Evidence Supporting a Sister-Group Relationship between Clupeoidea and Engrauloidea (Clupeomorpha)
TLDR
Evidence counter to this proposed relationship is the common presence of the gongyloid cartilage in the branchial arches of Pristigasteroidea and Engrauloidea, a structure apparently previously unrecorded in the literature and whose homologies are discussed.

Chirocentrids as engrauloids: evidence from suspensorium, branchial arches, and infraorbital bones (Clupeomorpha, Teleostei)
TLDR
Seven previously unreported derived character states from the suspensorium, branchial arches, and infraorbitals strongly indicate a hitherto unsuspected sister group relationship between the Chirocentridae and Engrauloidea, which comprises approximately 140 species of the commercially important fishes known as anchovies.

Homology between the recessus lateralis and cephalic sensory canals, with the proposition of additional synapomorphies for the Clupeiformes and the Clupeoidei
TLDR
Hypothesized synapomorphies in the recessus lateralis for the Clupeiformes are the presence of a dilated internal temporal sensory canal in the pterotic, a postorbital branch of the supraorbital sensory canal located in a bony groove in the lateral wing of the frontal, and the terminal portions of preopercular and infraorbitals sensory canals closely positioned.

A new remarkable and Critically Endangered species of Astyanax Baird & Girard (Characiformes: Characidae) from Chapada Diamantina, Bahia, Brazil, with a discussion on durophagy in the Characiformes.
TLDR
Analysis of gut contents of adults revealed the almost exclusive presence of crushed shells of tiny gastropods of the family Hydrobiidae, likely adaptations to durophagy, a feeding strategy unusual among characids.
