TYPE MATERIAL.
ZAMBIA. Holotype ♂: [Coll. I.R.Sc.N.B., ZAMBIA N.W., 70km NE of Kapiri, 27.xi.2005, M. Snížek lgt., I.G.: 31.208] (RBINS).
Paratype: 1♀: [Coll. I.R.Sc.N.B., ZAMBIA NW, 92km NW Mpika, 27.xi.2005, lgt. M. Snížek, IG: 31.208] (RBINS).
DESCRIPTION.
MALE. Measurements: length: 9.5 mm, width: 4.5 mm.
Body: laterally convex, relatively elongate, slightly bent, broader in middle of elytra; abdomen concave; perpendicular process at base of prosternum rounded, spinose process on third abdominal ventrite, second ventrite with crater-shaped structure; yellowish with head, all margins, tarsi and spines on outer sides of legs reddish-brown; teeth of protibiae, apex of upper lip and 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 longer than funicle.
Thorax: pronotum rectangular, wider than long; sides uniformly rounded from base to apex; all margins with complete marginal line; anterior angles slightly projecting and reaching posterior margin of eyes; with shallow horseshoe-shaped punctures, almost coalescent on sides; impressed point on lateral margins; scutellar shield subobtuse, with rounded apex, with shallow, horseshoe- shaped punctures.
Elytra: longer than wide; epipleura complete; primary costae 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, slightly 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, shorter than last tarsomere, mesotarsal outer claw cleft; outer claw of metatarsus two times longer than inner and uncleft.
Setation: dorsal side covered with short, white squamous decumbent setae; long, widely spaced, erected, yellowish setae from lateral margins of pronotum to declivity of elytra, on antennae and on canthus; underside with short, white, squamous decumbent setae; sparse, long, decumbent brownish-yellow setae inserted in setigerous punctures; close, long, decumbent yellowish-brown setae along anterior and posterior margins of prosternum; longer, white, erected squamous setae on disc of pygidium; long, erected, yellowish-brown setae on base of labium; outer sides of legs with short, white squamous, decumbent, setae, inner sides with long, erected, brownish-yellow setae inserted in setigerous punctures.
Aedeagus: in lateral view, parameres elongate and straight; in dorsal view lateral margins of parameres curved, apex strongly notched at apico-internal angle, left process shorter.
FEMALE: Measurements: length: 10.5 mm, width: 5 mm.
Differs from ♂ by: larger body; laterally more convex and abdomen convex; no spinose process on second and third abdominal ventrites; antennae with club as long as funicle; pygidium slightly projecting postero-ventrally and not surpassing apex of elytra; protibiae narrower with apical teeth longer.
DERIVATIO NOMINIS.
Dedicated to the late Robert F. Kennedy for his civil rights position.
DISTRIBUTION.
Known from Zambia.
BIOLOGY.
The species was collected in the month of November.
DIFFERENTIAL DIAGNOSIS.
Adoretus kennedyi sp. nov. is similar to A. depressusoides Limbourg, 2019 but can be distinguished as follows:
A. kennedyi sp. nov. (Fig. 13)
Aedeagus: in dorsal view, lateral margins of parameres curved.
Male with a spinose process on third abdominal ventrite, second ventrite with a crater-shaped structure.
A. depressusoides Limbourg, 2019 (Figs 13–14)
Aedeagus:in dorsal view, lateral margins of parameres almost parallel.
Male with a spinose process on second and third abdominal ventrite.
