Figure 12: Eggs general vision of Rhodniusmarabaensis sp. n. (A), Rhodniusprolixus (B), Rhodniusrobustus (C). cl: colar; cr: chorial rim; ex: exochorium; nk: neck; op: operculum.

Mentions: The most notable morphological features that distinguish Rhodniusmarabaensis sp. n. are the keel-shaped apex of the head, this feature is not accentuated in Rhodniusprolixus or Rhodniusrobustus ; the second antennal segment of Rhodniusmarabaensis sp. n. is 10.3 times larger than the first; in Rhodniusprolixus, it is 6.2 times larger, and in Rhodniusrobustus it is 8.3 times larger. The prosternum has a longer and more clearly shaped stridulatory sulcus relative to those of Rhodniusprolixus and Rhodniusrobustus. In Rhodniusmarabaensis sp. n. the transverse carinae that border the mesosternum and the metasternum are elevated and prominent, and possess convex curvature in the central portion. In Rhodniusprolixus, they are less elevated and prominent, and in Rhodniusrobustus they are interrupted in the central portion. The set of dark brown spots presents in the ventral abdomen of Rhodniusmarabaensis sp. n. does not appear in Rhodniusprolixus or Rhodniusrobustus. The ventral connective is also distinct among the three species: the black spots are smaller and, on the sixth segment, much smaller in Rhodniusmarabaensis sp. n. The apex of the endosoma of male genitalia of Rhodniusmarabaensis sp. n. was found to be long and straight, in Rhodniusprolixus, the apex is long and convex, and in Rhodniusrobustus it is shorter, wide, and convex. The posterior surface and the ventral surface of the ninth and tenth segments of external female genitalia are distinct in the three species. Rhodniusmarabaensis sp. n. eggs possess chorion rims, whereas those of Rhodniusprolixus and Rhodniusrobustus do not (Figs 1, 3, 5, 6, 7, 10, 11, 12, 13).
