Type specimens. Holotype ♁: “ Kenya, Tsavo West National Park (03°30´S – 38°16´E), 7.11.2005, G. Curletti & V. Sakalian leg.” . Paratypes 2 exs: 1 ♀ with same locality and date as holotype ; 1 ♀: “western of Voi Town (03°26´S – 38°16´E), 4.11.2005, G. Curletti & V. Sakalian leg.”. The holotype is deposited in IZBAS and the paratypes in GCCI and IZBAS .

Description of holotype. Body elongate, dark copper dorsally, underside and frons with blackish tinge. Elytra with two longitudinal, sutural stripes of short golden pubescence.

Head with medial sulcus on vertex and upper and middle portions of frons; vertex rugose with fine punctation; width of vertex between eyes 0.52 mm; frons very strongly protruding at middle portion; upper and middle portions of frons with deep and dense punctation; lower portion of frons and genae with short, dense, golden pubescence; clypeus without pubescence, separated from frons by deep transverse sulcus, extending between lower portions of eyes; eyes convex and very large; antennae short, extending anterior margin of pronotum; antennomeres 4–11 wider than long, triangular.

Pronotum widest at anterior third; anterior margin slightly bisinuate, carinate; anterior pronotal lobe distinct; lateral margins distinctly curved before latero-posterior angles; latero-posterior angles slightly obtuse; pronotum with four depressions (two lateral and two medial) lateral depressions deep and wide; medial depressions separated at central portion of disc; posterior depression deep, triangular; anterior depression shallow; prehumeral pronotal carinae very short, arched, extending from latero-posterior angles to posterior third of pronotum, widely separated from lateral margins; marginal and submarginal carinae not coalescent; disc rugose, discal sculpture consisting of dense punctation and diagonal and transverse striae.

Scutellum robust, anterior portion triangular; transverse carina present; hind projection short and acutely pointed.

Elytra elongate, subparallel, width across humeri slightly wider than pronotal base, widest at posterior third; humeral depressions deep and large without pubescence; apices very narrowly separately arcuate, not serrulate; elytra with two longitudinal, sutural stripes of short golden pubescence, extended from humeral depressions to apices; remaining elytral pubescence uniform and sparser; elytra not covering laterosternites, visible from dorsal view; discal elytral sculpture consisting of transverse wrinkles.

Figure |4. Aedeagus of Agrilus (Agrilus) polinae , sp. n. (dorsal view). Scale: 1 mm.

Underside. Prosternal lobe robust, emarginate medially. Prosternal process slightly narrowed between procoxae; elongate apically; prosternum and prosternal process with white, short dense pubescence. Suture between ventrites 1 and 2 not visible; ventrites with uniform, short, sparse, white pubescence; laterosternites with very dense, short, white pubescence; apex of last ventrite truncate with very slightly presented medial incision. Metatarsus shorter than metatibia; basal metatarsomere shorter than following metatarsomeres together. Tarsal claws bifid. Aedeagus (Fig. 14).

Description of paratypes. Females more robust with dark cooper frons and bright copper underside, apex of last ventrite without incision; prosternal process more densely pubescent.

Size. Length 4.20–4.85 mm (holotype 4.20 mm); width 1.05–1.35 mm (holotype 1.05 mm).
