Ancyronini Kolibáč, J. 2006: 127.

Type genus.

Ancyrona Reitter, 1876 [designated by Kolibáč 2006]

Kolibáč, J. 2007a: 365. Kolibáč, J. & Zaitsev, A. A. 2010: 59 (phylogeny, larval morphology)

Remarks.

Ancyronini are undeniably related to Lophocaterini . As observations made upon the recently recorded Ancyrona diversa larva have shown ( Kolibáč and Zaitsev 2010), the major morphological features of known larvae of the two tribes are nearly identical. In fact, it is likely that Ancyrona and allied genera are simply "advanced lophocaterins" adapted to a predatory way of life. Such a life-style is clearly demonstrated by their carnivorous mouthparts in both adults and larvae (sharp mandibles without mola), different life habits (they dwell on bark, branches or logs hunting for other insects) and well as their excellent capacity for rapid flight and swift reactions to intrusive stimuli. From the point of view of phylogenetic taxonomy, it appears that Lophocaterini are paraphyletic in relation to Ancyronini ; both tribes are therefore in acute need of further study.
