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).
Material examined
Holotype, female: Papua New Guinea: NE Finisterre Range, Saidor, Gabumi; OSUC 234417 (BPBM). Paratypes. Australia: 1 male, OSUC 875045 (CNCI). Papua New Guinea: 12 females, 4 males, OSUC 234413–234416, 234422–234424, 234426, 234428–234429 (BPBM), OSUC 875873–875876 (CNCI).
