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 View FIGURES 1 – 8 , 9–10 View FIGURES 9 – 14 ); rarely entire white stripe intermixed with ochraceous scales ( Fig. 7–8 View FIGURES 1 – 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 View FIGURES 1 – 8 , 10, 12 View FIGURES 9 – 14 ). Ventrites almost glabrous, with a few sparse whitish and ochraceous setiform scales ( Fig. 6 View FIGURES 1 – 8 ).

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 View FIGURES 1 – 8 ), about 1.1 ̶1.2 times as long as pronotum in females ( Fig. 11, 12 View FIGURES 9 – 14 ); 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 View FIGURES 1 – 8 , 11 View FIGURES 9 – 14 ). Eyes dorsally separated by distance equal to diameter of 21ommatidia ( Figs. 3 View FIGURES 1 – 8 , 11 View FIGURES 9 – 14 ). Antenna: article I of antennal funicle 1.6 ̶1.7 times (males) ( Fig. 4 View FIGURES 1 – 8 ) and 1.9 ̶2.0 times (females) ( Fig. 11 View FIGURES 9 – 14 ) 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 View FIGURES 1 – 8 ̶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 View FIGURES 1 – 8 ; 7 ̶10).

Legs: profemora with large acute tooth, inner edge of tooth rounded ( Fig. 5 View FIGURES 1 – 8 , 13 View FIGURES 9 – 14 ), 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 View FIGURES 1 – 8 , 14 View FIGURES 9 – 14 ). Wing binding-patch formed by two oval granulose elevated surfaces of lateral sides of tergites VII and VI ( Figs. 26 View FIGURES 24 – 29 , 32, 34 View FIGURES 30 – 34 ).

Male genitalia ( Figs. 15–19 View FIGURES 15 – 19 ): median lobe of aedeagus ( Figs.15, 16 View FIGURES 15 – 19 ) 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 View FIGURES 15 – 19 ) apex of manubrium (or apodeme) truncate. Sternite IX ( Fig. 19 View FIGURES 15 – 19 ) with spiculum gastrale very slender, evenly curved.

Female genitalia ( Figs. 20 View FIGURES 20 – 23 ̶23) Sternite VIII ( Fig. 23 View FIGURES 20 – 23 ) V-shaped, apodeme very short, apex with anterior margin truncate. Coxites short ( Fig. 21 View FIGURES 20 – 23 ), 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 View FIGURES 20 – 23 ) 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 View FIGURES 1 – 8 ) than in females ( Fig. 14 View FIGURES 9 – 14 ). Ventrite V slightly convex, apex transversely depressed in males females ( Figs. 6 View FIGURES 1 – 8 , 14 View FIGURES 9 – 14 ). Posterior margin of tergite VII with a V- shaped notch at middle ( Fig. 26 View FIGURES 24 – 29 ) but straight in female ( Fig. 32 View FIGURES 30 – 34 ).

Males with elytro-tergal stridulatory apparatus ( Figs. 24 View FIGURES 24 – 29 ̶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 View FIGURES 24 – 29 ); plectrum formed by tubercles placed on dorsum of tergite VII ( Figs. 26, 28, 29 View FIGURES 24 – 29 ). Stridulatory apparatus absent in females; region corresponding to file in males with integument granulose, not forming ridges ( Fig. 30, 31, 33 View FIGURES 30 – 34 ); dorsum of tergite VII smooth ( Figs. 32, 34 View FIGURES 30 – 34 ).

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