A New Bolivian Trachysphyrus of the Imperialis Group (Hymenoptera, Ichneumonidae)


Entomologically, Bolivia is perhaps the least known part of Latin America. In 1967, when I published a monograph of the nearly 100 predominantly Andean and southern South American species of Trachysphyrus, I could include onty two records from that country, although adjacent Perú, Chile, and Argentina were each found to be major centers of abundance and diversity for Trachysphyrus. In March of 1968, however, when I was able to spend a week collecting near La Paz, I discovered an abundant and conspicuous new Trachysphyrus belonging to the group of T. imperialis Haliday, as defined in my earlier study (Porter 1967, p. 275).
