This species has a sibling species, M. marina , on the Azores and Madeira. While it has a distinctive female, the males of the two species are very similar. However, this species has brown halteres but M. marina has yellow haltere knobs, and the hypopygia differ. Two other sibling species, in Sweden ( M. fuscoides Schmitz, 1934 ) and Great Britain ( M. yatesi Disney, 2002a ), also have brown halteres but they have brown palps and darker legs as opposed to the straw yellow palps and paler legs of M. bistruncata . The hypopygia all differ in small details. The males of all these species run to M. bistruncata at couplet 8 of the key to males of the M. pulicaria complex ( Disney 1999 ).
