Second species of Langlieria (Tristichopteridae, Sarcopterygii) from the Upper Devonian Catskill Formation of Pennsylvania, U.S.A., and a new phylogenetic consideration of Tristichopteridae
ABSTRACT. A new species of Langlieria is described from the Upper Devonian (Frasnian) Irish Valley Member of the Catskill Formation. The type material was collected from a road cut exposure on the north side of the westbound lanes of Pennsylvania Route 322 west of Port Matilda, Centre County, Pennsylvania, U.S.A. The new species of Langlieria, the second from the Catskill Formation, is represented by high quality cranial material including parietal and postparietal shields, cheek, principal gular, and lower jaw; fin material; and body scales. The new species is the fourth tristichopterid to be described from the Catskill Formation (after Hyneria lindae, Langlieria radiatus, and Eusthenodon bourdoni) and the first from the Irish Valley Member. It is also the first species of Langlieria with a known record in the Frasnian. Sedimentological and stratigraphic data suggest that the discovery site represents a distal, tide-dominated location within the Catskill Delta system with a greater marine influence than has been reconstructed for the previously described Catskill Formation tristichopterids. A new phylogenetic analysis of Tristichopteridae is presented that is the first to include the new species of Langlieria described here and E. bourdoni from the Cogan House Exit Ramp locality (Famennian, Duncannon Member) along U.S. Route 15/Interstate 99. The 50% majority-rule consensus tree from the analysis supports a highly-nested clade of tristichopterids that includes all of the considered species from the Famennian, with the exception of Heddleichthys dalgleisiensis, and additionally includes the Frasnian Langlieria species that is described here.
