ETYMOLOGY. — The name agenora is after the Greek prefix agenor (meaning “dignity”) for its sclerotised wings and large body size.

DESCRIPTION

Large-sized, strongly sclerotised species, with body length 19.5-21.5 mm (with head), width 5.1- 6.5 mm. Head small, significantly elongated (length/ width = 2.2-2.9 mm / 1.7-2.1 mm), about ¹⁄₇ of the total body length, antennal socket and compound eye obvious at sides, mouthparts unclear.

Pronotum

Elliptical, large, as wide as the body, with dark coloration at center, length/width = 2.9- 3.2 mm / 4.9 -5.5 mm.

Abdomen

Ten segments visible; in female, external ovipositor ( Fig. 1B View FIG ) very wide (length = 1.8 mm), and cerci at the terminal sternum; in male, body elongate, very narrow, cerci with 14 segments, forming forceps with notches ( Fig. 2C View FIG ).

Wings

Wide, coloration as in Figures 1A View FIG ; 2B View FIG ; 3B View FIG ; 4A, B View FIG ; forewing with intercalaries and rich venation, with 39-48 veins at margin; the shape of the forewing has sexual dimorphism: wide near apex in female and sharp apex in male.

Forewings

Elliptical, length/width = 14.9-16.1/ 5.5-6.7mm, with more or less parallel margins and characteristic coloration marking (dark maculas are located between R and M, beginning from M and extending to the apex of the wing to form a stripe) ( Figs 1A View FIG ; 2B View FIG ; 3B View FIG ; 4A, B View FIG ); costal area very long (about ²⁄₅ of the wing’s length); intercalaries pale; Sc simple or bifurcated near margin ( Fig. 2A View FIG ), curved upward and somewhat thickened, longer than clavus; R slightly curved and with 15-23 branches, R branches sometimes fused at margin, which is the exception of deformity to Colorifuzia ( Fig. 3A View FIG ); M branched basally and reaching apex, with 2-6 veins; CuA gently curved, expanded with 11-17 branches; CuP strongly curved; clavus short, less than a third of the wing’s length; A arc bending, with 5-8 veins.

Hind wings

Many terminal branches, with intercalaries; Sc simple; darkened R1 with 2-4 branches and Rs with 10-15 branches; M with 3-6 branches, reaching apex; CuA with more than seven veins.

Leg

Slender; legs gradually get longer from the front to the hind legs; femora more or less as long as tibiae in all legs (length of fore femora and tibiae 2.2 mm and 2.1 mm, respectively; length of mid femora and tibiae 2.5 mm and 2.2 mm, respectively; length of hind femora and tibiae 3.3 mm and 3.1 mm, respectively); hind leg with spines on the tibia, width of hind femora and tibiae 0.8 mm and 0.4 mm, respectively.
