Diagnostic description
Holotype, male (Fig. 52a). Length 2.94 mm. Color black; antennae light ferruginous, legs deep ferruginous. Body subovate; with weak constriction between pronotum and elytron; in profile evenly convex. Rostrum in basal half with distinct median ridge and pair of submedian ridges, furrows with sparse rows of yellowish scales; apically weakly punctate, sparsely setose. Pronotum coarsely punctate-reticulate. Elytra with dense, somewhat confused punctation; striae distinct, impressed as very fine lines, strial punctures small; intervals with slightly smaller punctures; laterally behind humeri simple. Femora edentate. Metafemur with denticulate dorsoposterior edge, with sparse row of suberect silvery scales; subapically with stridulatory patch. Metatibia apically with uncus and minute premucro. Abdominal ventrite 5 with shallow impression, densely punctate, with dense suberect scales. Aedeagus (Fig. 52b) with sides in apical 1/3 converging, weakly rounded, sparsely setose; transfer-apparatus spiniform; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.53–3.20 mm. Female rostrum dorsally subglabrous, sparsely punctate, in basal ¼ with longitudinal ridges and furrows. Elytral sculpture differing markedly among populations: striae weakly or hardly impressed in specimens from Eastern Highlands; distinctly impressed in specimens from Pindiu; deeply incised forming well-defined furrows in specimens from Mindik.

Etymology
This epithet is based on a combination of the Latin noun mons (mountain) and the participle vagus (wandering) and refers to the relatively wide distribution in the highlands of Papua New Guinea.
