Resumen
M. paulistus is common in northern Argentina, being also a pest of olives in Mendoza. Crouzel (1973) said that sometimes it occurs on citrus. Several parasitoids attacking it have been recorded (De Santis, 1967 and 1973). The list is enlarged now with the aphelinids Aphytis costalimai (Gomes), Aphytis sp. and Prospaltella ectophaga Silvestri, the encyrtid Zaomma lambinus (Walker) and the signiphorids Signiphora sp. and S. desantisi (De Santis). The new status of S. desantisi is established based principally on its biology, this species being a primary gregarious ectoparasitoid of adult females scales of M. paulistus, Some field observations on the other species obtained from M. paulistus are mentioned.

Resumen
Morphometric data show that Batrachophrynus macrostomus Peters differs widely from 24 species and subspecies of Telmatobius so that even if it was not toothless, it would deserve its generic status. B. brachydactylus Peters, while considerably more similar to Telmatobius by its appearence, is also morphometrically distinct and often in a way which is opposite to that of macrostomus. Therefore, it seems to constitute an independent lineage and deserve also a generic autonomy which is proposed under the name of Lynchophrys. The validity of Atelognathus Lynch, based on Batrachophrynus patagonicus Gallard is morphometrically confirmed.

Resumen
The genus Cheilopsis is described with a single inca species on the basis of a female specimen. Their tribal position remains uncertain, being found between the genera Cerapterocerini (morphology of the head, jaws and antennae) and the genera Cheiloncurini (morphology of the thorax, wings and abdomen).

Resumen
Two new species belonging to group three of the genus Cardiorhinus are described: hayekae and maculatus, both from Venezuela, and ten new species belonging to group four: chilensis from Chile, coralinus from Brasil, costae from Brasil and Argentina, elegans from Brasil, luisae from Paraguay, parabicolor from Brasil, parapullatus from Paraguay and Brasil, porteri from Argentina, unicolor from Chile, and ypirangus from Brasil. Descriptive notes of the known species and keys are also given. The species seen by the author are illustrated and the importance of the length of the 2nd, 3rd, and 4th articles of the antennae is pointed out as a help for identification.
