Checklist of the Dolichopodidae (Diptera, Empidoidea) of the Balkan Peninsula, with first records for Bulgaria, Montenegro, North Macedonia, and for the European part of Turkey.

This paper presents 58 new records of the family Dolichopodidae for Bulgaria, Montenegro, North Macedonia and European part of Turkey, collected from 37 localities. Seventeen species are recorded for the first time from Bulgaria, six of which are new to the Balkan Peninsula, 23 species for European Turkey, three of which are new to the entire territory of Turkey, seven species for Montenegro and 11 species for North Macedonia. A checklist of the Dolichopodidae of the Balkan Peninsula is provided.

Comprehensive inventory of true flies (Diptera) at a tropical site.

Estimations of tropical insect diversity generally suffer from lack of known groups or faunas against which extrapolations can be made, and have seriously underestimated the diversity of some taxa. Here we report the intensive inventory of a four-hectare tropical cloud forest in Costa Rica for one year, which yielded 4332 species of Diptera, providing the first verifiable basis for diversity of a major group of insects at a single site in the tropics. In total 73 families were present, all of which were studied to the species level, providing potentially complete coverage of all families of the order likely to be present at the site.

Remarkable fly (Diptera) diversity in a patch of Costa Rican cloud forest: Why inventory is a vital science.

Study of all flies (Diptera) collected for one year from a four-hectare (150 x 266 meter) patch of cloud forest at 1,600 meters above sea level at Zurquí de Moravia, San José Province, Costa Rica (hereafter referred to as Zurquí), revealed an astounding 4,332 species. This amounts to more than half the number of named species of flies for all of Central America. Specimens were collected with two Malaise traps running continuously and with a wide array of supplementary collecting methods for three days of each month.
