There are 160 valid species of Culicoides Latreille described from the Nearctic Region, but many are unknown as immatures or, although partially described, cannot be readily identified. We provide pupal diagnoses, descriptions, and a key to all seven known species of Culicoides subgenus Monoculicoides Khalaf occurring in the Nearctic biogeographic region. A diagnosis of several characters unique to this subgenus is provided to allow for the recognition of the included species from those of other subgeneric groupings. Microphotography of important morphological characters for both the key and descriptions are provided. This study highlights the usefulness of examining the pupae of Culicoides as a tool for species identification. The pupae of Culicoides grandensis Grogan Phillips, C. occidentalis Wirth Jones, and C. shemanchuki Grogan Lysyk are newly described and those of C. riethi Kieffer, C. stigma (Meigen), and C. variipennis Wirth Jones are redescribed in detail. The seventh species, C. sonorensis, was fully described recently.
从新北区已描述的拉氏库蠓有160个有效物种，但许多物种的幼虫阶段尚不为人所知，或者虽有部分描述，但难以轻易鉴定。我们提供了蛹的诊断、描述以及新北区生物地理区域内已知的所有七种单眼库蠓亚属库蠓的检索表。给出了该亚属特有的几个特征的诊断，以便从其他亚属分组的物种中识别出所包含的物种。提供了用于检索表和描述的重要形态特征的显微照片。本研究强调了检查库蠓蛹作为物种鉴定工具的有用性。新描述了格兰德库蠓、西方库蠓和舍曼丘基库蠓的蛹，并详细重新描述了里氏库蠓、柱头库蠓和变异翅库蠓的蛹。第七个物种索诺拉库蠓最近已有完整描述。
