Description

This species is externally very similar to D. liebherri sp. nov. Its description will therefore be differential and limited to diagnostic characters.

Habitus and colour. – Fig. 4d. Fully winged. Body length: 11.5-12.1 mm. Legs wholly testaceous, including femora (which are consistently darker than the tibiae in D. liebherri sp. nov.).

Head. – Neck narrower, eyes bigger, almost hemispherical; antennae longer and slenderer, the first antennomere 3.4 times longer than wide ( 2.5 in D. liebherri sp. nov.).

Prothorax. – Lateral margins of the pronotum narrower.

Elytra. – Separately projecting into a triangular apex with a blunt tip (rounded in D. liebherri sp. nov.). Elytral dorsal surface more irregular, with a well impressed transverse microsculpture; umbilicate series of only 16 setiferous punctures ( 18-20 in D. liebherri sp. nov.).
