Extinct family of insects

Chresmodidae is an extinct family of Mesozoic insects within the superorder Polyneoptera.^[2]^[3]^[4]

Chresmoda Late Jurassic-Cenomanian, Worldwide
Jurachresmoda Zhang, Ren & Shih, 2008 Middle Jurassic, Jiulongshan Formation^[5]
Sinochresmoda Zhang, Ren & Pang, 2008 Early Cretaceous, Yixian Formation^[6]

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

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]
