Distribution and bionomics. Culex phyllados  was found in four different municipalities (Novo Airão, Japurá, São Gabriel da Cachoeira and Nhamunda) in the state of Amazonas, Brazil. This species was collected along rivers in both primary and secondary forest using UV light traps (1800 –0600 h), Shannon traps (1800– 2100 h) and CDC traps with either incandescent or UV light sources (1800 –0600 h). Nothing is known about the bionomics of this species.

Etymology. The name phyllados, Greek  for ‘leafy’, was chosen to reflect the presence of 2–5 foliform setae on the tergomesal surface of the gonocoxite and one strongly enlarged, asymmetrical, foliform seta on the distal division of the subapical lobe.

Taxonomic notes. Culex phyllados  can be recognized by the following characters of the male genitalia: 1) the presence of 2–5 foliform setae on the tergomesal surface at the level of the subapical lobe of the gonocoxite (for details see Fig. 1View FIGURE 1 B in Sallum & Hutchings 2003); 2) the distal division of the subapical lobe of the gonocoxite is divided into two arms, a relatively short and broad arm and a long, strong columnar arm; 3) the most proximal arm with one long, strong, apically hooked seta (h), one relatively long, narrow, pointed saberlike seta (s), three subequal, narrow appressed foliform setae (f) and one long, strong, saberlike seta (s) ( Fig. 1View FIGURE 1 D); 4) the most distal arm is long, strong, nearly straight and bearing one large strongly asymmetrical, nonstriate foliform seta, with a well developed lobe projecting distally from the apex ( Fig. 1View FIGURE 1 D); 5) the gonostylus is short, strong, curved at midlength, possessing a patch of spicules at midlength on dorsal surface, bearing a crest of short, scattered spicules extending distally from widened part to apex of apical snout on ventral surface; and 6) apical snout of the gonostylus short ( Fig. 1View FIGURE 1 C).
