Acanthops is a genus of mantises in the family Acanthopidae, containing 20 species that can be found in Central and South America.
Most species in Acanthops are colloquially referred to as the dead leaf mantis, a common name also used for species in several other mantid genera. The genus name translates from the Greek nouns ἄκανθα and ὅψ as "thorn eye", referring to the presence in all Acanthops species of a shorter or longer conical tubercle on top of each eye. Note that such ocular tubercles also occur in various other mantid genera.
Acanthops species have an unusual degree of sexual dimorphism compared to other mantids. The flightless female resembles a curled dead leaf folded back on itself, and weighs twice as much as the males do. It has reduced wings that can be raised to reveal bright warning colors on the abdomen. The male has long functional wings that resemble a flat or rolled-up dead leaf at rest. When perched, males often assume a posture where the head, grasping legs and prothorax add to the camouflage effect by recreating the appearance of a dead leaf's shriveled petiole and stipules.
The following species are currently considered valid: [1] [2] [3] [4]
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 numerous 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 them 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.
Creobroter is a genus of flower mantises in the tribe Hymenopodini; species are concentrated in Asia. The name comes from the Greek kreo-, meaning "flesh") and broter" meaning "eating", therefore, "flesh-eating", an apt name for a predatory insect. Both sexes have long wings and are capable fliers. Full-grown males are about 3 to 4 cm in length; females are about 4 to 5 cm.
Liturgusidae is a family of praying mantises 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:
Ameles spallanzania, common name European dwarf mantis, is a species of praying mantis.
Acanthops falcataria, common name South American dead leaf mantis, is a species of mantis in the family Acanthopidae. It is not to be confused with Acanthops falcata, a different species in the same genus that is often referred to with the same common name.
Rhombodera is a genus of praying mantises native to Asia and possessing common names such as shield mantis, hood mantis, and leaf mantis because of their extended, leaf-like thoraxes.
Thespidae is a family of insects in the order Mantodea. Following a major revision of this order in 2019, the old-world subfamilies Haaniinae and Hoplocoryphinae, previously placed here, have been upgraded to family level. Thespidae are mostly Neotropical and few species have reached the Nearctic realm.
Acanthopidae is a family of South American mantises consisting of 16 genera in the order Mantodea. The group was first formally split off as a separate family by the German entomologist Reinhard Ehrmann in 2002. In 2016, five genera were moved from Acanthopidae to the newly created family Acontistidae, but this has not been accepted in most recent classifications.
Acanthopini is a tribe of mantises in the family Acanthopidae. Ii is the only tribe in the subfamily Acanthopinae and contains eight genera and 37 species.
Miomantidae is a family of praying mantises in the order Mantodea.
Acontistini is a tribe of neotropical mantises in the superfamily Acanthopoidea, and family Acanthopidae. There are 7 genera and more than 30 described species in Acontistini. In 2016, several genera were moved from Acanthopidae to a newly created family Acontistidae, but this has not been accepted in most recent classifications.
Coptopterygidae is a family of mantises in the order Mantodea. There are at least 2 genera and more than 20 described species in Coptopterygidae.
Photinaidae is a family of mantises in the order Neotropical Mantodea, in the superfamily Acanthopoidea. There are about 11 genera and more than 40 described species in Photinaidae.
Thespinae is a subfamily of mantises in the family Thespidae. There are 16 genera and at least 40 described species: found in most continents.
Pseudovates is a genus of praying mantis in the family Mantidae. There are more than 20 described species in the genus Pseudovates, and are found in North, Central, and South America.
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 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.
