Type specimens. Holotype ♁: “ Tanzania, Mikumi 18– 21.07.2001, K. Novák leg.” . Paratype ♀: with same locality and date as holotype. Th e holotype is deposited in IZ- BAS and the paratype in GCCI.

Description of holotype. Body slender, elongate, black colored; elytra with uniform, dense, white pubescence.

Head with deep longitudinal striae on vertex and upper portion of frons; width of vertex between eyes 0.42 mm; frons protruding, rugose with sparse, white pubescence; clypeus separated from frons by sharp, transverse carina; clypeus glabrous; eyes large and convex; antennae short, extending anterior portion of pronotum; antennomeres 4–11 wider than long, rhomboidal.

Pronotum widest at anterior third; anterior margin slightly bisinuate, carinate; anterior pronotal lobe wide, weakly developed; lateral margins subparallel, slightly curved before latero-posterior angles; latero-posterior angles slightly obtuse; pronotum with two deeper lateral depressions and two shallow medial depressions; prehumeral pronotal carinae distinct, arched, extending from latero-posterior angles to posterior third of pronotum, not reaching lateral margins; marginal and submarginal carinae coalescent at posterior third of pronotum; discal sculpture consisting of diagonal and transverse striae; pronotum sparsely pubescent.

Scutellum with anterior margin rounded; transverse carina present.

Elytra elongate, width across humeri almost as wide as pronotal base; elytra widest at posterior third; humeral depressions deep; apices narrowly, separately arcuate, feebly serrated; surface with uniform, dense, white pubescence; discal sculpture consisting of transverse wrinkles.

Underside. Prosternal lobe slightly arcuate. Prosternal process slightly narrowed between procoxae, apical projection long and acutely pointed; prosternum and prosternal process with dense, semierect, white pubescence. Suture between ventrites 1 and 2 not visible; apex of last ventrite truncate, with long, erect setae. Metatarsus shorter than metatibia; basal metatarsomere slightly shorter than following metatarsomeres together. Aedeagus (Fig. 12).

Description of paratype. Female with apex of the last ventrite less rounded, more truncate, with short pubescence, dispersed over entire surface not concentrated in apical portion, without long, erect apical setae, prosternal process, with shorter pubescence.

Size. Length 4.00– 4.55 mm (holotype 4.00 mm); width 1.00– 1.20 mm (holotype 1.00 mm).

Differential diagnosis. Agrilus (Agrilus) roscidellinus Obenberger, 1935 from Tanzania resembles this species in size, black color, uniform white pubescence on elytra and prehumeral carinae not reaching the lateral margin of the pronotum. Agrilus (Agrilus) novaki , sp. n. differs mainly by the glabrous pronotum and frons, broader vertex, rounded head and feebly serrate elytral apex.

Etymology. Dedicated to honor the collector of the specimens K. Novák.
