Diagnostic description

Holotype, male (Fig. 34a). Length 2.15 mm. Color black; legs and rostrum deep ferruginous; antenna light ferruginous. Body laterally somewhat compressed, ovate; without constriction between pronotum and elytron; in profile evenly convex. Rostrum dorsally in basal third with low median ridge and pair of submedian ridges; apically subglabrous. Eyes large. Pronotum densely punctate; dorsally punctures small, laterally larger, each with one minute seta; without scales. Elytra dorsally subglabrous, stria 1–2 hardly visible; laterally strial punctures large, relatively shallow. Femora with anteroventral ridge. Profemur converging from base to apex. Meso- and metafemur with dorsoposterior edge in apical third shortened; metafemur subapically without stridulatory patch. Tibiae simple, without rows or brushes of long setae; metatibia subapically with small suprauncal projection. Metaventrite laterally forming acute process over metacoxa, reaching tibial insertion. Metaventrite and abdominal ventrite 1 subglabrous, with sparse recumbent setae. Abdominal ventrite 2 similar to ventrites 3–4. Abdominal ventrite 5 with transverse depression, without distinct cavity; subapically with median denticle. Aedeagus (Fig. 34b) apically sinuate, with deep median incision; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.98–2.48 mm. Female abdominal ventrite 5 almost flat, densely punctate.

Material examined

Holotype (MZB): ARC0441 (EMBL # FN429152), WEST NEW GUINEA, Jayapura Reg., Cyclops Mts, Sentani, S02°32.2', E140°30.4', 545–700 m, 02-XII-2007, beaten. Paratypes (ARC, SMNK, ZSM): WEST NEW GUI-NEA, Jayapura Reg., Cyclops Mts, Sentani: 38 exx, ARC0442 (EMBL # FN429153), ARC0443 (EMBL # FN429154), same data as holotype; 1 ex, ARC0653, S02°32.3', E140°30.4', 350–620 m, 19-XI-2007, beaten; 2 exx, S02°31.8', E140°30.5', 600–900 m, 28-XI-2007; 2 exx, S02°32.0', E140°30.4', 700–900 m, 02-XII-2007; 4 exx, S02°31.6', E140°30.4', 900–1100 m, 28-XI-2007, beaten; 11 exx, 950–1450 m, 03-X-1992; 21 exx, 600–1000 m, 05-X-1991; 2 exx, 800–1000 m, 07-VIII-1992; 6 exx, 300–1400 m, 10-VIII-1991; 5 exx, 400–800 m, 07-VIII-1992; 4 exx, 350–850 m, 16-X-1996; 1 ex, 300–550 m, 02-X-1992.

Distribution

Jayapura Reg. (Cyclops Mts). Elevation: 620–950 m.

Biology

Collected by beating foliage in primary forests.

Etymology

This epithet is based on the Latin noun granum (small kernel, seed) in apposition and refers to the general habitus.

Notes

Trigonopterus granum Riedel, sp. n. was coded as “Trigonopterus sp. 15” by Riedel et al. (2010)[1] and Tänzler et al. (2012)[2], respectively “Trigonopterus spo” in the EMBL/GenBank/DDBJ databases. It is closely related to Trigonopterus pseudogranum sp. n., Trigonopterus velaris sp. n., and Trigonopterus imitatus sp. n.; from the latter two it can be distinguished by its sparsely punctate body and the structure of its male abdominal ventrite 5. The externally very similar Trigonopterus pseudogranum sp. n. is best separated by the cox1-sequence which diverges 12.1 %.
