Abstract
A new genus and species, Undulopsychopsis alexi gen. et sp. n., is described from the Early CretaceousYixian Formation of western Liaoning Province, China. This genus is probably most closely related to the Asian Cretaceous genus Kagapsychops Fujiyama, 1978. The family affinity of Undulopsychopsis gen. n. is discussed. The genus is preliminarily assigned to Psychopsidae, although it shares some character states with Osmylopsychopidae (e.g., crossveins are very scarce; Rs1 and 1A are multi-branched).
Highlights
The extant Psychopsidae is a small family, currently restricted to disjunct regions in southern Africa, southeastern Asia and Australia (New 1988; Oswald 1993a; Wang and Bao 2006)
While many fossil psychopsids were recorded from the Mesozoic, few representatives have been described from the Tertiary
We describe a new genus and species of Psychopsidae from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, China
Summary
The extant Psychopsidae is a small family (five genera and 27 described species), currently restricted to disjunct regions in southern Africa, southeastern Asia and Australia (New 1988; Oswald 1993a; Wang and Bao 2006). 1953, Pulchroptilonia Martins-Neto, 1997, and Kagapsychops Fujiyama, 1978) may belong to another psychopsoid family, Osmylopsychopidae. The position of these and some other fossil genera from the Mesozoic is questionable, due to certain differences in details of the wing venation between fossil and extant psychopsids (e.g., the pattern of Rs branches, the configuration of M and Cu in the forewing, the structure of vena triplica), their general venational pattern is similar to that of extant representatives. We describe a new genus and species of Psychopsidae from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, China
