Ateralphus lucianeae new species

( Figs. 103 ; 106; 113–115; 130)

Female. Integument dark brown. Body covered with dense and short greenish-gray setae. Frons rectangular, convex in lateral view. Upper ocular lobes height almost half of lower ocular lobe; distance between them about 1.5 times width of lobe. Lower ocular lobe rounded and truncate at posterior margin; height about twice the malar area. Genae convergent.

Antennae ( Fig. 103 ) reaching elytral apex approximately at antennomeres VII–VIII. Scape with slightly depressed ring on apical fourth; covered with sparse yellowish-white setae speckled aspect. Pedicel with one spot of dark brown setae on apical region. Antennomeres III–XI with one ring of dark brown setae on apical region, gradually longer on distal antennomeres; antennomeres III and IV with one fringe of straight setae on inner surface.

Prothorax ( Fig. 106 ) about 1.5 times wider than long; covered with short greenish-gray setae; anterior margin almost one fifth narrower than posterior margin. Pronotum with three tubercles on disc: two median elevated, pyramidal-shaped and glabrous apex; with the third tubercle on midline, situated posterior to median tubercles, smaller and with glabrous apex. Prosternal process width almost one third the diameter of one procoxa. Mesosternal process flat at posterior half and anterior margin decline at an angle of approximately 45° relative to mesosternum. Mesepisternum, mesepimeron and metepisternum covered with gray setae.

Scutellum ( Fig. 106 ) wider than long, subtriangular and apical margin truncate; finely punctate and covered with dense gray setae.

Elytra length about 3.7 times longer than prothorax; covered with rather greenish-gray setae interspersed by patches of white setae slightly pronounced. Basal-crest elevated, adorned by small tubercles irregularly distributed; from crests, one “V”-shaped stain of dark brown setae; region between basal-crests with evident punctation and covered with sparse dark brown setae, denser near scutellum, not encircling it completely. Epipleura with slight longitudinal stripe of dark brown setae near margin. Apical margin of elytra truncate.

Legs entirely covered with greenish-gray setae. Metafemora glabrous on inner surface. Meso- and metafemora with a slight circular spot of dark brown setae at median region on anterior surface. Tibiae with dense ring of dark brown setae interspersed with golden setae on apical third. Tarsomere V bicolorous, base with yellowish-white setae and apex dark brown.

Abdomen entirely covered with greenish-white setae, denser laterally and on apical region of last sternite. Sternite V wider than long; almost as long as the length of sternite II, III and IV together.

Terminalia ( Figs. 113–115 ). Sternite VIII ( Fig. 113 ) subcylindrical, with apical region slightly narrower than basal region; sternal apodeme length about 3.5 times longer than sternite VIII. Tergal apodemes concave and narrowing towards basal region. Coxites ( Fig. 115 ) narrow and elongate, parallel and near each other; basal region about four times wider than apical region. Bursa copulatrix ovate. Spermathecal duct long. Spermatheca elongate and curved, with rounded apex. Spermathecal gland long, length about four times than spermatheca.

Measurements (mm), female. Total length, 13.7–14.3; prothorax length, 2.8–2.9; prothorax maximum width, 4.7–5.0; elytral length, 10.3–11.0; humeral width, 5.8–6.2.

Etymology. The species is named after Dra. Luciane Marinoni (DZUP) in recognition of her great support during the development of this work.
