Idgia huegeli (Redtenbacher, 1868)

Prionocerus hügeli Redtenbacher, 1868: 110 . Idgia Hügeli: Pic, 1926: 7.

This species was described as Prionocerus and later transferred to Idgia (Pic 1926), but probably without examination of the type. The holotype is deposited at NHMW (labelled "Hügel" and " hügeli Rdt, China ") and could be examined. Apart from this, only a single specimen without locality at NHML seems to be known. It is a very unusual prionocerid of large size, shining, entirely metallic blue coloration, only very slightly serrate antennae, very elongate, rostriform head, and a deep, U-shaped incision on its subapical sternite. At least by its habitus and size it is most similar to Idgia oculata Redtenbacher, 1868, I. viridivittata Champion, 1919 and I. maculatithorax Pic, 1919 . In any case it cannot be placed in Prionocerus .
