Abstract: Arknotrombium arknesianum gen. n., sp. n., Hauptmannia kotorensis sp. n., both from Montenegro, H. podora- sensis sp. n. and Abrolophus pseudolongicollis kiejstuti subsp. n., both from Bosnia and Hercegovina are described. Leptus mariae Haitlinger is new to the of Bulgaria, Leptus josifovi Beron is new for the fauna of Bosnia and Hercegovina, Erythraeus budapestensis Fain et Ripka is new for the fauna of Bosnia and Hercegovina and Montenegro, Allothrombium fuliginosum (Hermann) is new for the fauna of Bosnia and Hercegovina, Bulgaria and Serbia and Eutrombidium trigonum (Hermann) is new for the fauna of Bulgaria. Redescription of Erythraeus styriacus Turk is given. Key words: Acari; Erythraeidae; Trombidiidae; Eutrombidiidae; new genus; new species; new subspecies; Bosnia and Hercegovina; Bulgaria; Crotia; Montenegro; Serbia; Slovenia

Introduction Montenegro and Serbia. Leptus josifovi, Charletonia kren- dowskyi and Eutrombidium trigonum were obtained from In Bosnia and Hercegovina, Montenegro and Serbia, unidentified Orthoptera; the remaining species were ob- mites belonging to the families Erythraeidae and Trom- tained from herbaceous plants. Measurements below are µ bidiidae are unknown, excluding Abrolophus tardus expressed in micrometers ( m). The terminology of struc- (Halbert, 1915) and Erythraeus (E.) styriacus Turk, ture and setal notation for erythraeids and trombidiids are adapted from Southcott (1986, 1992) and Haitlinger 1981 found in Bosnia and Hercegovina (Turk 1981).
