| Outline of Final Research Achievements |
Harvestmen (Arachnida, Opiliones) are suitable animals to understand chromosomal speciation due to their enormous geographical diversity in the number of chromosomes and external morphology even in a single species. In this study, chromosomal data were accumulated for the unstudied areas for Gagrellula ferruginea, the Leiobunum curivipalpe-species group, and Nelima genufusca-species group, and so on. Nature of the several chromosomal hybrid zones have been also analysed. Population genomics surveyed for two thelytokous harvestmen, L. manubriatum and L. globosum revealed that their thelytoky was of facultative, and females of the species mate with two males on average in the wild.
