Mean intraspecific genetic divergence for the 58 evaluated morphologically distinct species (i.e. members of species complexes not included) was 0.76%. The maximum intraspecific divergence value (3.84%, mean = 1.03%) was observed in Simulium (Simulium) rostratum, followed by Simulium (Nevermannia) silvestre(3.51%, mean = 1.45%) and Prosimulium travisi (3.36%, mean = 1.76%; Table 2). Higher levels of divergence were found among members of cytologically defined
sibling complexes: Helodon (Helodon) onychodactyluscomplex (max. 4.91%), Stegopterna mutatacomplex (max. 5.47%),
Simulium (Simulium) arcticumcomplex (max. 6.5%), Simulium (Simulium)tuberosumcomplex (max. 5.44%) and Simulium
(Simulium)venustumcomplex (max. 5.31%; Table 2). Putative species complexes also exhibited higher levels of intraspecific divergence as in Simulium (Nevermannia)craigi (max. 4.93%), Simulium(Nevermannia) quebecense(max.
5.79%) and Simulium (Simulium)murmanum(max. 4.58%). Along similar lines, specimens identified as Simulium (Hellichiella) nebulosumalso exhibit a high intraspecific genetic divergence (max. 4.58%; Table 1); however, it is possible that our sample also included members of Simulium (Hellichiella)minus
