ADULTS

 

1.  The scutellum has three slight lobes (occur in South America) _ _ _ _ _ _  Chagasia spp. Cruz

 

     Scutellum is shaped like a crescent and is evenly rounded _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _  2

 

The head is round. There are anterior prenotal lobes or "collar" behind the head (Fig. 1)  _ _ _ 6

 

2.  The stem of the wing's 2nd fork cell is wavy _ _ _ _ _ _ _ _ _ _ _ _ _  Bironella spp. Theobald

 

     The stem of the wing's 2nd fork cell is straight (Fig. 2) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Anopheles spp. Meigen  3

 

3.  The thorax is more or less black with a broad gray line from the neck to the scutellum   _  _ _ Subgenus:  Stethomyia Theobald

 

      Designs on the thorax are not like previously described  _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _  4

 

4.  Wings seldom have more than two pale spots on the costa (Fig. 3).  The sidepiece of male genitalis has 1-2 tough basal spines on

           tubercles    _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _   Anopheles spp. Meigen

 

      Wings have 4 or more pale costal spots (Fig. 4) _ _ _ __ _ _ _ _ _  _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 5

 

5.  The sidepiece of male genitalis has one spine at its base and two beyond (American species)  _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Subgenus: Nyssorhynchus Blanchard

 

      Male genitalis sidepiece has a few weak spines near its base that are not set on tubercles (Old World species) _ _ _ _ _ _ _ _ _ _

            _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Subgenus Myzomyia Blanchard

 

6.  The head is round.  There are prenotal lobes or collar behind the head. The hind leg has a paddle (Fig. 1) (South American species)_

       _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _   Sabethes spp.

 

 

LARVAE

 

7.  The larva's body is heavily clothed with short hairs in addition to the regular number of hairs.  There are leaflets of palmate tufts considerably expanded apically and each ending in a long central hair.  The anterior flap of the spiracular apparatus is extended into a long, heavy bristlelike structure  _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Chagasia spp. Cruz

 

      a.  Larval body is not covered with fine hairs.  The leaflets of palmate tufts are different from that described previously.  There

              is no elongation of the anterior flap of the spiracular apparatus_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _  8

 

      b.  A dark sclerotized boss occurs at the base of the ventral brush or hairs on the siphon occur singly_ _ _ _ _ _ _ _ _ _ _ _ _ _  9

 

8.  There are 2 pairs of feathery hairs on the thorax_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ __ _ _ Bironella spp. Theobald

 

      Feathery hairs on the thorax do not exceed one-pair (Fig. 5 & Fig. 6) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _  Anopheles spp. Meigen

 

9.   A Pecten is present on the siphon. The ventral brush has more than one pair of hairs and a dark boss occurs at its base.  Hairs

              on he siphon are scarce or absent  _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _  (Fig. 7)  (South American species) Haemagogus spp.

 

     There are no pecten or dark boss present, & ventral brush has only one pair of hairs, and hairs on the siphon occur singly

           (Fig. 8)   (South American species)     _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _    Sabethes spp.
