description
DESCRIPTION. MALE. Measurements: length: 13 – 14.5 mm, width: 7 mm. Body: laterally convex, elongate, slightly bent, broader in middle of elytra; abdomen concave; perpendicular process at base of prosternum pointed; yellowish-brown with head yellowish-brown to reddish-brown; all margins, tarsi and spines on outer sides of legs reddish-brown; teeth of protibiae, apex of upper lip, apex of mandibles blackish; slightly shiny. Head: broad; clypeus rounded, entirely reflexed, totally covered with tubercles; vertex with isolated tubercles; antennae with 10 antennomeres, with club slightly longer than funicle. Thorax: pronotum rectangular, wider than long; sides uniformly rounded from base to apex; all margins with complete marginal line; anterior angles projecting and reaching posterior margin of eyes; with shallow, horseshoe-shaped punctures, almost coalescent on sides; scutellar shield subobtuse, with rounded apex, with shallow, horseshoe-shaped punctures. Elytra: longer than wide; epipleura complete; primary costae slightly more convex than interstices; all secondary striae irregularly punctate with horseshoe-shaped punctures; striae formed by a line of close small, horseshoe-shaped punctures; humeral and apical calli slightly marked. Pygidium: triangular, apex rounded, marginated along anal plate, imbricate-punctate; not projecting postero-ventrally and not surpassing apex of elytra. Venter: lateral part of metaventrite with large transversal crescent punctures, middle part almost smooth; lateral part of abdominal ventrites imbricate-punctate, middle part almost smooth. Legs: protibiae tridentate and relatively slender, inner claw elongate and cleft, slightly shorter than last tarsomere, mesotarsal outer claw cleft, longer than last tarsomere; outer claw of metatarsus one third longer than inner and uncleft. Setation: dorsal side covered with relatively close, short, white, squamous decumbent setae; long, widely spaced, erected yellowish setae from lateral margins of pronotum to median part of elytra, on antennae and on canthus, close to declivity of elytra; underside with short, white, squamous decumbent setae on metaventrite and abdominal ventrites; lines of long, erected, brownish-yellow setae inserted in setigerous punctures on abdominal ventrites; close, long, decumbent yellowish-brown setae along anterior and posterior margins of prosternum; long, whitish, erected setae on disc of pygidium; longer, erected, yellowish-brown setae on base of labium; outer sides of tibiae with short, white, squamous decumbent setae; inner sides with erected, brownish-yellow setae and long, erected brownish-yellow setae inserted in setigerous punctures on margin. Aedeagus: in lateral view, parameres elongate and ventrally straight, upwards curved in the third part, dorsally sinuate; in dorsal view, lateral margins of parameres almost parallel, apex spatulate and slightly sinuate in the middle. FEMALE: Measurements: length: 14 mm, width: 7 – 7.5 mm. Differs from ♂ by: laterally more convex and abdomen convex; antennae with club shorter; pygidium slightly projecting postero-ventrally and not surpassing apex of elytra; protibiae narrower with apical teeth wider and longer. DERIVATIO NOMINIS. Dedicated to the late Belgian entomologist Vincent Allard (1921 - 1994), specialist of Afrotropical Cetoniinae.

diagnosis
DIFFERENTIAL DIAGNOSIS. Adoretus (Adoretus) allardi sp. nov. is similar to A. ictericus Burmeister, 1844 but can be distinguished as follows: A. (Adoretus) allardi sp. nov. (Fig. 11) Aedeagus: in lateral view, parameres elongate and ventrally straight, upwards curved in the third part, dorsally sinuate; in dorsal view, lateral margins of parameres almost parallel, apex spatulate and slightly sinuate in the middle. Hairs: close long erected yellowish setae along declivity of elytra. A. ictericus Burmeister, 1844 (Figs 11 – 12) Aedeagus: in lateral view, parameres more elongate and ventrally curved; in dorsal view, subtriangular elongated shaped, apex strongly sinuate in the middle. Hairs: long widely spaced erected yellowish setae along elytra.
