(1) Background: Scorpions (Arthropoda: Arachnida) represent a diverse group of invertebrates, accounting for a significant proportion of earth’s predators and ecosystems’ modulators. Surviving mostly in hardly reachable nests, and representing key hazards to human health, they attracted major interest for characterizing their eco-, morpho-, and genotypes. (2) Methods: Four scorpion species were collected from the New Valley governorate in Upper Egypt, where a high level of scorpionism and related neurological symptoms are found, that were Leiurus quinquestriatus, Androctonus amoreuxi, Orthochirus innesi, Buthacus leptochelys. They were DNA barcoded, genetically and phylogenetically analyzed through PCR amplification and sequencing of the mitochondrial cytochrome oxidase subunit 1 (COI) gene hypervariable 5′ region. (3) Results: New, morphologically authenticated scorpion barcodes could be added to the barcoding databases. However, several discrepancies and barcode database inadequacies could be revealed. Moreover, taxon-specific patterns for nitrogenous bases’ distribution could be identified, resulting in a significantly high percentage of COI barcode guanine in scorpionids, in comparison to araneids and opilions. (4) Conclusions: For a group of animals where both cryptic speciation and a high risk of human envenomation are evident, the findings of the current study strongly recommend continuous and comprehensive research efforts dealing with morphogenetic authentication for different species of scorpions.

We identified newly discovered pamphiliid larvae feeding on Cornus in Tochigi and Ibaraki Prefectures, Honshu, Japan, with Pamphilius japonicus Shinohara, 1985, by molecular methods using mitochondrial cytochrome oxidase subunit 1 (COI) gene sequences. The host plant of P. japonicus was unknown. This is the first record of the Cornaceae as a host plant of the Pamphiliidae in the Old World. The larvae were solitary leaf-rollers on Cornus and discovered mainly on small young trees in shadowy forests.

A molecular analysis based on mitochondrial cytochrome oxidase subunit 1 (COI) gene sequences has indicated that larvae collected in Sichuan and Zhejiang Provinces, China, belong to Onycholyda xanthogaster Shinohara, 1999, and O. fulvicornis Shinohara, in Shinohara & Wei, 2016 (Hymenoptera, Pamphiliidae), and that a male Onycholyda specimen from Mt. Tianmushan, Zhejiang Province is the hitherto unknown male of O. tianmushana Shinohara & Xiao, 2006. The first host plant records are Rubus inopertus (Focke) Focke (Rosaceae) for O. xanthogaster and Rubus hirsutus Thunb. for O. fulvicornis. The larvae of O. xanthogaster and O. fulvicornis are briefly described and O. xanthogaster is newly recorded from Sichuan Province. The male of O. tianmushana is described for the first time.

Sarcophaga Meigen, 1826 is proposed as a senior synonym of Cornexcisia Fan & Kano, 2000, syn. nov. and Fanzideia Xue, Verves & Du, 2011, syn. nov. Cornexcisia Fan & Kano, 2000, stat. rev. is given status as a subgenus and is considered a senior synonym of Fanzideia Xue, Verves & Du, 2011, syn. nov. at the subgeneric level. Cornexcisia is argued to contain S. (Cornexcisia) longicornuta (Fan & Kano, 2000), comb. nov., S. (C.) cygnocerca (Xue, Verves & Du, 2011), comb. nov., S. (C.) kurahashii (Shinonaga & Tumrasvin, 1979), subgen. comb. nov. (from Phallosphaera Rohdendorf) and S. (C.) suthep Pape & Bänziger, 2003, subgen. comb. nov. (from Rosellea Rohdendorf). Sarcophaga (C.) kurahashii is newly recorded from China (Yunnan), the male is redescribed and the female is described for the first time, supported by photographs, illustrations and mitochondrial cytochrome oxidase subunit I (COI) gene sequences. Species of Cornexcisia share an exceptionally long postpedicel in the female and the following apomorphic distiphallic appendages in the male: juxta ventro-proximally with an apically divided arm with cuticular pile, and lateral styli bifurcated from the base with each branch elongate, gently curved and slightly expanded apically. A key to the species of Cornexcisia is provided.

Work on two freshwater Gobi fish species such as Awaous guamensis and A. grammepomus was carried out on morphometric and meristic study for their morphological identification. Sequence data of mitochondrial cytochrome oxidase subunit I (COI) gene was used for this purpose. Around 620 bp sequences were obtained when universal primers were used. An alignment was performed between the sequences which showed some inter-specific variation. An entropy plot was generated for all the aligned positions which showed that the entropy rarely touches a scale of one, which is a sign of better alignment in the region. This work can be utilized for species identification, phylogenetic analysis, to study molecular diversity and evolution, and most importantly for the conservation of these fauna in near future.

Primer plays an important role in studying genetic diversity of an insect species. This research was aimed to select the suitable primers to visualize the genetic diversity of Asian corn borer (Ostrinia furnacalis) using Random Amplified Polymorphic DNA (RAPD), microsatellite, and mitochondrial cytochrome oxidase subunit 1 gene (mtCO1). Twenty four RAPD primers (OPA1, OPA4, OPA7,OPA8, OPA10, OPA11, OPA12, OPA13, OPB7, OPB10, OPB11, OPB12, OPB15, OPC4, OPC5, OPC14, OPC16, OPC18, OPC20, OPD3, OPD8, OPD10, OPD13, OPD14) and five microsatellite primers (T3, T4, T5, T81, D25) resulted high polymorphic informations of the genetics of O. furnacalis in Java Indonesia. Universal primers, Lep and Heb were appropriateto do molecular identification of O. furnacalis based on BLAST system on GenBank and BOLD systems.

AbstractThe genus Encarsia Förster includes parasitoid species that are effective natural enemies of whitefly and armoured scale insect agricultural pests. Within this genus, several species groups have been recognized on the basis of morphological similarity, although their monophyly appears uncertain. It is often difficult to separate morphologically similar species, and there is evidence that some species could in fact be complexes of cryptic species. Their correct identification is fundamental for biological control purposes. Recently, due to unreliability of morphological characters, molecular techniques have been investigated to identify markers that differentiate closely related species. In this study, DNA variation in an ~900 bp segment of the mitochondrial cytochrome oxidase subunit I (COI) gene was examined by both sequencing and PCR–RFLP. Two pairs of species that are difficult to distinguish morphologically were analysed: Encarsia formosa Gahan and Encarsia luteola Howard, belonging to the luteola group, and two populations of Encarsia sophia (Girault & Dodd) from Pakistan and Spain, belonging to the strenua group, recently characterized as cryptic species. High sequence divergence and species-specific restriction patterns clearly differentiate both species pairs. Parsimony analysis of the nucleotide sequences was also performed, including Encarsia hispida De Santis (luteola group) and Encarsia protransvena Viggiani (strenua group). Two monophyletic clades supporting the two groups of species considered were resolved. The results of this study support the use of the COI gene as a useful marker in separating species of Encarsia, for which morphological differences are subtle. Moreover, the COI gene appears potentially useful for understanding phylogenetic relationships in this genus.
