Natalis Laporte (1836)

Type species: Natalis laplacei Laporte (1836)

Diagnosis: According to the current analysis, the genus Natalis is composed of only two species, N. laplacei from Chile and N. wagneri from Argentina. The synapomorphies that characterize this taxon are the special modification of the male tegmen mentioned above and the dark brown with a yellowish transverse band of elytra. N. wagneri is particularly apomorphic because of the shortening of the tegmen ( Fig. 6 ), reversal of the weakly sclerotized zones laterally behind the base of the parameres and in the parameral apices ( Figs. 5 and 6 ), the bending of the apodeme ( Fig. 6 ), the dorsal division of the tegmen, the complex sclerotization of the median lobe of the aedeagus ( Fig. 12 ), and the shortening of the bursa copulatrix ( Fig. 15 ). Natalis laplacei is distinguished by a pronounced frontal pit. Descriptions of these species were made by Solervicens (1973).
