FIGURE 15 in Bunites distigma (Brullé, 1837): discovery of the second- and third-instar larvae and phylogenetic relationships within the Colymbetinae (Coleoptera: Dytiscidae)
FIGURE 15. One of the two most parsimonious cladograms obtained from the cladistic analysis, with character state changes mapped (using ACCTRAN optimization) for all Colymbetinae clades. Numbers in bold underlined indicate character state transformations that are unique within the subfamily.
FIGURES 1–7 in Bunites distigma (Brullé, 1837): discovery of the second- and third-instar larvae and phylogenetic relationships within the Colymbetinae (Coleoptera: Dytiscidae)
FIGURES 1–7. Bunites distigma (Brullé, 1837). (1–3) Adults with different elytral color pattern, dorsal aspect: (1) elytra predominantly black with small ferrugineous macula on external margin very weakly marked; (2) elytra predominantly black with small ferrugineous macula on external margin well marked; (3) elytra black with large ferrugineous macula extending anteriorly and at base. (4–5) Instar III larva: (4) head, dorsal aspect; (5) abdominal segments VII–VIII and urogomphi, dorsal aspect. (6–7) Instar II larva: (6) head, dorsal aspect; (7) abdomen, dorsal aspect. Scale bars = 4 mm for Figs 1–3 and 1 mm for Figs 4–7. For a picture of instar I see Michat et al. (2017).
