Winnertzia pustulata Spungis Diagnosis. A medium-sized, dark-brown Winnertzia with long antennae and broad wings. This species, a member of the W. tridens complex already recognized by Spungis (1992), is distinguished by male genitalic characters (Jaschhof & Jaschhof 2013: fig. 45B). The best indicator is the long gonostylus whose apex is appreciably inflated and, beyond the inflation, extended into a short, downward-sloping process that bears the pectinate claw. The gonocoxae are conspicuously broad posteriorly due to the medial bridges that are strongly bulging towards the aedeagus. We know of two species in Sweden closely resembling W. pustulata . One is described below as W. pustulatula the other is left unnamed for the time being. Characters useful for identifying these three species are explained under W. pustulatula . Distribution in Sweden. The eight Swedish specimens known of W. pustulata come from the central and northern parts of the country (Dalarna to Lule Lappmark). Material studied. Specimens listed by Jaschhof & Jaschhof (2013) and as follows. Sweden: 1 male, Lule Lappmark, Sorsele, Bissitjbäcken, 6 km N Ammarnäs, swampy boreal forest, 23 June–22 July 2016, MT, MCJ (spn CEC 1847 in NHRS); 1 male, same data but 26 June–22 July 2016 (spn CEC 1846 in SDEI); 1 male, Lule Lappmark, Jokkmokk, Kaltisbäcken NR, old-growth herb-rich boreal forest, 12 July 2016, sweepnet, MCJ (spn CEC 1845 in SDEI).
