Remarks

• Systematics: C. conchioides is the only species known in this genus and can be separated from species in the other genera in the Cardiococcinae by the combination of the following characters: (i) the presence of preopercular pores distributed in a longitudinal median single line anterior to anal plates to the head, (ii) the undifferentiated stigmatic setae and stigmatic spines, and (iii) the presence of a few pregenital 5-loculi disc-pores, restricted to either side of the anal cleft. The first-instar nymphs of C. conchioides are very similar to species in 3 other genera within the Cardiococcinae, namely Ceroplastodes dugesii (Pellizzari et al., 2008), Pseudokermes nitens (Cockerell) and Inglisia patella Maskell (Hodges & Williams, 2003). No dorsal microducts or trilocular pores could be detected on the nymphs of C. conchioides (present on the nymphs C. dugesii) and the protarsal digitules were similar to those on the other legs (currently unknown on other 1st-instar Coccidae nymphs). (Vea, 2011)
• Structure: Information given by Goux (1933): adult female "covered by a waxy, glassy test, easily removable from the body, and composed of two symmetrical valves, lamellibranch-like with a hooked edge, each of the two hooks being directed backwards. The line joining the valves forms a deep furrow, which becomes narrower next to the hooks, becoming wider anteriorly and particularly posteriorly. Each valve has small ridges radiating from the top. In general, the test just resembles a small lamellibranch shell. When separated from the rest of the body, it is almost transparent; when in place, it is yellowish-grey and slightly iridescent. Length 3.0 mm, width 2.0 mm and height 2.5 mm. The dorsal surface bears two prominences separated by a longitudinal and median groove that corresponds to the valve sutures. The ventral surface is flat and even concave." Slide mounted adult female body broadly oval, pear-shaped with a broader posterior region; anal cleft short with divergent sides, forming an obtuse angle. Dorsum wider than venter. Pregenital disc-pores present, each with five loculi on either side of anal cleft. Absence of dorsal setae.(Vea, 2011)
• Biology: According to Goux (1933), the adult females become mature in August and most of them were sheltering completely developed nymphs, suggesting that they are ovoviviparous. (Vea, 2011)
• General Remarks: Description of the adult female and first-instar nymph given by Borchsenius (1957). Detailed redescription and illustration of adult female, young teneral female, and first-instar mymph in Vea, 2011.
