Description. Adult. Female described by Ferris (1928). General body colour in males uniformly strawcoloured or ochreous. Antennal scape and pedicel light brown, segment 3 yellowish, segments 4–10 brown. Toothlike process on metanotum dark brown. Paramere, in profile, lamellar (Fig. 16, 24). Apical dilatation of distal segment of adeagus more than a third as long as segment, with large apical hook (Fig. 32).

Fifth instar immature. Antennal segments 3/4 length ratio 1.10–1.56. Forewing pad/ antennal segment 3 length ratio 2.86–3.55. Caudal plate (Fig. 47) angular posteriorly, 1.63–1.90 times as wide as long. Distance between anterior and posterior bands of caudal plate smaller than distance between posterior band and anus, measured laterally. Circumanal ring very small, transverse diameter less than 4 times as wide as pore rows on one side, consisting of 2–3 rows.

Measurements (4 specimens, in mm). Length of antennal segment 3 0.55–0.70; forewing pad length 1.95–2.05; caudal plate length 1.45–1.75.

Distribution. Reported from Venezuela (Schwarz 1899), Mexico (Ferris 1928), Cuba, Guatemala and Mexico (Tuthill 1950), United States of America (Florida) (Halbert 2003), Cuba, United States of America (Florida) (Burckhardt et al. 2011), and new for Belize and Costa Rica.

Host plant. Cedrela odorata L. (= mexicana M. Roem.).

Comments. Ferris (1928) described Freysuila cohahuayanae on the basis of a single female with immatures and a teneral male with numerous immatures from two localities in Mexico. Tuthill (1950), who examined Ferris' type material, suggested that the female belongs to M. ernstii and the male to M. schwarzi, respectively. Neither Ferris (1928) nor Tuthill (1950) did select a holotype or lectotype, respectively.
