Wings
have distinct spots or white areas or light-colored scales on the veins and
the costal margin _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 9
3. Wing scales are not grouped in spots but
evenly spread on thee veins. The
legs and palpi have dark scales. (a

Wing
scales grouped in darker spots that are more distinct. The palpi may have dark scales or are
ringed with white _ _ _ 4
4. The palpi segments have narrow white
rings at their apices. The terminal
segment has a white apex. There are
white or light
yellow
knee spots (= apices of the femora).
Wing spots are usually distinct (Fig. 2)_ _ _ _ _ _ _

palpi's scales are either completely black or rarely there are pale scales
present_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 5

Spots on the wings are
very distinct, and knee spots are present.

6. The wing
apex has a distinctive copper-colored or golden patch of scales. The mesonotum has a broad, median,
longitudinal
brownish
yellow stripe _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

7. The wings are 5-6 mm. long. The stem vein of the 2nd longitudinal
vein beyond the dark spot has some scattered scales
(Fig. 3) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles earlei Vargas
The
wings are rarely more than 5 mm. long and mostly less. The stem vein of the 2nd longitudinal
vein beyond the dark spot has
closely appressed scales with none scattered about _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ Anopheles occidentalis D. & K.
8. The mesonotum is colored uniformly and
with no distinct stripe. Species
occur east of the Rocky
Mountains from Canada
to the Gulf of
Mexico (Fig. 4) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ Anopheles quidrimaculatus
Say
The
mesonotum has a pale brownish-yellow stripe that fades anteriorly. species occur in the Rocky Mountains and west.
The dark spots of the wings are often
more dense _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles freeborni Aitken
9. The wing's costal margin is dark save
for a white or yellowish-white spot at the extreme wing apex. Vein #6 has three dark
spots separated by white scales.
a. The Stem of Vein #5 has dark scales _ _
_ _ _Anopheles crucians Wied (Fig. 6). & Anopheles georgianus King
b. The Stem of Vein #5 has all white scales
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles bradleyi King
The
wing's costal margin has 2 white spots, one near the apex and a larger one
at the outer 1/3rd near the apex of the
subcostal
vein. Vein #5 has only 1 or 2 dark
spots _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 10
a. The wing's costal margin has alternating
black and white spots along its entire length. Fringe spots alternate with black
and pale spots (Fig. #7) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ Anopheles
gambiae
10. Wing veins
#3 and #5 are dark in color. Vein
#6 has a short basal black spot separated by a light area from the dark
apical
1/2. Wing fringe has no pale spots at the vein tips. The palpus is black (Fig. 5) _ Anopheles punctipennis
Say
Wing
veins #3 and #5 have sales that are pale in color in their central
areas. The basal half of Vein #6 is
white and the apical
half
is black. The wing fringe has pale
spots at the tips of veins_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

11. The terminal segment of the palpus is
completely white. Wing Vein #4 is
