Orophus

Katydids in this genus have an elongated head with ovoid eyes. The ovipositor is medium-sized, slightly crenulated, curving upwards, and one fifth of the length of the posterior femur.^[2] They are found in the understory rather than in the canopy in contrast with other members of the subfamily Phaneropterinae.^[2][3]

The group was originally named in 1859 by Swiss entomologist Henri Louis Frédéric de Saussure as a subgenus of Phylloptera.^[4] It was erected as a separate genus in 1869 by British entomologist Francis Walker.^[5] It is in the tribe Amblycoryphini within the subfamily Phaneropterinae.^[1] The type species is Orophus mexicanus (originally Phylloptera mexicana).^[1] Other genera with species previously placed in Orophus include Eurycorypha and Microcentrum.^[2][6]

As of 2019^[update], the genus includes seven species split into three species groups:^[1][2]
