Wings (Fig. 7 a , b ). Wing length 2.6 mm. Crossveins sc-r and R2+3 absent (in holotype, Fig. 7 b ). Posterior fork longer, its stem forking opposite of anterior fork (Fig. 7 a ). Veins M4 and CuA branching with acute angle and less divergent at base of fork. Sc with 6 macrotrichia on apical half. Terminalia (Figs 11 c , d , 13 ). Tergite 9 elongated, gradually tapering into acute apex, bearing two, strong, pale and 15 dark, apico-ventral, stout setae. Cerci and hypoproct/sternite 10 retracted well in under tergite 9. Gonocoxites with a deep ventral cleft. Gonocoxite with a hyaline, apico-mesal, long seta, almost as long as gonostylus. Gonostylus elongated, with three blunt, digitate projections apically (marked as a, b & c in Fig. 13 a ), three lamellae subapically (marked as d, e & f in Fig. 13 a , b ) and two long bristles mesally (marked as g & h in Fig. 13 b ). Apical projection (a) finger-like, apically rounded, evenly broad and symmetrical. Subapical projection (b) narrow, black, apically rounded, glabrous. Basal projection (c) black, hollow, having reticulate surface pattern, glabrous except strong setae on a small projection laterally, apically rounded. Lateral lamella (d) subrectangular, high and narrow, covered with setae. Ventral lamella (e) forming a blunt ridge with row of 10 acute, short setae. Ventromesal lamella inconspicuous fold without specialised setae. Female. ( n = 4) Colouration as for male. Wings (Fig. 7 c , d ). Wing length 2.9 mm ( n = 1). Venation in radial sector variable. One (SSJAD4978-13) of four females with crossvein sc-r present (Fig. 7 d ), two females with R2+3 present and forming tiny cell, one female without R2+3 . Sc with 3-6 macrotrichia on apical half, setation otherwise as for male. Terminalia (Fig. 8 ) as described for genus. Etymology Coelosynapha heberti sp. n. is named in honour of Paul D. N. Hebert, "the father" of DNA barcoding who also led the project of barcoding the insects of Canada ( Hebert et al. 2016 ) from which the new species was located through its barcode similarity with Coelosynapha loici sp. n. It is further an expression of the importance of DNA barcoding in the new integrative science of taxonomy. Distribution The new species has a wide Nearctic range across Canada (Fig. 2 ).
