Syntarsus (beetle)
''Syntarsus'' is a generic name that has been used for the following taxa: *''Syntarsus'' a junior synonym of the Colydiinae beetle genus '' Cerchanotus'' Erichson, 1845. *''Syntarsus kayentakatae'' is the former name of a theropod dinosaur later classified as ''Megapnosaurus'', but is now not definitively assigned to any specific genus. *'' Syntarsus rhodesiensis'' is the former name of a theropod dinosaur later classified as ''Megapnosaurus ''Megapnosaurus'' (meaning "big dead lizard", from Greek μεγα = "big", 'απνοος = "not breathing", "dead", σαυρος = "lizard") is an extinct genus of coelophysid theropod dinosaur that lived approximately 188 million years ago duri ...

Colydiinae
Colydiinae is a subfamily of beetles, commonly known as cylindrical bark beetles. They have been treated historically as a family Colydiidae, but have been moved into the Zopheridae, where they constitute the bulk of the diversity of the newly expanded family, with about 140 genera worldwide. They are diverse for example in the Australian region, from where about 35 genera are known; in Europe, though, only 20 genera are found and many of these only with few species.

Little is known about the biology of these beetles. Most feed on fungi, others are carnivores and eat small arthropods such as bark beetles.  (1987): ''Beetles of Australia''.

Coelophysis? Kayentakatae
''Coelophysis''? ''kayentakatae'' is an extinct species of neotheropod dinosaur that lived approximately 200 - 196 million years ago during the early part of the Jurassic Period in what is now the southwestern United States. While originally assigned to the genus '' Syntarsus'' as ''Syntarsus kayentakatae'', that genus name was found to be preoccupied by a Colydiine beetle, so it was moved to the genus ''Megapnosaurus'' as ''Megapnosaurus kayentakatae''. Later it was moved again to ''Coelophysis'', however the species still possesses no definite genus assignment. Discovery The holotype of ''C.''? ''kayentakatae'' (MNA V2623) was recovered in the Silty Facies Member of the Kayenta Formation in Arizona. This material was collected in 1977 from carbonaceous sandstone deposited during the Sinemurian and Pliensbachian stages of the Jurassic period.Padian, K (1997) Glen Canyon Group In: Encyclopedia of Dinosaurs, edited by Currie, P.

Megapnosaurus
''Megapnosaurus'' (meaning "big dead lizard", from Greek μεγα = "big", 'απνοος = "not breathing", "dead", σαυρος = "lizard") is an extinct genus of coelophysid theropod dinosaur that lived approximately 188 million years ago during the early part of the Jurassic Period in what is now Africa. The species was a small to medium-sized, lightly built, ground-dwelling, bipedal carnivore, that could grow up to long and weigh up to . It was originally given the genus name ''Syntarsus'', but that name was later determined to be preoccupied by a beetle. The species was subsequently given a new genus name, ''Megapnosaurus,'' by Ivie, Ślipiński & Węgrzynowicz in 2001. Some studies have classified it as a species within the genus ''Coelophysis,'' but this interpretation has been challenged by more subsequent studies and the genus is now considered valid. Discovery and history The first fossils of ''Megapnosaurus'' were found in 1963 by a group of students from Northlea S ...
