Abstract
Triploid female Helophorusbrevipalpis Bedel, 1881 are recorded from two localities in Provence, France. Their karyotypes are analysed using both chromosome morphology and C-banding. Their karyotypes appear to be identical with those of Spanish material recorded by Angus (1992) but show minor differences from Italian triploid material described by Angus, Jia (2020). Data on C-banding in English H.brevipalpis are given and chromosomal variation in H.brevipalpis is discussed.
