Biological invasions increase with the intensity of globalization, human activities, and climate change. Insects represent a high potential of invasive species due to their adaptability to new environment. We analysed here the potential of an Asian phytophagous bug, Corythauma ayyari (Heteroptera, Tingidae) to become widespread, recently recorded in Europe, and that depends on Jasminum spp., an ornamental plant widespread in Europe. We modelled its current distribution, projected it into the future and tested its niche overlap between native and invaded areas. When considering the host plants as environmental variables, the analysis shows that C. ayyari shifted to a new ecological niche but its distribution is restricted by its host plant distribution. Including or excluding the host plants as environmental variables has an impact on C. ayyari distribution. We recommend to consider host plant interactions when dealing with niche modelling of phytophagous species., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Durand, Guilbert.

An annotated catalogue is presented for the type specimens of the peiratine Reduviidae (Hemiptera: Heteroptera) preserved in the Musum National dHistoire Naturelle (MNHN), Paris, France. The Peiratinae collection in MNHN contains type specimens representing 58 nominal species and five varieties (including 48 species and one subspecies currently recognized as valid) of 16 genera. The great majority of the type specimens concerns taxa described by Andr Villiers and Ren Jeannel; there are also several type specimens representing species described by Johann Christian Fabricius, Gustave Fallou and, more recently, Jean-Michel Brenger. The information provided for each taxon and its type specimens includes: original data, type status, label information, type locality, current status and related remarks. Colour images of representative types and their labels are also provided. Specimens of four additional peiratine species, erroneously labelled as Type, are also listed.

Olive lace bugs are small phytophagous Hemipteran insects known to cause agricultural losses in olive production in South Africa. Plerochila australis (Distant, 1904) has been reported as the species responsible for damage to olive trees; however, the diversity of olive lace bug species in the region has lacked attention. Adult olive lace bugs were collected incidentally from wild and cultivated olive trees in the Western Cape Province, and identified as P. australis and Neoplerochila paliatseasi (Rodrigues, 1981). The complete mitochondrial genome of a representative specimen of N. paliatseasi was sequenced, and used for comparative mitogenomics and phylogenetic reconstruction within the family. Furthermore, the value of DNA barcodes for species identification in Tingidae was assessed using genetic clustering and estimates of genetic divergence. The patterns of genetic clustering and genetic divergence of COI sequences supported the morphological identification of N. paliatseasi, and the utility of DNA barcoding methods in Tingidae. The complete mitogenome sequence had the typical Metazoan gene content and order, including 13 PCGs, 22 tRNAs, two rRNAs, and an AT-rich non-coding region. A+T content was high, as commonly found in Tingidae. The phylogenetic reconstruction recovered Agramma hupehanum (Drake Maa 1954) as basal to Tingini, and as a sister species to N. paliatseasi. Stephanitis Stål 1873 and Corythucha Stål 1873 were monophyletic, but Metasalis populi (Takeya 1932) was not recovered as sister to Tingis cardui (Linnaeus 1746), as expected. The mitochondrial phylogeny of the family Tingidae has been recovered inconsistently across different studies, possibly due to sequence heterogeneity and high mutation rates. Species diversity of olive lace bugs in South Africa was previously underestimated. The presence of P. australis was confirmed in both wild and cultivated olives, and N. paliatseasi is reported in cultivated olives for the first time. These results warrant further investigation on the diversity and distribution of olive lace bugs in the Western Cape to inform pest control strategies.

Sexual and natural selection mechanisms might drive variation in the genitalia of male animals. All aforementioned mechanisms are known to predict the coevolution of male and female genital morphology. Belostoma angustum is known to have subtle variation in the male and female genitalia of its members. In this species, phallosoma with dorsal arms and ventral diverticulum are assumed to be intromittent male genital traits that interact with the female genital chamber. We thus evaluated the existence of variation after disentangling the size from the shape of male genitalia in B. angustum. Body and genitalia dimensions and photographs of phallosoma with dorsal arms, ventral diverticulum and lateral views of the right paramere (the non-intromittent part) were obtained. Semi-landmarks and landmarks were used to capture phenotypic variation, by eliminating all non-shape variation with a Procrustes superimposition. Male and female specimens collected from the same location or immediate vicinity were grouped, and 12 groups originating from 12 locations were used to conduct two block-Partial Least Squares analyses (PLS). Group structures were also taken into account by adopting a multilevel approach. The male and female genital traits had similarly shallow static allometry slopes, as well as the dispersion values around the mean (i.e. coefficient of variation) and the standard error of the estimate. The correlation between the pooled within-locality covariance matrix of the symmetric component of phallosoma with dorsal arms and the female genital chamber was significant (r-PLS=0.37), as well as that with male body dimensions (r-PLS=0.36), even after controlling for allometry. Specimens with lower PLS shape scores had narrower phallosoma with dorsal arms, with poorly curved outer margins of the dorsal arms, whereas specimens with higher PLS shape scores had slightly shorter dorsal arms, with strongly curved outer margins. Lower shape scores were associated with narrower and especially shorter and narrower female genital chambers. Similar shallow allometric curves among sexes and the correlation between intromittent male parts and the female genital chamber, as well as male dimensions, suggest the coevolution of these contact structures in size and in shape., (Copyright © 2019 Elsevier GmbH.

