( Fig. 1 ) Type material . Holotype male, Brazil , Mato Grosso do Sul, Corumbá, BEP - Mata ciliar, Rio Miranda, 02.xi- 02.xii.2011 , C. J. E. Lamas & S. S. Nihei (SISBIOTA-Project). Paratypes : 3 males same data as holotype . 2 males same data as holotype except for 03-18.x.2011 . Diagnostic characters . Denopelopia moema can be distinguished from most other Denopelopia species by the abdominal segment I pale, with two lateral small brown spots on anterior margin, A II–III pale, A IV pale with one medial brown spot on anterior margin, A V–VIII with posterior dark brown bands, covering almost whole segments. Adult males of D. moema appear most similar to those of D. atria Roback & Rutter in the AR and abdominal coloration. However, the distinctive brown spots on anterior margin of abdominal segment I and IV separate D. moema from the former species. Etymology . Refers to the main character in the epic poem "Caramuru" from Santa Rita Durão, an Indian woman of the Tupi group named Moema , which means sweet. Description. Adult male. (n = 6) FIGURE 1A–F.
