Abstract. Recent collections of pseudoscorpions resulted in a first record and a new species from Iran. Olpium
omanenseMahnert, 1991 originallydescribedfrom Oman is recordedforthefirsttimefrom Iran.Threecongeneric
specieswith similarmorphometriccharactersand trichobothrial patterns, Olpiumintermedium Beier, 1959, O.lind-
bergi, Beier, 1959and O. omanensecan beseparated bythesetal numbersonthe posteriormarginofthecarapace
andtergiteI.Also,specimensreportedasOlpiumlindbergiBeier,1951 fromPakistanwereprobablymisidentifiedand
belongtoO.omanense.The newspeciesCardiolpiumbisetosumsp.nov.isdescribed based on malesfrom Markazi
province,western Iran.Morphometricdataisgiven incomparisontorelated species.

Zusammenfassung. Olpiidae (Arachnida: Pseudoscorpiones) aus dem Iran: Beschreibung von Cardiolpium
bisetosum sp. nov. und Olpium omanense. Bei Pseudoskorpion-Erfassungen im Iran wurden ein Erstnachweis
und eine neue Art gefunden. Olpium omanense Mahnert, 1991 wurde ursprünglich aus dem Oman beschrieben
und kann nunzumersten Mal im Iran nachgewiesenwerden.DreiengverwandteArten mitähnlichen morphome-
trischen Eigenschaften undTrichobothrien-Mustern, Olpiumintermedium Beier, 1959, O. lindbergi, Beier, 1959 und
O. omanense können anhand der Anzahl der Setae am posterioren Rand des Carapax und amTergit I unterschie-
den werden. Bei den Nachweisen von OlpiumlindbergiBeier, 1951 aus Pakistan handeltes sich wahrscheinlich um
Fehlbestimmungen -alle Individuen gehören zu O. omanense. Eine neue Art Cardiolpiumbisetosum sp. nov.wird
nach Männchen ausder Markazi-Provinz imWesten Irans beschrieben.Vergleichende morphometrische Daten zu
