Antennae with 11 antennomeres, antennal club composed of 5 antennomeres, with sensorial appendages which are inserted on lower part and oriented towards upper part of antennomere, antennomeres 3–10 strongly transverse (Figs 32, 49). Elytra tetragonal, dilated posteriad (Fig. 33), shorter than pronotum. Procoxal cavities (Figs 34, 50) rounded on anterior margin, lacking excision, prosternum and proepisternum fused.Abdominal sternites lacking deep, transversal sulcus, visible sternite 2–5 with shallow basal impression (Figs 27, 46).

Etymology. Named after our friend Dušica Šoljaga, owner of a beautiful house which is a base of our expeditions to the coastal part of Montenegro.
Natural History. The majority of specimens (holotype and 27 paratypes) of newly described species was collected by the soil washing of a sample taken near and around a solitary oak (Fig. 85) on the border of terrace garden together with Ubychia ganglbaueri (Reitter, 1912) and an undesribed species of Cephennium and Tychobythinus in May 2023 and March 2024. Several specimens were collected in Rumija Mts. in about 675 m a.s.l. and two females also in coastal Mediterranean forest under junipers tree near Blizikuće village.
