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.

石棺亚科的许多果蝇都是极富竞争性的腐肉游客和繁殖者，其中有几种是具有医学和法医学意义的同生物种。这些分类单元的知识仍然有限，这在子抽样生态系统（例如哥伦比亚的热带干旱森林）中更为明显。四个新种Blaesoxipha（Gigantotheca）wajiira sp.。十一月，Lepidodexia deborarangoa sp.。十一月，Oxysarcodexia luriza sp。十一月 和Udamopyga ikusp。nov。是从哥伦比亚Atlántico，Bolívar，Cesar和La Guajira部门的热带干旱森林中描述的，它们都是使用Van Someren-Rydon诱捕器收集的，诱饵分别用诱饵发酵的水果诱捕，分解鱼和人的粪便。该物种乙。（G.）wajiira sp。十一月 可能是合人类的，而其余三个新物种避开了建成区及其周围地区的栖息地。基于121个果蝇类群的222个形态特征的系统进化简约分析，可回收嵌套在其各自属中的每个新物种。L. deborarangoa sp。的亚属隶属关系。十一月 在大型多样的鳞翅目（Sendus lato））尚无定论，并着重指出了仅依靠外部形态特征进行通用和亚通用分类的潜在问题。该物种Lepidodexia（Notochaeta）woodi（洛佩斯），Oxyvinia wicharti（洛佩斯）和Sarcofahrtiopsis斯皮内塔Mulieri＆杜费克是哥伦比亚新记录。为U. iku sp。提供了COI序列数据。nov。，L。（N.）woodi和O. wicharti。
