The species of Ninomimus Lindberg, 1934 are reviewed. A new species, Ninomimusfuscus sp. nov., is described from Hunan Province, China. It differs from its two congeners in its shiny body and translucid hemelytra. A diagnosis of the genus, a key to the included species, photographs of habitus and male genitalia of selected species, and micrographs of the pruinose area of the type species are also presented.

The insect genus Carulaspis MacGillivray, associated with Pinidae and Magnoliidae, includes six species: C.juniperi, C.minima, C.visci, C.atlantica, C.taxicola and C.silvestrii. The first description of C.silvestrii lacks key morphological features that are of paramount importance for species identification. Carulaspissilvestrii type specimens also remain undiscovered, suggesting a potential loss of taxon information. This study provides a detailed redescription of C.silvestrii, including drawings, SEM images and neotype designation for taxonomic stability. For the first time, molecular characterization of C.silvestrii was made using a partial 28S ribosomal gene. In addition, a morphological key for distinguishing species of Carulaspis is provided to aid the scientific community in taxonomic and identification endeavors.

We describe herein a previously unknown species of bark beetle, Phloeosinusmetasequoiae Ning, sp. nov., which was discovered in the Xingdoushan National Nature Reserve, Hubei Province, China. This new species can be distinguished from other species in the genus Phloeosinus Chapuis, 1869 by its deeply emarginate compound eyes, coarse frontal and prothoracic surfaces, reticulate texture, and deeply V-shaped basal margin of the elytra. Phylogenetic analyses based on the cytochrome oxidase I (COI) and the large nuclear ribosomal subunit (28S) genes indicated that the new species represents an independent lineage with the closely related Phloeosinusaubei (Perris, 1885), to which it has a 95% similarity. The new species is known only from the type locality. Diagnoses, descriptions, photographs, and a distribution map are presented, along with a description of host plant damage.

Cladocerafulvipennis Jacoby is transferred to Afrotropicaltica gen. nov., here described. The new genus belongs to the group of Afrotropical genera traditionally attributed to the Blepharida group: Blepharidina Bechyné, Calotheca Heyden, Diamphidia Gerstaecker, Polyclada Chevrolat, and Xanthophysca Fairmaire. A diagnostic key to these genera, and the list of species currently attributed to Diamphidia and Polyclada are provided based on type material and original species descriptions. Species and genera whose taxonomic position needs a revision were identified. Finally, the following synonymy is proposed: Cladocerafulvipennis Jacoby, 1895 = Blepharidafavareli Achard, 1922, syn. nov.

Dexopolleniaguangxiensis Liu, Li & Yao, sp. nov., Dexopolleniachongqingensis Liu, Li & Yao, sp. nov. and Xanthotryxushuapingensis Liu, Li & Yao, sp. nov. from the Guangxi Zhuang Autonomous Region and Chongqing are described and illustrated. Keys to species of the genera Dexopollenia and Xanthotryxus from China are provided. Photographs of the habitus and male genitalia of the new species are also provided.

The Caspian barbastelle, Barbastellacaspica, has spread widely in the Caspian region, Iran, and Central Asia; however, there is no evidence of its occurrence in China so far. During a field investigation, we collected a single specimen of B.caspica in China's Xinjiang Uyghur Autonomous Region. At the same time, we obtained the free-flight echolocation calls of the bat. It omitted signals with start frequency of 33.15 ± 1.43 kHz, end frequency of 29.82 ± 0.40 kHz, frequency of most energy 31.48 ± 0.40 kHz, duration of 2.43 ± 0.24 ms, and a pulse interval of 246.57 ± 9.48 ms, which are probably type-I sounds emitted through the mouth. We also sequenced its entire mitochondrial genome to elucidate the genomic structure and its evolutionary relationships with closely related Barbastella. The mitochondrial genome of B.caspica spans 16,933 bp, comprising 13 protein-encoding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a displacement loop/control region. Consistent with previous bat mitogenome reports, the majority of mitochondrial genes are encoded on the heavy chain. A phylogenetic analysis based on 13 protein-coding genes revealed that Rhogeessa, Plecotus, and B.caspica formed a clade within Vespertilionidae. Barbastellacaspica was found to be a sister species to B.beijingensis and B.leucomelas in phylogenetic trees using the cytochrome b and ND1 gene sequences. This is the first report of the mitogenome of a member of the genus Barbastella, as well as the first record of the distribution of B.caspica in China and first documentation of its echolocation calls.

In the eastern Great Lakes region of North America, two tiger swallowtail species have previously been recognized, Papilioglaucus Linnaeus, 1758 and Papiliocanadensis Rothschild & Jordan, 1906. A third entity, the Midsummer Tiger Swallowtail, has been treated as a P.glaucus×canadensis hybrid, and exhibits a mosaic of both intermediate and unique morphological and biological traits. Here we demonstrate that rather than being a localized, historically recent hybrid phenomenon, the Midsummer Tiger Swallowtail maintains its morphological and physiological distinctness over a large geographic region in the absence of one or both putative parental species, and was first documented in the literature nearly 150 years ago. Papiliosolstitius sp. nov. is physiologically unique in delaying post-diapause development, which results in allochronic isolation between the spring flights of P.glaucus and P.canadensis, and the late summer flight of P.glaucus. Similarly, the geographic range of Papiliosolstitius spans the region between the northern terminus of P.glaucus and southern limits of P.canadensis, remaining distinct in areas of sympatry. Defining the taxonomic identity of this unique evolutionary lineage provides an important baseline for further inquiry into what has served as an exemplary species group in evolutionary study.

Within the diverse genus Lasioglossum, the subgenus Eickwortia as currently understood, encompasses three characteristic species from mountainous areas in Mexico and Central America. Prior to this work only Lasioglossum (Eickwortia) nycteris had descriptions for both male and female. Here we describe and illustrate the previously unknown males of L. (E.) hienae and L. (E.) alexanderi, providing new distributional data for both species, and an updated species identification key for the group.

In the search for specific natural enemies to control two invasive aquatic plants (IAP) from South America, Ludwigiagrandiflorasubsp.hexapetala (Onagraceae) and Myriophyllumaquaticum (Haloragaceae), taxonomic challenges associated with two Lysathia Bechyné, 1959 (Chrysomelidae; Alticini) species had to be resolved. Lysathiaflavipes (Boheman, 1859) exhibits significant morphological variation, causes heavy damage to both IAPs, and may represent more than one species due to the phylogenetic gap between hosts. Additionally, an undescribed Lysathia species (previously published as Lysathia sp.), sourced from Brazil, has been successfully used as a control agent for M.aquaticum in South Africa since 1994. An integrative taxonomic approach combining genetic and morphological analyses was employed. A lectotype and paralectotypes for Graptoderaflavipes Boheman, 1859 are here designated. Phylogenetic studies revealed that L.flavipes had greater genetic and morphological variation than originally described, and no evidence suggested that L.flavipes represented a species complex associated with its host plants. As a result, the species description was expanded. On the other hand, genetic and morphological differences such as body size, colouration, and genital structures further supported the description of Lysathiacilliersae Cabrera, sp. nov. and its differentiation from other closely related species, including L.flavipes and L.ludoviciana (Fall, 1910). Specimens of L.cilliersae sp. nov. collected in Misiones, Argentina, matched those from South Africa. Genetic sequences correlated with morphological vouchers, images, and illustrations of morphology and genitalia, as well as new distribution records, are provided. This research contributes to the taxonomic knowledge of the Lysathia genus and supports accurate species identification in applied entomological contexts, such as biological control programmes.
