Calycomyza rolandrae Monteiro & Esposito, 2017

Calycomyza rolandrae Monteiro & Esposito, 2017: 575 .

Diagnosis. Wing length 2.0– 2.1 mm. Fronto-orbital predominantly yellowish, greyish in the upper half; face greyish; pedicel brown with margin yellowish; legs brown, with apex of femur and base of tibia yellow in the fore leg; calypter greyish, fringe brown. Aedeagus (Fig. 1–3 in Monteiro & Esposito 2017): basiphallus slightly sclerotized; mesophallus slender with two plate-like extensions basally and distal end bent ventrally in lateral view; distiphallus conic with two medial process long, fused and about the same length as the distiphallus.

Host-plant. Asteraceae— Rolandra fruticosa (L.) Kuntze.

Distribution. Brazil.

Comments. According to Spencer (1990), many of the Calycomyza species that mine leaves of Asteraceae and Lamiaceae present similarities in the shape of genitalia, expecially in the aedeagus (usually a tubular mesophallus and a distiphallus with lobes separated forming a tubule distally), forming a informal species group ( C. humeralis group in Spencer (1990) and C. jucunda group in Sasakawa (1994)) without phylogenetics analysis that support it.. Calycomyza rolandrae presents a similar pattern in aedeagus, differing from the others by the mesophallus not enlarged basally and the shape of the extensions present in the distiphallus, stoutest than other species and with same length of didtiphallus.
