Records of Odonata collected above 800m a.s.l.on Gunung Penrissen in western Sarawak are presented. A short note on the location of Mount Merinjak, the type locality of several species, is included. Notable records include two new species from the Platystictidae, Bornargiolestes species and Acrogomphus jubilaris. Previously unpublished records from Annah Rais, a location at the foot of Gunung Penrissen, made in 2005 and 2006, are included in an appendix.

In February 2012, Odonata were recorded and voucher specimens collected in Luzon, The Philippines. The focus of study was set on localities near Dinapigue and San Mariano (Isabela Province), sites in Casiguran (Aurora Province) and on Polillo Island (Quezon Province). 60 Odonata species were recorded. Three are new to science and have been formally to be described. Four species were recorded for the first time in Luzon. Amphicnemis furcata and Diplacodes nebulosa were rediscovered after several decades since they were last documented from Luzon.

Karst poljes (or poljes) are specific geological formations of the Dinaric Alps and are important wetland areas of high biodiversity value. The dragonfly fauna of poljes in Bosnia and Herzegovina is poorly researched and mostly unknown. In order to in-vestigate dragonfly species and habitats in these specific and interesting habitats, field research was conducted from April to October 2011 in Livanjsko polje (west Bosnia), the largest periodically flooded karst polje in the world. The number of re-corded species indicates high species richness of this area, 41 dragonfly species in total were observed, of which 25 species are new for the research area. Description of habitats and dragonfly communities from 34 surveyed localities is presented. The most interesting are the records of Chalcolestes viridis (Vander Linden, 1825), na-tionally rare species and NATURA 2000 species Coenagrion ornatum (Selys, 1850). The results of this research significantly contribute not only the knowledge of dragonfly fauna of poljes but also the overall knowledge of dragonfly fauna of Bosnia and Herzegovina.
