Phytobia (Calycomyza) ecliptae Spencer, 1963: 341, 1973b: 41; Martinez & Etienne, 2002: 29.

Diagnosis. Wing length 1.6–2.1 mm; Fronto-orbital plate predominantly brown, only yellow in the lower half; face greyish; pedicel yellowish; legs brown, with apex of femur and base of tibia yellow on fore leg; calypter white with margin black, fringe black. Aedeagus (Fig. 57a in Spencer 1963): mesophallus elongated, wider basally; distiphallus strongly sclerotized, forming two curved tubes fused basally.

Host-plant. Asteraceae— Eclipta alba (L.) Hassk.

Distribution. Brazil, Costa Rica, Venezuela (Martinez & Etienne 2002).

Comments. Calycomyza ecliptae is similar to the other species of this genus that have the distiphallus forming a pair of strongly sclerotized tubules, such as C. hyptidis Spencer and C. verbesinae Spencer, and it is differentiated primarily by the shape of the distiphallus. So far, the only known host-plant of this species is Eclipta alba, and larvae form irregular blotches on the surface of its leaves.
