Synonyms and other taxonomic changes
Two new species are described by Swift & Ray (2008):
Tragidion agave, sp. nov., and
Tragidion deceptum, sp. nov;
four new synonymies are proposed:
T. peninsulare Schaeffer and T. p. californicum Linsley = T. annulatum LeConte,
T. cyanovestis Chemsak and Linsley = T. bicolor Bates, and
T. armatum brevipenne Linsley = T. armatum LeConte;
T. densiventre Casey is revalidated from synonymy.
Numbers
8 spp. n. of Mex. (Swift & Ray 2008)
Size
Tragidion coquus - 19mm (1)
Identification
Most species within the genus Tragidion are difficult to identify, and species boundaries remain indistinct. Among species, adults are morphologically similar. (Swift & Ray 2008)
Range
The genus Tragidion Audinet-Serville is distributed throughout much of North America, Guatemala, and Honduras. (Swift & Ray 2008)
Remarks
Adults of one or both sexes are usually bright orange in color and mimic members of the pompilid genera Pepsis Fabricius and Hemipepsis Dahlbom (Hymenoptera: Pompilidae). (Swift & Ray 2008)
See Also
Tragidion is morphologically similar to other genera in the Trachyderini, such as Scythroleus Bates, Purpuricenus Dejean, Metaleptus Bates, Phoenicus Lacordaire, and Polyschisis Audinet-Serville. (Swift & Ray 2008)
