Head (fig. 2A) longer than broad; vertex between two and three times length of head, tapering; postocular setae indistinct, reaching base of eyebridge; eyebridge of four facet rows, separated by one facet diameter; interocular suture present, Y-shaped with very short stem; frontal alveolar patch trilobate with median "lobe" reaching interocular suture; frontoclypeus widened over mesal margins of eyes, produced to about eyebridge width in front of eyes; length of palps 85: 130: 150: 200; scape barrellshaped, 2.5 times length of pedicel; flagellomeres slightly asymmetrical, carrying numerous filiform ascoids and one pair of narrow digitiform ascoids; ascoids slightly longer than flagellomere; most flagellomeres positioned such as to make their measurements unfeasible; thorax destroyed in described specimen; wing (fig. 2B) length 2.1, breadth 0.84; apex of wing between R4 and R5; wing forks and apices of Sc and CuA2 widened; Sc approaching C; medial fork slightly distal of radial fork; dense circular patch of setae present dorsally of jugum, jugum widely triangular; terminalia (fig. 2C); hypandrium produced triangularly; gonostylus (not illustrated) elongate curved cylindrical, longer than gonocoxite; gonocoxite reniform; gonocosal condyles arched, platelike; triangular parameral sclerite present medially, linked basally to distiphalli; aedeagal complex surrounded by parameral sheath; basiphallus broad with wide aperture; distiphallus consisting of two symmetrical phallomeres sclerotized basally, connected to ventral epandrial plate medially; distal parts of phallomeres membranous, shovel-shaped; epandrium (not illustrated) approximately square with single aperture; surstyli elongate of even width, six times as long as wide; tenacula with tips fringed; tenacula slightly less than twice width of surstylus; epiproct round, hypoproct elongately diamond-shaped.
Remarks. Seoda labeculosa is here recorded from Luxembourg for the first time. The species is previously known from Belgium, the Czech Republic, France, Great Britain, Ireland and Lithuania (Tonnoir 1919, Nielsen 1964, Withers & O'Connor 1992, Bernotienè 2002, Ježek 2003).
