Diagnostic description
Holotype, male (Fig. 12a). Length 4.24 mm. Color black; antenna partly ferruginous. Body ovate; in dorsal aspect and in profile with constriction between pronotum and elytron. Rostrum slender, dorsally with distinct median carina and sublateral ridges; furrows bordering ridges containing each one row of mesad directed white narrow scales; subapically shining, punctate, setose. Eyes large. Pronotum large, subglabrous, with minute punctures, in basal half sides separated by densely punctate edge. Elytra punctate with minute punctures; striae impressed as fine lines; basal margin bisinuate, bordered by row of large punctures continued behind humeri. Profemur large, anteriorly at middle with large tooth. Mesofemur and metafemur dorsally densely squamose with white scales; with anteroventral ridge at middle with inconspicuous tooth. Metafemur with smooth dorsoposterior edge; subapically without stridulatory patch. Aedeagus (Fig. 12b) apically weakly pointed; ductus ejaculatorius near insertion to transfer apparatus swollen, subapically with weak bulbus. Intraspecific variation. Length 3.28–4.16 mm. Female rostrum dorsally largely subglabrous, with submedian rows of minute punctures; in basal 1/5 punctate-rugose, with white recumbent scales.

Distribution
Jayapura Reg. (Cyclops Mts). Elevation: 300–1200 m.
Biology
Collected by beating foliage in montane forest.
Etymology
This epithet is based on the Latin noun augur in apposition and refers to the large eyes that help the species to see birds, presumably important predators.
Notes
Trigonopterus augur Riedel, sp. n. was coded as “Trigonopterus sp. 21” by Riedel et al. (2010)[1] and Tänzler et al. (2012)[2], respectively “Trigonopterus spu” in the EMBL/GenBank/DDBJ databases.
