Diagnosis. Flagellomere ascoids usually with long basally directed branch or at least rudimentary (as in Ps. lanei (Barretto & Coutinho, 1941), Ps. guatemalensis (Porter & Young, 1986), and Ps. punctigeniculata (Floch & Abonnenc, 1944)); hindleg with first tarsomere longer than the length of other tarsomeres combined. Male: gonocoxite without perennial setae; gonostylus with 4 spiniform setae and no preapical fine seta. Female: cibarium with 4 to 8 horizontal teeth, vertical teeth variable, but always present, complete arch, and prominent pigmented patch (Young & Duncan 1994, Galati 2003).

Remarks. Three subgenera of genus Psathyromyia are recognized by Galati (1995, 2003): Ps. (Forattiniella) Vargas, 1978, Ps. ( Xiphomyia) Artemiev, 1991, and Ps. (Psathyromyia) sensu stricto . Seven species belonging to the three subgenera have been recorded in Mexico; six species were found in this work.
