Iberina difficilis (Harm, 1966)

Figs 9A–C

Material. 1 ♂ (NMNHS), Slavyanka Mts, near Shabran Peak, N 41.3896 ˚, E 23.6080, 2000 m, 05.07– 10.08.2006, 1 ♂ (NMNHS), 17.10.2006 – 09.06.2007, 1 ♂ (NMNHS), 10.06– 02.07.2007, soil traps, N. Simov & M. Langourov leg., coniferous forest ( Pinus heldreichii with undergrowth of Juniperus communis ssp. nana Syme).

Remarks. Known from France, Italy, Central Europe and Romania (Nentwig et al. 2021; World Spider Catalog 2021). First record from the Balkans. All palps of the specimens from Bulgaria were twisted and expanded due to the soil trapping, but the shape (Figs 9A–C) of the palpal structures (Em, ED and RTA) fits well to the original description by Harm (1966).
