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 National policy might be up to speed, but international legislation regarding trading of wildlife, such as CITES, are outdated.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.

重新发现的风险：本地特有的智利锹形甲虫Sclerostomulus nitidus（鞘翅目：Lucanidae）的种群快速下降表明贸易是一种威胁

1. 重新发现应该是庆祝活动，但是在公开发布时必须小心。以前被认为已灭绝的可收集物种通常很少见，每收集一个个体直至灭绝，都会不断增加商业价值。
2. 最近重新发现的saproxylic甲虫nitcletus nitidus（贝尼什，1955年）就是这种情况，2012年重新发现，其唯一已知的全球人口居住在智利的塞罗波基的唯一一座山上。
3. 我们每年采样146个死木，发现在5年内（2013-2018年），每根针状巩膜菌的丰度下降了93％，并估计到2030年发现至少一个个体的可能性很可能接近零。线性趋势。
4. 由于地理范围受到限制，nitcletus nitidus被智利法律列为极度濒危物种，但是由于我们观察到人口不断减少的趋势以及发现一个个体的预计概率，因此我们建议新的IUCN红色名录。
5. 在野外时，我们目睹了进行中的搜集过程，因此也提供了目前存在的核盘菌在线交易的证据。因此，为了补充对链球菌生态学的研究，我们建议着重于统一有关贸易或被贩运物种的国家和国际政策。
6. 国家政策可能会加快步伐，但是有关野生动植物贸易的国际立法（例如CITES）已经过时。使国家和国际政策相互兼容，将为与快递服务进行认真讨论的可能性提供可能性，以进行透明度和监测程序，以制止最近重新发现的物种最容易受到束缚的不受限制的贸易或贩运。
