The histology and morphology of the reproductive system of females of Rhagoletis conversa (Brèthes) and Rhagoletis nova (Schiner) were studied. These species parasitize wild and cultivated Solanaceae respectively. Adult females of both species were collected in natural populations in the Central Zone of Chile. In order to study the development of ovaries the females collected were sacrificed at different ages. Once obtained, ovaries were preparedfor optical microscopy by using histological and squash standard techniques. Results show that within each one of ovarioles it can be observed follicles arranged in line and showing different stages of maduration. It can be described about 6 follicle stages in the ovarioles studied. Ovaries of both species show a very similar structure. However, females of Rhagoletis nova show an ovipositor wider than R. conversa. The number of ovarioles of R. nova is also higher than in R. conversa.Resumo em Inglês:

Durante o estudo da carcinofauna do litoral baiano, muitos Braquiuros Portunidae foram encontrados. Alguns destes animais foram Callinectes arcuatus Ordway, 1863 que possuia sua distribuição restrita da Califórnia ao Peru e Ilhas Galápagos, no Oceano Pacífico. Esta é a primeira ocorrência desta espécie no Oceano Atlântico e na Costa Brasileira. (Bahia, 12º50'S e 38º50'W).Resumo em Inglês:

Some of these animals were Callinectes arcuatus Ordway, 1863 which has its distribution restricted to the Pacific Ocean, from California to Peru and the Galapagos Islands. This is the first occurrence of this species reported from the Atlantic Ocean and the Brazilian Coast (Bahia, 38º50'Wand 12º50'S).Resumo em Inglês:
