Remarks

• Systematics: Hodgson & Williams (2018) determined that this species belongs to neither Paralecanium nor Mesolecanium. In addition, in possessing three types of ventral tubular ducts, they determned that it was clear that it did not belong to either the Paralecaniini (despite having the eye-spot displaced onto the dorsum) nor to the genus Coccus which has only 1 type of ventral tubular duct. The position of the eyespot on M. marianus, along with the rather broad marginal setae, may be why Cockerell suggested it was a Paralecanium species. The presence of three types of ventral tubular ducts suggests a possible relationship with the Pulvinariini, but it does not fit into any of the current genera and has not been recorded as producing an ovisac. Therefore, they raised a new genus, Mariacoccus Hodgson & Williams for it, although its wider relationships are uncertain.
• Structure: Unmounted material. “Long-oval, a little over 4 mm long and 2 wide, shining red-brown, strongly pitted; back obtusely longitudinally keeled. Marginal area with some very thin easily deciduous wax” (Cockerell, 1902: 455 in Hodgson & Williams, 2018). Slide-mounted adult female. Body oval, probably quite convex in life. Anal cleft apparently not fused but with parallel margins, about 1/7th total body length. Length 3.5–4.0 mm, width 2.75 mm. (Hodgson & Williams, 2018)
• General Remarks: Description and illustration of adult female by Fonseca (1957) and by Granara de Willink et al. (2010). Detailed redescription and illustration in Hodgson & Williams, 2018.
