Variability in the color of the legs, antennae, and mandibles loosely correlates with size: smaller specimens tend to be darker. Th is species is unlikely to be confused with <i>O. scapularis</i> or <i>O. rostratus</i>, both of which are elongate species. However, larger specimens often appear similar to <i>O. alluaudi,</i> and while the characters that separate them are numerous, they can be subtle. Th e preocellar pit is absent in females of <i>O. naevus</i> and is found very rarely in males as a small depression. Females of <i>O. alluaudi</i> always have a preocellar pit (Fig. 15), but it may be small and difficult to see. <i>Oreiscelio naevus</i> has an anterior pit of the pronotum that is small (Fig. 10) and the posterior margin of the ventral pronotum lacks a percurrent sulcus (Fig. 10). <i>Oreiscelio alluaudi</i> has a large, somewhat conspicuous, anterior pit of the pronotum (Fig. 9), and the sulcus along the posterior margin of the ventral pronotum extends around the antespiracular patch (Fig. 9). <i>Oreiscelio naevus</i> lacks a median keel on S1 (Fig. 86) and has a setose ventral cell of the metapleural triangle (as in Fig. 5). <i>Oreiscelio alluadi</i> has a thin, straight median keel on S1 (Fig. 31) and the ventral cell of metapleural triangle has at most 3 very small setae (Fig. 6). <b>Etymology.</b> The epithet <i>naevus</i>, meaning “birthmark”, refers to the patch of smoother sculpture on the lateral mesoscutum. <b>Link to distribution map.</b> <b> 43</b> <b>Material examined.</b> Holotype female: <b>MADAGASCAR</b>: 22°37.60’S 45°21.49’E, Prov.
