Description.
Total length
14.6–14.8 mm
. Body metallic green, elytra almost black, antennomeres 1–3, tarsi and genital segment, brown; antennomeres 4–11 red.
Head
. Oval, posteriorly narrowed (
Fig. 14
), 1.38x as long as wide; dorsal surface a little convex, ventral surface clearly convex; with very dense umbilicate punctures on dorsal surface and moderately dense umbilicate punctures on ventral surface separated by 2–3x their width (
Fig. 23
); temple without temporal carinae, with a concave area slightly deep (
Fig. 29
); eyes 0.31x as long as head, interocular distance 0.64x cephalic width; first antennomere 1.91x as long as antennomeres 2–3 combined, apical antennomere 1.22x as long as antennomeres 9–10 combined; labrum with 4 teeth, central pair larger than lateral pair (
Fig. 55
); mandibular external channel poorly developed; apical maxillary palpomere conically elongate (
Fig. 39
), 1.5x as long as preapical palpomere; apical labial palpomere with apex slightly widened and flattened (
Fig. 44
), near twice as long as preapical palpomere.
Thorax
. Pronotum 1.66x as long as wide; as wide as head; with dense fine punctures except for wide longitudinal impunctate area; without depressed areas at each side of posterior third (similar to
Fig. 52
). Elytra 1.08x as long as pronotum; with fascia of pale, long setae wider than scutellum and similar setae on posterior borders (similar to
Fig. 5
). Transverse prosternum, covered with setae sparser than on meso and metasternum.
Abdomen
. Densely covered with pale, long setae, mainly on borders of each segment.
Aedeagus
. Ovally elongate, base of median lobe widened; total length
3.8 mm
; parameres 0.2x as long as median lobe, not reaching apex of median lobe; apical area of median lobe 0.23x as long as total length of median lobe and internal sac with sclerotized structures (
Fig. 73
).
Variation.
Slight variation in total body length and in metallic color.
Comparison.
This species can be confused with the remaining metallic species of this group but the absence of carinae on the temple of head, the slightly deep concave area, the fascia of setae on elytra wider than the scutellum, the posteriorly narrowed head and the oval aedeagus with base of median lobe widened and short parameres, permit recognition of this species from the others.
Etymology.
The species name is derived from the Latin word “fascia”, and refers to the band of pale, long setae on the anterior third of the elytra.
Geographic distribution.
