Male. Integument of head, prothorax and ventral surface dark brown. Body covered with dense and short greenishwhite setae. Frons rectangular, convex in lateral view. Upper ocular lobes height almost half of the 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. 101 ) reaching elytral apex approximately at antennomere VI. Scape integument, greenishbrown; with slightly depressed ring on apical fourth and covered with white setae. Pedicel with one spot of dark brown setae on apical region. Antennomeres III and IV almost completely covered with dark brown setae on outer surface, with intumescence at inner apex and one fringe of straight setae on inner surface; antennomeres V–XI with one ring of dark brown setae on apical region, gradually longer on distal antennomeres.

Prothorax ( Fig. 111 ) about one third wider than long; covered with short white setae; anterior margin almost one fifth narrower than posterior margin. Pronotum with three tubercles on disc: two median elevated, pyramidalshaped and glabrous apex; with the third tubercle on midline, situated posterior to median tubercles, smaller and with glabrous apex; with one faint elevation posterolateral to median tubercles covered with setae. 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 golden brown setae.

Scutellum ( Fig. 111 ) wider than long, subtriangular and apical margin truncate; with one slight longitudinal depression on median region; finely punctate and covered with dense golden brown setae, such as circumscutellar region.

Elytra integument greenish-brown; length about 3.6 times longer than prothorax; covered with greenish-white setae interspersed by pronounced patches of white setae. Basal-crest elevated, adorned by small tubercles; from crests, one “V”-shaped stain of dark brown setae; region between basal-crests covered with light brown setae which covers scutellum, forming a circumscutellar macula. Epipleura ( Fig. 112 ) with longitudinal stripe of dark brown setae well-marked near margin. Apical margin of elytra truncate.

Legs integument greenish-brown; covered with white setae. Femora integument brown in basal half and greenish in apical half. Meso- and metafemora ( Fig. 112 ) glabrous on inner surface and with strong circular spot of dark brown setae at median region on anterior surface. Tibiae with dense ring of dark brown 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; length shorter than sternites II, III and IV together.

Terminalia. Median lobe ( Figs. 116–117 ) curved in lateral view; dorsal and ventral lobes subequal in height and apex truncate; basal apophysis as long as apical portion; Tegmen ( Fig. 118 ) as long as median lobe; parameres length about 2.5 times less than tegmen lenght; ring pieces together at apex, with one apical projection curved and apical margin truncate.

Female. Antennae ( Fig. 102 ) reaching elytral apex approximately at antennomeres VII–VIII; antennomeres III and IV without intumescence apically.

Sternite V length equal to or longer than sternites II, III and IV together.

Terminalia ( Figs. 119–121 ). Sternite VIII ( Fig. 119 ) subcylindrical, with median region rounded; sternal apodeme length about three times longer than sternite VIII. Tergal apodemes concave and narrowing towards apices. Coxites ( Fig. 121 ) robuste and elongate, parallel and near each other at apical region; basal region about four times wider than apical region. Bursa copulatrix elongate, oval and with prominence at median region. Spermathecal duct long. Spermatheca elongate, gradually wider towards apical region and apex rounded. Spermathecal gland long, length about five times than spermatheca.

Variability. Elytral tegument vary from greenish to brown. The intumescence at inner apex and the fringe of straight setae on inner surface of male antennae, although less pronounced and may be present after antennomeres II and IV. Several specimens examined have inner margin of profemora glabrous.

Measurements (mm), male/female. Total length, 10.3–15.7/10.2–14.5; prothorax length, 2.2–3.4/2.0–2.7; prothorax maximum width, 3.2–5.2/3.4–4.7; elytral length, 7.3–11.5/7.5–10.8; humeral width, 4.0–6.5/4.3–6.2.

Type-material. Holotype, Alphus canescens Lacordaire (not Bates), male, Rio de Janeiro, Brazil (BMNH) (examined by photograph).

Discussion. This species is similar to A. senilis and A. lucianeae new species. May be differentiated from A. senilis by characteristics in the discussion of that species and from A. lucianeae new species for region between the basal-crests, densely covered with dense brown setae that wraps scutellum, while A. lucianeae new species has sparse dark brown setae not wraping the scutellum. Furthermore, in A. dejeani , the longitudinal stain of dark brown setae on epipleura and the circular macula on meso- and metafemora are denser and more evident than those in other mentioned species.

Geographical distribution. Brazil (Bahia, Minas Gerais, Espírito Santo, São Paulo, Rio de Janeiro, Paraná, Santa Catarina and Rio Grande do Sul). New records are added from Brazil (Goiás), Argentina (Misiones) and Paraguay (Alto Paraná) ( Fig. 130 ).

Biology. According to literature, the larva develops in Annona squamosa L. ( Annonaceae ) (Galileo & Martins, 2006b).
