双翅目（Dipteropeltis）是鳃尾纲的一个单型属，是南美洲特有的。从四个机构获得了12份Dipteropeltis sp.标本和第13份标本的显微照片。对所有样本进行测量并拍摄光学显微照片。并与所有已知的D. hirundo，并将其分为两类，即符合D. hirundo;和那些形态上不同的。将两个样本（每组一个）用木质素粉红色染色，随后准备用于扫描电子显微镜检查。在标本中观察到的差异表明存在一个新物种。因此，Dipteropeltis campanaformis n. sp.，并与D. hirundo。钟形龙脑蕨sp.与D.在头部形状、甲壳叶的长度和形状、小颚的膜组成、小颚的形状、嘴的形状和游泳叶的形状方面，
Dipteropeltis is a monotypic genus of the Branchiura and endemic to South America. Twelve specimens of Dipteropeltis sp. and micrographs of a thirteenth specimen were obtained from four institutions. Measurements and light micrographs were taken of all the specimens. The specimens were compared to all known descriptions of D. hirundo and sorted into two groups, those that conformed to the description of D. hirundo; and those that differed morphologically. Two specimens, one from each group¸ were stained with lignin pink and subsequently prepared for Scanning Electron Microscopy. The differences observed in the specimens indicated that a new species exists. Thus, Dipteropeltis campanaformis n. sp. is described from seven specimens collected from two characiform benthopelagic fish species and compared to D. hirundo. Dipteropeltis campanaformis n. sp. differs from D. hirundo in the head shape, the length and shape of the carapace lobes, the membrane composition of the maxillules, the shape of the maxillae, the shape of the mouth, and the shape of the natatory lobes.
