Keroplatus dispar Dufour, 1839

Material examined. Figure 1. Romania: Cluj-Nap- oca, Mikó Garden, unused old botanical garden with old trees, 373 m a.s.l., 46.7635° N, 023.5804° E, 15 Septem- ber 2014– 20 October 2014, Kolcsár L.-P. leg., 1 male, DIPT-JS-2016-0277.

A very rare European species, reported from France, Kaliningrad, Sweden ( Matile 1986), Russian Karelia ( Polevoi 2000), Norway ( Økland and Søli 1992), Czech Republic and Slovakia ( Ševčík and Košel 2009a), and Belgium ( Chandler 2013). Keroplatus dispar was redescribed by Matile (1986), but Kjaerandsen et al. (2007) claimed that both K. dispar and K. tuvensis Zaitzev, 1991 may actually fall within the intraspecific variation of the widespread K. testaceus ( Dalman, 1818) . The male speci- men studied by JS fits well to the illustrations provided by Matile (1986, 1990) (inner view of gonostylus, 9th tergite and proctiger), and thus we report the species here for the first time from Romania. Keroplatus larvae spin mucous webs on the surfaces of polyporous fungi and feed mostly on fungal spores ( Matile 1990).
