Female. Integument dark brown. Body covered with short yellowish-white setae. Frons ( Fig. 107 View FIGURES 104 – 112. 104 – 105 ) squared, convex in lateral view. Upper ocular lobes height about 2.5 times smaller than lower ocular lobe; distance between them almost maximum width of lobe. Lower ocular ( Fig. 107 View FIGURES 104 – 112. 104 – 105 ) lobe rounded and salient; height about twice the malar area. Genae convergent.
Antennae ( Fig. 100 View FIGURES 95 – 103 ) reaching elytral apex approximately at antennomere VII. Scape with slight transverse depression on apical fourth at outer surface; 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. 109 View FIGURES 104 – 112. 104 – 105 ) about 1.5 times wider than long; covered with short yellowish-white setae; anterior margin almost one fourth narrower than posterior margin. Pronotum ( Fig. 1 View FIGURE 1. A B; 108) with five tubercles on disc: two median elevated, with robust base and apex oval and glabrous; with elevations posterolateral to median tubercles prominent, appearing as two tubercles, punctate and completely covered with setae; with the fifth tubercle on midline, situated posterior to median tubercles, smaller and with glabrous apex. Prosternal process width almost half 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 yellowish-white setae.
Scutellum wider than long, subtriangular and apical margin truncate; finely punctate and covered with short yellowish-white setae.
Elytra length about 3.8 times longer than prothorax; covered with yellowish-white setae and irregular denser patches of white setae on center of dorsum and apical fourth. Basal-crest ( Fig. 109 View FIGURES 104 – 112. 104 – 105 ) elevated, adorned by a row of six aligned tubercles, rounded and glossy apex; from crests, one “V”-shaped stain of dark brown setae; region between basal-crests with setae of coloration similar to dorsum, except near scutellum, with a rounded macula of dense dark brown setae. Epipleura with slight spot of dark brown setae near margin. Apical margin of elytra with a slight spine in external apical angle.
Legs covered with yellowish-white setae. Meso- and metafemora glabrous on inner surface. Meso- and metafemora with a slight circular spot of dark brown setae on median region at 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 yellowish-white setae, denser laterally and on apical region of last sternite. Sternite V wider than long; almost as long as the length of sternite sII, III and IV together; lateral margins with slight longitudinal depression.
Measurements (mm), female. Total length, 17.7–19.7; prothorax length, 3.3–3.6; prothorax maximum width, 5.7–6.2; elytral length, 13.1–14.7; humeral width, 7.4–7.9.
Type-material. Holotype, Alphus javariensis , female, Estirão do Equador, Amazonas, Brazil (MNRJ); Alphus diringsi Martins & Monné , synonym, holotype, female, Benjamin Constant, Amazonas, Brazil (MZSP).
Discussion. Ateralphus javariensis is similar to A. lucianeae new species and differs by pronotum with five protuberant tubercles (three glabrous, present in all Ateralphus , and two covered by setae), the basal-crest with six aligned tubercles and the meso- and metafemora glabrous on inner surface. Ateralphus lucianeae new species has three protuberant tubercles on pronotum, basal-crests with unaligned tubercles, and inner surface glabrous only on metafemora.
