Adults were obtained from field-collected larvae from fruits of two leguminous plant species, Bauhinia holophylla Steud (Caesalpinioideae) and Stryphnodendron adstringens (Mart.) Coville (Mimosoideae). These observations represent the first documented association between Holcocerini and Leguminosae. A photograph of the holotype and illustrations of wing venation and male and female genitalia are provided. Key Words: Brazil, cerrado, legumes, Neotropics, savanna, taxonomy Except for Amazonia, the cerrado is woodland savanna region in South Brazil’s largest biome. This vast savanna America and sustains some of the richest once extended over 2 million km2, about savanna flora in the world. one fourth of the country’s land area Nearly 6,500 plant species have been (Oliveira-Filho & Ratter 1995), but is recorded from the cerrado (Mendoc¸a et now reduced to 356,630 km2, or about al. 1998), including about 44% of all the 20% of its estimated original size (Da endemic vascular plants known from Fonseca et al. 2000).
