Remarks.

H. caissara was found on marginal rocks of a small stream, at 200 m a.s.l. This slightly extended the altitudinal records of the species. Environmental characterization: Water temperature 21 °C; dissolved oxygen 7.9 mg.l-1; pH 5.5; fast flowing; sparse vegetal canopy (less than 30% covered). The species was found in PESM ( São Paulo State). Median altitudinal specificity (IndVal: 0.33; p = 0.13).

Unknown species. Hudsonimyia sp.1. Locality: PESM. Altitudinal record: 1080 m a.s.l. Low altitudinal specificity (IndVal: 0.17; p = 0.85).
