Guglya, Yuliia, 2021, Rearing mining flies (Diptera: Agromyzidae) from host plants as an instrument for associating females with males, with the description of seven new species, Zootaxa 5014 (1), pp. 1-158 : 14-16

Ophiomyia asparagi Spencer

( Figs. 29–32 , 326 )

Material examined: Ukraine: Kharkiv Region: near Petrivske , 49°10’N, 36°58’E, 11.viii.2013, Yu. Guglya, ex Asparagus officinalis (1 puparium). The rest of material are listed in Guglya (2015) .

Hosts. Asparagaceae : Asparagus officinalis L., A. acutifolius L. ( Spencer 1990).

Mine. ( Fig. 30 ) The larva feeds as an external stem miner. Mine tunnels, larva and puparium are easily visible from outside. Pupation takes place subepidermally ( Fig. 29 ).

Puparium. ( Figs. 31, 32 ) Yellow to orange, slightly shining, 3.0 mm long, with scarcely visible segmentation; surface quite smooth. Posterior spiracles set on short protuberances joining towards their bases; yellow, fan-shaped, with five sessile bulbs arranged in irregular row. Anal plate not protruding above the surface of the puparium viewed from the side and directed ventro-posteriorly.

Cephalopharyngeal skeleton. ( Fig. 326 ) Right mouthhook smaller than the left, both with ventral portion sharply abducted. Each mouthhook bears two accessory teeth. Intermediate sclerite long, narrow and straight, weakly sclerotized centrally, 1.75× as long as height of the left mouthhook. The dorsal cornu bears a narrow and long “open” window. Dorsal and ventral cornua are well sclerotized. Distinct transverse bridge connecting bases of dorsal and ventral cornua. Indentation index 58.

Female genitalia: Discussed in Guglya (2015).

Distribution. Croatia, France, Greece, Hungary, Italy, the Maltese Islands, Slovenia, Spain ( Papp & Černý 2015). In Ukraine found in a single locality ( Guglya 2015).
