New insects (Insecta: Trichoptera, Eoblattida) from the Lower Permian of Russia

Shedding light on the enigmatic extinct insect order Glosselytrodea: new diversity and key morphological insights into non‐tegmenized Permian forms

“…Although Novokshonov (1998) recognized the composite eyes, the mandibles and the possible laciniae in his drawings of the holotype of S. latipennatum , these are photographically figured herein for the first time (Fig. 5).…”

“…2007). In contrast, the two species classified within the genus Glossopterum , G. sharovi Novokshonov, 1998 and G. martynovae Sharov, 1966, lack any development whatsoever of an ambient vein in the forewing (nor anteriorly or posteriorly, given that RA ends in the wing margin at a point similar to Permoberothidae and CuA post is fully straight as well), although an ambient vein is present in the Glosselytridae, Polycytellidae and Jurinidae. Therefore, there is no strong argument to maintain the genus Glossopterum in the Glosselytridae at present; it was transferred therein by Rasnitsyn & Aristov (2013).…”

“…An additional, undescribed, complete jurinid was figured by Rasnitsyn (2002). Moreover, Glossopterum martynovae and G. sharovi were described based on complete specimens (Sharov 1966; Novokshonov 1998; Rasnitsyn 2002; Zhuzhgova et al . 2015).…”

“…Most of the glosselytrodean diversity is known from isolated wings, particularly forewings due to their greater degree of sclerotization. Only a few body fossils have been described and/or figured (Martynov 1938; Martynova 1961; Sharov 1966; Novokshonov 1998; Rasnitsyn 2002). Because of these, it is known that glosselytrodeans were mandibulate, hypognathous to opisthognathous, had long wings in proportion to the body, and possessed cursorial legs, among other features.…”

Two new species of Itaphlebia (Insecta, Mecoptera, Nannochoristidae) from the late Middle Jurassic of China

“…So far, six genera: Dahurochorista Sukatsheva, 1985, Dahurolarva Sukatsheva, 1985, Itaphlebia Sukatsheva, 1985, Namdyrus Sukatsheva, 1993, Tarantogus Sukatsheva, 1985, and Undisca Sukatsheva, 1990, and one subgenus: Eunannochorista Novokshonov, 1997, from the Middle Jurassic and the Lower Cretaceous have been described ( Sukatsheva 1985 ; Sukatsheva 1990 ; Novokshonov 1997a , b ; Liu et al 2010 ; Cao et al 2015 ). However, the diagnoses of Dahurolarva and Tarantogus ( Sukatsheva 1985 ) are based only on larvae, as revised by Novokshonov (1997b) , and the diagnoses of Undisca and Itaphlebia ( Sukatsheva 1985 ; Sukatsheva 1990 ) need revision after new and more well-preserved fossils have become available. In this paper, we describe two new species of Itaphlebia : I.…”
