Ocyptamus (Pipunculosyrphus) globiceps (Hull)  

The subgenus Pipunculosyrphus is distinguished by: metasternum bare, eye bare, antenna short, vein M1 sinuate, metaespisternum bare, anterior anepimeron pilose, alula reduced about as wide as costal cell, and wing extensively microtrichose.

Hull (1937) created this subgenus for small flies with bright markings and very large head, considerably wider than thorax, abdomen with parallel sides, wing longer than abdomen with alula nearly or completely absent.
