Genera edit

Prochresmoda from the Triassic of Kyrgyzstan is not currently considered part of the group and is considered to be more closely related to Triassophasma and Palaeochresmoda.[7]

Their affinities within the Polyneoptera have long been considered uncertain.[8] Some authors have suggested that they represent a derived group of cockroaches.[9]

Description edit

Chresmodidae are large enigmatic insects with very long specialized legs, probably adapted for skating on the water surface, similar to extant water skaters. They can reach a size of about 17 centimetres (6.7 in).[10][11] and even 19 centimetres (7.5 in).[12]

These Polyneoptera of uncertain position have been considered aquatic, living on the water surface, probably predaceous on nektonic small animals.[13][14]

They lived during the Cretaceous of Brazil, China, Lebanon, Spain, United Kingdom, as well as in the Jurassic of Germany and China, from ~166.0 to 94.3 Ma.[1]
