Diagnostic description
Holotype, male (Fig. 27a). Length 1.48 mm. Color black; antenna light ferruginous; legs deep ferruginous. Body subglobose, in dorsal aspect with marked constriction between pronotum and elytron; dorsally flattened; anteriorly profile almost straight, convex at apex. Rostrum coarsely rugose-punctate; epistome forming distinct, transverse ridge. Pronotum coarsely punctate-reticulate. Elytra with striae deeply incised, with sparse rows of setae; intervals costate, subglabrous, with few minute punctures; interval 7 subapically forming ridge, projecting dentiform; apex subangulate. Legs. Anteroventral ridge of meso- and metafemur ending in apical third, forming indistinct tooth. Metafemur dorsoposteriorly simple, subapically with stridulatory patch. Aedeagus (Fig. 27b) with apex subtruncate, slightly angulate; transfer apparatus spiniform, shorter than body of aedeagus; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.32–2.02 mm. Body of females subovate. Female rostrum dorsally subglabrous, coarsely punctate; epistome simple. Female elytral apex laterally not dentiform.

Distribution
Jayawijaya Reg. (Jiwika). Elevation: 1875–1900 m.
Biology
Sifted from leaf litter in montane forest.
Etymology
This epithet is the latinized form of the Greek word edaphos (soil, ground) and treated as an adjective. It refers to the habit of this litter-dwelling species.
Notes
Trigonopterus edaphus Riedel, sp. n. was coded as “Trigonopterus sp. 224” by Tänzler et al. (2012)[1].
