Diagnostic description
Holotype, male (Fig. 19a). Length 2.75 mm. Color of antennae and legs ferruginous; remainder black with bronze luster. Body subovate; in dorsal aspect with weak constriction between pronotum and elytron; in profile dorsally flat, convex to apex. Rostrum dorsally with median carina and pair of submedian carinae; intervening furrows with sparse rows of suberect yellowish scales; epistome short, indistinct; base of rostrum swollen, in profile dorsally convex, arching over forehead. Pronotum laterally with distinct subapical constriction; disk densely punctate; interspaces subglabrous, reticulate; with subglabrous median ridge. Elytra densely punctate with small punctures; striae indistinct; intervals with rows of small punctures; subbasally and subapically with sparse yellowish scales. Hind legs long. Femora edentate; anteroventral ridge distinct, weakly crenate; anterior surface punctate-reticulate, each puncture with narrow scale. Metafemur dorsally weakly denticulate, with row of erect clavate scales; subapically with stridulatory patch. Metatibia curved, subapically with few long setae. Thoracic venter and abdominal ventrites 1–2 sparsely setose with long erect setae. Abdominal ventrite 5 at middle with subglabrous concavity, basal margin at middle with short extension. Penis (Fig. 19b) with sides of body in basal 1/2 subparallel, subapically widened; apex sparsely setose, with median, subtriangular extension; apodemes 2.4 × as long as body of penis; transfer apparatus flagelliform, ca. 1.5 × length of body of penis; ductus ejaculatorius with indistinct bulbus. Intraspecific variation. Length 2.60–2.75 mm. Female rostrum dorsally flattened, with ridges less distinct. Female thoracic and abdominal venter subglabrous. Female abdominal ventrite 5 flat.
Material examined
Holotype (MZB): ARC3227 (GenBank # MK260432), S-Sulawesi Prov., Mangkutana, 02°20.203'S 120°46.878'E, 903 m, sifted, 14-V-2013. Paratypes (SMNK): 2 exx, ARC3225 (GenBank # MK260431), ARC3226 (GenBank # MK260433), same data as holotype. Other material examined: 1 ex, ARC3209 (EMBL # LN884975), C-Sulawesi Prov., Pendolo, Gn. Sampuraga, 02°12.165'S 120°45.567'E, 934 m, sifted, 13-V-2013.
Distribution
S-/C-Sulawesi Prov. (Mangkutana, Pendolo). Elevation 900–930 m.
Biology
In leaf litter of montane forest.
Etymology
This epithet is a combination of the Latin adjective curvus, -a, -um (curved, bent) and the noun pes (foot, leg). It refers to the curved metatibia. A noun in apposition.
Notes
Trigonopterus curvipes Riedel, sp. n. was coded as “Trigonopterus sp. 480”. The form “480-A” represented by a female specimen from Pendolo differs ca. 11% p-distance of cox1 and may represent a separate species.
