Trochoideus desjardinsi is a species of handsome fungus beetle in the family Endomychidae. [1] [2] [3] [4] [5] It is found in Africa, North America, and Southern Asia. [1]
The species is widely distributed in many Pacific and Indian islands and mainlands such as Andaman Islands, Borneo, Fiji, India, Java, Madagascar, Malay Peninsula, the Mascarene Islands, Myanmar, New Guinea, the Philippines, Samoa, Seychelles, Sri Lanka, Thailand. It is also introduced to Florida in the United States. [6]
Typical length is about 3.0 to 4.0mm. Body elongate and parallel-sided. Dorsum consists with short dense setae. Antennae with five segments, short, and swollen as an adaptation to life with ants and termites. [7] The last antennal segment is greatly swollen in males whereas female has a sausage-shaped last antennal segment. Pronotum with lateral sulci by very shallow depressions on the basal margin. Prosternum very narrow. Tarsi are 4 segmented. [6]
Adults are considered as a minor pest of stored grain products where it feeds on the hyphae and spores of a variety of molds. They commonly inhabited in the dead leaves, in dead wood, and under bark. They are known to live in the nests of the ants Paratrechina longicornis and Anoplolepis longipes and termite species such as Macrotermes gilvus and Eurytermes ceylonicus . Adults are often collected from many economically important plants such as banana, in rotten papaya, in dead rachis of Angiopteris and rotting coconut husks. Adults are easily attracted to many light traps such as ethanol/turpentine traps, mercury vapor lights, black lights, and fluorescent light traps. [6]
Endomychidae, or handsome fungus beetles, is a family of beetles with representatives found in all biogeographic realms. There are around 120 genera and 1300 species. The family was established based on the type genus Endomychus, a genus erected in 1795 by Panzer which was applied to a species that Linnaeus called Chrysomela coccinea. As the common name suggests, Endomychidae feed on fungi. Crowson, in his influential treatment of the beetles, placed the family within the Cucujoidea. They have a tarsal formal of 4-4-4 or 3-3-3 and the wings lack a closed radial cell. The second antennal segment has a sensory appendage that is as long as the third antennal segment. The family has also been grouped with the Coccinellidae in a group called the Trimera for having pseudotrimerous tarsi. A 2015 molecular phylogeny study found that the Cucujoidea were found to be non-monophyletic and the Endomychidae was refined with the removal of the Anamorphinae from within the family and elevated to the status of a full family, Anamorphidae. Mycetaeinae and Eupsilobiinae were also found not to belong within the clades of the core Endomychidae, and likewise reclassified into the families Mycetaeidae and Eupsilobiidae.
Epipocus gorhami is a species of handsome fungus beetle in the family Endomychidae. It is found in Central America and North America.
Coccinelloidea is a superfamily of beetles in the order Coleoptera, formerly included in the superfamily Cucujoidea. There are more than 10,000 species in Coccinelloidea, including more than 6000 in the lady beetle family Coccinellidae.
Holopsis is a genus of minute hooded beetles in the family Corylophidae. There are about 9 described species in Holopsis.
Anamorphidae is a family of beetles in the superfamily Coccinelloidea, formerly included within the family Endomychidae. They are found worldwide. Like enchomyids, they are fungivores, with adult and larval stages thought to exclusively consume fungal spores.
Mycetaeidae is a family of beetles in the superfamily Coccinelloidea, formerly included within the family Endomychidae. There are two genera currently included in the family, Agaricophilus and Mycetaea, which are morphologically divergent from each other, and it is unclear whether they are closely related. Mycetaea is found in North America, Europe and South Africa, while Agaricophilus is restricted to Europe. While the life history of Agaricophilus is obscure, Mycetaea is known to be mycophagous, feeding on molds.
Eupsilobiidae is a family of beetles in the superfamily Coccinelloidea, formerly included within the family Endomychidae. Most genera are restricted to the Neotropics, while the genus Eidoreus is found worldwide. They are fungivores, and have been observed living commensally in bee and ant nests.
Epipocus is a genus of handsome fungus beetles in the family Endomychidae. There are at least 20 described species in Epipocus.

Phymaphora is a genus of handsome fungus beetles in the family Endomychidae. There are at least two described species in Phymaphora.
Leiestinae is a subfamily of handsome fungus beetles in the family Endomychidae. There are at least three genera and about five described species in Leiestinae.
Rhanidea is a genus of handsome fungus beetles in the family Endomychidae. There is one described species in Rhanidea, R. unicolor.
Holoparamecus is a genus of handsome fungus beetles in the family Endomychidae. There are about 17 described species in Holoparamecus.
Merophysiinae is a subfamily of handsome fungus beetles in the family Endomychidae.

Hadromychus is a genus of handsome fungus beetles in the family Endomychidae. There is one described species in Hadromychus, H. chandleri.
