1. The
abdomen has feathery lateral hairs on the first 6 segments. All hairs on the head are small and
occur singly. Larvae are
found in tree holes _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles barberi Coq.
The
abdomen has feathery lateral hairs only on the first 3 segments _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ 4
2. Feathery
hairs are well developed on segments #1 to #7 of the abdomen. Both inner and outer hairs of the
clypeus are long and
slender. Inner clypeal hairs are widely separated and feathery on
the outer half. The outer clypeal
hairs have tiny branches
on
the outer half _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
Anopheles
albimanus Wied.
Feathery hairs are well developed on segments #2 or #3 to #7 of the
abdomen. The inner and outher
clypeal hairs are different
from
the previous description _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 3
3. The outer hairs of the clypeus are not
tightly branched dichotomously_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ 4
The
outer hairs of the clypeus are tightly branched dichotomously _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ 6
4. The inner, outer and posterior hairs of
the clypeus are long, single, not quite equal and widely separated at their
bases _ _ _ _ 5
The
inner and outer hairs of the clypeus are long and usually with 1 to 5
branches near the tips. The
posterior clypeal hairs are
short and may be branched, while the
inner hairs are closely set at their bases _ _ _ _ _ _ _ _ _ Anopheles atropos D. & K.
5. The inner angle of each posterior plate
of the respiratory apparatus is extended into a long, sclerotized tail (the
tails project
from
the water in living larvae) _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles
pseudopunctipennis Theo.
The
inner angle of each posterior plate is rounded and not extended into a tail
_ _ _ _ _ _ _ Anopheles franciscanus McC.
6. The
abdominal segments #4 & #5 have 2 conspicuous hair tufts anterior to
the feathery tuft (Nos. 2 and "0"). The tufts are about
equal in size and have 4 to 9 branches _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles
crucians Wied.
The
abdominal segments #4 & #5 have only one hair tuft (No. 2) anterior to
each feathery tuft. Hair
"0" is absent or vestigial,
but
if present the inner clypeal hairs
are lightly feathered toward their tips _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ 7
7. The inner hairs of the clypeus are
divided into 2 or 3 branches or feathery toward their tips _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ 8
The
inner hairs of clypeus are usually not branched but they may rarely be
divided into 2 branches near the middle _ _ _ _ 9
8. The inner hairs of the clypeus are
arranged so close together that an extra tubercle of the same size cannot
fit between their
bases.
Each hair is thinly feathered on the apical half. The occipital hairs (Nos., 8 & 9) are small and each with
2 to 4
branches
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ Anopheles
walkeri Theo.
The
inner hairs of the clypeus are not arranged as close together so that an
extra tubercle of the same size can be put between
their
bases. The inner clypeal hairs have
2 or 3 branches near the middle.
The occipital hairs have many branches and
stout
shafts _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles earlei Vargas
9. The inner hairs of the clypeus are
separated at their bases by at least the diameter of one tubercle. Feathery tufts are well
developed
on segments #3 to #7. A feathery
tuft on segment #2 is often well developed. Occipital hairs are well developed
with
8 to 10 branches _ _ _ _ _ _ _ _ _
_ _ _ Anopheles quadrimaculatus Say and Anopheles occidentalis D. & K.
The
inner hairs of the clypeus are so closely packed that an extra tubercle
cannot be placed between their bases_ _ _ _ _ _ 10
10. Feathery
tufts occur only on segments #4 to #6 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ Anopheles
georgianus King
Feathery tufts occur on segments #3 and #7 _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 11
11. Feathery tufts on segments #4 and #7 are
smaller than the others. The inner
hairs of the clypeus are usually placed close
together _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles bradleyi King
Feathery tufts on segments #3 and #7 are of the same size as the
others _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 12
12. Hair No. 2 on abdominal segments #4 and
#5 has 4 to 5 branches _ _ _ _ _ _
_ _ _ _ _ _ _ _ _ Anopheles freeborni Aitken
Hair
No. 2 on abdominal segments #4 and #5 is not branched __ _ _ _ _ _ _ _ _ _
