The Family

Two species of Jurodidae: Jurodes ignoramus and Jurodes minor are redescribed, new characters presented, and characters from original descriptions are phylogenetically reevaluated, justifying a placement of the family within the suborder Archostemata. The new species Jurodes shef sp. nov. from the Lower Cretaceous locality Khasurty (Berriasian-Barremian, Zakamenskiy district, Buryatia Republic, Russia) is described and 2 new specimens of J. ignoramus Ponomarenko, 1985 and 5 additional specimens of J. minor Ponomarenko, 1990 are recorded. Jurodids from Khasurty are morphologically closer to those from Daohugou locality (Middle–Upper Jurassic, Inner Mongolia, China).

A New Species

A new species of the family Prophalangopsidae, Ashanga borealis sp.n., is described from the Lower Cretaceous Yixian Fomation (Liaoning Province, P.R. China). The male forewing of the new species is similar to that of the Middle/Upper Jurassic species Ashanga clara Zherikhin 1985, but differs from it in possessing a forewing arched anterior margin, RS branching more basally, and MP + CuA1 with more branches. The fossil record of Chifengiinae is reviewed.

Shell structure has been studied in two species of the family Craniidae Menke, 1828, from the Upper Jurassic of East Ukraine and from the Lower Cretaceous of Crimea, South Ukraine. These species belong to the new genus Mesocrania—M. barskovi (Smirnova, 1972) and M. condylata new species. A layer of coarse regular rhomboidal crystallites was discovered between the primary layer of acicular crystallites and the secondary laminar layer. Branching punctae canals were observed in M. barskovi.

A nematocerous fly family known previously only from one species and specimen from the Upper Jurassic of Karatau, Kazakhstan, Archizelmiridae is expanded here to include additional records preserved as compression fossils and ones in amber. The compressions are from the Upper Jurassic of Shar-Teg, Mongolia and Lower Cretaceous of Baissa, Transbaikal, with a new species, Archizelmira baissa, from Baissa. Particularly significant are three finely preserved new species and genera in ambers from the Cretaceous Period: Zelmiarcha lebanensis (Lebanon: Lower Aptian), Archimelzira americana (New Jersey: Turonian), and Burmazelmira aristica (Burma [Myanmar]: mid-Cretaceous). The latter two species interestingly possess stylate antennae, those of Burmazelmira being the only aristate antennae in the order Diptera outside the suborder Brachycera. A cladogram is presented for the relationships among archizelmirid species, cladistic rank of which correlates with stratigraphic age. Transformation series of the antennal flagellum in Archizelmiridae corresponds with one recently hypothesized for the Brachycera, wherein the style and arista are derived from the apical flagellomere(s). The family appears to be a member of the extant group Sciaroidea, which includes fungus gnats and gall midges, though precise relationships remain unclear.

A New Species

A new genus with a new species of Chresmodidae (Insecta: Gryllones), Sinochresmoda magnicornia gen. et sp. nov., including specimens of male, female and nymph, is described and illustrated. These fossils were collected from the Upper Jurassic-Lower Cretaceous of Yixian Formation of Liutiaogou Village, Inner Mongolia (Nei Mongol Autonomous Region), China. Both male and female possess wings, and have sexual dimorphism in antenna. Antennae of male are highly specialized and horn-shaped, incurvated as horn with the scape strongly expanded, and the first segment of the flagella incurvated as a pair of brackets, while antennae of female are normally filiform. Wings of the new species are short, not exceeding the length of the abdomen. Fringe hairs along the wing margins, a unique feature for Chresmodidae, are dense, wavy and bundled together. Nymphs and adults probably lived in the same environment. In addition, one specimen demonstrates the extraordinary structure of tarsus with a high number of “tarsomeres”, which has been reported in other species of this family.

