Metallyticus is a genus of praying mantis. It is the only genus in the monotypic family Metallyticidae. They are mostly found in South-East Asia. The species of the genus are dark, somewhat flattened and cockroach-like, and often with a cuticle that is reflective and metallic in appearance.
The phylogenetic position of Metallyticidae relative to other mantis families has been studied using both morphological and molecular characters, but consensus on its placement has not been achieved. Along with the genera Chaeteessa and Mantoida, Metallyticus is considered a member of the basal Mantodea, Metallyticidae species have several autapomorphic traits, including their metallic coloration and the enlarged spine on their front legs. They also have many plesiomorphic traits, including a relatively short pronotum and full wings in both sexes.
