Castolus plagiaticollis Stål, 1858  

( Fig. 9D View FIGURE 9 , 10C View FIGURE 10 )

Remarks. Castolus plagiaticollis   is a conspicuous species with red head, red femora, dark tibiae, a large ovoid marking on the posterior lobe of the pronotum, mostly yellowish corium and clavus with the apex of the corium black, and a black membrane except its apex which is translucent ( Maldonado 1976). Nonetheless, it is variable regarding its hemelytral color pattern. Champion (1899) had already mentioned that some specimens from Mexico and Guatemala had a more darkened clavus and corium.Among the specimens examined and the observations from iNaturalist (https://www.inaturalist.org/observations?place_id=any&q=castolus%20plagiaticollis), several instead of a yellow corium have a whitish one; a few ones have a more extended dark area on the apex of the corium, reaching in some specimens almost half the corial length, or on the other hand have a completely yellow corium without dark areas. Very rarely, the specimens have a mostly black corium being yellow only the costal area and the base of clavus. Because color patterns are important to delimit species in Castolus ( Maldonado 1976)   , the observed color variation in C. plagiaticollis   highlights the importance of understanding the intraspecific color variation to adequately assess the specific limits for other species in Castolus   .

Quiroz & Carmona (2011) listed two specimens identified as C. plagiaticollis   from MEFLG. We examined two additional specimens from MEFLG and corroborated their initial identification. The examined Colombian specimens all have a yellow corium and small apical dark area on the corium.

Distribution. Originally described from Mexico ( Stål 1858), with subsequent records from Honduras ( Maldonado 1990), Guatemala, and Panama ( Champion 1899). It represents the first formal record of the species from South America, and a new country record from Colombia, extending the known distribution into South America ( Fig. 10C View FIGURE 10 ).
