Jones, 1976. The original descriptions of these six species all refer to the antenna as 4-segmented but the published illustrations in these descriptions all show the antenna as 3-segmented. The terminal segment of the antenna often has a suture-like transverse line subdistally, and we consider this was probably interpreted as a true segmental boundary in these descriptions.
