The group of Trichromia leucoplaga ( Hampson, 1905)

This group is problematic as, in BOLD, for specimens externally identical we have three clusters: one in Central America and two in French Guiana. There are also specimens from South-East Brazil but they were not sequenced. T. leucoplaga was described from Saint Laurent du Maroni in French Guiana but we have two sequences in French Guiana at a minimum distance of 7.1 % (see simplified tree Fig. 18 below) and as the type was neither dissected nor sequenced we don't know which of the two species present in French Guiana is the true T. leucoplaga .

Nevertheless the species from Central America which is respectively at 2.8 % and 6.7 % from the two species from French Guiana is surely new and will be described below under the name Trichromia croceicervix sp. n.