Eight species new to science are described from Thailand and 35 species new to Thailand are recorded. The fauna of Thailand, represented formerly by 12 species is increased to 52 species here. Comments on their distribution are added. Most of the species recorded come from material collected in the mid XXth century and deposited in Museums and from recent collecting surveys.

From the Upper Cretaceous Burmese amber, only three genera and species of Tingidae, (Spinitingis ellenbergeri and Burmacader multivenosus Heiss Guilbert, 2013; Tingiometra burmanica Heiss et al. 2015), are reported to date. A new species Burmacader lativentris sp.nov. is described and illustrated.

In the frame of recent field collecting surveys, four species of Tingidae (Insecta: Heteroptera) new to Vietnam are recorded and three species new to science are described, namely Nectocader vietnamensis, Cetiothucha constanti, and Oncophysa hae. The diversity and richness of Vietnamese Tingidae is discussed, considering the locations visited versus the number of species discovered.

Species of Belostoma in the dentatum and subspinosum groups are large and closely related, and have been combined by some authors into a single group, the dentatum group, comprising 15 species. This group is recognized by the scutellum reaching the nodal line and the ventral diverticulum of the phallus with distinct dorsal caudal and ventroapical protuberances. Previously, each group included five and 10 species, respectively; members of the dentatum group ranged in length from 38.0 to 52.0 mm, whereas those of the subspinosum group ranged from 26.0 to 40.0 mm. The following species of the dentatum group, now reformulated, include: Belostoma anurum (Herrich-Schäffer), B. asiaticum (Mayr), B. bordoni De Carlo, B. cummingsi De Carlo, B. columbiae Lauck, B. dallasi De Carlo, B. dentatum (Mayr), B. elongatum Montandon, B. ellipticum Latreille, B. foveolatum (Mayr), B. guianae Lauck, B. harrisi Lauck, B. malkini Lauck, B. porteri De Carlo, B. pseudoguianae Roback & Nieser, B. subspinosum Palisot de Beauvois, and B. venezuelae Lauck. Belostoma bordoni is herein included in the dentatum group based on male genitalic morphology, and the subspecies B. subspinosum subpinosum (Palisot de Beauvois) and B. subspinosum cupreomicans (Stål) are synonymized as a single valid species, B. subspinosum. Belostoma peruvianum De Carlo is synonymized with B. dentatum. Based on the study of male genitalic characteristics, B. cachoeirinhensis Lanzer-de-Souza appears to be conspecific with B. cummingsi; however, because we could not borrow types of B. cachoeirinhensis, we do not synonymize it. Sketches of specimens identified either as B. boscii (Le Peletier de Saint-Fargeau & Serville) or B. anurum by A.L. Montandon from Muséum National d'Histoire Naturelle are provided with comments in order to show the variation of male genitalia through the B. subspinosum complex. Our findings suggest that the dorsal arms of the phallotheca curved apically to be diagnostic of this complex. No firm conclusion is possible because of the great variation in the male genitalia; however, the general aspect of the ventroapical protuberance together with the dorsal arms provide some definition of B. subspinosum. A key to these species is also given, deeply modified after D.R. Lauck and N. Nieser.

Aquatic and semi-aquatic bugs (Heteroptera) represent a remarkable diversity and a resurging interest has been given to documenting at the species level these insects inhabiting Cameroon in Central Africa due to their potential implication in the transmission of the bacterium Mycobacterium ulcerans, the causal agent of Buruli ulcer, an emerging human disease. A survey was carried out over two years in Cameroon. Morphological analyses were done in two steps. A first step consisted in separating the specimens based on broadly shared characters into morphotypes. The specimens were then separated into two independent batches containing each the same representation of each morphotype. One batch (309 specimens) was used by taxonomy experts on aquatic bugs for species level identification and/or to reconcile nymph with their corresponding adult species. The second batch (188 specimens) was used to define species based on the COI DNA sequences (standard sequence used for "DNA barcoding") and using the Automatic Barcode Gap Discovery (ABGD) method. The first morphological analysis step separated the specimens into 63 different morphotypes (49 adults and 14 nymphs), which were then found to belong to 54 morphological species in the infra-orders Gerromorpha and Nepomorpha based on the species-level morphological identification, and 41-45 putative molecular species according to the gap value retained in the ABGD. Integrating morphology and "DNA barcoding" reconciled all the specimens into 62 aquatic bug species in Cameroon. Generally, we obtained a good congruence between species a priori identified based on morphology from adult morphotypes and molecular putative species. Moreover, molecular identification has allowed the association of 86% of nymphs with adults. This work illustrates the importance of integrative taxonomy.

