Trichogramma demoraesi Nagaraja, 1983

Diagnosis. Genital capsule elongate and narrow; dorsal lamina narrow at base, fork-shaped; intervolsellar process narrow and distinct, apex slightly pointed; ventral processes positioned anterior to base of intervolsellar process ( Fig. 1A–C ). Antennae with flagelliform setae moderately long, gradually tapering at apex ( Fig. 1D ).

Type material. Trichogramma demoraesi . Paratype ♂, BRAZIL, Minas Gerais: Felixlândia, 11.v.1978 (Brun, Moraes, and Soares) ( NHM) (examined). The holotype and “ allotype ” were deposited at the Institute of Biological Sciences, Federal University of Minas Gerais (ICB/ UFMG), Brazil. Not found.

Distribution. Minas Gerais, Brazil.

Associated plant. Eucalyptus grandis Hill (ex Maiden) ( Myrtaceae ).

Habitat. Forest.

Host insect. Glena bipennaria (Guenée, [1858]) .

Comments. Specimens reared from eggs of E. ello , previously identified as T. demoraesi , differ from the paratype as follows: i) flagelliform setae of specimens are shorter than in the paratype (ratio of the length and width of setae is 1.52 and 2.05 respectively); ii) basiconic sensilla formula 1-2-2-0(1)-1-1 (specimens) and 1-1-2-0-1-1 (paratype), therefore, in the paratype there is only one sensillum in position 2 and none in position 4; iii) intervolsellar process broader in the specimens than in the paratype; iv) posterior extension of the dorsal lamina broader in the specimens than paratype, whose dorsal lamina is fork-shaped.
