Diagnostic description

Holotype, male (Fig. 35a). Length 3.09 mm. Color of antennae ferruginous; tarsi and tibiae dark ferruginous; remainder black. Body elongate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Rostrum slender, dorsally with median carina and pair of submedian ridges; intervening furrows with sparse rows cream-colored scales; subapically sparsely punctate-rugose, epistome indistinct. Pronotum with disk densely punctate; punctures becoming larger towards sides; interspaces between punctures subglabrous, reticulate. Elytra with striae marked by fine hairlines and rows of punctures; intervals 1–3 irregularly punctate with smaller punctures; stria 9 along humerus with seven large, coarse punctures, externally bordered by costa; intervals subglabrous; intervals 2–3 subbasally with patch of recumbent cream-colored scales; subapically intervals 3–7 with another patch of recumbent cream-colored scales; intervals 2–3 behind middle with few scattered scales. Femora edentate. Profemur in basal 1/3 posteriorly with callus. Meso- and metafemur on dorsal edge densely squamose with cream-colored scales; anteroventral ridge simple, distinct. Metafemur subapically with indistinct stridulatory patch. Mesocoxa with dense cluster of erect white scales. Abdominal ventrites 1–2 concave, subglabrous microreticulate, sublaterally with coarse punctures; ventrite 5 with shallow impression, at middle, subglabrous, sublaterally coarsely punctate. Penis (Fig. 35b) with sides diverging, anteriorly converging to subangulate apex, with sparse setae; apodemes 2.3 × as long as body of penis; transfer apparatus symmetrical, spiniform, shorter than lateral guiding pieces; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.51–3.41 mm. Dorsal surface of females rather polished with smaller punctures. Female rostrum more slender, in apical 1/2 subglabrous, dorsally with submedian row of punctures, with sublateral furrow.

Distribution

S-Sulawesi (Gn. Rantemario, Tanah Toraja, Pc. Palopo), C-Sulawesi (Pendolo, Tentena), N-Sulawesi Prov. (Tomohon, Gn. Klabat, Gn. Soputan, Modoinding, Kotamobagu). Elevation 910–1840 m.

Biology

Beaten from lower vegetation of montane forests that often includes tall grasses (e.g., Saccharum sp.). This species may develop in grasses, like some other members of the Trigonopterus honestus-group.

Etymology

This epithet is the Latin adjective inhonestus, -a, -um (disgraceful) and refers to the name of Trigonopterus honestus (Pascoe), a sibling species.

Notes

Trigonopterus inhonestus Riedel, sp. n. was coded as “Trigonopterus sp. 946”. This species is closely related to Trigonopterus honestus (Pascoe) which occurs in North Maluku and can be distinguished by a longer flagelliform transfer apparatus of the male genitalia, by a slightly larger body size, and by the absence of scale patches near the elytral base. It is the only member of the Trigonopterus honestus group currently known from Sulawesi. It occupies a relatively wide range from Mt Rantemario in South Sulawesi to Tomohon in the north. Different populations are genetically structured but appear conspecific.
