RESUMO
Mepraia spinolai, M. gajardoi and M. parapatrica occur in distinct regions in Chile. The females of the three species are micropterous. The males of M. gajardoi are brachypterous, those of M. parapatrica can be brachypterous or macropterous and those of M. spinolai can be micropterous, brachypterous or macropterous. Morphological studies were carried out by scanning electron microscopy of female specimens collected in the wild. Head, thorax and abdomen characters of the three species there were not previously studied by SEM allowed a clear distinction amongst the three species.

The morphology of the third-instar larva of Anastrepha leptozona Hendel is characterized using optical and scanning electron microscopy. The antennomaxillary complex, oral ridges, labium, stomal sensory organ, cephalopharyngeal skeleton, anterior and posterior spiracles and caudal segment are described and illustrated. Mature larvae of A. leptozona present a 'ventral sclerite' below the pharyngeal sclerite which is characterized for the first time in Anastrepha species.

A morfologia da larva do terceiro ínstar de Anastrepha leptozona Hendel é descrita. São analisados, em microscopia de luz e de varredura, o complexo antenomaxilar, as margens da abertura oral, o bordo, o órgão oral, o esqueleto cefalofaríngeo, os espiráculos anterior e posterior e o segmento caudal. As larvas do terceiro ínstar de A. leptozona têm um "esclerito ventral" abaixo do esclerito faríngeo, o qual é caracterizado pela primeira vez em espécies de Anastrepha.
