The description of the species (as Exechia unguiculata ) was based on material collected from modern Croatia and Austria ( Lundström 1911a). The species has a European range, known from southern and Central Europe (Chan- dler 2013), including Great Britain ( Edwards 1925), Spain ( Mederos and Chandler 2014), Ukraine ( Zaitzev 2003), and is here reported from Montenegro. The spe- cies was recently removed from the list of Finnish fungus gnats (Jakovlev 2014). Note that E. unguiculata has not been recorded from Japan, as was mentioned by Jakovlev

(2011), citing Sasakawa and Ishizaki (1999). Immature stages of the species are unknown, but Exechiopsis larvae have been reared from both soil-dwelling agarics and saproxylic fungi ( Jakovlev 2011). Exechiopsis unguiculata has been illustrated only by Lundström (1911a) and Zaitzev (2003), and thus photos of the male hypopygium are provided here. The male hypopygium is characterised by a ventroapical lobe of the gonocoxite that is narrowing apically, its apex rounded, margins straight and bordered by a black frame ( Figure 11). The medial appendage of the gonostylus is curved, long and narrow, bearing three subapical black spines arranged in a row and a long apical spine ( Figs 12, 13).
