Wing of Anopheles gambiae s.l. (×25 magnification); Landmarks (14) denoted by numbers. Black dot-dash line represents the wing length between landmarks 1–10. Wing width was the average value of the height of three triangles formed between landmarks: 1-2-13 (proximal triangle, black), 2-5-11 (distal triangle, red), and 2-12-14 (medial triangle, blue). Scale bar = 1 mm
