Figure 7 in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 7. Labial palps of: A, D. pruininus; B, D. belfragei; C, D. knisleyi sp. nov. A and B illustrate labial palps with a contrasting darker apical segment, and C illustrates labial palps that are consistently dark throughout.
Figure 3 in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 3. Distribution of sampled Dromochorus populations. Colours correspond to those used in Figure 1. Green = D. pilatei, pink = D. welderensis sp. nov., sky blue = D. velutinigrens, red = D. chaparralensis sp. nov., blue = D. pruininus, lime green = D. knisleyi sp. nov., orange = D. minimus sp. nov., black = D. belfragei.
Figure 1 in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 1. Number of new North American tiger beetle species described by decade, from 1766 to the present, as generally accepted in recent treatments of the North American fauna (e.g. Freitag, 1999; Pearson et al., 2006; Pearson et al., 2015).
Figure 6 in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 6. Boxplots, by species, from morphometric data used in principal component analyses (PCA) for each of 411 individuals. PCA indicated three measurements: PC1, overall body length; PC2, shape of the pronotum; and PC3, elytral length to body length ratio, to explain 92–95% of the total variation in the dataset. Shown are targeted comparisons among two main phylogenetic groups: 1, the D. minimus–D. velutinigrens–D. welderensis–chaparralensis group; and 2, the D. knisleyi– D. belfragei–D. pruininus clade. Species labelled with the same letters did not differ significantly from each other, species labelled with 'ab' did not differ between other species which were significantly different. Percentages are relative contributions per analyses, and group; outliers are shown as black dots.
Figure 8. A in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 8. A, Elytra showing distinct punctures (foveae) running parallel to the suture of the elytra (D. knisleyi sp. nov.). B, lack of distinct subsutural foveae (D. welderensis sp. nov.).
Figure 4 in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 4. Unrooted population-level tree based on 61 890 GBS loci, constructed using the Fitch–Margoliash method in PHYLIP. Each branch of the tree represents a single geographic locality. Colours are as in Figures 2, 3.
Figure 5 in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 5. STRUCTURE plots based on dataset of 5000 random GBS loci. Each locus was present in at least two populations and present at greater than 75% of individuals in those populations. K-values determined by STRUCTURE Harvester (Earl & vonHoldt, 2012) are shown at left of the population assignments for each value, and as delta-K estimations across all values. The collection localities that correspond to the columnar groups of specimens determined by the population assignments appear at bottom with the end of the phrase adjacent to its columnar group in all assignments. Left panel, K = 2–4 for 'velutinigrens group'. Delta-K plot indicated that K = 4 is the best supported explanation for the data. Right panel, K = 2–5 for 'belfragei group'. Delta-K plot indicated that K = 4 is the best-supported explanation for the data.
Figure 9 in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 9. Dorsal habitus for species of Dromochorus. A, D. pruininus; B, D. belfragei; C, D. knisleyi sp. nov.; D, D. minimus sp. nov.; E, D. chaparralensis sp. nov.; F, D. welderensis sp. nov.; G, D. velutinigrens; H, D. pilatei.
Figure 2B in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 2B. This section of the mitochondrial genealogy focuses on clades historically considered to be part of a single species: Dromochorus belfragei. Notable is the mixed clade of specimens of D. knisleyi and D. belfragei collected from the only area where both species are known to occur.
Figure 2A in Cryptic diversity in the North American Dromochorus tiger beetles (Coleoptera: Carabidae: Cicindelinae): a congruence-based method for species discovery
Figure 2A. Mitochondrial DNA (mtDNA) cytochrome oxidase b (Cytb) Bayesian genealogy of all members of the genus Dromochorus. Outgroups include North American representatives of Cylindera and Cicindelidia. On the left is a reduced version of the full tree indicating clades shown, in detail, in each figure. Colours are arbitrarily chosen to show distinctions among the taxa, and directly correspond to populations shown in Figure 3. Only posterior support values above 60 are displayed, and the scale bar at bottom shows a branch length representing nucleotide substitutions per site. Taxon names include the unique specimen number (see also Supporting Information, Table S1), along with the state and collection locality; genomic material from specimens marked with a ~ were also used in the multilocus analysis (Figure 4), and holotypes of species described in this work are marked with an 'H'. The longitudinal bars on the right identify specimens and clades historically considered to be a single species.
