Etymology. The specific epithet is in reference to the morphological character of the sclerotized ridges present on the metafemora. The name is formed from the Latin denticulatus (with small teeth).
Description. Length 1.60–1.67 mm. Body about 2.3× longer than wide. Dorsal surface piceous to brunneous with contrasting testaceous antennae, mouthparts, and legs. Dorsal vestiture biseriate, clothed with thin, decumbent pubescence arising anterad of each puncture, about 2× length of puncture, with 2–3 additional thin, slightly shorter, suberect setae between each puncture pair. Ventral vestiture with same type of biseriate pubescence as dorsum. Head, HW 0.44–0.45 mm, HL 0.18–0.21 mm; surface with numerous deep, elongate punctures, unevenly spaced on vertex, separated by an average of the length of two punctures, present from basal margin to antennal insertions, absent from integument between antennal insertions. Antennae (Fig. 8B) with scape rounded, slightly longer than pedicel; pedicel subglobular, apex wider than base of antennomere 3; antennomeres 3–10 subserrate; antennomere 3 longer than pedicel, subequal in length and width to antennomere 4; antennomeres 4–7 subequal in length; antennomere 8 shorter than 7, antennomere 9 slightly shorter than 8, antennomeres 9 and 10 subequal; antennomere 11 2× longer than 10; antennomeres 3–11 covered in moderately dense, suberect pubescence, without additional pilosity. Pronotum, PW 0.36–0.38 mm, PL 0.32–0.33 mm. Elytral length 1.8–1.9× elytral width and 4.0–4.2× pronotal length.
Females. Length 1.67–1.69 mm, HW 0.42–0.45 mm, HL 0.17–0.21 mm, PW 0.36–0.38 mm, PL 0.32–0.33 mm, EW 0.74–0.78 mm, EL 1.35–1.36 mm. Antennae with scape rounded, slightly longer than pedicel; pedicel subglobular, apex wider than base of antennomere 3; antennomeres 3–5 subequal in length and width; antennomere 6 subequal in width and slightly shorter than antennomere 5; antennomere 7 subequal in width and slightly shorter than antennomere 6; antennomere 8 subequal in width and slightly shorter than antennomere 9; antennomeres 8–10 subequal in length and width; antennomere 11 subequal in width and about 2× length of antennomere 10.
