Genus Titanogrypa

The monophyly of this group was supported by three uniquely derived apomorphies: (1) posteroventral margin of tergite V round, (2) cercal apex rounded in lateral view, and (3) basiphallus with a dorsal hump. Giroux et al. (2010) found the character state of the scutellum with lateral white setae as one of the uniquely derived apomorphies supporting Titanogrypa . However, we found that this character state was not present in all Titanogrypa species examined here, but it is still considered here as a groundplan trait.

Lopes (1 969, 1 98 3) co ns i d er e d Tita nog ry pa as paraphyletic. Accordingly, he included Titanogrypa luculenta as part of Cuculomyiini and Titanogrypa alata as part of Sarcophagini . Giroux et al. (2010) found the genus Titanogrypa to be monophyletic, which later was contradicted by the molecular-based analysis of Stamper et al. (2012). With a larger sample of species of this genus, we found Titanogrypa to be monophyletic in all our morphology-based analyses.
