Scanning electron microscopy study of the egg of Haemagogus (Haemagogus) capricornii Lutz, 1904 (Diptera: Culicidae).

Morphological details are provided for the dorsal and ventral surfaces of both extremities and the micropylar area of eggs of Haemagogus (Haemagogus) capricornii Lutz, captured in the Biological Reserve of Tinguá, State of Rio de Janeiro, Brazil. The eggs were observed by scanning electron microscopy with a morphometrical analysis of the main structures. The outer chorionic cells on the ventral surface were extremely regular, such as those observed in Hg. equinus and Hg. janthinomys. The tubercles present differences in form, size, and distribution. Filaments to attach to the substrate were observed in this species.
