Synonyms and other taxonomic changes
Acanaloniidae and Caliscelidae are sometimes lumped with this family; several sw. genera (mostly restricted to CA) have been treated among Nogodinidae(1) "...because the wings are lacy, but the wax tails [of the nymphs] that can be spread when alarmed are characteristic of Issidae." (Dr Hamilton); Nogodinidae is not represented in our area (Dr Hamilton, pers. comm. to =v= 28.x.2010)
Explanation of Names
Issidae Spinola 1839
Numbers
ca. 90 spp. in 20 genera in our area(2), ~930 spp. in ~180 genera worldwide(3)
Identification
wings usually shorter than in Flatidae, and without the warty surface where the forewings meet over the back.
in nymphs, the wax filaments projecting from the rear are straight and bundled, not bushy. (Note: Tropiduchid nymphs may also have straight wax filaments.)
