Fig. 9 in Phylogeny, classification and taxonomy of European dragonflies and damselflies (Odonata): a review

Fig. 9 Phylogeny of Sympetrum, based on Pilgrim (2006, 2012) and Pilgrim and von Dohlen (2008). Norwegian S. nigrescens and Himalayan S. commixtum are included with S. striolatum following Pilgrim and von Dohlen (2007); Japanese S. frequens with S. depressiusculum following Sawabe et al. (2004). Monophyletic non-European groups not given in detail; three larger groups are detailed on right. The taxa occur in the Eastern Palaearctic and adjacent Oriental Region (EP), Nearctic (NA), Neotropics (NT), entire Palaearctic (PA), Palaeotropics (PT) or Western Palaearctic (WP). Bold species occur in Europe; species classified in subgenus Tarnetrum (* type species) are indicated

Fig. 7 Phylogeny of Libellula (sensu lato), based on molecular data (a, after Artiss et al. 2001; Kambhampati and Charlton 1999) and morphology (b, after Carle and Kjer 2002). B. (Belonia), Eu. (Eurothemis), La. (Ladona), Li. (Libellula sensu stricto) and N. (Neotetrum) are

Fig. 4 in Phylogeny, classification and taxonomy of European dragonflies and damselflies (Odonata): a review

Fig. 4 Inferred phylogeny of global families (a; line thickness is indicative of species diversity; European taxa in bold font) and European genera of Anisoptera (b; see Fig. 6 for details of Libellulidae), based principally on Bybee et al. (2008), as well as Fleck et al. (2008b),

Fig. 3 in Phylogeny, classification and taxonomy of European dragonflies and damselflies (Odonata): a review

Fig. 3 Inferred phylogeny of Ischnura (I.), Enallagma (E.) and associated genera based on preliminary genetic data (Chippindale et al. 1999; Turgeon et al. 2005; Hovmöller 2006; Dumont et al. 2009). Unresolved potentially paraphyletic groups are indicated with broad lines, and known numbers of species in each group are given. The taxa occur in the Nearctic (NA), Neotropics (NT), Palaearctic (PA and bold font) or Palaeotropics (PT). Sampling is very incomplete in Ischnura and the presented hypothesis is therefore tentative. The relationships of numerous (especially Neotropical) ischnurines are unknown, although Hovmöller (2006) found his selection to form the sister group of the assemblage presented here

Fig. 1 in Phylogeny, classification and taxonomy of European dragonflies and damselflies (Odonata): a review

Fig. 1 Inferred phylogeny of global families (a, line thickness is indicative of species diversity, European taxa in bold font) and European genera of Zygoptera (b), based on Bybee et al. (2008), Carle et al. (2008), Dumont et al. (2009) and other sources cited in the text. These

Fig. 2 Phylogeny of European Lestidae, based on molecular data (Dumont et al. 2009; Gyulavári et al. 2011), S. paedisca is placed by default, being the only other European Sympecma species. C. (Chalcolestes), L. (Lestes) and S. (Sympecma) are abbreviations of genera

Fig. 5 in Phylogeny, classification and taxonomy of European dragonflies and damselflies (Odonata): a review

Fig. 5 Phylogeny of Aeshna, Anax and associated genera based on morphology (after von Ellenrieder 2002, 2003). Only bold genera were recognised before the 1990s, the remainder of species being retained in Aeshna (sensu lato). Unresolved paraphyletic groups are indicated with broad lines, and approximate numbers of species in each group are given. The taxa occur in the Afrotropics (AT), Australia (AU), Nearctic (NA), Neotropics (NT), Palaearctic (PA) or Palaeotropics (PT)

FIGURE 5 in Behavioural impacts on the taphonomy of dragonflies and damselflies (Odonata) from the Lower Cretaceous Crato Formation, Brazil

FIGURE 5. Pie charts showing abdominal completeness of Crato Formation Odonate versus other insect orders. A, Pie chart showing the number and percentage of odonate insect fossils examined with varying levels of abdomen preservation. The percentage is of odonates only, not the entire collection examined. B, Pie chart showing the number and percentage of non-odonate insect fossils examined with varying levels of abdomen preservation. The percentage is of non-odonates only, not the entire collection examined.

FIGURE 4 in Behavioural impacts on the taphonomy of dragonflies and damselflies (Odonata) from the Lower Cretaceous Crato Formation, Brazil

FIGURE 4. Principal coordinate analyses of the collection studies. Odonate specimens are connected with a red overlay. Nonodonate specimens are connected with a blue overlay. A, Including both anterior and posterior abdomen characters. B, With the anterior and posterior abdomen characters combined into a single abdomen character. C, Including both anterior and posterior abdomen characters, however three odonate and six non-odonate outliers are excluded in the overlain colours. D, With the anterior and posterior abdomen characters combined into a single abdomen character however two odonate and six non-odonate outliers are excluded in the overlain colours. All analyses use Gower similarity coefficient. Red = Odonata; blue = Blattodea; green = Orthoptera; light blue = Coleoptera; purple = Diptera; light green = Ephemeroptera; black = Hemiptera; yellow = Hymenoptera; orange = Neuroptera; pink = Raphidioptera; grey = Unknown.
