“…Interestingly, S. nitidus is not the only beetle whose whole species distribution is restricted to this mountain. Cerro Poqui is also inhabited by other endemic insects, such as Callyntra hibrida (Zúñiga-Reinoso & Arcos-Cid, 2013), Protoanthicus poqui (Guerrero & Diéguez, 2018) and Licinoma poqui (Guerrero & Vidal, 2019). Multiple species from this area are currently threatened by habitat loss and potentially by the insect trade due to opportunistic overexploitation (Branch et al, 2013), and those yet to be assessed might even be critically endangered, since they comply with geographic range thresholds of 10 km 2 , the estimated surface area of Cerro Poquiincreasing its importance as a privately owned protected area (Table 1).…”

“…We only marked the sternites to reduce the chance of inadvertently helping collectors find individuals. In addition, due to S. nitidus being brachypterous and to complement the sampling design, we used dry pitfall traps (200 ml of empty volume), spaced every 10 m and distributed randomly along each sampling Guerrero and Diéguez (2018) plot (n = 22 per plot). We employed dry pitfall traps because this species is critically endangered by Chilean Ministry of Environment (DS 38/2015;MMA, 2019).…”

1. Rediscovery should be a celebratory event, but caution must be taken when making it public. Collectible species previously thought to be extinct are generally rare, which continuously increases the commercial value every time an individual is collected until extinction. 2. This is the case with the recently rediscovered saproxylic beetle Sclerostomulus nitidus (Benesh, 1955), rediscovered in 2012, whose only known global population inhabits one sole mountain, Cerro Poqui, Chile. 3. We sampled 146 dead logs per year and found that abundance per log of Sclerostomulus nitidus decreased by 93% in a 5-year period (2013-2018) and estimated the probability of finding at least one individual is likely to approach zero by 2030 following a linear trend. 4. Sclerostomulus nitidus is listed as Critically Endangered by Chilean Law due to restricted geographic range, but we propose a need for new IUCN Red Listing resulting from our observations of ongoing population size reduction and the projected probabilities of finding an individual. 5. While in the field, we witnessed ongoing collection and so present evidence of online trade of Sclerostomulus nitidus. Therefore, to complement the study of the ecology of S. nitidus, we suggest a focus on unifying national and international policies regarding traded or trafficked species. 6. National policy might be up to speed, but international legislation regarding trading of wildlife, such as CITES, are outdated. Making national and international policy compatible would open possibilities for serious discussions with courier services regarding transparency and monitoring processes used to stop unfettered trading or trafficking to which recently rediscovered species are most vulnerable.

“…Posterior a la validación y revisión del género, el análisis filogenético basado en morfología daba cuenta de 17 especies para este grupo (Flores, 2000;Flores y Vidal, 2000a, b). Trabajos posteriores han descrito 8 especies nuevas (Aceituno y Guerrero, 2014;Guerrero y Vidal, 2020;Zúñiga-Reinoso, 2016;Zúñiga-Reinoso y Cid-Arcos, 2013Zúñiga-Reinoso et al, 2017, elevando a 24 el total. Sin embargo, el reciente análisis filogenético molecular y de delimitación de especies, sugirió al menos 5 especies crípticas, de las cuales 1 fue descrita recientemente .…”
