Trigonalidae has been upheld by the 2013 paper co-authored by Lelej (who had previously argued for Trigonalyidae): "the stem adopted by Cresson, who establishes the new family-group taxon, must be accepted as the correct spelling, namely Trigonalidae"

Cresson (1887) was the first to use Trigonalys to form a family-rank name (Trigonalidae) but this was apparently overlooked by others. Bischoff (1938) attributed the family to Krieger (1894). Many spelling variants have been proposed (listed in Bischoff 1938 and Weinstein & Austin 1991) due to the ambiguity of the root of Trigonalys. Based on Westwood's definition of the genus Nomadina: "genus novum...Trigonalydi proximum" (Westwood, 1868) the stem of Trigonalys is Trigonalyd-, which would make Trigonalydidae the correct spelling (H.D. Cameron*, pers. comm.). Since the root is ambiguous, we have used the first and most commonly used spelling, Trigonalidae.
