Abstract

edit
  • Six species of psychopsoid neuropterans are recorded from the southeastern Queensland Late Triassic Blackstone Formation at Denmark Hill and Dinmore, the Late Triassic Mount Crosby Formation at Mount Crosby, and the early Middle Triassic Gayndah Formation at Gayndah. Triassopsychops superbus Tillyard (previously known from Denmark Hill, newly recorded from Dinmore) has a suite of apomorphies confirming its earlier placement in Psychopsidae. Additional material of Osmylopsychops spillerae Tillyard (type species of the family Osmylopsychopidae) (previously known from Denmark Hill and Mount Crosby, newly recorded from Dinmore) confirms the presence of a recurrent humeral vein and demonstrates its high degree of intra-specific variation in size and venation. Petropsychops superbus Riek (previously known from Denmark Hill, newly recorded from Mount Crosby), with M and Rs uniquely structured basally, is retained in Osmylopsychopidae, although its strongly pectinate M is similar to some species of the Mesozoic psychopsoid family Kalligrammatidae. Archepsychops triassicus Tillyard (Denmark Hill), possibly conspecific with O. spillerae, is known only from its fragmentary holotype and is retained for convenience in Osmylopsychopidae. Protopsychopsis venosa Tillyard (Denmark Hill) is known only from its holotype, which is too fragmentary to be considered any more than Neuroptera incertae sedis. The sixth species, Gayndahpsychops carsburgi gen. et sp. n., from the early Middle Triassic of Gayndah, is a small osmylopsychopid with CuA extensively pectinate.
