Abstract:
A new species of Heterodermia from Costa Rica and Venezuela, in honour of the
Spanish Ambassador in Costa Rica, Juan José Urtasun Erro. The new species Heterodermia
urtasuni Chaves, Umaña & Sipman is described from Costa Rica and Venezuela, as one of
the many lichenological novelties discovered during the TICOLICHEN biodiversity
inventory in Costa Rica. The new species, which has also been found in Venezuela, is similar
to Heterodermia speciosa but differs in its large soralia produced on short, lateral lobes,
closely resembling the soralia of Heterodermia galactophylla. This new species is dedicated
to the Ambassador of Spain in Costa Rica, Mr. Juan Jose Urtasun Erro, in recognition of his
efforts to promote the study of biodiversity and bioalfabetización, which constitute solid
links that unite our people.
