Die vorliegende Revision umfasst 40 Arten aus den Gattungen Cratyna Winnertz, 1867 [4 Arten], Euricrium Enderlein, 1911 [8 Arten], Metangela Rübsaamen, 1894 [4 Arten], Pseudosciara Schiner, 1866 [21 Arten] und Sciara Meigen, 1803 [3 Arten]. Die Arten werden redeskribiert und abgebildet. 63 Spezies wurden neu kombiniert und 4 Namen als neue Synonyma auf dem Artniveau erkannt: Plastosciara barretoi Lane, 1960 als neues Synonym zu Cratyna boracensis (Lane, 1960); Plastosciara downsi Lane, 1960 als neues Synonym zu Cratyna cucarisi (Lane, 1960), Euricrium fulgescens Enderlein, 1911 als neues Synonym zu Euricrium ruebsaameni (Enderlein, 1911); Pseudosciara aitkeni Lane, 1959 als neues Synonym zu Pseudosciara forceps (Pettey, 1918). Zusätzlich werden 3 synonymisierte Namen restituiert [Metangela spinata Lane, 1955 restit., Pseudosciara ribeiroi (Lane, 1955) restit., Trichomegalosphys Enderlein, 1911 restit.] und 2 präokkupierte Namen wurden ersetzt: Pseudos. willistoni Menzel nom. nov. für Sciara concinna Williston, 1896 [praeocc.] und Pseudos. helleri Menzel nom. nov. für Sciara debilis Williston, 1896 [praeocc.]. Außerdem ergab sich die Notwendigkeit, für Pseudosciara willistoni Menzel nom. nov. einen Lectotypus zu designieren sowie für Pseudosciara muricata (Lengersdorf, 1926), Pseudosciara thoracica (Lengersdorf, 1930) und Metangela bicolorata (Lengersdorf, 1930) Neotypen festzulegen. Für 2 Arten werden die bisher unbekannten Männchen ergänzend beschrieben [Euricrium varians (Lane), Pseudosciara humeropicta (Lengersdorf)]. Die Namen der Gattungsgruppe Zygomma Enderlein, 1911 [praeocc.], Mapiria Edwards, 1934 und Muhabbetiola Koçak, 2009 sind jüngere Synonyme von Euricrium Enderlein, 1911. Die Gattung Pseudosciara Schiner wird in die beiden Subgenera Pseudosciara s. str. und Pseudosciarella subgen. nov. unterteilt. Die Genera Apelmocreagris Enderlein, 1911, Trichomegalosphys Enderlein, 1911 und Trichosia Winnertz, 1867 sind nach dieser Revision in der neotropischen Region nicht vertreten. Diese 3 Namen müssen aus dem Katalog der neotropischen Sciaridae gestrichen werden. Die Gattung Pseudozygoneura Steffan, 1969 ist ebenfalls ein Synonym zu Cratyna Winnertz. Alle 41 von Hippa et al. (1998) beschriebenen Pseudozygoneura-Arten werden deshalb in das Subgenus Cratyna s. str. kombiniert.
