          Abstract

          Brazil has a high diversity of flies of the genus Drosophila, and part of this richness is represented by the cardini group. We analyzed the fluctuations in the richness and abundance of this group, in environments that had never previously been studied in the northeastern region of Brazil. Among the 28,204 drosophilids sampled, 1,294 belonged to the cardini group and were represented by D. polymorpha, D. cardini, D. neocardini and D. cardinoides. Occurrences of D. neocardini and D. cardinoides were registered for the first time in the Caatinga. In this biome, D. cardini stood out as having the highest abundance, and D. polymorpha was not observed. In the coastal Atlantic Forest, D. cardini was not registered, but D. polymorpha was found in all the localities investigated. Mangrove swamps were the environment with the lowest abundance and richness of the cardini group. The High-altitude Forest presented the highest richness of this group. We suggest that the high abundance of D. polymorpha in the High-altitude Forest and in the coastal Atlantic Forest may be a reflection of the historical relationship between these two environments.

          O Brasil apresenta alta diversidade de moscas do gênero Drosophila sendo parte desta riqueza representada pelo grupo cardini. Nós analisamos as flutuações na riqueza e na abundância deste grupo em ambientes que nunca haviam sido estudados na região Nordeste do Brasil. Entre os 28.204 drosofilídeos amostrados, 1.294 pertenceram ao grupo cardini e foram representados por: D. polymorpha, D. cardini, D. neocardini e D. cardinoides. As ocorrências de D. neocardini e D. cardinoides foram registradas pela primeira vez para a Caatinga. Neste bioma, D. cardini destacou-se como a espécie mais abundante e D. polymorpha não foi observada. Na Floresta Atlântica costeira D. cardini não foi registrada, mas D. polymorpha foi observada em todas as localidades investigadas. Os manguezais foram os ambientes com a menor abundância e riqueza do grupo cardini. Os Brejos de Altitude apresentaram a maior riqueza deste grupo. Nós sugerimos que a alta abundância de D. polymorpha nos Brejos de Altitude e na Floresta Atlântica Costeira pode refletir a relação histórica entre estes dois ambientes.
