Descriptions of two interesting chironomid pupae collected in Yunnan Province, China (Chironomidae: Chironominae)

Descriptions of two Chironomini pupal types collected in Yunnan Province are given. Among known genera, both types closely resemble that of the North American Hyporhygma Reiss, 1982, but the spine and spinule pattern of the dorsal abdomen does not fit within the current taxonomic boundaries, and represent an endemic component in the Oriental region. A new genus description is expected when associated adults are available.
