Description. Body length 3.03–3.31 mm, holotype 3.19 mm. Appressed scales on pronotum and elytra irregularly short oval, slightly imbricate, 4–6 rows across width of one elytral interval (Figs 1, 2); scales on head, on scapes, femora and tibiae distinctly smaller than those on elytra; scales light brownish with weak pearly sheen (Fig. 1). Elytra with low tubercles across surface, each with one inconspicuous, short, erect piliform setae placed on top; length of each seta shorter than half width of interstria; pronotum and head with rostrum with similar setae, sparsely irregularly scattered; scapes, femora and tibiae with short, erect setae; funicles with erect, moderately long setae; clubs densely finely setose; tarsi with short semi-erect setae.
Rostrum (Fig. 3) 1.05–1.08× wider than long, at base 1.11–1.16× wider than at apex, epifrons 1.18–1.22 × wider than long.
Antennal scape (Figs 1, 3) curved at midlength, in basal half slender, in apical half faintly evenly enlarged apicad, at apex 0.6–0.7× as wide as club, 0.7–0.8× as long as protibia, 1.4–1.5× longer than funicle. Funicle article 1 1.9–2.0× longer than wide and 1.3–1.4× longer than article 2, this is 1.6–1.7× longer than wide; articles 3–6 1.3–1.4× wider than long; article 7 1.2–1.3× wider than long; club 1.4–1.5× longer than wide.
Pronotum (Fig. 1) 1.41–1.45× wider than long, 0.62–0.68× as wide and 0.25–0.29× as long as elytra, with laterally directed, rounded and moderately projected lobes. Disc with ill-defined, low, longitudinal median keel along basal two thirds, enlarged just before base to low rounded elevation and lowered between keel and lateral lobes.
Elytra (Fig. 1) 1.21–1.29× longer than wide.
Tarsomere 2 1.4–1.5× wider than long; tarsomere 3 1.4× wider than long and 1.4–1.5× wider than tarsomere 2; onychium 1.9–2.0× longer than tarsomere 3; claw as long as tarsomere 3.
Penis (Fig. 6) 2.5× longer than wide, in dorsal view subparallel-sided, with slightly rounded sides, apex lengthened to moderately long slender tip, with distinctly concave sides; in profile weakly regularly curved, tip lengthened, straight; endophallus at rest (Fig. 6), with complex of three basal hook-shaped endophallites and two long, approximate, sickle-shaped endophallites in apical part. Spermatheca (Fig. 9) with almost straight cornu; ramus robust, about as long as wide, apically tapered; collum subtriangular, about as long as ramus, apically lengthened to slender tip.
Etymology. This species is named ‘tuberculata’ after the low, elytral tubercles.
