Name
Trigonopterus strombosceroides Riedel sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnostic description
Holotype, male (Fig. 84a). Length 2.75 mm. Color black; tarsi and antenna ferruginous. Body elongate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Rostrum with longitudinal ridges and rows of coarse punctures, with sparse suberect scales; epistome flat, with small punctures. Pronotum with marked subapical constriction, anteriorly densely punctate; disk deeply sculptured, with median ridge and pair of broad submedian ridges; ridges densely punctate; behind constriction anteriorly with pair of lateral angular protrusions. Elytra with striae deeply incised; with sparse narrow cream-colored scales; intervals irregularly costate, with rows of small punctures, along two transverse bands depressed; apex rounded. Femora edentate. Metafemur with weakly denticulate dorsoposterior edge, subapically with stridulatory patch. Tarsomere 3 small, hardly larger than preceding, onychium ca. 1.5 X longer than tarsomere 3. Abdominal ventrites 1–2 with common impression; abdominal ventrite 5 concave, tomentose. Aedeagus (Fig. 84b) apically subtruncate, without setae; with asymmetrical transfer apparatus; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.75–2.93 mm.

Distribution
Jayapura Reg. (Cyclops Mts). Elevation: 945–1265 m.
Biology
Sifted from leaf litter in primary forest.
Etymology
This epithet is a combination of the name Stromboscerinae and the Latin ending -oides (having the form of) and refers to the species´ resemblance in habitus with members of this subfamily of Dryophthoridae.
Notes
Trigonopterus strombosceroides Riedel, sp. n. was coded as “Trigonopterus sp. 37” by Riedel et al. (2010)[1] and Tänzler et al. (2012)[2], respectively “Trigonopterus spak” in the EMBL/GenBank/DDBJ databases.
