BRAZIL - Parque Estadual do Jaragua , Sao Paulo State ( 23°27'S , 46°45'W ), Nova Friburgo, Rio de janeiro State, Rio Boa Vista; Bocaina de Minas, Minas Gerais State ( 22°19'S , 44°34'W ); Serra do Japi, Jundiai , Sao Paulo State ( 23°14'30"S , 46°57'16"W ); Serra da Bodoquena, Mato Grosso do Sul State ( 20°41'49"S , 56°52'54"W ). Elevation. 700-1200 m a.s.l. Habitats. Litter near the water surface of a small shallow stream. Known stages. L, P, F, M. References. Wiedenbrug and Trivinho-Strixino (2011) ; Wiedenbrug et al. (2012) . Remarks. C. septadentata was found on marginal rocks of small streams and on rocky seepages (large exposed rock in the middle of the forest), from 1045-1580 m a.s.l., extending slightly the altitudinal range of this species. Environmental characterization: Water temperature 15-17 °C; dissolved oxygen 8.6-10.2 mg.l-1; pH 5; moderate to fast flowing; vegetal canopy reduced or absent (less than 30% covered). The species was found in PARNASO (Rio de Janeiro State) and PESM ( Sao Paulo State). Low altitudinal specificity (IndVal: 0.09; p = 0.88).
