Diagnostic description
Holotype (Fig. 23a). Length 3.22 mm. Color black; antenna and tarsi ferruginous. Body subrhomboid, with marked constriction between pronotum and elytron; in profile convex. Rostrum with median ridge and pair of submedian ridges; intervening furrows with rows of coarse punctures each containing one mesad directed seta; base dorsally protruding, markedly projecting from profile subangularly; epistome posteriorly with transverse ridge. Forehead coarsely punctate-rugose. Pronotum with sides converging to apex, almost without subapical constriction; foveate-reticulate; each fovea containing one inconspicuous seta; interspaces subglabrous, weakly microreticulate. Elytra cuneiform, from broad rounded humeri markedly converging to narrow apex; base bisinuate; surface microreticulate; striae deeply incised, narrow; intervals flat to weakly costate, with 1-2 rows of small punctures; sutural interval subglabrous except few punctures near base; intervals 2-5 behind middle with inconspicuous transverse patches of narrow recumbent scales. Legs. Femora densely punctate. Profemur with subbasal callus anteriorly projecting. Tibiae subbasally with dorsal angulation; pro- and metatibia subapically with suprauncal denticle. Abdominal ventrites 1-2 laterally swollen, medially forming common cavity; ventrite 5 coarsely punctate, weakly concave. Penis (Fig. 23b) with sides of body subparallel; apex subtruncate; endophallus with pair of subtriangular sclerites; transfer apparatus long spiniform; ductus ejaculatorius with distinct bulbus. Intraspecific variation. Length 2.04–3.53 mm. Female rostrum dorsally somewhat flattened; median ridge and pair of submedian costae subglabrous; epistome simple. Female abdominal ventrite 5 flat.

Distribution
Queensland: Cairns, Kuranda, Lamb Range, Mt. Formartine South, Cape Tribulation, Daintree N.P., Cedar Bay N.P., Mt. Webb.
Biology
Sifted from leaf litter in primary forest.
Etymology
This species is named in honor of Geoff Monteith (Brisbane), who collected the majority of the new Australian Trigonopterus species for the first time and whose help was essential for the success of this study.
Notes
Trigonopterus monteithi Riedel, sp. n. was coded as “Trigonopterus sp. 553”.
