Mantidae is one of the largest families in the order of praying mantises, based on the type species Mantis religiosa; however, most genera are tropical or subtropical. Historically, this was the only family in the order, and many references still use the term "mantid" to refer to any mantis. Technically, however, "mantid" refers only to members of the family Mantidae, and not the 14 remaining families of mantises. Some of the most recent classifications have promoted a number of the mantid subfamilies to the rank of family, e.g. Iridopterygidae, Sibyllidae, Tarachodidae, Thespidae, and Toxoderidae, while other classifications have reduced the number of subfamilies without elevating to higher rank.
Eremiaphilidae is a small Old World family of praying mantids, based on the type genus Eremiaphila. As part of a major revision of mantid taxonomy, this family now contains the subfamily Tarachodinae, which includes tribes and genera previously placed in the now obsolete Tarachodidae.
Liturgusidae is a family of praying mantids in the new (2019) Neotropical superfamily Acanthopoidea. A substantial number of genera, previously placed here, have recently been moved to the new or revived other families:
Iridopterygidae was a family of praying mantids in the order Mantodea whose members, having formerly been moved here as a subfamily within Mantidae, have now been transferred elsewhere as part of the recent (2019) major revision of mantid taxonomy.
Miomantidae is a family of praying mantises in the order Mantodea.
Haania is the type genus of Asian praying mantids in the new (2019) family Haaniidae. They are recorded from: southern China (Hainan), Indo-China and the Philippines.
Deiphobe is an Asian genus of praying mantids: in the family Rivetinidae.
Leptomantella is a genus of praying mantids and typical of the new (2019) family Leptomantellidae. Species have been recorded from Asia.
Thespinae is a subfamily of mantids in the family Thespidae. There are 16 genera and at least 40 described species: found in Australasia, Central and South America.
The Haaniidae are a new (2019) family of praying mantids, based on the type genus Haania. The first use of "Haaniidae" was by Giglio-Tos and it was revived as part of a major revision of mantid taxonomy; genera in the subfamily Haaniinae havie been moved here from the family Thespidae.
The Hierodulinae are a subfamily of praying mantids, originally used by Brunner von Wattenwyl. It was restored as part of a major revision of mantid taxonomy, and now contains genera previously placed elsewhere in the family Mantidae.
The Nanomantidae are a new (2019) family of praying mantises, based on the type genus Nanomantis. As part of a major revision of mantid taxonomy, genera and tribes have been moved here, substantially replacing the old family Iridopterygidae.
The Gonypetidae are a new (2019) family of praying mantids, based on the type genus Gonypeta. The first use of "Gonypetidae" was by Westwood and it has been revived as part of a major revision of mantid taxonomy; the subfamily Iridopteryginae having been moved here from the obsolete family Iridopterygidae. The Gonypetinae include Asian genera transferred from the obsolete taxa Amelinae and Liturgusidae.
The Deroplatyidae are a new (2019) family of praying mantises, based on the type genus Deroplatys. As part of a major revision of mantis taxonomy, the subfamily Deroplatyinae has been moved here from the previously-structured family Mantidae.
Hoplocoryphidae is a newly erected (2019) family of praying mantids, based on the type genus Hoplocorypha. As part of a major revision of mantid taxonomy, genera have been moved here from the subfamily Hoplocoryphinae of the previously polyphyletic family Thespidae. The family Hoplocoryphidae is the only member of superfamily Hoplocoryphoidea. Species in this family have been recorded from tropical Africa.
The Majangidae are a revived (2019) family of praying mantids from Madagascar.
The Rivetinidae are a family of praying mantids, based on the type genus Rivetina. As part of a major revision of mantid taxonomy, this family contains many genera moved from Miomantinae: tribe Rivetinini; some genera previously placed there have now been moved to the new families Deroplatyidae and Chroicopteridae. The new placement of this taxon is in the superfamily Eremiaphiloidea and infraorder Schizomantodea.
The Chroicopteridae are a new (2019) family of praying mantids, based on the type genus Chroicoptera. The name is derived from first use, for subfamily Chroicopterinae, by Giglio-Tos and it has been revived as part of a major revision of mantid taxonomy. Some genera have also been moved here from the tribe Rivetinini, with others placed elsewhere including the subfamily Miomantinae.
The Tenoderinae are a subfamily of praying mantids, originally used by Brunner von Wattenwyl. It was restored as part of a major revision of mantid taxonomy, and contains many genera previously placed in the subfamily Mantinae.
