“…A cladistic analysis based on 14 characters recovered Enicocephalinus as the sister-group to Enicocephalinae (Enicocephalidae) (Azar et al 1999). Recently, Luo & Xie (2022) suggested that Enicocephalinus should be moved to Aenictopecheidae based on the following characters: (1) compact pronotum; (2) forewing with short costal fracture; (3) ventral margin of mid and hind tibia with pairs of spines; and (4) pygophore and phallus well developed, mobile. We note that pairs of spines in the mid and hind tibia are common in Enicocephalidae (Fig.…”

“…Enicocephalomorphans are also highly unusual in the fossil record. In terms of past enicocephalomorphan diversity, 15 fossil species in nine genera have been described (for a recent review, refer to Luo et al (2021) and Luo & Xie (2022)), the oldest one being Enicocephalinus acragrimaldii Azar et al, 1999 from Lower Cretaceous Lebanese amber (Azar et al 1999). Other fossil enicocephalomorphans have been described from mid-Cretaceous Burmese and Miocene Dominican ambers, as well as from the lower Eocene London Clay Formation at Paddy's Point, Isle of Sheppey (Luo et al 2021).…”

Enicocephalomorpha, also known as unique‐headed bugs, are a seldom‐collected infraorder of heteropteran insects whose evolutionary relationships have puzzled entomologists for more than a century. Unique‐headed bugs are exceptionally rare in the fossil record, which hinders our understanding of the morphological transformations of the lineage across time and also affects the calibration of molecular clock estimates used to date the origins of the infraorder. Here, we report the discovery of Enicocephalinus ibericus sp. nov. from Iberian amber in the Ariño deposit in Spain, early Albian (Early Cretaceous) in age. The new species represents the second oldest fossil enicocephalomorphan to date, and the second record of this infraorder from European deposits. Remarkably, the closest relative of E. ibericus is the congeneric E. acragrimaldii Azar from Lebanese amber that is c. 20 myr older (Barremian), indicating a long‐term persistence of the Enicocephalinus lineage across geological time. A review of the existing literature enabled us to record a total of 20 congeneric insect species that have been found in both Lebanese and Iberian ambers, suggesting the existence of previously underappreciated entomofaunal connections between southern Laurasia (the European archipelago) and northern Gondwana during the Cretaceous. We show that the palaeoentomological record holds remarkable potential for elucidating the faunistic exchanges and palaeobiogeographical patterns in the peri‐Tethyan region during the Cretaceous.
