Castolus pallidus Maldonado, 1976

( Figs. 9B View FIGURE 9 , 10B View FIGURE 10 )

Remarks. Although no specimens from Colombia were examined, digital images from iNaturalist of two adult specimens were studied. Both specimens agree completely with the coloration pattern from specimens from Panama ( Fig. 9B View FIGURE 9 ). Castolus pallidus is extremely similar to C. bolivari Brailovsky, 1982 ( Fig. 6B View FIGURE 6 ), and the two apparently do not overlap in distribution. Both species have the postocular area of the head black, the basal area of the hemelytron black, a reddish scutellum, and the apex of the femora black. Castolus bolivari has a narrow black area dividing the anterior and posterior pronotal lobes, and a broad red area on the anterior half of the posterior lobe of the pronotum, whereas C. pallidus has a unicolor posterior lobe and no dark markings between the anterior or posterior lobes. In live specimens the posterior lobe of the pronotum in C. pallidus is pinkish. Because C. bolivari was described from a single female specimen ( Brailovsky 1982), study of the male genitalia of these two closely related species will help to better assess the species limits.

Distribution: This species was described from Panama with no further records from other countries ( Maldonado 1976). Examination of iNaturalist records show that this species is more widespread in Central America. This is a new species record from Costa Rica and Colombia ( Fig. 10B View FIGURE 10 ).