A New Species

Ptychopteridae is an ancient and rather diverse nematoceran family with three extant and 12 fossil genera subdivided into 80 extinct species belonging to five subfamilies (Eskov & Lukashevich, 2015; Lukashevich, 2019, 2020; Liu & Huang, 2020). Several undescribed ptychopterid larvae from the Upper Triassic of Germany represent the oldest record of the family (Barth et al., 2011). Crenoptychoptera Kalugina, 1985, an extinct genus belonging to the subfamily Eoptychopterinae Handlirsch, 1906, includes seven described species. All these species were recorded from the Lower Jurassic to the Lower Cretaceous of Eurasia: C. dobbertinensis Ansorge, 1998 from the Lower Jurassic of the Former Clay in Germany (Lukashevich et al., 1998), C. conspecta Lukashevich, 1995 from the Lower Jurassic of Ust-Baley in Russia (Lukashevich, 1995), the type species C. antica Kalugina, 1985 and C. defossa Kalugina, 1985 from the Middle Jurassic of the Kubekovo in Russia (Kalugina & Kovalev, 1985), C. bavarica Krzemiński & Ansorge, 1995 from the Upper Jurassic of Wegscheid in Germany (Krzemiński & Ansorge, 1995), C. liturata Lukashevich, 2011 from Upper Jurassic of Shar Teg in Mongolia, and C. gronskayae Kalugina, 1989 from the Upper Jurassic to Lower Cretaceous of Kempendyay in Russia (Kalugina, 1989; Lukashevich, 2011). Three species discovered from the Daohugou beds of China have been assigned to Crenoptychoptera (Hao et al., 2009), but a following study suggested that they should be placed in Axymyiidae (Zhang, 2010).

Abstract Although cockroaches were the dominant insects in various Paleozoic and Mesozoic insect assemblages, their general morphology was extremely conservative. One of the most common of them, the Jurassic-Cretaceous family Mesoblattinidae, is described here for the first time on the basis of completely preserved specimens. Ninety-two specimens of Perlucipecta aurea gen. et sp. n. reveal details of head, mandible, male tergal glands and terminal hook; cercal, leg and antennal sensilla. Its congener, P. vrsanskyi is described from the same sediments of the Yixian Formation (Upper Jurassic-Lower Cretaceous). The forewing venation variability of P. aurea, analysed for the first time in this family is nearly identical (CV = 6.23 %) with variability of two species of family Blattulidae that occur at the same locality (CV = 6.22 %; 5.72 %). The transitional nature of morphological characters represented by asymmetry between left and right wings (simple/branched forewing SC and hind wing M) in P. aurea documents the phylogenetic relation between the families Mesoblattinidae and Ectobiidae

A New Species

Recently, we (Akkari & Enghoff 2011) described a new species of the genus Rharodesmus Schubart, 1960, discussing the taxonomic state of the family Pyrgodesmidae and providing notes on the four genera occurring in the west Palaearctic area. However, we failed to present details on the holotype of the new species, which we now provide in this note in order to make the species name available. Thus, we describe here the new species Rharodesmus tabarkensis Akkari & Enghoff by reference to the full description given in Akkari & Enghoff (2011) with the following information on the type material: Holotype ♂, TUNISIA, NW, Jendouba Governorate, Tabarka, N36°57.8, E8°44.6, alt. < 40 m, coastal slope below the Genoese fort, under stones, 9.iii.2009, N. Akkari & H. Enghoff leg. (Natural History Museum of Denmark, Zoological Museum, University of Copenhagen, ‒ ZMUC); Paratypes: 12 ♂♂, 8 ♀♀, 14 juveniles, same locality and date as holotype, N. Akkari & H. Enghoff leg. (ZMUC).

Two new species, Itaphlebia exquisita sp. nov and Itaphlebia laeta sp. nov., were collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou, Inner Mongolia, China. A key to the species of the genus Itaphlebia is provided and diagnosis of the genus is revised. Itaphlebia exquisita sp. nov differs from other species in having an extra medial vein branch. Itaphlebia laeta sp. nov shows a transitional character to the extant genera by having a simple Sc. These new findings expand the distribution of Itaphlebia from middle-southern Russia to northeastern China.

A New Species

A new species of the family Grammolingiidae (Neuroptera) (Leptolingia imminuta sp. nov.) is described from Daohugou village (Middle Jurassic), Inner Mongolia, China. In this new species, MA forks at the same level as the separation of Rs2 from Rs, close to the middle of forewing, this structure of MA is peculiar in Grammolingiidae and is different from that of all other known species. Moreover, this new species is the smallest species known in the family Grammolingiidae (30 mm wing span).
