Remarks

• Systematics: Slide-mounted adult female with undifferentiated marginal enlarged setae, dorsum with numerous slender, long, delicate enlarged setae (Morrison & Morrison, 1922). Because of the similarity of the species epithets "hirtus" and "hirsutus" these species have sometimes been confused. Due to its dense covering of setae on both the dorsum and venter, the adult female of L. hirtus would be difficult to confuse with that of any other known species of Lobimargo. It is also distinctive because of: (i) the stout, spinose setaealong the inner edge of each femur and tibia; (ii) the lack of sagittate setae on the dorsum (these are present in all otherspecies of Lobimargo); (iii) the lack of a strongly distinct marginal fringe; and (iv) the absence in most specimens of elongate caudal setae. Lobimargo hirtus is known solely on eucalypt hosts in the subgenus Eucalyptus. The remaining species of Lobimargo feed exclusively on eucalypts belonging to the subgenus Symphyomyrtus, with the exception of a single collection of what Beardsley thought was a secondinstar female of L. latrobeus from E. radiata.
• Structure: Adult female dark purple, but covered with a quantity of very short white filaments so that the general appearance is grey, form subglobular. First-instar nymph reddish or yellowish brown, active, elongate. Male pupa is covered by a white cylindrical sac of white cotton (Maskell, 1896b).
• Biology: There is much variation in the body and appendage size of adult females of L. hirtus, even within a collection site, and there is some variation in setal characteristics, depending on locality.
• General Remarks: Original description and illustration by Maskell (1896b). Redescription and illustration in Hardy, et al., 2011.
