description: Monopelopia caraguata sp. n.
Type material: Holotype: male with pupal exuviae (MZUSP) Brazil, Santa Catarina State, Florianópolis (UCAD), in Vriesea vagans (Smith), 6.iv.2002, C.B. Marcondes & L.C. Pinho leg.. Paratypes: 1 male with larval and pupal exuviae, same data as holotype except for Nidularium innocentii Lemaire, 8.xi.2002; 1 male with pupal exuviae, same data as holotype except for Vriesea philippocoburgii Wawra, 11.iv.2002; 1 male with pupal exuviae, same data as holotype except for Hohenbergia augusta (Velloso), 15.iv.2002; 1 male with pupal exuviae, same data as holotype except for Nidularium innocentii, 09.v.2002; 1 female; with larval and pupal exuviae: same data as holotype except for Aechmea nudicaulis (Linne), 27.viii.2002. 1 female; with larval and pupal exuviae: same data as holotype except for Nidularium innocentii, 15.iv.2002.
Additional material ascribed to this species: 2 female with pupal exuviae (Nidularium innocentii, Vriesea gigantea); 2 pupal exuviae associated with larval exuviae (Nidularium innocentii, Vriesea gigantea).
Diagnostic characters: Male adult. The combination of T I­V with a broad oral brown band; T VI brown, T VII and VIII brown with an anal pale band; genitalia brown; 3 strong pale bristles on the second palpomere; TIX with 4­5 setae on each side. Pupa. The combination of genital sac longer than anal lobe; plastron plate elongated and reaching at least one third of the total length of the thoracic horn; pupal exuviae uniformly dark brownish, 4 lateral setae on segment VIII. Larva. The combination of AR 3.08, no dark claws on the posterior parapod and 5 teeth on the inner margin of the smallest claw of the posterior parapod, will distinguish this species among all other Monopelopia species.
