Description.
Body black, shiny, with a metallic luster. Surface with spots of pale pink scales. Length: 11.0 – 12.0 mm, width:
5.1 - 5.3 mm
.
Head short, shiny; there is a longitudinal band of pale pink scales and a thin, straight median line between the eyes and the antennal bases. Cheeks without spots. Labrum with dark brown pubescence. Head finely punctate, with metallic luster. Three basal segments of antennae black, two first antennomeres with a bright metallic luster, the third antennomere black (basal part of third antennomere of
D. curculionoides
testaceous), shiny. The fourth antennomere is testaceous basally, with white, very fine pubescence, though the re- maining segments are testaceous and tomentose. Pronotum convex, black, shiny, with metallic luster; laterally sparsely and coarsely punctated. Lateral margin with stripe of pink iridescent scales, without other spots. Scutellum shiny, with metallic luster; rounded and tomentose apically. Elytra convex, black, shiny, with metallic lustre, each elytron with six slightly ovoid spots of pale pink scales, three of which are located dorsally, two laterally and one boot-shaped and apically located. Basal spot located adjacent to the basal margin of the elytra. Apical spot boot-shaped
(
Fig. 2L
). Shoulders of elytra protruberant, shiny. Elytra behind shoulders on both sides without projection, flat. Width of elytra at shoulders:
4.4 – 4.5 mm
. Largest width of elytra behind middle:
5.1 - 5.3 mm
. Elytra with microsculpture, sparse and coarse punctures, and pubescence. Meso-metaepimera and sternites with lateral spots, covered by pale pink or greenish scales. Femora without any small pale pink spot at apex; more or less tomentose. Surface of tarsomeres covered with grey tomentum. Tibia and tarsi apically covered with numerous dark setae.
Differential diagnosis.
According to the body, size and shape of elytral pattern, the new species is similar to
D. curculionoides
Waterh.
(
Fig. 2D, K
), however, the surface pattern is slightly different. The elytra of
D. curculionoides
Waterh.
possesses differently shaped basal, and especially apical (
Fig. 2K, L
), spots. The pronotum of the new species possesses a stripe of pink or greenish scales only along the lateral margin, but in
D. curculionoides
Waterh.
there is a stripe of pink or greenish scales along the side margin and anteriorly there is another small, round spot, covered with similar scales. The third antennomere in
D. gutowskii
sp. n.
is black and shiny, though in
D. curculionoides
Waterh. it
has a testaceous basal part.

Mimicry.
D. gutowskii
sp. n.
possibly mimics the weevil
Pachyrrhynchus erichsoni

Curculionidae

Etymology.
This species is named after my colleague, the Polish entomologist Jerzy Marian Gutowski (Forest Research Institute, Bia³owieaea,
Poland
) in appreciation of cooperation.
