Fig. 12–22 View FIGURES 12 – 16 View FIGURES 17 – 22

Description. Wing length 1.7mm in male and 1.8mm in female. Penultimate section of CuA1 0.52 times the length of the last section; transversal vein r-m situated at middle level of the discal cell. Gena-to-eye ratio 0.15. Acrostichal setae in six rows; dorsocentral setae 0+3 (anterior only a little longer than the acrostichals).

Coloration. Ocellar triangle brown; fronto-orbital plate brownish to upper orbital seta, distinctly yellow below; face grayish; frons brownish in upper half, distinctly yellow below; escape brown pedicel brown first flagellomere brown; palpus brown; gena yellow. Mesonotum brown with small yellow patches at hind corner; notopleuron yellow; anepisternum brown with border yellow; anepimeron brown with border yellow; legs brown with apex of femur and base of tibia yellow in the fore leg. Calypter white with margin black; fringe black. Halteres yellow.

Male genitalia ( Fig. 12 View FIGURES 12 – 16 to 16). Epandrium with 8 to 11 spines at hind corner; surstylus subtriangular with 3 or 4 spines and some slender setae; hypandrium V-shaped, without apodeme; basiphallus weakly sclerotized; mesophallus claviform with a digitiform projection basally; subtriangular sclerite present between mesophallus and distiphallus; distiphallus compact, fused in basal half with lateral expansion basally and two tubules rotated in opposite directions over the distiphallus; ejaculatory apodeme short, enlarged apically.

Female genitalia ( Fig. 17 View FIGURES 17 – 22 to 21). Ninth abdominal sternite wider apically; four pairs of marginal setae, the lateral pair smaller than others; ninth abdominal tergite slender, ending before the apex of the ninth abdominal sternite and with a pair of long apical setae; cercus elongated with four tactile sensilla; spermatheca rounded spermatic duct sclerotized in apex; eggs guide subquadrangular; ventral receptacle T-shaped.

Host-plants. Hyptis mutabilis (A. Rich) Briq. and Hyptis sp. ( Lamiaceae ). Larvae forming star-shaped blotch mine with a mass of black frass accumulate in center ( Fig. 22 View FIGURES 17 – 22 ).

Etymology. In Greek mythology, a dryad is a tree nymph who is an integral part of their trees, such that if the tree died, the dryad associated with it died as well (similar to the leafminer fly and its host-pant).

Distribution. Brazil (Pará).

Remarks. Mines of Calycomyza dryas sp. nov. are similar to mines of Calycomyza hyptidis, Spencer , however this species can be distinguished by the mesophallus with a posterior digitiform projection basally and the distiphallus that is fused in the basal half.
