Abstract

New fossil insect specimens from two new localities in Germany, namely Sperbersbach and Cabarz (Goldlauter Formation; early Permian), belonging to the Grylloblattida, are described. Abundant material is assigned to Pictoborella clara n. gen. n. sp., regarded as closely related to Pictoborella germanica (Prokop et al., 2012) n. comb., from the Saar-Nahe Basin (Germany; early Permian). Liomopterum fuscatum n. sp., represented by fewer specimens, is delimited based on previously published and new data on various Liomopterum spp. Two other Liomopteridae, Uralioma thuringiensis n. sp. and Liomopterites sperbersbachensis n. sp., each known from a single forewing, are also described. Finally, Cabarzopterum magnificus n. gen. n. sp., with unclear familial affinities, is described based on three forewings. The assemblages of grylloblattidan insects at Sperbersbach and Cabarz are generally similar, with differences probably related to different depositional environments and local paleoclimatic conditions.

Methods

Each RTI file was computed from 42 original photographs taken using a ca. 30-cm diameter automated light dome driving a digital camera Canon EOS 5D Mark III coupled to a Canon MP-E 65 mm macro lens. Original photographs were optimized using Adobe Photoshop CS6 prior to RTI-processing, itself achieved using the RTIbuilder software (Cultural Heritage Imaging).

Usage Notes

The software RTIviewer is needed to open the contained files.
