Diagnosis. Wing length 2.3–2.4 mm. Mesonotum mat greenish-grey; prescutellar setae present; fore tibia with one lateral seta; mid tibia with two lateral setae; abdomen greenish; calypter whitish, fringe white; halter yellowish. Aedeagus (Fig. 2): tubular and sclerotized; mesophallus elongated and dorsally sclerotized with a completely sclerotized apex; distiphallus slightly sclerotized, coiled, forming two tubules that are fused basally and separated distally; hypophallus sinuous, sclerotized dorsally with a strongly sclerotized apex; hypandrium with apodeme; surstylus with two to five spines; cercus with about 20 spines internally.

Host-plant. Fabaceae— Vigna luteola (Jacq.) Benth.

Distribution. Barbados, * Brazil, Cuba, Dominica, Guadeloupe, Peru, Puerto Rico, Saint-Vicent, USA.

Material examined. Brazil, Pará state, Belém: Universidade Federal do Pará ( UFPA), 1º28′32.1″S, 48º27′22.3″W, 05-XII-2018, N. Monteiro [collector], ex leaf of Vigna luteola (4 ♂); same location, 05-XII-2018, N. Monteiro [collector], ex leaf of Vigna luteola (5 ♀) .

Comments. According to the identification key presented by Sousa & Couri (2014) Japanagromyza inaequalis can be distinguished from other Neotropical species of genus Japanagromyza by: the pre-scutelar setae present; mesonotum greenish; halter completely yellow; and arista slightly pubescent. Korytkowski (2014) affirms that J. inaequalis is morphologically similar to J. peruana Korytkowski , distinguished by the distiphallus, the black-greenish mesonotum in J. peruana and the sclerotized hypophallus in J. inaequalis . This species is known to form mines on leaves of plants of the genus Vigna Savi , creating greenish blotches on the surface of the leaf.
