53. Trigonopterus moreaorum Riedel sp. n.

Diagnostic description.

Holotype, male (Fig. 53a). Length 3.76 mm. Color black. Body elongate-subovate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Rostrum slender; dorsally punctate-rugose, with distinct median ridge and pair of submedian ridges; apical 1/3 sparsely punctate; at base with erect white elongate scales, apically replaced by bristles. Eyes large, medially approximate. Pronotum densely punctate, each puncture containing one short seta; basally with indistinct lateral edge, in basal half contours of disk subparallel; sides anteriorly with few scattered white scales. Elytra subglabrous; irregularly punctate with minute punctures; basal margin with distinct ridge extending behind humeri, bordered by row of coarse punctures. Femora with acute tooth at middle. Mesofemur and metafemur dorsally densely squamose with narrow white scales. Metafemur with smooth dorsoposterior edge; subapically without stridulatory patch. Meso- and metatibia with rows of long erect setae. Venter with sparse pubescence of long suberect setae. Metaventrite and abdominal ventrites 1-2 medially forming common concavity.
