Remarks. Mathis & Zatwarnicki (1995) stated that the holotype of P. angustigenis is in Berlin, but it could not be found recently and was probably never actually deposited there (J. Pohl in corresp., May 2021). Becker (1926) noted that Kertész originally collected the type specimen and contrary to the other species described in the same work, did not state that the specimen was deposited in “Meine Sammlung” (“my – i.e. Becker’s – collection”). Therefore it is assumed that Becker sent the specimen back to Kertész, whose collection was deposited in Hungarian Natural History Museum in Budapest where it may have been destroyed in the 1956 revolution which saw the bombing of the main building of the museum (Evenhuis 1997), although it is possible that it may have survived within an acalyptrate collection which was being held elsewhere at the time (Földvári & Papp 2007). If the latter, however, it has not come to light since. At the locus typicus in Croatia P. angustigenis is common and is seemingly the only Ptilomyia species recorded in that country to date.
Ptilomyia angustigenis was misidentified as P. orsovana by Beschovski (2009) and Papp (1975), and probably also by numerous subsequent authors. Published records standing under the name ” P. orsovana ” refer at least partly to P. angustigenis, including all of the records previously published by the present author. On the other hand, some of the published records of P. angustigenis may actually be of P. kairensis. Where the criteria used in the identification of species in past papers were not specified in detail it is extremely difficult to reliably interpret the published records. Based on the material presented here, however, P. angustigenis is widely distributed in Europe and is the only species known to occur in Central Europe. This minute species is easily overlooked, and this may explain gaps in the known distribution. Ptilomyia angustigenis has not so far been recorded from Scandinavia, European Russia, the British Isles or the Benelux region, however, which may indicate a northern (and probably eastern) distributional limit, with the most northerly records known to date being from north Germany at about 53°N. Ptilomyia angustigenis has mainly been recorded from freshwater wetland vegetation in standing waters or rivers. In Germany almost all specimens have been swept from Phragmites stands. At least regionally P. angustigenis appears to be a common species.
