Calycomyza ipomoeaphaga Martinez, 1992: 289 (in Spencer et al. 1992).

Diagnosis. Wing length 1.4 mm. Fronto-orbital predominantly yellowish, darkened to upper fronto-orbital seta; face yellowish; pedicel brown; legs brown; calypter greyish-yellow with margin black, fringe black. Aedeagus (Fig. 22 and 23): basiphallus sclerotized dorsally at basal half, slightly sclerotized dorsally at distal half and with an intermediate extension joining the two sections along left lateral surface; mesophallus short and globose; subtriangular sclerite present between mesophallus and distiphallus; distiphallus short, forming two tubules covered laterally by a sclerotized plate.

Host-plants. Convolvulceae—* Ipomoea setifera Poir., I. tiliaceae (Willd.) Choisy.

Distribution. * Brazil, Guadeloupe, Saint-Martin.

Material examined. BRAZIL, Pará state, Belém: Avenida João Paulo II, 1º25′20.8″S, 48º26′44.2″W, 19-VI- 2017, R.R. Barbosa [collector], ex leaf of Ipomoea setifera (2 ♂) .

Comments. The shape of the aedeagus in Calycomyza ipomoeaphaga is similar to that of other Calycomyza species mining leaves of plants of the genus Ipomoea . The mesophallus of this species is similar to that of C. ipomaeae, but it can be differentiated by the shape of the distiphallus. Calycomyza ipomoeaphaga larvae form linear mines on the surface of host-plant leaves (Spencer et al. 1992).
