Popis: Vates phoenix sp. nov. urn:lsid:zoobank.org:act: EB7BB1D8-786F-401C-B408-2D41260C7797 Figs 2���5, 6 A���H, 8���9; Table 1 Diagnosis The new species can be easily recognized by the following combination of characters: i) cuticular projections above lateral ocelli strongly reduced (almost entirely missing in some specimens); ii) antennomeres of males asymmetrical (s-shaped); iii) hindwing of females with large, yellowish white and partially opaque area that spreads over most or part of the membrane; iv) anterodorsal lobe of hind tibiae at least 50% the length of tibial length (i.e., not narrowly restricted to its middle section). Etymology The specific epithet refers to the Phoenix, a mythical, immortal creature that is born again from its own ashes after being consumed by fire. The new species is a homage to the Museu Nacional of Rio de Janeiro, which was destroyed during a massive fire on September 2, 2018. The entire entomological collection, representing more than 5 million specimens, was destroyed, including all praying mantis specimens. Only a few specimens of Vates borrowed in the context of this study, including our new species, survived the event. Vates phoenix sp. nov. thus symbolically attempts to link the past and the future of the Museu Nacional, as it represents the rebirth of the Mantodea collection and our hopes for the revival of an even stronger institution in the not too distant future.

MESO- AND METATHORACIC LEGS. Mesothoracic femora (Fig. 6E) with a marked posteroventral keel that forms two evident lobes: a proximal one that is elongated but scarcely produced, and a pre-apical one that is short and produced, shaped like a shark���s dorsal fin. Metathoracic femora (Fig. 6F) with a marked posteroventral keel that forms a single preapical lobe, also shaped like a shark���s dorsal fin.

Fusiform, slightly flattened dorsoventrally, widest between segments III���V, brownish with some contrasting spots in middle of each tergite. Cerci elongated, surpassing apex of subgenital plate, cercomeres cylindrical. Differential diagnosis Svenson et al. (2015) listed all species of Vates they considered valid, totaling 13 spp. All these species are herein discussed in relation to our new species. The males of V. phoenix sp. nov. share with those of V. biplagiata Sj��stedt, 1930, V. luxuriosa Beier, 1958, V. amazonica (Westwood, 1889), V. pectinicornis (St��l, 1877), V. foliata (Lichtenstein, 1802) and V. lobata (Fabricius, 1798) the asymmetrical, s-shaped antennomeres, whereas the females share with those of V. serraticornis St��l, 1877, V. festae Giglio-Tos, 1914, V. weyrauchi Beier, 1958, and likely also V. boliviana Giglio-Tos, 1914 (which remains known from males only) the yellowish white tinge of the hindwing membrane. None of the preceding species has both males with s-shaped antennomeres and females with yellowish white hindwings. Therefore, V. phoenix sp. nov. possesses a unique combination of character states unknown in other species of Vates, making its identification straightforward. In the absence of either one of the sexes for effective comparisons, the reduced ocellar tubercles of V. phoenix sp. nov. represent a distinct character state for the species, common to both sexes, and unique among members of the genus (compare, for instance, with Fig. 6 I���J). Our new species can also be easily distinguished from V. pectinata Saussure, 1871 and V. chopardi (Deeleman-Reinhold, 1957) for lacking the dorsal, preapical lobe of the forefemora, a distinct character shared by the latter two species (Fig. 7) ��� which Roy (2012) suggested as likely synonyms. Additionally, we were unable to compare V. phoenix sp. nov. with the type specimen of Vates lobata (Fabricius, 1798). This species was originally described from ���Cajennae��� (= Cayenne, French Guiana) as Mantis lobata (Fabricius 1798) in the ���Supplementum��� to ���Entomologica Systematica��� ��� not to be confused with Mantis lobata Fabricius, 1781, a synonym of Harpagomantis tricolor (Linnaeus, 1758) (Galinthiadidae) sensu Beier (1934). Examination of the Banks collection (JR) housed by the Natural History Museum, London (containing a sizable portion of Fabricius types) did reveal the presence of Mantis lobata Fabricius, 1781, though no specimen attributable to Mantis lobata Fabricius, 1798 (i.e., Vates) was found there. The taxa that Fabricius (1798) described from ���Cajennae��� in his ���Supplementum��� were owned by Louis Augustin Guillaume Bosc d���Antic (N. Kristensen, pers. com. 2011), a French naturalist whose insect collection, in part studied by Fabricius, dispersed across European natural history institutions after his death in 1828 (Notton 2007). A good portion of this material eventually made it to Paris and Geneva; however, examination of these and other European collections also containing some of Fabricius��� types, such as the Zoological Museum in Copenhagen (N. Kristensen, pers. com. 2011) and the Hunterian Museum in Glasgow (online catalogue: http://collections.gla.ac.uk/) did not turn up any specimen attributable to the type of Mantis lobata Fabricius, 1798. This specimen is most likely lost. Regardless of the fate of the type specimen, the new species can be distinguished from Vates lobata on the basis of its distribution, as French Guiana and Rio de Janeiro are biogeographically distant and unrelated regions that do not share any praying mantis species. Finally, Vates obscura Toledo Piza, 1983, listed as valid in Svenson et al. (2015), had already been synonymized with V. biplagiata in an earlier publication (Agudelo & Rivera 2015), and thus we conclusively remove this species from the Vates checklist. Systematic remarks Morphological comparison of male genitalia provided insights on the affinities of the new species. The only species whose male genital structures are known are Vates chopardi (Lombardo 2000: figs 25���27), and V. biplagiata and V. festae (Medell��n & Salazar 2011: fig. 14). Morphological comparisons between V. phoenix sp. nov. and V. biplagiata genitalia showed that both species share a strong, proximally bent afa, whereas the accentuated sigmoidal shape of the same can also be observed in V. chopardi, though in the latter the afa is not bent to the same degree as in V. biplagiata. Differences in genital structures are more accentuated between V. phoenix sp. nov. and V. festae, the latter with a much straighter afa and, and a shortened and robust Pda on the ventral phallomere. Coincidently, the phylogeny of Vatini proposed in Svenson et al (2015) recovered three main clades within Vates: one containing V. chopardi, sister to another clade comprised of V. festae and V. weyrauchi, altogether sister to a more diverse clade containing V. biplagiata. Our analysis of external morphology and existing reports of male genital structures thus suggests a closer affinity to members of this latter clade, which in Svenson et al. (2015) also included V. luxuriosa, V. amazonica, V. pectinicornis and two additional, unidentified species. Further phylogenetic studies are necessary to test this hypothesis and resolve evolutionary affinities with all members of Vates. With the description of our ne
