Subfamily Culicinae, genus Culex (see Culex Classification, Subgenus Microculex). Subgenus Microculex includes 33 species.
ADULTS - Small mosquitoes; head with narrow scales on vertex and orbital line; maxillary palpus of females with 3(?) palpomeres, palpus of males as longer or longer than proboscis, with 5 palpomeres; scutum with pattern of dark, golden or silvery scales; acrostichal setae present or absent; antepronotum with narrow scales; mesokatepisternum with scales; lower mesepimeral seta present; vein R2 and vein R3 of wing with narrow scales; legs entirely dark-scaled (some species) or tarsi with basal pale bands (most species); abdominal terga dark-scaled. MALE GENITALIA - Tergum IX lobes distinct, widely separated; gonocoxite without scales; subapical lobe subapical in position, little if at all divided, proximal division with 2 rod-like setae, distal division weakly developed but usually bearing a number of setae; gonostylus simple, tapered distally; phallosome not columnar, lateral plate with long basal hook; paraproct with single row of blunt spicules. LARVAE - Antenna shorter than head, constricted beyond seta 1-A, seta 1-A inserted about 0.8 from base; seta 2-C weakly developed or absent; seta 3-P shorter than setae 1,2-P; comb with many scales in patch; siphon usually very long and slender; seta 1-S distal to pecten; saddle long, complete; seta 1-X small, branched; setae 2,3-X long, single; ventral brush (seta 4-X) with 4 pairs of setae on grid. PUPAE - Trumpet long and slender, tracheoid beyond base; meatus without slit from proximal part of pinna; seta 2-III mesad of seta 1; seta 2-VI laterad of seta 1; seta 9-VIII relatively long, subequal to length of tergum VIII; caudal lobe of tergum VIII not overlying lateral part of tergum IX; seta 1-Pa present, seta 2-Pa absent. See Genus Culex.
The immature stages inhabit epiphytic bromeliads, and less frequently bamboo internodes. Eggs are enclosed separately in gelatinous envelopes. Lane (1953) indicated that adult females prefer to feed on birds.
