Type material. Heilipus myops Boheman, 1836: we examined the image of the holotype (Fig. 9), undetermined sex, bearing the following label “Typus; Brasilia Freyreiss; Heilipus myops Bhn; NHRS–TOBI 000003219”, deposited in the NHRS.
Redescription. Length (pronotum and elytra) of males and females 10.8 to 11.1/ 9.8 to 10.8 mm, respectively. Integument sub-opaque, varying from yellowish-brown to black. Rostrum about 1.2 times longer than pronotum.
Thorax. Pronotum (Figs. 9 A–B) about 1.3 times wider than long, few rounded granules, sparse in approximately two transverse rows in apical region and arranged randomly on sides; with fine scales spread evenly, laterally with few scales. Elytra (Figs. 9 A–B) about 1.5 times longer than wide, moderately convex, few transverse granules scattered from second interstria, and more concentrated from basal region to elytral callosity; yellowish or orange scales distributed evenly, sub-rounded brown to black macula wrapped by row of clear scales between striae 3 to 6 or 7, located in center of elytra; elytral striae with fine punctures forming continuous lines, flat interstriae. Male genitalia. Median lobe of aedeagus (Fig. 18G) with rounded sides, short and not condensed setae at apex; median lobe apodemes about 1.4 times longer than median lobe; internal sac sclerite (Fig. 19F) with bisinuate apex, inserted at end of internal sac, covered with very fine and elongate setae. Tegmen (Fig. 20F) with dorsal lobes and elongate manubrium; manubrium about 1.3 times longer than dorsal lobes. Female genitalia (Fig. 21F). Coxites with short setae at apex; styli transverse. Spermathecal duct short inserted into end of bursa copulatrix. Spermathecal capsule (Fig. 22F) curved, slightly rough on inner margin near to collum, ramus slightly developed, with wrinkles; cornu strongly curved, with rounded apex; spermathecal gland very elongate, about 1.9 times longer than bursa copulatrix, similar width from base to apex.
Dimensions (mm). Males/females, respectively. TBL: 10.8–11.1/9.8–10.8; TRL: 3.1–3.6/3.3–3.7; MHx: 4.5–5.3/4.8–5.2; RAW: 0.7–0.8/0.7–0.8; RBW: 0.7–0.8/0.7–0.8; IO: 0.4/0.3–0.4; PnL: 2.7–2.8/2.7–2.9; PnMW: 3.7–3.8/3.5–3.8; PnBW: 3.7/3.3–3.6; EL: 8.0–8.3/7.1–8.1; EW: 5.3–5.4/4.8–5.2.

Geographical distribution. Heilus myops occurs in Brazil (Wibmer & O’Brien 1986), in the Atlantic Forest (Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, and Paraná states) (Fig. 23G).
Associated plants. Bondar (1925; 1936; 1939) recorded H. myops causing damage to new shoots and fruits of cocoa (Theobroma cacao L. [Malvaceae]) in Bahia, without mentioning the specific location.
