Status and distribution of the suborder Lari in Paraguay, including new country records

The Lari of Paraguay are poorly known and only three species in two families occur regularly. However recent field studies have revealed that diversity is much greater than previously thought, and several new species have been added to the country fauna in recent years. With many of these species being of only transient presence, the distribution and status of Paraguayan species is reviewed here including first reports of four species and one subspecies, and the first South American record of Whiskered Tern Chilidonias hybrida , remarkably coming from a country in the centre of the continent.
