Heteropsylla flexuosa Muddiman, Hodkinson and Hollis, 1992


Heteropsylla flexuosa Muddiman, Hodkinson and Hollis, 1992  

Materials examined. USA: Florida: Broward County: Port Everglades , 30.i.2013. Acacia farnesiana (Stephen Beidler)   ( FSCA # E2013-638 View Materials ) ( 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.
