Forero, Dimitri & Mejía-Soto, Andrés, 2021, A striking sexually dimorphic new species of Castolus (Hemiptera: Heteroptera Reduviidae) from Colombia, with new records from Neotropical countries and taxonomic notes on the genus, Zootaxa 5048 (4), pp. 538-560 : 556

Castolus rufomarginatus Champion, 1899

( Figs. 9E , 10C )

Remarks. We only found two specimens in the collections examined. This species is easily recognized due to its dark overall coloration with a bright red band on the posterior and lateral margins of the posterior pronotal lobe. Males have more protruding eyes than females.

Distribution. This species was described from Mexico and Guatemala ( Champion 1899), with additional records from Venezuela ( Maldonado 1976). It represents new country records from Costa Rica, Colombia, and Ecuador, although only iNaturalist observations were available from Costa Rica and Ecuador ( Fig. 10C ).
