Morphometric measurements of Culicoides. a & b the head: where a) is length of eight basal flagellar segments of the antenna; b) is the length of the five apical flagellar segments of the antenna; c) is the length of flagellomere 10; d) is the length of flagellomere 11; e) is the length of the third palpal segment; and f) is the width of the third palpal segment. c the wing: where a) is the costa length; b) is the width of the wing; and c) is the length of the wing (arculus to tip). d & e the abdomen: where a) is the length of spermatheca 1; b) is the width of spermatheca 1; c) is the length of spermatheca 2; d) is the width of spermatheca 2; e) is the length between the chitinous plates; and f) is the width of the chitinous plates
