64 (sub)species from 10 families of Odonata were recorded throughout five provinces of Papua New Guinea, including the Bismarck islands of New Britain and New Ireland, from mid-May to early July 1997. The field trip led to the description of two new dam-selfly species (Gassmann, 1999; Gassmann, 2011) and one possibly new damsel- and dragonfly taxon, respectively. For several taxa, considerable range expansions are pro-vided. Agriocnemis aderces Lieftinck, Hemicordulia hilbrandi Lieftinck, Nososticta calli-sphaena (Lieftinck), Nososticta plagioxantha (Lieftinck) and Tanymecosticta fissicollis (Lieftinck) are recorded for Papua New Guinea for the first time. Brachydiplax duiven-bodei (Brauer) is a new record for New Britain. Agriocnemis femina (Brauer), Morton-agrion martini Ris, Nososticta africana (Schmidt), Rhyothemis resplendens Selys, Xiphi-agrion cyanomelas Selys, Brachydiplax duivenbodei (Brauer) and possibly Brachydiplax denticauda (Brauer) are recorded from New Ireland for the first time.
