Diagnostic description

Holotype, male (Fig. 9a). Length 4.90 mm. Color black except basal half of elytron bright orange; tarsi and antenna ferruginous. Body elongate; in dorsal aspect with distinct constriction between pronotum and elytron. Rostrum slender, basally scabrous with distinct median ridge and pair of irregular submedian ridges, in apical 1/3 punctate. Pronotum large, subquadrate, densely punctate. Elytra densely punctate with small irregular punctures; striae partly impressed as fine lines, partly indistinct. Femora dentate with acute tooth. Profemur enlarged, subovate, posteriorly concave and polished, in basal third with callus. Metafemur subapically with stridulatory patch. Thoracic and abdominal venter concave, densely punctate, sparsely setose with thin erect setae. Aedeagus (Fig. 9b) with apodemes 3.0 × as long as body; apex rounded, at middle subtruncate; transfer apparatus flagelliform, stout, more than 2 × as long as body; ductus ejaculatorius basally swollen, without bulbus. Intraspecific variation. Length 4.08–4.90 mm. Female rostrum dorsally subglabrous, sparsely punctate, at base coarsely punctate. Male pronotum larger, with sides posteriorly almost straight; female pronotum smaller, with sides rather convex. Male elytra narrower, converging apicad; female elytra wider, lateral contour convex. Female abdominal venter flat, subglabrous, punctate, with sparse short recumbent setae.

Material examined

Holotype (SMNK): ARC1136 (EMBL # HE615765), PAPUA NEW GUINEA, Simbu Prov., Karimui Dist., Haia, Supa, S06°39.905', E145°03.880' to S06°39.796', E145°03.873', 1220–1320 m, 01-X-2009. Paratypes (NAIC, SMNK, ZSM): Simbu Prov., Karimui Dist., Haia, Supa: 2 exx, ARC1137 (EMBL # HE615766), ARC1138 (EMBL # HE615767), same data as holotype; 1 ex, Haia, Supa station, S06°40.047', E145°03.464' to S06°39.905', E145°03.880', 1075–1220 m, 01-X-2009, beaten; 1 ex, Haia, Supa station, S06°39.815', E145°03.169' to S06°39.609', E145°03.012', 1240–1450 m, 30-IX-2009, beaten.

Distribution

Simbu Prov. (Haia). Elevation: 1220–1240 m.

Biology

Collected by beating foliage in montane forests.

Etymology

This epithet is based on the Latin adjective apicalis (pertaining to the apex) and refers to the species´ contrasting elytral coloration.

Notes

Trigonopterus apicalis Riedel, sp. n. was coded as “Trigonopterus sp. 259” by Tänzler et al. (2012)[1].
