Paratypes: same collection data as for holotype (1♂: RBINS; 1♂: PCTB); 1♀: [Coll. I.R.Sc.N.B., R. D. CONGO, +/ - 40km E. Kisangani, 17.III/ 04.IV.2017, Th. Bouyer leg.] [Coll. I.R.Sc.N.B., don P. Limbourg, I.G.: 33.944] ( RBINS) .

DESCRIPTION:

Male

Measurements ♂: length: 11–12 mm, width: 6–6.5 mm.

Body: Laterally convex, bent; overall chocolate-brown except clypeus, lateral margins of pronotum and two short patches on disc of elytra yellowish; strongly shining with strong greenish metallic reflections.

Head: clypeus trapezoidal and totally reflexed with irregular punctures, almost coalescent, vertex less punctate between eyes, punctures moderately small, round and separate; frons less punctate. Antennae with 9 antennomeres, with club longer than funicle.

Thorax: pronotum rectangular, wider than long; sides slightly angular in middle; all margins carinate; anterior angles projecting and reaching posterior margin of eyes; with moderately deep rounded separated punctures; scutellar shield semicircular, with small isolated shallow punctures.

Elytra: longer than wide; epipleura complete; regularly striate-sulcate; primary costae more convex than intervals; intervals microreticulate, first and 2 nd with complete secondary striae; striae with close horseshoe-shaped punctures; margins along apex coarsely punctate, rugose; humeral calli slightly marked, apical calli well marked.

Pygidium: triangular, apex rounded, carinate along anal plate, tumid, slightly projecting postero-ventrally and not surpassing apex of elytra; reticulate striolation which is arranged concentrically around the tumidity.

Venter: upper part of metaventrite with close horseshoe-shaped punctures, median part with small isolated rounded punctures; 2 nd to 5 th abdominal ventrites with transversal deep cressent-shaped punctures, 6 th with imbricate puncture.

Legs: protibiae bidentate, larger claw short, ventrally strongly sinuate, shorter than last tarsomere; pro-and mesostarsal larger claw cleft; larger claw of metatarsus slightly longer than smaller one and uncleft.

Hairs: dorsal side with isolated yellowish setae on antennae, on lateral margins of pronotum and on inner part of legs; underside with sparse decumbent short yellowish setae on sides of metaventrite; short erected isolated yellowish setae on coxae, on legs and along carinate of anal

plate; close and longer on anterior and posterior margins of prosternum; abdominal ventrites glabrous.

Aedeagus: in lateral view, parameres rather short and ventrally rounded; in dorsal view, triangular, separated from middle part to apex.

Female

Measurements ♀: length: 13 mm, width: 7 mm.

Differs from ♂ by: clearer colored, yellowish with a slight golden metallic reflection but those specimen could be teneral; larger, laterally more convex and abdomen convex; club of antennae shorter; pygidium projecting postero-ventrally, surpassing apex of elytra; protibiae narrower with apical tooth rounded and longer.

DERIVATIO NOMINIS.

Dedicated to Robert Ducarme (Bruxelles, Belgium).

DISTRIBUTION. Known from Democratic Republic of Congo.

BIOLOGY. The species was collected from December to the beginning of April.

DIFFERENTIAL DIAGNOSIS.

Anomala ducarmei sp. nov. is similar to A. nigrosulcata Candèze, 1869 but can be distinguished as follows:

A. ducarmei sp. nov. A. nigrosulcata ( Figs 9–16 ).

Aedeagus: in lateral view parameres rather short and Aedeagus: in lateral view parameres rather short and ventrally rounded; in dorsal view, triangular, separated ventrally bilobed; in dorsal view, triangular and not from middle part to apex; in ventral view, median lobe separated from middle part to apex; in ventral view, with a raised median fork, apex straight median lobe without a raised median fork, apex

( Figs 5–7). rounded

( Figs 13–15 ).

Lateral margins of pronotum and two short patches on Lateral margins and median line of pronotum disc on elytra yellowish. yellowish, the latter sometimes limited to a fine incomplete line but rarely absent.

♂: length: 11– 12 mm, width: 6 – 6.5 mm; ♀: length: ♂: length: 15 – 17 mm, width: 8.5 – 9 mm; ♀: length: 13 mm, width: 7 mm. 15 – 16 mm; width: 9 – 9.5 mm.
