Thank you for agreeing to review this paper in New Australian Taxa. As you know, peer review is a critical step in ensuring high quality, adequate care and scientific rigour in taxonomy.
Reviewing for New Australian Taxa may be slightly different to reviewing for other more conventional journals. New Australian Taxa specialises in papers describing new taxa in as straightforward a manner as possible. It forms part of a strategy to accelerate the documentation of Australia's species. While as a reviewer you are asked to draw attention to inaccuracies, ambiguities and errors in this paper, please ensure that your review focuses on ensuring adequacy rather than demanding unreasonable levels of detail.
New Australian Taxa is also a lightly styled journal. That is, there is no highly prescriptive journal style to which authors must conform. Rather, authors are expected to be consistent within a paper, reasonable, and moderately conventional in their styling and formatting. Within these bounds, New Australian Taxa allows considerable latitude. Please look for and point out to the author anything that creates ambiguity or reduces clarity, but do not ask for formatting changes that achieve nothing more than consistency for its own sake.

The new species Hibbertia arenaria K.R.Thiele sp. nov., comprising specimens formerly ascribed to H. aff. axillibarba J.R.Wheeler, is described. Hibbertia aranaria is restricted to sandplain habitats in the general vicinity of South Ironcap, on which H. axillibarba is endemic; the two species are clearly morphologically distinct.
Hibbertia axillibarba J.R.Wheeler was described based on four specimens, all from the summit and upper slopes of South Ironcap, a banded ironstone hill c. 40 km north of Lake King (Wheeler, 2000). Since publication, three further specimens have been collected, all from South Ironcap.
Four Hibbertia specimens collected from sandplains in the vicinity of South Ironcap were placed at the Western Australian Herbarium in H. aff. axillibarba. These constitute a species distinct from H. axillibarba, described here as H. arenaria.
