Thorax. Ac 22–24; Dc 23–26; Pa 6–7; Scts 13–13 coarse and 9–12 finer setae anteriorly. Scutal tubercle absent.

Wings. VR 1.13–1.15. Brachiolum with two setae. M 1–2, rm 0–2, R 37–40, R1 47–55 and R4+5, 65–70 setae, remaining vein bare. Squama with 12–13setae.

Legs. Scale on front tibia 53–54 µm long. Tibial combs of mid and hind legs partly fused; mid tibial spur 60–66 µm long; hind tibial spur anterior 77–100 µm, posterior 54 µm long. Lengths and proportions as in Table 13 .

Genitalia ( Fig. 18 d). Setal patches on sternite VIII with 24–25 setae. GC IX with 1–3 setae. Segment X with 12–14 setae. Seminal capsule 117 µm long. Notum 62–63 µm long, rami 125 µm. Gonocoxapodeme near 147 µm long. Cercus 91 µm long.

Remarks. This is the first description of the female of E. callophylli , which is now known from its male, female, pupa and larva.

The following specimens are 4 larvae very distinct, here described as four morphotypes.
