The taxonomic identity of two species of sand flies, Psathyromyia pradobarrientosi (Le Pont, Matias, Martinez & Dujardin, 2004) and Psathyromyia runoides (Fairchild & Hertig, 1953) (Diptera, Psychodidae), was evaluated morphologically and molecularly based upon specimens collected in Brazilian states. The morphological component compared collected specimens with paratypes of Pa. runoides and Pa. pradobarrientosi and their descriptions. Phylogenetic analysis of coI sequences of Pa. pradobarrientosi showed a well-supported group distinct from Pa. runoides. Morphologically, Psathyromyia runoides and Pa. pradobarrientosi males are distinguished by characteristics of the aedeagal ducts and parameral sheath in the genitalia; females are distinguished by the number and shape of the teeth in the cibarium and by the shape of the spermathecae. Given the morphological similarity between the males and the absence of the description of the female of Pa. pradobarrientosi, it is possible that specimens previously identified as Pa. runoides in Brazil are in fact Pa. pradobarrientosi.
两种沙蝇，Psathyromyia pradobarrientosi（Le Pont、Matias、Martinez 和 Dujardin，2004）和 Psathyromyia runoides（Fairchild 和 Hertig，1953）（双翅目，Psychodidae）的分类学身份，根据在巴西各州收集的标本进行了形态和分子评估。形态学部分将收集的标本与 Pa. runoides 和 Pa. pradobarrientosi 的副型和描述进行了比较。Pa. pradobarrientosi 的 coI 序列的系统发育分析显示出一个与 Pa. runoides 明显不同的支持良好的群体。形态上，Psathyromyia runoides 和 Pa. pradobarrientosi 雄虫的生殖器中精囊管和副棘鞘的特征不同；雌虫则通过颊囊中的牙齿数量和形状以及受精囊的形状来区分。鉴于雄性之间的形态相似性以及 Pa. pradobarrientosi 雌性的描述缺失，巴西以前被鉴定为 Pa. runoides 的标本实际上可能是 Pa. pradobarrientosi。
