Type material. Type specimens of Curculio pupillatus Olivier, 1790 were not found. According to Kuschel (1955), the type material of many species from the Neotropical Region described by Olivier are considered as lost. Images of type material of H. imitatus Voss, 1954 deposited in the ZMH were examined bearing the following labels: Chanchamayo, Peru, A. Heyne Berlin-Wilm.; Heilipus imitatus m.; COTYPUS.; Coll. E. Voss, Eing. 3-75; ZMH 833027.

Non-Type material: The images of non-type specimens of Heilus pupillatus ( Olivier, 1790) deposited in the BMNH, London, Pascoe Collection were examined but specimens did not have any associated label information.

Redescription. Length (pronotum and elytra) of males and females 9.6 to 12.0/ 10.5 to 11.8 mm, respectively.

Integument. Sub-opaque, varying from yellowish-brown to dark brown. Rostrum. About 1.3 times longer than pronotum; in females, about 5.7 times longer than apical width; in males, about 3.8 times longer than apical width.

Thorax. Pronotum ( Figs. 5 View FIGURE 5 A–B) about 1.4 times wider than long, with few rounded granules, arranged approximately in two transverse rows in apical region, and arranged randomly on sides; with fine scales spread evenly, slightly rounded sides with few scales. Elytra ( Figs. 5 View FIGURE 5 A–B). Approximately 1.6 times longer than wide between humeri, moderately convex, with few transverse granules scattered from second interstria, concentrated in basal region until apical elytral calli, smaller and rounded from apical elytral calli to apex; with yellowish or orange scales evenly distributed; extensive whitish macula on sides of elytra, extending from median region to apical elytral calli, between striae 3 and 6, with small velvety black internal macula located on interstria 4; flat interstriae. Male genitalia. Median lobe of aedeagus ( Fig. 18C View FIGURE 18 ) about 1.2 times longer than he median lobe apodemes, apical margin rounded laterally, with slight depression in center; internal sac sclerite trilobate ( Fig. 19B View FIGURE 19 ), with two pointed projections, tiny spicules elongate in center. Tegmen ( Fig. 20B View FIGURE 20 ) with dorsal lobes subequal in length to manubrium; manubrium enlarged at base. Female genitalia ( Fig. 21B View FIGURE 21 ). Coxites robust, elongate; apex of styli with dense, elongate setae. Spermathecal duct of median length inserted into median third of bursa copulatrix. Spermathecal capsule ( Fig. 22B View FIGURE 22 ) sclerotized, with acute curvature, collum elongate, cornu rounded at apex, ramus well-marked.

Dimensions (mm). Males/females, respectively. TBL: 9.6–12/10.5–11.8; TRL: 2.2–3.0/3.9–4.2; MHx: 3.4– 4.2/4.2–4.6; RAW: 0.7/0.7–0.8; RBW: 0.7–0.8/0.7–0.8; IO: 0.2–0.4/0.3–0.4; PnL: 2.3–2.8/2.9–3.3; PnMW: 3.5– 3.7/4.0–4.1; PnBW: 3.2–3.5/3.7–3.9; EL: 6.9–9.4/7.6–8.7; EW: 4.6–4.9/5.1–5.2.

Non-type material examined. In total, 17 specimens were examined. BRAZIL: Amazonas: 1♂, 2.ii.1976, I.S. Coraveb ( INPA) , Itacoatiara , 1♀, 7.xi.2014, Batista, D.G., light trap ( INPA) , Manaus , 1♀, 08.x.1986, Klein, Bert ( INPA) , 1♂, 12.xi.1986, Klein, Bert ( INPA) , 1♀, 23.ix.1986, Luis Ulysses ( INPA) , 1♀, ix.1995, Barbosa, M.G.V., Malaise trap ( INPA) , 1♂, vi.1982, E.

Geographical distribution. Wibmer & O’Brien (1986) presented the geographical distribution of H. pupillatus as French Guiana, Bolivia, Peru, and Brazil. The material examined allows for the first records of this species for the Amazon biome (Amazonas, Pará, Acre, and Rondônia states) ( Fig. 23 View FIGURE 23 ), since Wibmer & O’Brien (1986) cited the species only for Brazil, without specifying the range of distribution within the country ( Fig. 23C View FIGURE 23 ).

Associated plants. Unknown.

Remarks. Heilus pupillatus differs from other species in its irregular and enlarged range of yellowish scales that extends from the humeral region to the apical elytral calli. The synonymy of H. pupillatus , H. imitatus , and H. inclusus follows Kuschel (1955), based on the examination of the last two species, without a taxonomic discussion.
