Remarks

• Systematics: Parastictococcus brachystegiae is at first glance similar to P. gowdeyi but differs in the following ways: P. brachystegiae is about twice as large as P. gowdeyi, the narrow vertical bands of white secretion are not confined to the anterior stigmatic clefts as in P. gowdeyi. Several bands are present but are obscure in all but the early adult female. There are usually 6 segments to the antennae whereas P. gowdeyi has 5. The marginal fringe in P. gowdeyi is more regular and uniform since there is not the same variation in length of the setae as is found in P. brachystegiae. P. brachystegiae has many more hairs around the anal orifice and the setae on the ventral dermis are somewhat different (Hall, 1935a).
• Structure: Adult female hemispherical with a deep median transverse depression just in front of the anal orifice. Integument smooth and very highly polished, brown to reddish brown to black. Margin with narrow fringe of closely set pale orange-yellow spines. Ventral surface with a thin film of white secretionary matter which extends beyond the margin under the fringe. A series of short vertical bands of similar white secretion around the margin, associated with short vertical bands of spines, can be seen in some specimens; they are frequently missing or obscure in old individuals. Male with head broader than long with a few bristles in the frontal region. No median longitudinal suture obvious, but an ocellus close to each eye (Hall, 1935a).
• General Remarks: Best description and illustration of both sexes of adults, first and second stage females, male larva, prepupa and pupa by Hall (1935a). Hodgson (2002) used this species in a phylogenetic analysis of non-margarodid Coccoidea.
