title: The blattodeas.s. (Insecta, dictyoptera) of the Guiana shield.
abstract: Here we provide a checklist of cockroach species known from areas within the Guiana Shield based on literature records and new field collection. We give records of sixteen species collected in Guyana, eight of which are new records for Guyana and one of which is a new generic record for the entire Guiana Shield. We also provide a description for a geographically disparate species of Calhypnorna Stal, and the new species Xestoblattaberenbaumae. The complete checklist contains 234 species of Blattodeas.s. currently known in the shield. This checklist shows particularly low richness in Guianan Venezuela, Roraima and Amapa Brazil, but this is likely an artifact due to under-sampling. Indeed, based on previously published data and current fieldwork, we believe that most regions of the Guiana Shield are under-sampled for cockroaches. Despite this, French Guiana (151 spp.) and Suriname (136 spp.) rank as the second and sixth most species dense faunas of cockroaches in the neotropics.
