Iquiracetima venturai   sp. nov. ( Figs. 47-50 View Figures 47-50 )

Description: Holotype female:Coloration: Integument mostly dark brown; mouthparts, and posterocentral area

of gulamentum reddish brown; scape brown;pedicel,anterior ⅘ of antennomere III, and basal half of antennomere IV yellowish brown; posterior fifth of antennomere III, posterior half of antennomere IV, and antennomeres V-XI brown. Anterior and posterior areas of prothorax reddish brown (including apex of prosternal process). Elytra with irregular orangish macula on each side of anterior quarter, nearly entirely orangish along suture, and nearly entirely orangish on posterior fifth. Coxae, trochanters, and base of meso- and metafemora reddish-brown; remaining surface of meso-and metafemora, and meso- and metatibiae brown (somewhat dark reddish brown depending on light intensity); tarsi reddish brown.

Head: Frons, vertex, and area behind eyes somewhat coarsely, abundantly punctate; with sparse yellowish-white pubescence on sides of frons and close to upper eye lobes. Genae finely, transversely striate, with sparse punctures interspersed, glabrous. Antennal tubercles somewhat finely,densely punctate,glabrous.Postclypeus with sculpturing as on frons.Labrum with a few long,erect dark setae posteriorly; with dense yellowish setae anteriorly. Gulamentum mostly smooth, glabrous, except for narrow anterior area slightly depressed, micropunctate, and with sparse yellowish-white pubescence. Distance between upper eye lobes 0.62 times length of scape (0.23 times distance between outer margins of eyes); in frontal view,distance between lower eye lobes 1.37 times length of scape (0.50 times distance between outer margins of eyes). Antennae 1.10 times elytral length, reaching posterior fifth of elytra; with yellowish-white pubescence not obscuring integument. Antennomere III slightly sinuous. Antennal formula (ratio) based on length of antennomere III: scape = 0.43; pedicel = 0.21; IV = 0.57; V = 0.32; VI = 0.27;VII = 0.24;VIII = 0.21; IX = 0.21; X = 0.16;XI = 0.21.

Thorax: Prothorax slightly wider than long, with distinct constriction posteriorly. Pronotum strongly convex at anterior ⅘, flat at posterior fifth; slightly, widely longitudinally sulcate on each side of central are in convex area; coarsely, densely punctate; with yellowish-white pubescence close to anterior margin, on flat area (denser and more distinct than on anterior area), and three longitudinal pubescent bands of same color on posterior half, one centrally, another on each side; anterior area with short; remaining surface nearly glabrous. Sides of prothorax with sculpturing as on pronotum; with yellowish-white pubescence not obscuring integument (whiter depending on light intensity). Prosternum and prosternal process coarsely, confluently punctate; with yellowish pubescence not obscuring integument (whiter depending on light intensity).Ventral surface of meso- and metathorax coarsely, abundantly punctate (punctures sparser on center of mesoventrite); with grayish-white pubescence not obscuring integument. Scutellum with dense grayish-white pubescence. Elytra: Coarsely, densely punctate (punctures confluent on some areas); with five elevated longitudinal carinae, first on center of anterior quarter of dorsal surface, one near suture on posterior quarter, only reaching base of orangish posterior area, one dorsally, slightly oblique, from anterior fifth to base of orangish posterior area, one close to lateral curvature, placed on posterior quarter, slightly longer than posteri- or innermost carina, and another on inclined area, small, distinct only on beginning of orangish area; posterior tubercles slightly elevated; with yellowish pubescence not obscuring integument, denser on orangish areas. Legs: Profemora with yellowish-white pubescence dorsally, not obscuring integument, nearly glabrous ventrally except for apex with sparse yellowish-white pubescence; with long, erect, somewhat sparse dark setae on frontal depressed area. Meso- and metafemora and tibiae with yellowish-white pubescence not obscuring integument.

Abdomen: Ventrites with grayish-white pubescence not obscuring integument.

Dimensions in mm: Total length, 4.30; prothoracic length, 0.90; anterior prothoracic width, 0.95; posterior prothoracic width, 0.90; maximum prothoracic width, 1.05; humeral width, 1.30; elytral length, 2.90.

Type material: Holotype female from BRAZIL, Espírito Santo: Aracruz , 19°49′35″S, 40°10′88″W, 02.III.1988, P.M. Vieira col. ( MZSP, formerly SSA).  

Etymology: The new species is dedicated to José Aires Ventura (Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural (Incaper, Espírito Santo, Brazil). After coming from Angola at the beginning of his career, dedicated to various works in the Brazilian state of Espírito Santo, especially in the area of phytopathology.

Remarks: Iquiracetima venturai   sp.nov. is similar to I.egeri Wappes et al., 2017 (see photograph of the holotype at Bezark, 2020),but differs as follows:frons and vertex with slightly conspicuous pubescence (distinct in I. egeri); elytra with irregular orangish macula on anterior region (absent in I. egeri); posterior tubercles of the elytra slightly elevated (strongly elevated in I. egeri); elytral punctures coarser and denser (finer and slightly sparser in I. egeri); anterodorsal innermost carina slightly elevated, not triangular-shaped (triangular shaped in I. egeri). It differs from I. ceruri Galileo & Martins, 2008   (see photograph of the holotype at Bezark, 2020), by the antennomeres V-XI brown (orangish in I. ceruri   ), and elytra without several irregular orangish areas throughout (present in I. ceruri   ).
