Phylogeny of Paussus L. (Carabidae: Paussinae): unravelling morphological convergence associated with myrmecophilous life histories
SYSTEMATIC ENTOMOLOGY(2017)
摘要
. Ant nest beetles (PaussusL.) are ecologically fascinating and phenotypically bizarre. Obligate myrmecophiles, Paussus have undergone extreme adaptations for life with ants and their profound range of phenotypic diversity has been difficult to reconcile in a systematic framework. We conducted a detailed morphological study of Paussus utilizing novel techniques and character systems in order to discover anatomical apomorphies diagnostic of the major clades of Paussus strongly supported by molecular data. Bayesian inference (BI) of molecules alone, morphology alone and varying combinations of the two data types reveal that morphology is informative for placing Paussus species, despite the extreme phenotypic diversity and convergence prevalent in the group. We propose a new classification for Paussus based on this phylogeny. The genus Paussus is revised to include all genera, subgenera and species formerly classified as Paussus by Nagel (2003) in addition to Hylopaussussyn.n., Hylotorussyn.n. and Granulopaussussyn.n. The following species are transferred to Paussus: Paussus sebakuanus (Peringuey) comb.n., Paussus gracilis (Reichensperger) comb.n., Paussus bucephalusGyllenhal, Paussus caroli (Reichensperger) comb.n., Paussus uelensis (Reichensperger) comb.n., Paussus hottentottus (Westwood) comb.n., Paussus blanchardi (Raffray) comb.n., Paussus basilewskyi (Luna de Carvalho) comb.n., Paussus granulatusWestwood, Paussus sankuruensisReichensperger, Paussus leleupi (Reichensperger) comb.n., Paussus reichenspergeri (Luna de Carvalho) comb.n. We formally delineate and diagnose the following major subgroups of Paussus: PaussusI series, comprising the subgenera BohemanipaussusLuna de Carvalho stat. rev. sensu n., BathypaussusWasmann stat. rev. sensu n., and EdaphopaussusKolbe stat. rev. sensu n.; the PaussusII series comprising the subgenera PaussusL. stat. rev. sensu n., KlugipaussusKolbe stat. rev. sensu n., ScaphipaussusFowler stat. rev. sensu n., HylotorusDalman stat.n. sensu n., and AnapaussusWasmann stat. rev. sensu n.; and the PaussusIII series comprising the subgenera LineatopaussusKolbe stat. rev. sensu n. and ShuckardipaussusKolbe stat. rev. sensu n.
