Remarks: Morris (1870: 227) validated the name triatomella . However, he referred to Doubleday (1859: 35) for the identity of the species. Doubleday, in turn, gave triatomea as a ‘synonym’ of triatomella . However, Haworth (1828: 535) is the first author of the name triatomea . Therefore triatomella Morris, 1870 is a secondary junior synonym of Porrectaria triatomea Haworth, 1828 .
