Comparative morphological study of † Kyromyrma (∼92 Ma, New Jersey amber; Grimaldi & Agosti, 2000 ) at the gross ( Figs 8L , 9K ) and fine scales reveals considerable morphological affinity to Lasius (holotype examined at AMNH). In the original description of † Kyromyrma , the authors did not address the problem of within-subfamily placement, merely noting that ‘the fossil bears an overall resemblance to Prolasius , mostly by virtue of the generalized morphology’ ( Grimaldi & Agosti, 2000 , p. 13681). Our combined evidence analyses resulted in ambiguous support for the placement of † Kyromyrma , with the genus being recovered as sister to the Lasius genus group ( Figure S5 ), sister to the core Lasiini ( Figures S8 , S 9 ), sister to all Lasiini ( Figure S7 ), or sister to Formicinae exclusive of Myrmelachistini ( Fig. 4 ). Statistical support for these placements was uniformly low.
