A new genus and first Cenozoic fossil record of moth lacewings (Neuroptera: Ithonidae) from the Early Eocene of North America

چکیده
A new genus and species Allorapisma chuorum gen. sp. nov. is described from the Early Eocene locality at Republic, Washington, U.S.A. The forewing venation of Allorapisma is most similar to that of the genus Principiala Makarkin & Menon from the Early Cretaceous of Brazil and Britain. A new, informal suprageneric taxon consisting of these genera is proposed, the Principiala group. The habitats of extant and fossil Ithonidae are briefly discussed.

New fossil species of Nymphidae (Neuroptera) from the Eocene of North America and Europe
Two new fossil species of Nymphidae (Neuroptera) are described: Nymphes georgei sp. nov. from the Early Eocene locality at Republic, Washington, U.S.A., and Pronymphes hoffeinsorum sp. nov. from Late Eocene Baltic amber. The assignment of the new Republic species to Nymphes Leach maintains some doubt. This is the first fossil record of the genus (or one very closely related), today restricted t...
متن کاملFirst record of the family Ithonidae (Neuroptera) from Baltic amber.
Elektrithone expectata gen. et sp. nov. (Neuroptera: Ithonidae) is described from Eocene Baltic amber and represents the first record of this family from Baltic amber. The forewing venation of the new genus is characterized by a small number of crossveins as found in some 'polystoechotid'-like genera, and by the absence of the distal nygma and the strong reduction of the anal area which are cha...
متن کاملAponogeton pollen from the Cretaceous and Paleogene of North America and West Greenland: Implications for the origin and palaeobiogeography of the genus☆
The fossil record of Aponogeton (Aponogetonaceae) is scarce and the few reported macrofossil findings are in need of taxonomic revision. Aponogeton pollen is highly diagnostic and when studied with light microscopy (LM) and scanning electron microscopy (SEM) it cannot be confused with any other pollen types. The fossil Aponogeton pollen described here represent the first reliable Cretaceous and...
متن کاملAn unusual new fossil genus probably belonging to the Psychopsidae (Neuroptera) from the Eocene Okanagan Highlands, western North America.
The new genus and species Ainigmapsychops inexspectatus gen. et sp. nov. is described from the early Eocene Okanagan Highlands locality at Republic, Washington, U.S.A. We preliminarily assign it to the Psychopsidae; however, its venation is unusual within this family, particularly by its pectinate branches of AA1 originating at a steep angle, a character state more suggestive of the Osmylidae.
متن کاملThe evolutionary convergence of mid-Mesozoic lacewings and Cenozoic butterflies
Mid-Mesozoic kalligrammatid lacewings (Neuroptera) entered the fossil record 165 million years ago (Ma) and disappeared 45 Ma later. Extant papilionoid butterflies (Lepidoptera) probably originated 80-70 Ma, long after kalligrammatids became extinct. Although poor preservation of kalligrammatid fossils previously prevented their detailed morphological and ecological characterization, we examine...
