This monograph presents a comprehensive revision of the Indo-Pacific dottyback fish subfamily Pseudochrominae, addressing the taxonomic complexities within the family Pseudochromidae. The author, Anthony C. Gill, a recognized ichthyologist, draws upon extensive morphological and taxonomic research to clarify species relationships and establish a robust classification for this group of marine fishes. The work aims to provide a definitive systematic account for researchers and ichthyologists working with Indo-Pacific reef fish fauna.

This specialized monograph is regarded as a foundational contribution to the taxonomy of Indo-Pacific reef fishes. Its detailed systematic treatment and reliance on morphological evidence establish it as a key reference for ichthyologists and marine biologists. The work is expected to be utilized by researchers for species identification and for understanding the evolutionary history of the Pseudochrominae subfamily.
