Abstract

Tergissima and Femniterga, new genera, are described from hitherto seldom sampled localities of 500- 1700 m. altitude in Salta, Jujuy and Tucuman provinces, Argentina. The new genera are allied to New World Calycopis and Neotropical Calystryma, but differ from the generic characters of these in having extreme terminoventrad development of the incised posterior cavity of the eighth abdominal tergite (Tergissima males, Femniterga, males and females), distinctive genitalic characters and forewing markings on males suggestive of secondary sexual brands. Morphology of the four genera is compared in detail. Four new species are described: T. mosconiensis, T. macphersoni, F. notacastanea and F. judae, three of which are also distributed northward into eastern Bolivia.
