The taxonomic status and distribution of Thyanta custator (Fabricius) and Thyanta pallido-virens (Stal) (Heteroptera, Pentatomidae). American Museum novitates ; no. 1824

Abstract

"About 8000 specimens of both Thyanta custator (Fabricius) and Thyanta pallido-virens (Stnal) were studied. 2. Thyanta custator and Thyanta pallido-virens are not subspecific but two distinct species difficult to differentiate from each other. 3. Thyanta custator is restricted in its distribution to a territory extending roughly along the maritime portions of the Gulf states and the Atlantic seaboard northward to at least Long Island, New York, and in itself is not very variable. 4. Thyanta pallido-virens is a very plastic species and has, in addition to the basic species T. pallido-virens pallido-virens (Stal), at least three subspecific (geographical) populations: T. pallido-virens setosa, new subspecies; T. pallido-virens spinosa, new subspecies; and T. pallido-virens accerra (McAtee). 5. The phase previously described by McAtee as Thyanta custator var. accerra is apparently an autumnal-vernal (overwintering) dimorphic seasonal generation occurring in the species pallido-virens, custator, and calceata. 6. If the contents set forth in the foregoing article are accepted, a great part of the literature and bibliography dealing with these species must be revised"--P. 22.
