Descripteur : ABDOMEN: Siphonal tufts
Type du descripteur : categorical
First two states correspond to species of Culex and Culiseta genus respectively.
Most Aedes species have a pair of siphonal tuft inserted close to the middle or near the apex of the siphon but species belonging to subgenus Rusticoidus have additional setae on the dorsal part of the siphon.
ABDOMEN: Siphonal tufts
ABDOMEN: Siphonal tufts
- 1. several pairs of siphonal tufts - Culex
-
This question leads to species belonging to Culex genus
- 2. one pair of siphonal tuft inserted at the base of the siphon - Culiseta
-
This question leads to species belonging to Culiseta genus
- 3. one pair of siphonal tuft inserted close to the middle or near the apex of the siphon - Aedes
-
This question leads to species belonging to Aedes genus
- 4. one pair of siphonal tuft inserted close to the middle or near the apex of the siphon and several pairs of setae on the dorsal surface - Aedes
-
This question leads to species belonging to Aedes genus, Rusticoidus subgenus.
