Carrion flies in the taxonomic family Sarcophagidae are often recovered from a human corpse. However, because such specimens are difficult to identify, the forensic literature on this taxon is quite limited compared with that of the commonly employed Calliphoridae. Faced with a sarcophagid larva that could not be identified microscopically from a death investigation in the state of Idaho, we generated cytochrome oxidase one DNA sequence data from the specimen. Comparison to a reference data set of forensically significant sarcophagids from Canada and the U.S.A. confirmed that this was the first discovery of Blaesoxipha plinthopyga in a human corpse in the U.S.A. and the first record of this species in Idaho. Because B. plinthopyga occurs from the Northern U.S.A. to the Neotropics, it is potentially useful for estimating time since death at many locations.
麻蝇科的腐肉蝇经常在人类尸体上被发现。然而,由于这类标本难以鉴定,与常用的丽蝇科相比,关于这个分类群的法医文献相当有限。面对在爱达荷州的一次死亡调查中无法通过显微镜鉴定的麻蝇幼虫,我们从该标本中生成了细胞色素氧化酶亚基I的DNA序列数据。与来自加拿大和美国的具有法医意义的麻蝇参考数据集进行比较后证实,这是在美国人类尸体中首次发现的扁臀拟刺腹蝇,也是该物种在爱达荷州的首次记录。由于扁臀拟刺腹蝇分布于美国北部至新热带地区,它在许多地点对于估计死亡时间可能是有用的。
