USA : Florida : Broward County : Port Everglades , 30.i.2013 . Acacia farnesiana (Stephen Beidler) ( FSCA # E2013-638 ) ( FSCA , dry and slide mounted) ; additional specimens from Collier , Hillsborough , Lee Monroe , and Polk counties ( FSCA , dry and slide mounted) . Diagnosis. This species is one of two species in which the inner lobe of the paramere is modified into a black spine. In H. flexuosa , the spine is hidden in lateral view. Females, with short, truncate terminalia, cannot be separated from those of H. mimosae Crawford. Distribution. Neotropics ( Costa Rica , El Salvador , Mexico ), western USA ( Arizona , California ) ( Ouvrard 2020 ), USA (FL) ( Halbert 2013 ). Host plants. Acacia farnesiana (L.) Willd. ( Fabaceae ). Comments. Heteropsylla flexuosa was found established at Port Everglades, FL in late January 2013 by DPI inspector Stephen Beidler on Acacia farnesiana (FSCA# E2013-522). This species is similar to Heteropsylla mimosae , which has been in Florida since 1983 (see below). Recent examination of populations from both sites reveals consistent differences in the male terminalia. Unlike H. mimosae , H. flexuosa has spread to Hillsborough (FSCA# E2013-2620), Monroe (FSCA# 2018-5926), Lee (FSCA# E2015-3444), Collier (FSCA# E2016-221), and Polk (FSCA# E2014-7038) counties. The Polk County record is from a suction trap.
