ABSTRACT
The butterfly subtribe Coenonymphina (Nymphalidae Satyrinae) comprises four main clades found, respectively, in (1) the Solomon Islands, (2) Australasia, (3) NW South America and (4) Laurasia, with a phylogeny 1 (2 (3 + 4)). In assessing biogeographic evolution in the group we rejected the conversion of fossil-calibrated clade ages to likely maximum clade ages by the imposition of arbitrary priors. Instead, we used biogeographic-tectonic calibration, with fossil-calibrated ages accepted as minima. Previous studies have used this approach to date single nodes (phylogenetic-biogeographic breaks) in a group, but we extended the methodology to date multiple nodes. Within the Coenonymphina as a whole, 14 nodes coincide spatially with ten major tectonic events. In addition, the phylogenetic sequence of these nodes conforms to the chronological sequence of the tectonic events, consistent with a vicariance origin of the clades. Dating of the spatially coincident tectonic features provides a timescale for the vicariance events. The tectonic events are pre-drift intracontinental rifting between India and Australia (150 Ma); seafloor spreading at the margins of the growing Pacific plate, and between North and South America (140 Ma); magmatism flare-up along the SW Pacific Whitsunday Volcanic Province-Median Batholith (130 Ma); a change from extension in the Clarence basin, eastern Australia, to uplift of the Great Dividing Range (114 Ma); Pamir Mountains uplift, foreland basin dynamics and high eustatic sea-levels leading to marine transgression of the proto-Paratethys Ocean eastward to Central Asia and Xinjiang (100 Ma); predrift rifting and seafloor spreading west of New Caledonia (100-50 Ma); sinistral strike-slip displacement along the proto-Alpine fault, New Zealand (100-80 Ma); thrust faulting in the Longmen Shan and foreland basin dynamics around the Sichuan Basin (85 Ma); pre-drift rifting in the Coral Sea basin (85 Ma); and dextral displacement on the Alpine fault (20 Ma).
