Freysuila dugesii Aleman, 1887

Materials examined. USA: Florida: Broward County: Hollywood, vii.1995, x.1995, Haematoxylum campechianum (K. Vanyo) ( FSCA #s E1995-2997, 4174). Miami-Dade County: Miami, 11.vii.1995, Caesalpinia (Olga Garcia) ( FSCA # E2006-7814) ( FSCA, dry and slide mounted, ethanol).

Diagnosis. The only other psyllid on H. campechianum is Heteropsylla fusca Crawford, 1914 . Freysuila dugesii can be distinguished from H. fusca by its short conical genal processes (H. fusca lacks genal processes) and by the prominent black tubercle on the metapostnotum.

Distribution. Mexico ( Hodkinson and White 1981), USA (CA) ( Percy et al. 2012), USA (FL) ( Halbert 1995).

Host plants. Caesalpinia cacalaco Humb. & Bonpl. , Haematoxylum campechianum L. ( Fabaceae ).

Comments. Freysuila dugesii was found for the first time in Florida by DPI inspector Karolyn Vanyo on Haematoxylum campechianum L. ( Fabaceae ) in July 1995 and recollected in October of the same year (FSCA#s E1995-2997, 4174). The infestation was severe, but only a single dooryard tree was infested. The infestation evidently was eradicated when the single infested tree was removed. This species turned up again in 2006 in Miami-Dade County on Caesalpinia (FSCA# E2006-7814). Once again, a single plant was infested heavily.

Materials examined. See Serbina et al. (2015) and Serbina and Burckhardt (2017). Brazil: São Paulo: Matão suction trap collections.

Comments. This genus does not occur in Florida, but at least two species are pests of Solanaceae in South America ( Serbina and Burckhardt 2017).
