According to Forel, this variety, taken at Mackay, Queensland(Gilbert Turner), is larger than the type (3.6 mm.) and differs in sculpture as follows: "Abdomen densely punctate and subopaque. All the remainder densely and finely reticulatepunctate and opaque. Moreover, the front is coarsely longitudinally rugose, while the other portions of the head, the thorax and petiole are covered with dense, superimposed foveolae, in part reticulate or transformed into rugae."

A single specimen taken at Sydney, New South Wales (A. M. Lea) agrees with this description.
