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.

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.
Trigonopterus strombosceroides Riedel, sp. n. was coded as “Trigonopterus sp. 37” by Riedel et al. (2010) and Tänzler et al. (2012), respectively “Trigonopterus spak” in the EMBL/GenBank/DDBJ databases.
