TL;DR: The largest suborder of bark lice (Insecta: Psocodea: ‘Psocoptera’) is Psocomorpha, which includes over 3600 described species and the phylogeny of this major group with family-level taxon sampling using multiple gene markers is estimated.
TL;DR: The ecology of 62 species of Psocoptera obtained in a survey carried out in the dry season in East Africa is discussed in this paper, where 28 new species are described: Thylacella angustipennis; Lepinolus fuscus; Trogium apterum; Hemiseopsis obscurus; Liposcclis pleswpuber; Caecilius aequalis, frater, proxmus and uirgalus; Paracaecileus copiosus and lucidus; Harpezoneura indotata; Lcc
Abstract: The ecology of 62 species of Psocoptera obtained in a survey carried out in the dry season in East Africa is discussed. Twenty-eight new species are here described: Thylacella angustipennis; Lepinolus fuscus; Trogium apterum; Hemiseopsis obscurus; Liposcclis pleswpuber; Caecilius aequalis, frater, proxmus and uirgalus; Paracaecilius copiosus and lucidus; Harpezoneura indotata; Lcchesilla acutiloba, cornistema, keniensis and rectigladia; Heterocaecilius aequabilis; Pseudoscottiella maculata; Elipsocus ignobilis; Lesneia niger and pulchra; Haplophallus afruanus; Mesopsocus acutilobus, alatus, difiilis, nitidifrans and propinquus. Redescriptions are given of Caecilius inquinatus Enderlein, Paracaecilius pallidus (Pearman), Harpezoneura pallens Pearman, Pseudocaecilius morstatti Enderlein and Mesopsocus montinus Enderlein. Keys are given to the African species of Paracaecilius Badonnel and to the East African species of Mesopsocidae. A checklist of the Psocoptera known from East Africa is provided.
TL;DR: Twenty seven new species of Psocomorpha (Psocoptera) from the Malayan Peninsula and Singapore are described and figured, belonging to Epipsocidae, Caeciliidae, Amphipsoc Families, Pseudocaeci- liidae, Myopsocidae and Psocidae.
Abstract: Recent collections of Psocomorpha (Psocoptera) from the Malayan Peninsula and Singapore are enumerated. Twenty seven new species are described and figured, belonging to Epipsocidae (10), Caeciliidae (2), Amphipsocidae (1), Pseudocaeci- liidae (3), Philotarsidae (1), Peripsocidae (4), Myopsocidae (2) and Psocidae (4). Illustrated redescriptions of the types of Epipsocus prominens Banks, E. Hyalinus Banks, E. fumlpennis Banks and Allopsocus marginalia Banks are given. E. Fumlpennls and E. Hyalinus are transferred to Epipsocopsis Badonnel, and Allopsocus Banks placed in the Pseudocaeciliidae. Records are given of 9 other earlier described species, and of unidentified species of Mesopsocidae (1), Caeciliidae (5) and Archipsocidae (1).
TL;DR: In this paper, the fossil psocodeans from Late Cretaceous (Cenomanian to Santonian) amber of Vendee, in northwestern France, are studied.
Abstract: The fossil psocodeans from Late Cretaceous (Cenomanian to Santonian) amber of Vendee, in northwestern France, are studied. Two new genera and three new species are described and illustrated, as Proprionoglaris axioperierga n. sp. (Archaeatropidae), Scocompus atelisus n. gen. and sp. (uncertain family within the Amphientometae), and Mesopsocoides dupei n. gen. and sp. (earliest fossil record of the Mesopsocidae). The new fossils are distinguished from their congeners, and their respective systematic placement is discussed. Other fragmentary fossil psocodeans from the same outcrop are illustrated and discussed.
