Diagnosis. Large (7.2–9.2 mm), wedge-shaped, convex ( Fig. 3 ); dorsal surface bronze, frontoclypeus and tips of elytra with red lustre, lateral elytral depressions with silky lustre; dorsal surface asetose, frons with dense, erect, white pubescence; ventral surface lustrous, bright bronze with short, sparse, recumbent, white pubescence; prosternal process with dense (in male nearly lanuginose), erect pubescence; ventral pubescence distinctly denser on metacoxae, metepisterna, laterotergites and on posterior margin of metasternum.

Description. Male (holotype). Head large, as wide as anterior pronotal margin; frontoclypeus widely emarginate anteriorly, frons slightly convex; vertex very weakly convex, 0.8 times as wide as width of eye; eyes large, reniform, not projecting beyond outline of head; sculpture of frons consisting of very small, dense, polygonal cells with indistinct central grains; antennae short, scarcely reaching midlength of lateral pronotal margins when laid alongside; scape long, claviform, slightly curved, 4.5 times as long as wide, pedicel suboval, 1.2 times as long as wide; third antennomere subtriangular, 1.5 times as long as wide, fourth antennomere obtusely triangular, as long as wide; antennomeres 5–10 trapezoidal, slightly wider than long; terminal antennomere rhomboid, about as long as wide.

Pronotum rather convex, 1.7 times as wide as long, with very shallow lateroposterior depressions; anterior margin deeply, posterior margin very slightly biarcuate, lateral margins regularly rounded; maximum pronotal width in anterior third, posterior angles obtuse; pronotal sculpture consisting of ¿ne, transverse rugae which are laterally bent, directed at anterior angles, and of small, polygonal cells with tiny central grains along lateral margins. Scutellum flat, obtusely pentagonal to cordiform, slightly wider than long.

Elytra convex, slightly uneven, strongly wedge-shaped, 1.9 times as long as wide; posterior half of each elytron with longitudinal depression near lateral margin; humeral swellings large but not projecting beyond elytral outline, basal, transverse depressions wide, shallow, not reaching scutellum; each depression interrupted in middle by small tubercle; elytral epipleura narrow, nearly parallel-sided, not reaching elytral apex; elytral sculpture consisting of ¿ne punctures which are somewhat transversely widened on basal part and along lateral margins.

Ventral surface lustrous, rather densely, ¿nely punctate; prosternal process flat, enlarged posteriad procoxae, sharply pointed apically; anal ventrite widely truncate, ¿nely but sharply serrate laterally ( Fig. 16 ). Legs rather robust, short, protibiae rather strongly curved, mesotibiae slightly curved without inner serration, metatibiae straight with large tooth in posterior fourth of inner margin ( Fig. 20 ). Tarsal claws small, regularly arched, only very slightly enlarged at base.

Aedeagus ( Fig. 9 ) long and slender, only slightly bent dorsoventrally, parameres tapering posteriorly; median lobe sharply pointed apically, without lateral serration.

Sexual dimorphism. The female differs from the male in slightly stouter body, less trapezoidal terminal antennomeres, sparser and shorter pubescence of the prosternal process, unmodi¿ed metatibiae and widely notched anal ventrite ( Fig. 17 ).

Measurements. Length: 7.2–9.2 mm (holotype 9.2 mm); width: 2.8–3.2 mm (holotype 3.2 mm).

Variability. Nearly no variability was observed except for the size; one male paratype (road Kiserian–Oltepesi) possesses green-bronze antennomeres 6–11 and narrow, green stripe along the inner margins of eyes.

Etymology. This species is named after the collector of the holotype, our friend and colleague Edo Jendek (Ottawa, Canada), a world specialist in the genus Agrilus Curtis, 1825 .

Differential diagnosis. Anthaxia (H.) jendeki sp. nov. is somewhat similar to A. (A.) nigroaenea sp. nov.; except for the characters given in the key it differs from it in smaller body, bronze colouration, unicolour antennomeres of male, distinctly S-shaped inner margins of eyes, slightly different pronotal sculpture, form of the male metatibiae ( Figs 20 vs. 21) and in the different male genitalia ( Figs 9 vs. 10).

Distribution. Kenya (Rift Valley Province).
