description: Trichogramma marandobai Brun, Moraes & Soares, 1986   
 Trichogramma demoraesi: Zucchi et al. 1991 (checklist); Zucchi & Monteiro 1994: 52 (record); Zucchi & Monteiro 1997: 53 (catalog); Querino & Zucchi 2005: 51 (key); Ronchi-Teles & Querino 2005: 515 (record); Zucchi et al. 2010: 222 (catalog); Querino & Zucchi 2011: 38 (identification guide).   
 Diagnosis. Genital capsule long; dorsal lamina tapering from apex to base, not extending beyond apex of volsellae; dorsal lamina with narrow posterior extension and rounded apex at same level as intervolsellar process; intervolsellar process long and stout; ventral carina not extending beyond midlength of genital capsule (Fig. 2 C, D). Antennae with flagelliform setae relatively short, tapering at apex (Fig. 4 B).   
 Type material. Holotype and paratype were deposited in the ICB/UFMG collection. However, these types are no longer at UFMG (Prof. Pedro M. Linardi, pers. comm.).   
 Examined material. BRAZIL, Minas Gerais: Janaúba, 9.iii.2010 15 ♂ (J.M. Vieira) (ESALQ). Espírito Santo: Itapemirim, 1.vii.1985, 1 ♂, ex Erinnyis ello eggs (identified as T. demoraesi) (ESALQ). Minas Gerais: Lavras, 15.i.2001, 1 ♂, 20.xii.2000, 1 ♂, ex Erinnyis ello eggs (identified as T. demoraesi) (ESALQ). Paraná: Londrina, 18.iii.1986, 1 ♂, ex Erinnyis ello eggs (identified as T. demoraesi) (ESALQ). São Paulo: Atibaia (Experimental Station of the Biological Institute), 5 ♂; Piracicaba, 1.vii.1999, 15 ♂, ex Erinnyis ello eggs (identified as T. demoraesi) (ESALQ). PERU, locality unknown, 1.v.1999, 15 ♂, ex Erinnyis ello eggs (identified as T. demoraesi). Loreto: Estación Jenaro Herrera, 13.i.2011, 10 ♂, ex Erinnyis ello eggs (ESALQ).   
 Distribution. Brazil: Amazonas, Minas Gerais, Espírito Santo, Paraná, and São Paulo; Peru: Loreto.   
 Associated plant. Manihot esculenta Crantz.   
 Habitat. Farm.   
 Host insect. Erinnyis ello (L., 1758).   
 Comments. The comparative morphological analysis of the paratype and the specimens previously identified as T. demoraesi from eggs of E. ello in cassava, revealed that these specimens belong to T. marandobai (Table 1). Trichogramma demoraesi differs from T. marandobai by having longer flagelliform setae, narrower dorsal lamina at the base of the posterior extension (fork-shaped), a deeper dorsal opening, and a long stout intervolsellar process with the apex truncated or pointed (Table 1). Therefore, T. demoraesi is associated only with G. bipennaria in forest habitats in Brazil. Trichogramma marandobai has previously been recorded as a parasitoid of E. ello eggs.
