Agrilus nalandae Théry

(Figs. 1, 34)

nalandae Théry, 1904: 162 –163. Obenberger, 1936: 1093.

Diagnosis. This species resembles species related to A. livens Kerremans, 1892 by the color and elytral patterns, but it differs from them by the large eyes, presence of prehumerus, the markedly attenuate elytral apices and by the robust prosternal lobe and prosternal process. Agrilus nalandae is similar to A. aurosus by the body shape, elytral pubescence, and incised prosternal lobe, although it differs from it by the characters given in the key.

Length. 4.9 mm.

Agrilus aurosus Descarpentries & Villiers Figs. 2–3, 35, 58

aurosus Descarpentries & Villiers, 1963: 105, 110.

Diagnosis. This species belongs to the group of species having a slender body, larger head and narrow elytral apices ( A. nalandae, A. rolciki, A. cuneatus). It is similar to A. nalandae by the elytral patterns and to A. ventrituber by having tubercles on the basal abdominal ventrite in males.

Length. 5.0– 7.2 mm.

Variability. Elytra bichromatic, with black (Fig. 2) or bronze (Fig. 3) background blended with goldengreen or golden-violet patterns. Elytral pubescence monochromatic gold, or a bichromatic combination of gold and white. The basal part of body with the pubescence often caducous.