The bug Gyaclavator kohlsi Wappler, Guilbert, Wedmann et Labandeira, gen. et sp. nov., represents a new extinct genus of lace bugs (Insecta: Heteroptera: Tingidae) occurring in latest early Eocene deposits of the Green River Formation, from the southern Piceance Basin of Northwestern Colorado, in North America. Gyaclavator can be placed within the Tingidae with certainty, perhaps it is sistergroup to Cantacaderinae. If it belongs to Cantacaderinae, it is the first fossil record of this group for North America. Gyaclavator has unique, conspicuous antennae bearing a specialized, highly dilated distiflagellomere, likely important for intra- or intersex reproductive competition and attraction. This character parallels similar antennae in leaf-footed bugs (Coreidae), and probably is associated with a behavioral convergence as well.

We report on the results of a survey of the Nepomorpha of northern Tunisia, and list twenty-three species belonging to twelve genera and seven families: Nepidae, Ochteridae, Corixidae, Micronectidae, Naucoridae, Notonectidae, and Pleidae. These records are based on intensive field surveys during the year 2013 and examination of the entomological collections of the National Museum Natural History of Paris. Ranatra linearis (Linnaeus, 1758) is recorded for the first time from Tunisia. The occurrence of Sigara (Halicorixa) stagnalis stagnalis (Leach, 1817) in Tunisia is confirmed. A preliminary checklist of the Nepomorpha of Northern Tunisia and updated distribution maps for all species treated are provided for further studies.

Tingidae (Hemiptera: Heteroptera) collected in Vietnam by several institutions between 1958 and 2013 continue to yield new information about tropical diversity in this family of insects. Herein, thirty-seven species are newly recorded for Vietnam, and four are described as new to science. Comments on their affinities and distribution are provided, highlighting the biological richness of a rapidly developing country with human impacts.

The genus Ulonemia Drake and Poor, 1937 from China is treated. Three species are described as new to science, namely Ulonemia jingae sp. nov., U. angusta sp. nov., and U. magna sp. nov., as well as a redescription of the known species U. assamensis (Distant, 1903a). Illustrations of habitus and diagnostic characters of these species are provided, together with a key to the species of Ulonemia occurring in the Oriental region.

The Afrotropical Belostomatidae fauna has long proved to be a difficult taxonomic problem, not so much for the overwhelmingly large number of species involved but rather because of a lack of trained specialists. The rarity of some taxa also contributes to confusion, because some species remain poorly described or are known only from one or two specimens. During a visit to the Muséum National d'Histoire Naturelle, Paris, France and the Musée Royal de l'Afrique Centrale, Tervuren, Belgium, it was possible to comprehensively review the Limnogeton species based mainly on the specimens housed in the aforementioned collections. An updated key to adults of all species presently included in the genus, particularly based on male genitalia characters studied during the present study, has been provided.

From the Upper Cretaceous Burmese amber, the first known genera of Tingidae, Spinitingis n. gen. and Burmacader n. gen. with the species Spinitingis ellenbergeri n. sp. and Burmacader multivenosus n. sp., are described and figured. Their systematic placement and relationship to fossil and extant taxa are discussed.

The article presents an application to the International Commission on Zoological Nomenclature (ICZN) to designate a neotype for Belostoma ellipticum Latreille, 1833. The species is said to be a nomen dubium and has been accepted by heteropterists since 1962. The authors referred specimens of several other taxonomically valid taxa to Belostoma ellipticum.

The purpose of this application, under Article 75.5 of the Code, is to designate a neotype for Belostoma ellipticum Latreille, 1833. This species has been accepted by heteropterists since 1962, but it is actually a nomen dubium, since Latreille designated neither types nor a type locality and provided little descriptive information. Subsequent to Latreille, in the absence of a useful diagnosis, authors referred specimens of several other taxonomically valid taxa to B. ellipticum. Belostoma ellipticum sensu Lauck, 1962, however, is readily defined by the presence of a pair of conspicuous notches along the lateral margins of the ventral diverticulum of the phallus in ventral view, and it is this concept of the species that has gained general acceptance. Fixation of a neotype displaying this feature, which cannot be confirmed in any potentially syntypic Latreille specimen of the subspinosum group in Carreno's collection at the Museo Nacional de Ciencias Naturales, Madrid, will facilitate retention of B. ellipticum as a valid species name.
