Type specimens. HOLOTYPE ♂, 6 km NE Barkly Roadhouse , Northern Territory (19.669°S 135.857°E), 7 Aug 2012, M. Batley ex Corymbia terminalis in AM ( K360277 ) . PARATYPES (7♀♀, 8♂♂, all deposited in AM) . 2♀♀, 3♂♂, same data as holotype (K345676–680) , 5♀♀, 5♂♂, 4 km NE Barkly Roadhouse (19.681°S 135.849°E), 7 May 2008, M. Batley, ex Corymbia terminalis (K361456–463) .

Diagnosis. Both sexes recognisable from colour pattern on metasoma.

Description. Female.—Head width 1.1 mm, body length 3.5 mm. Relative measurements: HW 50, HL 39, UID 30, LID 25, FVL 11, CW 25, CL 10, FL 24. Head yellow with occiput black and antenna dark brown dorsally. Frons with weak, dense punctures and weak tessellation. Mesosoma yellow except scutum orange-yellow with darker markings approximately along parapsidal lines, propodeum dorsally black with medial yellow patch, laterally yellow. Scutum with dense punctures and weak tessellation. Metasoma yellow with thick black lines running down the sides and across the rear of each tergum to form a linear pattern of contiguous rectangles.

Male.—Head width 1.1 mm, body length 3.5 mm. Relative measurements: HW 50, HL 37, UID 31, LID 25, FVL 5, CW 23, CL 9, FL 26. As for female, but scutum yellow with irregular faint brown markings.

Etymology. The specific name is a Latin adjective meaning “of a ladder” and refers to the dorsal colour pattern on the metasoma of both sexes.
