Diagnosis: The family Adrianichthyidae View in CoL is diagnosed as monophyletic by 17 unambiguous synapomorphic characters: vomer absent, articular surface of the fourth epibranchial bone greatly expanded; ceratobranchial epiphysis represented by complex, branched cartilages; ceratobranchial 4 edentulous; palatine bone articulates with the maxilla (or premaxilla) via a dense ligament; rostral cartilage absent; Meckel’s cartilage one-half length of the dentary and articular bone orientated dorsally relative to the body axis; cartilaginous symphysis between the left and right dentary; metapterygoid absent; pterygoquadrate cartilage enlarged dorsally; no mandibulo-lacrimal ligament; dermosphenotic lateral or posterior to sphenotic; supracleithrum absent; posttemporal bone simple, with no ventral arm; anterior ramus of coracoid relatively broad, particularly at point of articulation with the cleithrum, and without cartilage; ventral accessory bone in the caudal skeleton; and ventral branch of the posterior lateral line nerve in adults without pored lateral line scales. An additional nine synapomorphies are reversed at internal nodes on the consensus cladogram ( Figs 30 View Figure 30 , 31 View Figure 31 and Discussion): scales in a lateral series number 70 or more; ventral hypohyal has an elongate blade-like ramus along ventral face of anterior ceratohyal; five branchiostegal rays; posteriormost branchiostegal ray articulates with truncated posterior ceratohyal; dorsal fin rays number 11–13; hooked procurrent caudal-fin rays; 44 or fewer diploid chromosomes; metacentric chromosomes (biarmed); and extremely large metacentric (fused) chromosomes present.

A fossil genus and species, † Lithopoecilus brouweri de Beaufort, 1934 , from the Miocene of Sulawesi, is included tentatively here.

Remarks: Authorship of the family-group name based on the genus Oryzias View in CoL has been attributed to Rosen (1964: 225) who used the phrase ‘ Oryziatidae , new family’ apparently unaware that Myers (1938: 137) authored the tribe Oryziatini . Spelling of the family-group name was modified subsequently to Oryziidae by Steyskal (1980).
