Indian records. Jammu & Kashmir (Himalayas)— Raina & Vass (1993); Sikkim — Venkataraman et al. (1999); General record— Raghunathan & Suresh Kumar (2003).
Remarks. Valid species described from Kaliningrad Area, European Russia (Zaddach 1855). Indian populations must be studied in detail for confirmation of their status.
Distribution. Keeping in mind that in the Americas the genus is represented by a series of species (Rowe et al. 2007), we can assume that H. gibberum s. lat. in Eurasia is probably also complex of cryptic species with unknown areas of distribution. Palaearctic populations need to be revised.
