Heilipus gibbus, sp. nov.

Figs. (1–34)

Description. Integument subopaque to opaque, blackish. Tarsi, tibiae (except proximally) and base of femora reddish brown. Antennal scape and funicle reddish brown to dark brown. Prothorax and elytra on each side with one stripe of closely set white scales changing to ochraceous scales on elytral declivity (Figs 1–2, 7–8, 9–10); rarely entire white stripe intermixed with ochraceous scales (Fig. 7–8); inner and outer margins of stripe irregularly indented. Head, basal half of rostrum, dorsal region of femora, and lateral sides of thorax with ochraceous scales (Figs. 2, 8, 10, 12). Ventrites almost glabrous, with a few sparse whitish and ochraceous setiform scales (Fig. 6).

Length (rostrum excluded): males: 12.7 ̶15.7 mm; females: 15.6 ̶19.4. Rostrum of males and females conical, curved and gibbous at base, gibbosity more pronounced in males; slightly broader and longer, about as long as pronotum in males (Figs. 3, 4), about 1.1 ̶1.2 times as long as pronotum in females (Fig. 11, 12); antennal insertion pre-median 0.33 ̶0.36 (male), 0.33 ̶38 (female); basal 2/3 with sparse, recumbent elongate oval ochraceous scales, with sparse and large punctures; distal 1/3 glabrous, with finer punctures. Head with irregular, not dense patches of elongate oval ochraceous scales, denser between eyes and radiating from deep rounded median fovea (Figs. 3, 11). Eyes dorsally separated by distance equal to diameter of 21ommatidia (Figs. 3, 11). Antenna: article I of antennal funicle 1.6 ̶1.7 times (males) (Fig. 4) and 1.9 ̶2.0 times (females) (Fig. 11) as long as article II; club elongate oval, about 2.1 ̶2.2 times as long as wide and as long as funicular article V ̶VII together (males and females).

Prothorax (males and females) about as long than wide (1.0 ̶1.1), apex strongly constricted, apical margin rounded, lateral sides gently curved, strongly bisinuate at base; pronotal disc weakly flattened in basal 2/3, slightly elevated at anterior third, and with a low, shining and smooth median carina; with a few scattered deep punctures, each one bearing a small elongate creamy scale (Figs, 1, 7, 9).

Elytra (males and females) (Figs. 1, 2, 7 ̶10) 2.6 ̶2.8 times longer and 1.35 ̶1.50 times wider than pronotum, and 2.0 2.1 times as long as wide; sides subparallel in basal 3/4, then narrowing towards apex, conjointly rounded, widest near anterior fourth (due to protuberant callosity on stria 9), declivital calli rounded and very prominent, distally with glabrous areas, but with patches of elongate oval creamy scales; intervals flat, integument subopaque, microrugose (50X); punctures of striae very small, each puncture bearing a minute, elongate oval creamy scale (Figs. 1, 2; 7 ̶10).

Legs: profemora with large acute tooth, inner edge of tooth rounded (Fig. 5, 13), smooth, not crenulated, femora clothed with sparse ochraceous elongate oval scales, more concentrated on dorsum and lateral sides; tibiae with inner margins strongly bisinuate, almost glabrous, with a few whitish setiform scales.

Abdomen. Ventrites (Figs. 6, 14). Wing binding-patch formed by two oval granulose elevated surfaces of lateral sides of tergites VII and VI (Figs. 26, 32, 34).

Male genitalia (Figs. 15–19): median lobe of aedeagus (Figs.15, 16) arcuate, slender, about 3 times as long as wide, largest width near basal fourth, sides anteriorly subparallel and abruptly converging to rounded anterior margin, asetose; apodemes about as long as median lobe; internal sac with mictrotrichiae but without large sclerites. Tegmen (Fig. 17–18) apex of manubrium (or apodeme) truncate. Sternite IX (Fig. 19) with spiculum gastrale very slender, evenly curved.

Female genitalia (Figs. 20 ̶23) Sternite VIII (Fig. 23) V-shaped, apodeme very short, apex with anterior margin truncate. Coxites short (Fig. 21), about 3.0 times as long as wide; styli cylindrical, setose, elongate, about 2.0 times as long as wide, articulated preapically; spermatheca (Fig. 22) with capsule well sclerotized, sickleshaped, apex rounded, branches of similar size, gland lobe (ramus) and duct lobe (collum) about same length and approximate, gland of spermatheca rounded. Bursa copulatrix without sclerites.

Sexual dimorphism slight, females on average more robust than males; rostrum of females proportionately longer, slender and with a lower basal gibbosity. Ventrites I and II with median depression deeper in males (Fig. 6) than in females (Fig. 14). Ventrite V slightly convex, apex transversely depressed in males females (Figs. 6, 14). Posterior margin of tergite VII with a V- shaped notch at middle (Fig. 26) but straight in female (Fig. 32).

Males with elytro-tergal stridulatory apparatus (Figs. 24 ̶29); file (pars stridens) located in ventral subapical surface of elytron, files of right and left elytra similar, formed by ridges parallel to elytral margin (Figs. 24, 25, 27); plectrum formed by tubercles placed on dorsum of tergite VII (Figs. 26, 28, 29). Stridulatory apparatus absent in females; region corresponding to file in males with integument granulose, not forming ridges (Fig. 30, 31, 33); dorsum of tergite VII smooth (Figs. 32, 34).

Etymology. Latin gibbus, in reference to the humped rostrum of males and females.

Geographic distribution. From central Brazil (DF) (Junqueira et al. 2000) through southwestern Brazil (states of Minas Gerais and São Paulo) to southern Brazil (state of Santa Catarina).
