Families

Coleorrhyncha, also known as moss bugs or beetle bugs, are an order of true bugs, comprising one extant family, the Peloridiidae, with other Coleorrhyncha being known only from the fossil record, notably the early Progonocimicidae, and the later Karabasiidae and Hoploridiidae.[1] The Coleorrhyncha provide an insight into the evolution of Gondwana insects because of their long evolutionary history, distinct morphological features and the limited distribution of the extant species.[2] On the basis of morphology and molecular studies, Brozç concluded that the Coleorrhyncha belong as a sister group co-equal with the Heteroptera.[3]

Progonocimicidae were formerly considered as early Heteroptera or survivors from a stem group of Heteropteroides.[4] However based on morphology, Popov called them an ancestral sub-group of the Coleorrhyncha,[5] and was followed by subsequent authors.[6]

In 2013 a new species of Progonocimicidae, the fossil species, Cicadocoris assimilis, was discovered in rocks of the Middle Jurassic in China.[7]
