Clatrotitan is an extinct genus of titanopteraninsect, known from the Triassic of Australia.[1] It is originally described from a species, C. andersoni, then later study considered that Mesotitan scullyi as species of Clatrotitan too. But another study synonymized Mesotitan and Clatrotitan. A study in 2021 proposed to keep the two genera Clatrotitan and Mesotitan separated.[2]C. andersoni had a large forewing, which was 13.8 centimetres (5.4 in) long.[3]
