Paravelia basalis (Spinola, 1837)

Fig. 53A, D

Diagnosis. Body length 6.2–6.5 mm; thorax and abdomen dark-brown to black; pronotal humeral angle never with spinose projection; forewings without bubble-like structures; basal maculae of forewings starting from humeral angle, distinctly yellow; apical macula of forewings, when present, narrow and elongated; hind femur without spines; venter of abdomen not covered by punctations; male abdominal sternum VII with pair of large projections ( Rodrigues & Moreira 2022).

Comments. This species seems to live preferably on moist terrestrial environments, rather than on streams or rivers. Although much field work has been carried out in localities where it is expected to occur, it was never collected by the present authors on the surface or margins of water bodies. The specimen from Nova Iguaçu below was obtained while it was walking in the middle of a trail composed mainly of sand and grass, parallel to a river, but not contiguous with it.
