Abstract: 

A number of new records of Chionea araneoides Dalman, 1816 from the county of Nordland (NSI and NSY) are presented. The total knowledge today indicates a distribution over the whole country. A single individual of Chionea crassipes Boheman, 1846 collected in Rana (NSI) contradicts an earlier assumption of a bicentric distribution in Norway. While C. crassipes has been found to be more common than C. araneoides in Finnmark, the opposite is the case south of Troms. In order to find out at which latitude the dominance between the two species shifts, more records of Chionea Dalman, 1816 from Troms are needed. At Vågå in northern Oppland County (ON), C. araneoides has been collected repeatedly above the tree line, up to 1465m above sea level, which is a new Norwegian altitude record. Habitat choice at high altitudes is commented on.
