Agrilus carinelytratus Jendek, sp. nov.

Figs. 31, 55, 74

Diagnosis. This species is very distinctive by the very long humeral carinae extending to the epipleural apex.

Description (Holotype): Body form, color and pubescence as in Fig. 31. Head and eyes feebly convex; eyes not protruding from head outline. Pronotum markedly convergent apically, widest at basal half, sides subparallel in basal half, arcuately convergent in apical half; apical pronotal margin distinctly narrower than basal margin; anterior pronotal lobe large and slightly projecting beyond anterior pronotal angles; posterior angles subrectangular; pronotal disk markedly convex, with distinct, oval, prescutellar impression; lateral impressions absent; prehumerus long, extending beyond half of pronotal length, sharply costate, rectilinear in basal half, feebly arcuate to margin in apical half, apex distant from marginal carina (lateral view).

Elytra with obvious humeral carinae extending to apical end of epipleuron, monochromatic golden-green combined with bichromatic yellowish and white ornamental pubescence; apices narrowly, separately, subangulately arcuate.

Prosternum (Fig. 55): Prosternal lobe large, subtruncate, slightly bent at margin; prosternal process broad, with moderately, rectilinearly expanded sides, disk faintly impressed, lateral corners somewhat protruding ventrad. Basal part of intercoxal process with spinuliform protrusion medially; basal abdominal ventrite without tubercles; apex of last abdominal ventrite distinctly emarginate.

Aedeagus (Fig. 74).

Length. 3.9–4.0 mm, Holotype 3.9 mm.

Sexual dimorphism. Female has prosternal process flat with uniplanar lateral angles, lacking spinuliform protrusion on interxocal process.

Variability. Paratypes are golden-bronze, with pronotal sides slightly emarginate before subacute basal angles.

Type series. Holotype 3 (EJCB): “ Malacca Perak W. Doherty”. Paratypes (2 exs): 1 Ƥ (EJCB): “Perak Malacca (Doherty)”; 1 Ƥ (EJCB): “ Malaysia, Pahang distr., 30km NE Raub, Lata Lembik, 3º56'N,; 101º38'E, 200–400 m, 22.IV.–1.V., 8–15.V.2002, E. Jendek & O. Šauša leg.”. Type locality. Malaysia, Melaka state, Malacca [= Melaka, 102°15'E, 02°12'N].

Distribution. Mainland Malaysia: Melaka, Pahang.

Etymology. The name is a compound word derived from the Latin word carina (keel-like part or ridge) and Greek elytra (one of the pair of hardened forewings of certain insects) to stress the very long humeral carinae of this species.
