Taxa named by Leonard Gyllenhaal

Histeridae is a family of beetles commonly known as clown beetles or hister beetles. There are more than 410 genera and 4,800 described species in Histeridae worldwide, with more than 500 species in North America. They can be identified by their shortened elytra, which leave two tergites exposed, and also by their elbowed antennae with clubbed ends. These predatory feeders are most active at night and will fake death if threatened. Hister beetles occupy almost any kind of niche throughout the world. They have also been useful for estimation of time of death during forensic investigations. Also

Histeroidea is a superfamily of beetles in the infraorder Staphyliniformia.

The Cassidinae (tortoise and leaf-mining beetles) are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra.

The Cryptocephalinae are a subfamily of the leaf beetles (Chrysomelidae), and belong to the group of case-bearing leaf beetles called the Camptosomata. The cases are made from the feces of larvae, passed from one instar to the next, and ultimately serves as a pupation chamber.

The Cassidini comprises approximately 40 genera worldwide, and is one of the largest tribes in the subfamily, containing most of the genera and species known collectively as "tortoise beetles". The subfamily names Cassidinae and Hispinae were both founded by Gyllenhal in the same 1813 book, but following the Principle of the First Reviser, Chen in this case, priority is given to the name Cassidinae.
