New record

SWEDEN: 1 ♂, 1 ♀, Malmö, Bunkeflostrand, Malaise trap, 16 Jul.–1 Aug. 2009, leg. B.W. Svensson ( MZLU).

Distribution

Biology

The specimens were collected in an area with shore meadows on the west coast in the south of Sweden. The larva inhabits shallow water bodies; both natural and artificial and preimaginal stages are very tolerant of desiccation and temperature fluctuations ( Zilahi-Sebess 1931; Valkanov 1941; Disney 1975).

Remarks

The male keys out as D. bilineata in Dominiak (2012) . The associated female has the subgenital plate with broad lateral processes and a more hearth-shaped notum in contrast to the isosceles triangularshaped notum of D. bilineata shown in Dominiak (2012).
