Zigópteros de Phytotelmata das imediaçõs de Manaus, com ênfase na Biologia Ninfal e a descrição de uma espécie nova (Odonata: Coenagrionidae; Pseudostigmatidae)

Abstract

In this dissertation, three species of zygbpterans that live in phytotelmata of Manaus and surroundings are studied: The Coenagrionidae Leptagrion beebeanum Calvert, 1948 and Leptagrion sp. no. and the Pseudostigmatidae Microstigma maculatum Selys, 1860. The naiads of Leptagrion beebeanum were found in Bromeliaceae epiphytes and terricolas, those of Leptagrion sp. no. in buritize trees (Mauritia flexuosa L.) and those of Microstigma maculatum in fallen bracts of bacabeira (Oenocarpus bacaba Mart.). A total of 144 specimens were studied (14 imagos, 90 naiads and 40 exuviae). The number of nymphal stages of Leptagrion sp. no. based on chin biometrics. The following are described: the imgo of Leptagrion sp. n., its last instar exuvia and its estimated nymphal stages; the penis of Leptagrion beebeanum and its last-stage exCrvia; the last six nymphal stages of Microstigma maculatum. The naiads of Leptagrion sp. no. and Microstigma maculatum were tested for par%metaxos involved in their status as dendrolimnetobionts and the results discussed.
