Figure 2A–J in Phylogeny and classification of tribe Aedini (Diptera: Culicidae)
Figure 2A–J. Single most parsimonious cladogram (Fit = 187.51606) obtained from analysis of the data (Appendix 1) under implied weights (K = 9). Numbers on the branches correspond to the characters listed in the data set (Appendix 1). Darkened circles indicate 'unique' character states that can be placed onto the cladogram in only a single position, although they may be interpreted as undergoing subsequent transformation or secondary reversal. Open circles represent homoplastic character states that are placed on more than one branch of the cladogram. Numbers in circles refer to the numbered taxa listed in the legend to Figure 1.

FIGURE 2 in Comparative performance of a multi-locus barcoding approach to enhance taxonomic resolution of New Zealand mosquitoes (Diptera: Culicidae)
FIGURE 2 The statistical parsimony network showing the genetic relationships between Culex asteliae (n = 3), Culex pervigilans (n = 15) and Culex rotoruae (n = 3) based on their (a) COI sequences and (b) ITS2 sequences derived from the current study. Each COI/ITS2 singleton sequence is represented by one circle with size proportional to their frequency. The colours refer to the mosquito species to which each individual belongs. Small white circles connecting coloured circles indicate 'missing' or hypothetical singletons. The line linked two circles indicates one basepair difference on the sequence.
FIGURE 1 in Comparative performance of a multi-locus barcoding approach to enhance taxonomic resolution of New Zealand mosquitoes (Diptera: Culicidae)
FIGURE 1 The phylogenetic relationships of New Zealand endemic and exotic mosquito species based on (a) COI and (b) ITS2 sequences using maximum likelihood method. Anopheles annulipes was outgroup taxon for both trees. Only bootstrap support values greater than 50% is present at branches on the tree. The sequences collected for the current study and derived from New Zealand endemic, introduced or recently eradicated species are highlighted in bold. The specimens collected outside of New Zealand were highlighted by underlines. The complete phylogenetic trees of New Zealand endemic and exotic mosquito species based on COI and ITS2 sequences are available in Figure S3.

The spread of Aedes albopictus (Diptera: Culicidae) in the islands of São Tome and Príncipe
<p>The mosquito <em>Aedes albopictus</em> (Diptera: Culicidae) is a vector species of the causal agents of Dengue, yellow fever, and Zika among other diseases pathogens. The species originated in Southeast Asia and has spread widely and rapidly in the last century. The species has been reported in localities from the Gulf of Guinea since the early 2000s, but systematic sampling has been scant. We sampled <em>Ae. albopictus</em> twice, in 2013 and 2023 across the altitudinal gradient in São Tomé and found that the species was present in all sampled years at altitudes up to 680 meters. We also found some evidence of increases in proportional representation compared to <em>Ae. aegypti</em> over time. We report the presence of the species in Príncipe for the first time, suggesting that the range of <em>Ae. albopictus</em> is larger than previously thought. Finally, we use bioclimatic niche modeling to infer the potential range of <em>Ae. albopictus</em> and infer that the species has the potential to spread across a large portion of São Tomé and Príncipe. Our results suggest that <em>Ae. albopictus</em> has established itself as a resident species of the islands of the Gulf of Guinea and should be incorporated into the list of potential vectors that need to be surveyed and controlled.</p>

Fig. 3 Raincloud plots (i.e. combined violin plots, box plots and dot plots) for the contribution of infected mosquitoes relative to cold or warm months: a for the mosquito pool without dividing into females and males and b separately for females and males, collected in cold (blue) and warm (red) months. The dot plots show the proportion of infected mosquitoes (jittered horizontally). Each dot is the individual proportion of a particular species with a particular sex in a single month. The box plots show the extremes (whisker tails), interquartile range (box boundaries) and median (horizontal line). The violin plots show the probability density of the data. Symbols (asterisks or 'ns') indicate Bonferroni p-value (B) and Holm p-value (H) (B/H). Double asterisks (**) indicate statistical significance at p <0.01; ns, no statistical significance
