“…The phylogeny of the most diverse group of Dytiscidae, the Hydroporinae, remains poorly understood (Miller et al., 2006; Michat and Alarie, in press). Several major lineages have been recognized, with, for example, Zimmermann (1930, 1933) considering six tribes: Vatellini, Methlini, Hyphydrini, Hydrovatini, Bidessini and Hydroporini.…”

Dytiscidae is the most diverse family of beetles in which both adults and larvae are aquatic, with examples of extreme morphological and ecological adaptations. Despite continuous attention from systematists and ecologists, existing phylogenetic hypotheses remain unsatisfactory because of limited taxon sampling or low node support. Here we provide a phylogenetic tree inferred from four gene fragments (cox1, rrnL, H3 and SSU, 4000 aligned base pairs), including 222 species in 116 of 174 known genera and 25 of 26 tribes. We aligned ribosomal genes prior to tree building with parsimony and Bayesian methods using three approaches: progressive pair-wise alignment with refinement, progressive alignment modeling the evolution of indels, and deletion of hypervariable sites. Results were generally congruent across alignment and tree inference methods. Basal relationships were not well defined, although we identified 28 well supported lineages corresponding to recognized tribes or groups of genera, among which the most prominent novel results were the polyphyly of Dytiscinae; the grouping of Pachydrini with Bidessini, Peschetius with Methlini and Coptotomus within Copelatinae; the monophyly of all Australian Hydroporini (Necterosoma group), and their relationship with the Graptodytes and Deronectes groups plus Hygrotini. We found support for a clade formed by Hydroporinae plus Laccophilini, and their sister relationship with Cybistrini and Copelatinae. The tree provided a framework for the analysis of species diversification in Dytiscidae. We found a positive correlation between the number of species in a lineage and the age of the crown group as estimated through a molecular clock approach, but the correlation with the stem age was non-significant. Imbalances between sister clades were significant for several nodes, but the residuals of the regression of species numbers with the crown age of the group identified only Bidessini and the Coptotomus + Agaporomorphus clade as lineages with, respectively, above and below expected levels of species diversity.

“…In part because of this, and also to develop a system useful for phylogenetic analysis, a new descriptive template including a system of nomenclature for larval chaetotaxy was devised Alarie 1991;. So far, such descriptive framework was particularly useful in studying 11 genera: Glareadessus Wewalka and Biström, 1998 (Alarie andWewalka 2001), Amarodytes Régimbart, 1900 (Michat and Alarie 2006), Anodocheilus Babington, 1841 (Michat and Torres 2006), Liodessus Guignot, 1939), Hypodessus Guignot, 1939(Michat and Alarie 2008), Neobidessodes Hendrich and Balke, 2009and Hydroglyphus Motschulsky, 1853(Michat et al 2010), Allodessus Guignot, 1953(Michat et al 2011), Limbodessus Guignot, 1939(Michat et al 2012), Brachyvatus Zimmermann, 1919(Michat and Torres 2013, and Yola (this paper). In the following, we summarize the characters potentially useful to separate larvae of Yola from those of other bidessine genera (Table 3).…”

“…Immatures have been underutilized in phylogenetic studies though there is considerable evidence for the utility of characters from larvae (Meier and Lim 2009). As demonstrated over the past recent years, larval chaetotaxy is a particularly significant source of characters for the study of the phylogenetic relationships within Hydroporinae (Michat andTorres 2005, 2008;Michat 2006;Alarie and Michat 2007a;Michat et al 2007;Michat and Alarie 2008). The development of a system of nomenclature to name primary sensilla (setae and pores) in first-instar larvae ofthat subfamily has brought great progress because it allows for exploration of an extensive set of characters that is phylogenetically very useful.…”

ABSTRAGT The phylogenetic relationships and putative monophyly of the diving-beetle tdbe Vatellini are explored based on a cladistic analysis of 37 taxa and 122 chaetotaxic and morphological characters from larvae. For this purpose, larvae of the genus Derovatellus Sharp are descdbed and illustrated in detail, with particular emphasis on morphometry and chaetotaxy, with the later being unexplored until now. The results strongly support the monophyly of the Vatellini based on several unique larval characters. The terminal insertion of the primary seta UR8 on the second urogomphomere in members of Vatellini represents a reversal from the dedved condition. Vatellini was recovered as the sister group of the Australian genus Antiporus Sharp (Hydropodni) based on the presence of: a spatulate nasale, pore PAe and elongate lateral spinulae on prementum. These characters, however, have a reduced value because all of them seem to have evolved several times independently within the Hydroporinae. The tdbe Vatellini and its genera are diagnosed and compared with other hydropodne taxa, and interesting features are discussed. Vatellus Aube is unique within Hydropodnae in the presence of secondary setae on the first antennomere and the first maxillary palpomere, and the one-segmented labial palpus. Derovatellus can be separated from almost every other Hydropodnae by the absence of seta LAI on prementum and of secondary anterodorsal setae on femur.KEY WORDS diving beetles, larvae, phylogenetic relationships, chaetotaxyThe vatellines are a distinctive group among diving range compdsing the Afrotropical, Nearctic, Neotrobeetles in which the adults have evolved certain mor-pical, and Odental regions (Nilsson 2001 ).
