Revision of the lacewing genus Laccosmylus with two new species from the Middle Jurassic of China (Insecta, Neuroptera, Saucrosmylidae).

ABSTRACT: The genus Laccosmylus Ren & Yin, 2003 belonging to Saucrosmylidae was erected by using a single hind wing only. Based on new fossil material and re-examination of the type specimen, the diagnosis of the genus is emended with supplementary forewing characters, reported for the first time. In addition, two new species Laccosmyluscicatricatus sp. n. and Laccosmyluslatizonus sp. n. are described.

Revision of the Neotropical green lacewing genus Ungla (Neuroptera, Chrysopidae).

Project description:Here, Ungla Navás, 1914, a poorly known Neotropical genus is reviewed. Twenty-five valid species are recognized; seven of them are new to science: Ungla adamsisp. n., U. elbergisp. n., U. grandispiraculasp. n., U. mexicanasp. n., U. pennyisp. n., U. quchapampasp. n., U. stangeisp. n.; and five are transferred to Ungla from other genera: U. bolivari (Banks), U. chacranella (Banks), U. siderocephala (Navás), U. steinbachi (Navás), and U. banksi Tauber, new replacement name. In addition, ten new synonymies are identified. For each species, a full nomenclatural history, diagnosis, description or redescription with images, literature citations, and available information on the distribution and biology are provided. Name-bearing types were examined for each species, and images of most are included. Keys based on external features are provided for species identifications. As a result of this study, three generalizations appear: (1) The genital morphology of both males and females of Ungla species is very conserved. All species express a common structural pattern, the components of which vary only slightly among species. (2) Ungla species appear to fall into two geographically distinct groups: about one third (n=7) of the species are recorded from southern South America (specifically Argentina and Brazil) and the other approximately two thirds of the species (n=18) from more northern regions of Neotropical America [Andean and Caribbean regions, Central America, and southern Mexico (Chiapas)]. None of the species from either of the regions is known to overlap into the other region. (3) Available information on the immature stages and natural history of species in Ungla is meagre.

Two new species of Sinosmylites Hong (Neuroptera, Berothidae) from the Middle Jurassic of China, with notes on Mesoberothidae.

Project description:Two new species of the genus Sinosmylites Hong are described from the Middle Jurassic locality at Daohugou (Inner Mongolia, China): Sinosmylites fumosussp. n. and Sinosmylites rasnitsynisp. n. This is the oldest known occurrence of the family Berothidae. The berothid affinity of this genus is confirmed by examination of the hind wing venation characteristic of the family. The Late Triassic family Mesoberothidae may represent an early group of Berothidae.

Four new species of hangingflies (Insecta, Mecoptera, Bittacidae) from the Middle Jurassic of northeastern China.

Project description:Two new species of Mongolbittacus Petrulevi?ius, Huang & Ren, 2007, Mongolbittacusspeciosus sp. n. and Mongolbittacusoligophlebius sp. n., and two new species of Exilibittacus Yang, Ren & Shih, 2012, Exilibittacusfoliaceus sp. n. and Exilibittacusplagioneurus sp. n., in the family Bittacidae, are described and illustrated based on five well-preserved fossil specimens. These specimens were collected from the late Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. These new findings enhance our understanding of the morphological characters of early hangingflies and highlight the diversity of bittacids in the Mid Mesozoic ecosystems.

Revision of the green lacewing subgenus Ankylopteryx (Sencera) (Neuroptera, Chrysopidae).

Project description:The Australasian and Oriental green lacewing subgenus Ankylopteryx (Sencera) Navás (Chrysopinae: Ankylopterygini) is examined and its diversity and placement among other members of the tribe Ankylopterygini is discussed. After study of specimens spanning the full distribution and anatomical range of variation for the subgenus, all prior putative species, resulting in the sole valid species are newly synonymized, Ankylopteryx (Sencera) anomala (Brauer). Accordingly, the following new synonymies are established: Sencera scioneura Navás, syn. n., Sencera feae Navás, syn. n., and Sencera exquisita Nakahara, syn. n. [all under the name Ankylopteryx (Sencera) anomala]. A lectotype is newly designated for Ankylopteryx (Sencera) anomala so as to stabilize the application of the name. To support our hypotheses, the wing and general body coloration as well as the male genitalia are reviewed. We elaborate on the possibility of Ankylopteryx (Sencera) anomala being nothing more than an autapomorphic species of Ankylopteryx Brauer, as it was originally described. The species is not sufficiently distinct to warrant recognition as a separate subgenus within the group, and most certainly not as its own genus as has been advocated by past authors. Nonetheless, we do not for now go so far as to synonymize the subgenus until a more extensive phylogenetic analysis is undertaken with multiple representative species from across Ankylopteryx and other ankylopterygine genera. Lastly, we comment on the biology of Ankylopteryx (Sencera) anomala in terms of the attraction of males to methyl eugenol and on the widespread practice of splitting within Chrysopidae.

A new fossil silky lacewing genus (Neuroptera, Psychopsidae) from the Early Cretaceous Yixian Formation of China.

Project description:A new genus and species, Undulopsychopsis alexigen. 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 Undulopsychopsisgen. 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).

Comparative mitogenomic analysis reveals sexual dimorphism in a rare Montane lacewing (Insecta: Neuroptera: Ithonidae).

Project description:Rapisma McLachlan, 1866 (Neuroptera: Ithonidae) is a rarely encountered genus of lacewings found inmontane tropical or subtropical forests in Oriental Asia. In Xizang Autonomous Region (Tibet) of China there are two sympatrically distributed species of Rapisma, i.e. Rapisma xizangense Yang, 1993 and Rapisma zayuanum Yang, 1993, in which R. xizangense is only known as male and has dull brownish body and wing coloration, while R. zayuanum is only known as female and has bright green body and wing coloration. In order to clarify the relationship between these two species, we determined the complete mitochondrial (mt) genomes of R. xizangense and R. zayuanum for the first time. The mt genomes are 15,961 and 15,984 bp in size, respectively, and comprised 37 genes (13 protein coding genes, 22 tRNA genes and 2 rRNA genes). A major noncoding (control) region was 1,167 bp in R. xizangense and 1,193 bp in R. zayuanum with structural organizations simpler than that reported in other Neuropterida species, notably lacking conserved blocks or long tandem repeats. Besides similar mitogenomic structure, the genetic distance between R. xizangense and R. zayuanum based on two rRNAs and 13 protein coding genes (PCGs) as well as the genetic distance between each of these two Tibetan Rapisma species and a Thai Rapisma species (R. cryptunum) based on partial rrnL show that R. xizangense and R. zayuanum are most likely conspecific. Thus, R. zayuanum syn. nov. is herein treated as a junior synonym of R. xizangense. The present finding represents a rare example of distinct sexual dimorphism in lacewings. This comparative mitogenomic analysis sheds new light on the identification of rare species with sexual dimorphism and the biology of Neuroptera.
