Here's a take:
This species was the most common Zealleyella in the Table mountains and in Montagu. Similar to custodiens but smaller (similar to steingroeveri), legs shorter, less constricted mesosoma, all especially in the largest workers. Because of the silky silver pubescens this species was originally considered a subtaxon of custodiens (see Arnold, 1922). Pubescens are distinctly less than custodiens, however hard to separate in most pictures. Majority of custodiens, rufescens, and steingroeveri observations seem to be this species especially in the western cape area. Since Anoplolepis is not the best devised taxon, there still are taxa like Anoplolepis steingroeveri parsonsi which seems inseparable from fallax, but since fallax stands valid and was described before that subspecies I believe its enough to label this fallax for now
