The species was first formally described by the botanist Bruce Maslin in 1999 as part of the work "The taxonomy of fifty-five species of Acacia, primarily Western Australian, in section Phyllodineae" as published in the journal "Nuytsia". It was reclassified as "Racosperma pusillum" by Leslie Pedley in 2003 and transferred back to genus "Acacia" in 2014. It is closely related to "Acacia rhamphophylla" and resembles "Acacia lachnophylla". Distribution. It is native to an area along the south coast in the Goldfields-Esperance region of Western Australia from around Esperance  in the west to around Israelite Bay in the east where it is found around the margins of salt lakes and on sandplains growing in sandy-clay soils often around limestone. The bulk of the population is found in the Ravensthorpe Range situated on the lower slopes often around watercourses as a part of dense mallee shrub and woodland communities.
