Description (male): body length 9.5–11.5 mm.

Head: 11–16 pairs of medioclinate frontal setae. Genal setae black, postgena with at least some white or yellow setae.

Thorax: proanepisternum bare.

Wing: dark hairs on lateral margin of alula as long as those on anterior margin of anal lobe. Hairs fringing calypters pale-brown.

Legs: hind tibia without long, wavy posteroventral hairs.

Abdomen: tergite 5 with orange-yellow margin on apical half or third, sometimes entirely yellow. Row of strong setae forming half circle spreading on apical third.

Terminalia: cerci and syntergosternite 7+8 darker than epandrium. Surstylus without a small posteroventral projection. Window on sternite 5 almost even with rest of base. Pregonite usually without pointed lateral extension, weak if present. Vesica and juxta as in Figs. 7–8 . Juxta in posterior view as in Fig. 9 . Female: body length 11.5 mm.

Terminalia: tergite 6 with moderately strong setae on each side evenly spaced and about equal in size, with long hairs interspersed. Tergite 7 and 8 absent. Sternite 6 and 7 covered with short to moderately long setae and hairs on posterior margin. Posterior margin of sternite 7 straight and slightly concave in middle ( Fig. 13 ). Etymology: Cady is a diminutive of Yvon Cadieux, the man who shares M. Giroux’s life. The species is named to express her gratitude for his moral and financial support during her PhD studies.
