Type locality. Pushkar (Rajasthan, India) .

Type series. Holotype: well-preserved, 3.89 mm long dissected male with missing right mesotarsal onychium labeled “PUSHKAR INDIA 16/X/2011 J. H. leg. / coll. J. Haran / HOLOTYPUS Cionus harani sp. n. M.Košťál et R.Caldara des. 2017 [printed red label]” ( MNHN) . Paratype: same labeling as holotype except for “ PARATYPUS ” (1 ♀ HA) .

Description. Male (holotype). Body stout, subrotund to suboval. Head: rostrum moderately slender, medium long (l/ w 5.2, Rl/Pl 1.28), reddish-brown; in lateral view very slightly evenly curved, same width from base to antennal insertion, then moderately tapered to apex; in dorsal view same width from base to apex, basal part slightly laterally constricted, apical part moderately dorsoventrally flattened; texture and vestiture similar to that of C. hortulanus . Head between eyes and eyes as in C. hortulanus . Antennae reddish, inserted at 0.6 of rostrum length; funicle of 0.6 scape length, segment 1 slightly wider than segment 2, 1.5 × as long as wide, segment 2 twice as long as wide, segments 3–5 subglobose to transverse; club oval, slightly more than twice as long as wide, slightly longer than funicle, almost completely covered with recumbent whitish hairs and sparse, relatively short whitish sensilla. Pronotum: brown, somewhat wider than long (Pl/Pw 0.69), texture and vestiture similar to that of C. hortulanus except punctures smaller and median part with semidensely distributed, subrecumbent elongate black scales; widest at base, moderately narrowed to half of its length, then conically narrowed to anterior margin, constricted as in C. hortulanus , in lateral view as in C. hortulanus . Prosternum: anterior margin with bluntly incised shallow semicircular incision bounded by flat shiny tubercles, separated from coxae by very narrow prosternal area. Scutellum: moderately convex, otherwise as in C. hortulanus . Elytra: reddish-brown, outline as in C. hortulanus , moderately elongate (El/Ew 1.16), widest in mid-length, at base strikingly wider than pronotum (Ew/Pw 1.79), humeri subrotund, apparently prominent, with slight posthumeral impression; almost flat on disc; interstriae moderately convex, otherwise texture and vestiture including black tomentous maculae as in C. hortulanus excepting large patches of black scales on humeri; entire surface covered with semidensely arranged, recumbent to subrecumbent, markedly elongate (l/w 6–10), whitish scales concealing majority of integument. Venter: slightly unevenly covered with recumbent, whitish elongate to hair-like scales, wider scales clustered especially on metepisterna, less strikingly on metasternum and ventrite sides; mesosternal process flat, broad, blunt at posterior margin, scaled, densely punctured; metasternum concave, transversally ribbed, ventrite 1 and 2 with deep, transversally ribbed to punctured impression; ventrite 1 1.7 × as long as ventrite 2, ventrites 1–2 combined 6.5 × as long as ventrites 3–4 combined, ventrites 3–4 combined of half length of ventrite 5. Legs: reddish-brown; as in C. hortulanus except for all claws of approximately same length and profemora with more distinct transverse bands. Penis: Figs 18 d–f, its body shorter and wider, rounded at apex.

Female. Rostrum longer (Rl/Pl 1.43), antennae inserted shortly beyond mid-length, apical part of rostrum with sparsely distributed tiny punctures, shiny. Ventrites 1 and 2 without impression. Claws equally long.

Variability. Length ♂ 3.89 mm, ♀ 4.15 mm. The type couple does not show any variability.

Diagnosis. This species is recognizable by almost completely concealed elytral integument, apical part of rostrum flattened in both sexes, in female long and shiny, medium large black tomentous maculae, deep impression on ventrites 1 and 2, antennae with oval club and short funicle, almost equally long claws in males, and penis shape.

Comparative notes. Cionus harani is most closely related to C. hortulanus from which it differs by antennae with oval club and short funicle in both sexes, equally long claws and penis shape in males, punctured apical part of rostrum in females.

Biological notes. Biology unknown.

Distribution. India (Rajasthan).

Etymology. The species is named after its collector and our colleague Julien Haran.

Non-type specimens examined. None.
