title: [Comparative morphology of eggs and nymphs of Triatoma vandae Carcavallo, Jurberg, Rocha, Galvão, Noireau & Lent, 2002 and Triatoma williami Galvão, Souza & Lima, 1965].
abstract: Eggs and all nymphs of these species were studied employing light microscopy (LM) and scanning electron microscopy (SEM). The major differences observed by LM in the eggs were related to the presence and the distribution of pores on the surface of their chorion. Morphological differences among three nymphal stages (1st, 3rd, and 5th) development of each species were observed. The differential characteristics are chromatic and in the shape of connexival spots. The ultrastructure of the ventral region of the head and the IX, X, and XI abdominal segments (anal tube) of the both species were described demonstrating morphological differences that can be used for diagnosis of the species.
