outer with strong erect external setae; gonocoxites with close set bent setae on distal 

 margins, the medial and lateral strongest. Wing length 2.6-3.0 mm. 



Nearctic material examined of E. cincinnata: 



CANADA: Ontario, Manitoulin, Killarney State Park, 31.viii.1994, 1 male; USA: 



Michigan, Ottawa National Forest, Sylvania Wilderness, ancient maple forest, 



3.ix.l994, 2 males; USA: Wisconsin, Rib Mountain State Forest, 4.ix.l994, 1 male 



(Chandler). 



British material of E. cincinnata: 



WALES: Denbigh, Loggerheads Country Park, 14.x. 1994, 1 male (Chandler). 



Exechia cincta Winnertz 



The male genitalia were figured by Dziedzicki (1915); the ovipositor was figured by 

 Chandler (1977) from a French specimen. E. cincta has been found at a dozen sites 

 scattered across southern ENGLAND: Cornwall, Devon, Hants, Berks, Surrey, 

 Hereford, Worcs and South WALES: Cardigan. 



Exechia macula nom. n. 



Mycetophila maculipennis Stannius, 1831, not Say, 1824 [ = Leia winthemii Lehmann, 



1822] 



Exechia maculipennis (Stannius, 1831) 



As indicated by Chandler (1998c) maculipennis Stannius is a junior primary 

 homonym. The replacement name proposed here is a noun in apposition ( = spot, 

 referring to the small faint median wing spot across the basal third of the median 

 fork, absent in other British Exechia species). Identification of this species is based on 

 the genitalia figures by Dziedzicki (1915). 



British material of E. macula: 



ENGLAND: Norfolk, Bure Marshes, Woodbastwick, water trap, 1 7-3 l.viii. 1989, 1 



male (A. Foster and D. Procter). 



Exechia pectinivalva Stackelberg 



Stackelberg (1948) figured the male genitalia. It was found at 43 sites in WALES 

 (all vice-counties except Monmouth and Flint), mostly blanket or raised bog and 

 valley fens, by the NCC wetland survey. There are also a few records from similar 

 sites in ENGLAND: Shropshire and Cumbria, an old record for Crowborough, 

 Sussex (1916) and one record from SCOTLAND: Perthshire, Black Wood of 

 Rannoch (1987). 



Exechia repandoides Caspers 



This species is closely related to E. repanda Johannsen, differing most obviously in 

 the shorter blunt outer lobe of the gonostylus. Caspers (1984) figured the male 

 genitalia. It has been found at several scattered broad-leaved woodland and carr sites 

 in southern ENGLAND: Oxon, Gloucs, Cambs, Norfolk and Suffolk.
