Color of mesoscutum: dark brown to black. Sculpture of mesoscutum: punctate with longitudinal striations between notauli. Notaulus: complete. Visibility of notaulus: unobscured. Parapsidal line: present. Sculpture of mesoscutellum: punctate. Shape of axillular carinae in lateral view: without a posteroventral hooklike projection. Color of axillular carina: brown.

Diagnosis.

Dichoteleas rugosus can be distinguished from D. striatus by its setose and punctate mesosoma and other Dichoteleas by its bidentate mandibles.

Distribution.

Australia (Queensland).

Material examined.

Holotype, male, D. rugosus : Australia: QLD, Mackay ; OCT-1897, B.M. TYPE HYM. 9.496.; Australia: 4 females, 2 males, OSUC 367523, 367536 (ANIC), OSUC 875046-875047, 875871-875872 (CNCI).

Comments.

In the original description, Kieffer (1907) wrote that D. rugosus was missing parapsidal lines. They are present but obscured by the sculpture of the mesoscutum.
