11. Craspedophorus lemariei new species

(VIII. Plate 7 , Fig. 58, Fig. Plate 8 , Fig. 68a, Plate 9 , Fig. 68b, Plate 13 , Fig. 111)

Type locality. “ Lac Zonanghé [=Onague Lake], Gabon ”.

Type material. Holotype (♂): “ Lac Zonanghé / Gabon. Afr. c / ing. Lemarie [printed in black on white label]”( Plate 7 , Fig. 58, NMPC) . Paratypes. 1♂,1♀ labeled same as holotype (cMH).

Description of holotype. Length 18.6 mm, width 7.0 mm. Proportions: Pronotum 1.44x wider than long, 2.09x wider than head with eyes, elytra 1.23x wider than pronotum, 1.56 longer than wide.

Colouration. Body throughout piceous black, not too glossy, densely covered with black setae. Femora black, genae, tarsi, antennae, palps and mandibles brownish. Each elytron with two dark yellow maculae, humeral macula reaching from VI to VIII interval overlapping to IX., elytral margin black, macular spot on VI interval short, laterally widening into the shape of an equilateral triangle. Preapical macula rounded, extending from VI to VIII interval.

Head long, quadrangular, labrum and mandibles smooth, glossy. Terminal labial palpomere prolonged, kidneyshaped (male). Eyes convex. Front flat in the middle, indistinctly protruded upwards, distinctly irregularly punctuated, in front of eyes with two longitudinal depressions, lateral in the form of a thin ridge running from the antennal base to anterior margin of eye (supra-antennary ridge), medial very weak, almost indistinct and wide from anterior margin of eye to clypeus base, coarsely and irregularly punctuated and furrowed. Vertex transversally slightly buckled and punctuated, coming without strangulation into smooth occiput and neck. Antennae whipshaped, distally not widening nor flattening, overlapping half of the body length. The basal antennomere (scapus) twice longer than the second, the third twice longer than the first, the fourth only weakly shorter than the first, surface covered with short setae, more setae cumulated at the distal end of the antennomere ( Plate 8 , Fig. 68a).

Pronotum not too transverse (length/width ratio 1.44), cordiform; anterior pronotal margin straight, parallel to base in its middle, straight part as long as neck is wide, laterally changing into anterior angles, rounded and distinctly protruded forward, lateral margins towards the center widely curved, maximum width behind mid-length, from there narrowing towards base with strong sinuosity, in front of posterior angles with mild incisure, posterior angles rectangular, posteriorly very weakly prolonged to elytral base, only indistinctly overlapping it. Base straight at the center, at the margins up to one fourth indistinctly angled towards elytral humeri without any peduncle. Pronotal disc slightly convex, separated by a weak depression from wide lateral rims which are distinct already from the anterior pronotal margin, the rim posteriorly distinctly widening, elevated upwards along the entire length, the greatest elevation in the basal fourth, then the rim flattening, thus posterior angles jutting out weakly backwards and upwards, not to the sides, without being keel-like. Disc and basal impressions grossly and irregularly punctured, less densely than frons, elevated lateral pronotal margins punctured grossly as well, the punctuation in the basal fourth distinctly finer. Dorsal surface covered with long black setae ( Plate 8 , Fig. 68a).

Elytra fused, convex, ovoid, widening to midlength, then narrowing, maximum width at midlength. Disc symmetrically convex without any distinct collar-like depression. Humeri weakly rounded and bevelled, but distinct, elytral base without any distinct rim. Elytra margined with a flattened rim, regularly and grossly punctured longwise, without widening. Striae deep, regularly punctured. Intervals convex, distinctly punctuated in two, rarely in three lines. Intervals with almost smooth surface inbetween punctuations. Microsculpture indistinct ( Plate 9 , Fig. 68b). Elytra sparsely covered with dark setae which are shorter than those covering pronotum.

Underside covered with short setae, finely punctured medially, coarsely punctured near margins; metepisterna rhombic, as long as wide. Legs moderately covered with black setae.

Aedeagus ( Plate 13 , Fig. 111) is similar to that in C. phenacoides n. sp. ( Plate 13 , Fig. 110).

Differential diagnosis. The species mostly resembles C. ruficrus ( Chaudoir, 1861) , i. e. species known also from Gabon and Equatorial Guinea. It resembles Chaudoir´s lectotype in its size, in the shape of its body and its pronotum, in the elytral colouration, but differs from it in the sculpture, which is somewhat more grossly punctuated on its pronotum and completely different, markedly much deeper and more grossly punctured on its elytra ( Plate 9 , Figs 67b, 68b).

Etymology. Named after RNDr. Ing. Jaroslav Lemarie (1899-1978), assistant professor at the Departement of Forest Protection and Wildlife Management at Mendel University in Brno ( Czech Republic) and collector of the species.

Distribution. Onague lake in Gabon. Known only from the type locality.
