Guglya, Yuliia, 2025, Rearing mining flies (Diptera: Agromyzidae) from host plants as an instrument for associating females with males, with the description of two new species. Report 2, Zootaxa 5658 (1), pp. 1-86 : 9-11

Agromyza paralucida Guglya

( Figs. 13–15 , 114 )

Material examined. Ukraine: Kyiv Region: near Rzhyshchiv , ecostation“Hlyboki Balyky”, 49°57'44"N, 31°07'08"E, 21.vii.2021 —pupation outside the mine, 1–2.viii.2021 —imago, Yu. Guglya, ex Setaria viridis (4♂); Kharkiv Region: Kharkiv, City Center, 50°00'N, 36°14'E, 1.vii.2022 —mines with larva collected, 16–20.vii.2022 —imago Yu Guglya, ex Setaria viridis (6♂ 2♀) .

Hosts. Poaceae : Setaria viridis (L.) P. Beauv.—the first recorded host plant..

Mine. ( Fig. 13 ) Several larvae form a greenish blotch mine at the leaf apex. Pupation takes place outside the mine in the soil.

Puparium. ( Figs. 14, 15 ) Orange-brown, glossy, 2.8 mm long, with deep segmentation; surface quite smooth except for three-row spine bands between all segments, and with two posterior segments wrinkly. Both posterior spiracles are set on one stout conical protuberance; dark brown, with three elongated bulbs set in a circular configuration at acute angles to each other. Anal plate orange-brown, directed ventrally, not protruding above the surface of the puparium when viewed from side.

Cephalopharingeal skeleton. ( Fig. 114 ) Right mouthhook is scarcely larger dorsally than the left, both with ventro-anterior portion wide and triangular. Both mouthhooks bear two strong accessory teeth. Mouthhooks and intermediate sclerite strongly sclerotized, dorsal cornua and ventral cornu much less so. Lower dorsal cornu 4× as wide as upper ones and less sclerotized. The ventral cornu bears an elongated “closed” window medially. Indentation index 86.

Distribution. Ukraine.

Comments. Male and female genitalia depicted and discussed in Guglya (2020).
