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).
