. nov. Semple, Cook & Hodgson, redescribe the two existing species -C. echiniformis Fuller and C. pomiformis (Froggatt), designate a lectotype for C. echiniformis, and provide the first descriptions of adult males, and nymphal males and females for the genus. We have also reinterpreted a key morphological character of the adult females. This paper provides a foundation for further work on the genus, which is widespread across northern Australia and could prove to be useful for studies on biogeography and bloodwood ecosystems. urn:lsid:zoobank
