Many flesh flies of the subfamily Sarcophaginae are very competitive carrion visitors and breeders, and several are synanthropic species of medical and forensic importance. The knowledge of these taxa is still limited, which is more noticeable in sub-sampled ecosystems such as the tropical dry forests of Colombia. Four new species, Blaesoxipha (Gigantotheca) wajiira sp. nov., Lepidodexia deborarangoa sp. nov., Oxysarcodexia luriza sp. nov. and Udamopyga iku sp. nov., are described from tropical dry forests in the Colombian departments of Atlántico, Bolívar, Cesar and La Guajira, all collected using Van Someren-Rydon traps baited separately with fermented fruit, decomposing fish and human feces. The species B. (G.) wajiira sp. nov. is probably synanthropic, while the remaining three new species avoid habitats in and around built-up areas. A phylogenetic parsimony analysis based on 222 morphological characters across 121 taxa of flesh flies recovers each new species nested within their respective genus. The subgeneric affiliation of L. deborarangoa sp. nov. within the large and diverse genus Lepidodexia (sensu lato) is inconclusive, and potential issues of relying solely on external morphological characters for generic and subgeneric classifications are highlighted. The species Lepidodexia (Notochaeta) woodi (Lopes), Oxyvinia wicharti (Lopes) and Sarcofahrtiopsis spinetta Mulieri & Dufek are new records for Colombia. COI sequence data are provided for U. iku sp. nov., L. (N.) woodi and O. wicharti.
许多肉蝇亚科的肉蝇都是非常有竞争力的腐肉访客和繁殖者，其中有几种是具有医学和法医学重要性的共生种。这些类群的知识仍然有限，在像哥伦比亚热带干旱森林这样的抽样不足的生态系统中更为明显。四种新物种，Blaesoxipha (Gigantotheca) wajiira sp. nov.、Lepidodexia deborarangoa sp. nov.、Oxysarcodexia luriza sp. nov. 和 Udamopyga iku sp. nov.，是从哥伦比亚的大西洋省、玻利瓦尔省、塞萨尔省和拉瓜希拉省的热带干旱森林中描述的，所有这些物种都是使用 Van Someren-Rydon 陷阱收集的，陷阱分别用发酵水果、分解的鱼和人类粪便诱饵。B. (G.) wajiira sp. nov. 可能是共生种，而其余三种新种则避免在建成区及其周围的栖息地出现。基于 121 种肉蝇的 222 个形态特征的系统发育简约分析恢复了每个新物种嵌套在其各自属内。Lepidodexia (sensu lato) 属内的 L. deborarangoa sp. nov. 的亚属归属尚不清楚，并且仅依靠外部形态特征进行属和亚属分类的潜在问题也得到了强调。Lepidodexia (Notochaeta) woodi (Lopes)、Oxyvinia wicharti (Lopes) 和 Sarcofahrtiopsis spinetta Mulieri & Dufek 是哥伦比亚的新记录种。为 U. iku sp. nov.、L. (N.) woodi 和 O. wicharti 提供了 COI 序列数据。
