Diagnosis. The eye bridge of S. svemapro is conspicuously short and the scutum lacks membranous windows, which are two characters shared with S. media , S. palifera Jaschhof , and S. simillima Jaschhof (see the key to species of Spungisomyia in Jaschhof & Jaschhof 2013: 259 ). Contrary to these and other Spungisomyia , the parameres of S. svemapro end in a single point, rather than being two- or multipointed, and have a large, rounded side lobe at about half the length, which is absent in the congeneric species ( Fig. 46 , ↓ 4). Another peculiarity is that the dorsal gonocoxal apodemes are unusually broad (↓ 5). Females and larvae of this new species are unknown.

Other male characters. Body size 1.7 mm. Head. Eye bridge without ommatidia at vertex. Antenna markedly longer than body. Scape and pedicel yellowish, lighter than flagellum. Circumfila on flagellomeres 1–11. Neck of fourth flagellomere 1.7 times as long as node ( Fig. 47 ). Palpus as long as head height, 4 setose, subcylindrical segments, apical segment longest of all. Thorax. Pronotum with 1 seta; anepisternum non-setose; anepimeron with 1 seta. Wing longer than body but shorter than antenna. Length / width ratio 3.0. M 1+2 absent. M 4 weak, separate from CuA. Legs. Foreleg: femur and tibia equally long, T 2 0.7 times the length of tibia. Empodia broad, nearly as long as claws. Genitalia ( Fig. 46 ). Gonocoxal synsclerite slightly broader than long, slightly narrowed anteriorly; ventral setae mostly short, evenly scattered except a narrow, non-setose stripe below the emargination; ventral emargination small, U-shaped, with broad, sclerotized margin; dorsal apodemes long, protruding beyond ventroanterior gonocoxal edge. Gonostylus thick, slightly bent and narrowed towards apex, 1.7 times as long as broad; apical claw small, consisting of a pectinate portion and 1–3 short, more isolated spines ventrally; 6–7 long bristles dorsosubapically. Parameres thick, strongly sclerotized, crossing each other apically, without transverse bridge; apices strongly bent dorsally. Aedeagal apodeme as long as gonocoxae, moderately sclerotized, nearly parallel-sided; apex transitioning into conical, membranous cap; base semicircularly broadened. Ducts of accessory glands distinct (not illustrated).

Etymology. The species epithet, svemapro , is an artificial word derived from Svenska Malaisefälleprojektet, the Swedish name of The Swedish Malaise Trap Project. In this way we honor the many dedicated people, mostly volunteers, involved in implementing one of the largest and most productive enterprises ever launched to inventory an insect fauna on a national scale (see Karlsson et al., in press).
