Described and illustrated by Ricchello (1928a) and de Meijere (1946a). There is not much congruence among the two descriptions. The one mandible with 2, the other with 1 tooth (de Meijere – Ricchello’s figure shows two pairs, not-alternating teeth). Frontal arm of cephalic skeleton short and thick. Front spiraculum with 11 papillae, rear spiraculum with 3 papillae. Ricchello’s drawing of the rear spiraculum shows 3 fan-shaped setae, like are present in the Agromyza‘s that mine on Urtica, but de Meijere does not mention anything alike (he had only one larva at his disposition, and these setae are not easily observed). Rear spiracula strikingly small. In Richello’s drawing the rear end of the abdomen is unusually elongated and pointed, in de Mejere’s it is stunted.
