Abstract

The male meiotic karyotypic formulae of Dendroctonus parallelocollis Chapuis and D. rhizophagis Thomas & Bright are 13 AA + Xyp. These karyotypes are similar to those from D. valens LeConte (13 AA + Xyp) and D. terebrans Olivier (12 AA + Xyp), a situation that confirms the taxonomic grouping of these species by morphological characteristics and their status as closely related species. The chromosome numbers and the sexual systems of populations of Dendroctonus adjunctus LeConte, D. approximate Dietz, D. frontalis Zimmermann, D. mexicanus Hopkins, and D. valens agree with what has been published for these species. No geographic variation in the karyotypes, supernumerary chromosomes, or irregular associations were observed in the species examined.
