In our phylogenetic trees, <i>Alloceraea</i> was the sister to <i>Archaeocroton sphenodonti</i>, a tick of an archetypal reptile, the tuatara, from New Zealand, to the exclusion of the rest of the species of <i>Haemaphysalis</i>. The mt genomes of all four of the <i>Alloceraea</i> species that have been sequenced so far had a substantial insert, 132–312 bp, between the tRNA-Glu (E) gene and the <i>nad1</i> gene in their mt genomes. This insert was not found in any of the other eight subgenera of <i>Haemaphysalis</i>. The mt genomes of 13 species of <i>Haemaphysalis</i> from NCBI GenBank were added to the most recent data set on <i>Haemaphysalis</i> and its close relatives to help resolve the phylogeny of <i>Haemaphysalis</i>, including five new subgenera of <i>Haemaphysalis</i> not previously considered by other authors: <i>Allophysalis</i> (structurally primitive), <i>Aboimisalis</i> (structurally primitive), <i>Herpetobia</i> (structurally intermediate), <i>Ornithophysalis</i> (structurally advanced) and <i>Segalia</i> (structurally advanced). We elevated <i>Alloceraea</i> Schulze, 1919 to the status of genus because <i>Alloceraea</i> Schulze, 1919 is phylogenetically distinct from the other subgenera of <i>Haemaphysalis</i>. Moreover, we propose that the subgenus <i>Allophysalis</i> is the sister to the rest of the <i>Haemaphysalis</i> (14 subgenera) and that the ‘structurally primitive’ subgenera Hoogstraal and Kim comprise early diverging lineages. Our matrices of the pairwise genetic difference (percent) of mt genomes and partial 16S rRNA sequences indicated that the mt genome sequence of <i>Al</i>. <i>kitaokai</i> (gb# OM368280) may not be <i>Al</i>. <i>kitaokai</i> Hoogstraal, 1969 but rather another species of <i>Alloceraea</i>. In a similar way, the mt genome sequence of <i>H</i>. <i>(Herpetobia</i>) <i>nepalensis</i> Hoogstraal, 1962 (gb# NC_064124) was only 2% genetically different to that of <i>H</i>. (<i>Allophysalis</i>) <i>tibetensis</i> Hoogstraal, 1965 (gb# OM368293): this indicates to us that they are the same species. <i>Alloceraea cretacea</i> may be better placed in a genus other than <i>Alloceraea</i> Schulze, 1919.

Mosquitoes represent an ideal organism in which to explore the biological effects of microplastics on terrestrial insects, not least because of their importance as an infectious disease vector. Drawing on evidence from other organisms and knowledge of the mosquito life cycle, we summarise some of the more plausible impacts of microplastics including physiological, ecotoxicological and immunological responses.

Wangrawa,&nbsp;Joel O. Odero,&nbsp;Francesco Baldini,&nbsp;Fredros Okumu,&nbsp;Athanase Badolo","doi":"10.1111/mve.12706","DOIUrl":"10.1111/mve.12706","url":null,"abstract":"&lt;p&gt;There has been significant progress in malaria control in the last 2 decades, with a decline in mortality and morbidity. However, these gains are jeopardised by insecticide resistance, which negatively impacts the core interventions, such as insecticide-treated nets (ITN) and indoor residual spraying (IRS). While most malaria control and research efforts are still focused on &lt;i&gt;Anopheles gambiae&lt;/i&gt; complex mosquitoes, &lt;i&gt;Anopheles funestus&lt;/i&gt; remains an important vector in many countries and, in some cases, contributes to most of the local transmission. As countries move towards malaria elimination, it is important to ensure that all dominant vector species, including &lt;i&gt;An. funestus&lt;/i&gt;, an important vector in some countries, are targeted. The objective of this review is to compile and discuss information related to &lt;i&gt;A. funestus&lt;/i&gt; populations' resistance to insecticides and the mechanisms involved across Africa, emphasising the sibling species and their resistance profiles in relation to malaria elimination goals. Data on insecticide resistance in &lt;i&gt;An. funestus&lt;/i&gt; malaria vectors in Africa were extracted from published studies. Online bibliographic databases, including Google Scholar and PubMed, were used to search for relevant studies. Articles published between 2000 and May 2023 reporting resistance of &lt;i&gt;An. funestus&lt;/i&gt; to insecticides and associated mechanisms were included. Those reporting only bionomics were excluded. Spatial variation in species distribution and resistance to insecticides was recorded from 174 articles that met the selection criteria. It was found that &lt;i&gt;An. funestus&lt;/i&gt; was increasingly resistant to the four classes of insecticides recommended by the World Health Organisation for malaria vector control; however, this varied by country. Insecticide resistance appears to reduce the effectiveness of vector control methods, particularly IRS and ITN. Biochemical resistance due to detoxification enzymes (P450s and glutathione-S-transferases [GSTs]) in &lt;i&gt;An. funestus&lt;/i&gt; was widely recorded. However, &lt;i&gt;An. funestus&lt;/i&gt; in Africa remains susceptible to other insecticide classes, such as organophosphates and neonicotinoids. This review highlights the increasing insecticide resistance of &lt;i&gt;An. funestus&lt;/i&gt; mosquitoes, which are important malaria vectors in Africa, posing a significant challenge to malaria control efforts. While &lt;i&gt;An. funestus&lt;/i&gt; has shown resistance to the recommended insecticide classes, notably pyrethroids and, in some cases, organochlorides and carbamates, it remains susceptible to other classes of insecticides such as organophosphates and neonicotinoids, providing potential alternative options for vector control strategies.

To help the morphological recognition of these two species and further explore their differences, we used the geometric morphometric approach applied to the head. Both sexes were examined. Five anatomical landmarks of the head were used, and to capture the curvature of the front head, 10 semilandmarks were added. There was a consistent difference in species classification accuracy when considering landmarks only versus their combination with semilandmarks, suggesting the importance of the curve of the head as a taxonomic signal. Using or not the labels in the reclassification analyses, the head shape allowed by itself almost perfect recognition of the two species, in both sexes, even after adjustment for prior probabilities. The same approach disclosed a high level of sexual size and shape dimorphism in both species. The contribution of size variation to the discrimination by shape was much more important between sexes (from 27% to 45%) than between species (from 0.7% to 7.1%). Nevertheless, in our data, size never could represent a way to reliably recognise the sex of an individual, even less its species. Geographical variation in head shape could only be explored for the <i>C. orientis</i> sample. No significant correlation of morphometric variation with geography could be detected, which would be consistent with gene flow between Thai provinces. The geometric morphometric approach of the flea head, when it incorporates head curves, is a promising tool for rapid, economical, and accurate species and sex identification.
