Arboraptor Mendes, Oliveira, Chamorro-Rengifo & Rafael , gen. nov.

Figures 1–10 and 19

Type species. Arboraptor viridis sp. nov., here designated.

Diagnosis. Male. Mandibles asymmetrical, left mandible ensiform, about twice the length of right ( Fig. 2B ). Head in frontal view laterally broadened and rounded, being the distance between genae about 2.5 times longer than distance between eyes ( Fig. 2B ). Tegmina covering all the abdominal tergites, however the apex of tegmen does not extend beyond the apex of the cerci ( Fig. 2A ). Styli long, thin, dorso-ventrally flattened and parallel sided, apex blunt ( Fig. 2I –J ), in lateral view curved ( Fig. 2K ). Titillator process and titillator sclerite forming two c-

shaped opposing pieces, slightly overlapping at midline and surface covered by numerous rugose small triangular projections ( Fig. 5C–D ).

Etymology. From Latin word arbor = tree, and raptor = thief, in reference to the arboreal and predatory habit of the specimens.

Grammatical gender. Masculine.

Distribution. Brazil: Amazonas; Peru: Iquitos ( Fig. 19 ).

Included species. Arboraptor viridis sp. nov. and Arboraptor stigmata ( Nickle, 2003) nov. comb.
