First descriptions of two new amber species of Cyphomyrmex from Mexico and the Dominican Republic (Hymenoptera: Formididae).

Abstract: Zwei neue fossile Arten von Cyphomyrmex aus Bernstein, jede durch ein einzelnes Exemplar belegt, werden beschrieben. C. maya basiert auf einer einzelnen Arbeiterin aus Mexikanischem Bernstein. C. taino wird nach einer geflügelten Gyne aus Dominikanischem Bernstein beschrieben. C. maya und C. taino gehören zur rimosus-Gruppe sensu Kempf (1964) und innerhalb dieser zur foxi-Subgruppe sensu Snelling & Longino (1992). Von den beiden bekannten jamaikanischen Vertretern der foxi-Subgruppe ähnelt C. maya vor all… Show more

“…We used the software packages BEAST [59] in conjunction with the alignment to calculate relative branching time estimates for the species shared between the alignment and the supertree following previous studies [46] under a strict molecular clock [60]. Three Attini fossils were used as calibration points at nodes 11 [61], 50 [62] and 54 [63] and a non-Attini fossil (Pheidole) [64] was used to date node 1 (see the electronic supplementary material, figure S2), allowing dates to be calculated from relative branch lengths. The perl script chronographer.pl [65] was used to infer missing node ages based on a pure-birth model resulting in a supertree topology with branching time estimates following [46].…”
