Color of mesoscutum: dark brown to black. Sculpture of mesoscutum: rugulose. Notaulus: complete. Visibility of notaulus: unobscured. Parapsidal line: present. Sculpture of mesoscutellum: rugulose. Shape of axillular carinae: without a posteroventral hooklike projection. Color of axillular carina: brown. Sculpture of T3-6: rugulose. Median carina on T1-T4: present.

Diagnosis.

This species can be identified by the dorsal median carina (T1-T4 of metasoma) and can be distinguished from D. subcoeruleus and D. fulgidus by the rugulose sculpture of the mesoscutum.

Etymology.

The epithet comes from the Latin word for “dusky,” referring to the darker, metallic color of the mesosoma (in comparison to D. fulgidus ). This epithet is treated as an adjective.

Distribution.

Papua New Guinea (Madang, Morobe, Northern, East Sepik), Australia (Queensland).
