Dolichomitus jatai Loffredo & Penteado-Dias 2012

Brazil. Dolichomitus jatai sp. n. seems to belong to the zonatus species group, which are vespid mimics and are predominantly yellowish with brown or black marks; the wings are yellowish, and the males have shorter bodies. This species is similar to Dolichomitus annulicornis (Fig. 3), differing in the color of the flagellomeres: whereas the proximal five flagellomeres are black and the 6th and 7th yellow in Dolichomitus jatai sp. n., the proximal three or four flagellomeres are black and the next four or five whitish yellow in Dolichomitus annulicornis. The propodeum is dorsally smooth in Dolichomitus jatai sp. n., whereas in Dolichomitus annulicornis, there is a smooth and polished area that widens posteriorly. The males of the two species differ in the form of the mid-coxa: in Dolichomitus annulicornis, there are prominences separated by deep concavities (Fig. 14), and in Dolichomitus jatai sp. n., the surface of the mid-coxa is evenly convex (Fig. 13). In Dolichomitus zonatus, the propodeum is similar to that of Dolichomitus annulicornis, but it is narrower posteriorly. Dolichomitus cantillanoi has a narrower median longitudinal groove and distinct lateromedial secondary furrows, which are never present in Dolichomitus zonatus, Dolichomitus annulicornis or Dolichomitus jatai sp. n. Dolichomitus bivittatus, Townes, 1975, and Dolichomitus hypermeces, Townes, 1975, are different in color and have longer ovipositors, 12.0× and 21.0× as long as the hind tibia, respectively.
