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

. 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
).
