Interpretive Summary: Scale insects are frequently encountered on various agricultural commodities at U.S. ports-of-entry. These pests may be a serious threat to US agriculture if they are introduced and become established and have the potential for causing billions of dollars of damage each year. To counteract this threat, it is important to know the correct identity of species that have been collected in quarantine. The results of this research includes a detailed analysis of a genus of ensign scales including 4 previously described species and 9 species unknown to science. This information is important to US quarantine programs so that inspectors and identifiers will be able to determine the correct identify of the species and will be able to make informed decisions on actions to be taken against these pests.
Technical Abstract: Nine new species of Newsteadia ortheziids are described and detailed redescriptions are provided for the four species previously known from the Afrotropical Region including N. gomyi Strickland, N. mauritiana Mamet, N. montana Mamet, and N. wacri Richard. A key is presented for the 13 species known to occur in the area and a detailed discussion is presented on the homology of the wax plates that cover the body of these fascinating scale insects.
