Distribution

Aulacus burwelli is known from the type locality, Table Unio road ( Jennings et al. 2004), and from Katalupaik ( Fig. 12B ).

Remarks

During the 2017 “Our Planet Reviewed” expedition, 11 females were collected in Malaise traps at Katalupaik, 110 km north-west of the type locality ( Fig. 12B ). These females range from 4.1 to 5.9 mm in total length. Based on these new specimens, the variability of color pattern of A. burwelli is: pronotum from completely yellow to yellow with the dorsal half brown; median lobe of mesoscutum from orange with a basal and transverse black stripe to orange with the basal half almost completely black; lateral lobes of mesoscutum from black to orange with a median black stripe; scutellum from black to black with two lateral orange spots; coxa III from yellow with base black to almost completely black with a variable amount of orange anteriorly and posteriorly; metasoma from largely orange with variable amount of black, especially dorsally, to almost black with some orange laterally; wings hyaline with the apex slightly infuscated; venation brown with pterostigma lighter medially.
