Description

Figs 25–32. Genital anatomy of two individuals of A. ater s.l., morphotype FR: 25–29 – SMNG p20100, Pisarzowice, near Lubań, PL (leg. 2014); 30–32 – SMNG p17128T1, Zgorzelec, PL (leg. 2010). 25, 30 – genitalia oriented as when the slug is first opened (although in 30 the atrium had already been opened but then folded back); 26 – the back side of the same genitalia as in 25; 27, 31 – the folded-up ligula on first opening the atrium; 28, 32 – the atrium pinned out; 29 – tubercles inside distal part of epiphallus. Ligulas are shaded olive, and the funnel turquoise. Abbreviations: bd – bursa-duct, ep – epiphallus, la – lower atrium, ua – upper atrium, flf – flap of left flank, frf – flap of right flank, ov – oviduct
