Wood and Bright (1992) considered the species as being described by Stebbing in 1909 (Stebbing, 1909: 20) and rather than in 1907 despite listing this publication under the taxonomy section for the species. This error undoubtedly occurred because Stebbing classified Phloeosinus minor as a new species in both publications. However in 1909 he states “this amplifies the description given of this insect in ” at the end of the species description. This error has been unknowingly perpetuated throughout the literature published since 1992.
