Citizen science expanding knowledge: a new record of the lizard Heterodactylus imbricatus (Squamata, Gymnophthalmidae) in south-eastern Brazil

Abstract

Through citizen science projects, like Projeto Bromélias, community members contribute valuable data on species diversity, notably those with low detectability like the Heterodactylus imbricatus lizard. A recent observation in the State of Espírito Santo (south-eastern Brazil), amidst coffee and eucalyptus crops, highlights the utility of widespread technology use in tracking and documenting wildlife. Such initiatives are especially beneficial for mapping the distribution of rare, endemic or endangered reptiles. Therefore, we advocate for more citizen science initiatives near protected areas, involving local communities. We provide a new record for the species Heterodactylus imbricatus, a microteiid lizard of low detectability from the Atlantic Forest of south-eastern Brazil. Heterodactylus imbricatus (Rio de Janeiro Teiid) was recorded near the protected area "Reserva Biológica Augusto Ruschi" by a citizen volunteer who contributes herpetofauna records to the Bromelias Project (https://www.inaturalist.org/projects/projeto-bromelias). Heterodactylus imbricatus is a very poorly-known species in the localities where it occurs, probably due to its fossorial habit, genera's restricted occurrence range, habitat specificity and the absence of proper survey methods fitted to fossorial species, such as the utilisation of pitfall traps. By publishing the records of volunteer citizens, we hope that more people will contribute to increase the knowledge of biodiversity in the mountainous region of Espírito Santo State and expand our collective knowledge.
