Lonsdale, Owen, 2013, Japanagromyza Sasakawa (Diptera: Agromyzidae) of Africa, Zootaxa 3709 (5), pp. 445-460 : 459

Japanagromyza “female 1”

Description. Wing length 1.8–1.9mm (♀). Males unknown. Length of ultimate section of vein CuA1 divided by penultimate section: 0.7–0.8; vein r-m before midpoint of cell dm. Eye height divided by gena height approximately 9.6–12.0. Margins of ocellar triangle not entirely distinct. Lunule slightly more pruinose than frons. Face with very shallow medial carina. Clypeus with relatively broad, straight anteromedial margin.

Chaetotaxy: Ocellar seta barely longer than ocellar triangle (distinctly longer and thicker in other African species). Prescutellar acrostichal seta relatively small, less than 1/3 length of posterior dorsocentral. Katepisternum with additional 1–2 smaller setae. Fore tibia with one medial seta. Mid femur with curved posterodistal seta.

Colouration: Setae and setulae black. Halter white with stem light brown to brown. Calypter margin and hairs light brown. Body dark brown with relatively distinct green shine (more so than in Afrotropical congeners). Wing veins becoming brownish-white posteriorly.

Host. Unknown.

Distribution. RSA.

Material examined. REPUBLIC OF SOUTH AFRICA. Ndumo Game R., main road at: 26˚54.288’S, 32˚17.974’E, 4–8.xii.2009, A.H. Kirk-Spriggs (7♀, BMSA).

Comments. This series of females is described because it is clearly distinct from other African Japanagromyza , but it is not provided with an official name because of the importance of male genitalic features in the diagnosis and definition species in this genus. The species is characterized by a relatively distinct greenish shine, a pale halter and wing veins, a short prescutellar acrostichal, relatively small size, and an atypical ocellar triangle and clypeus.
