Additional distribution information. This species was first recognized in Florida when it was found on Bursera simaruba in Miami by DPI Inspector Gwen Myres on 7.viii.2003 ( FSCA # E2003-3561). More collections were made from the same location on 28.viii.2003 ( FSCA # E2003-3841), 22.ix.2003 ( FSCA # E2003-4610), 17.xii.2003 ( FSCA # E2003-6519), 5.i.2004 ( FSCA # E2004-135). Collections were made at another location in Miami on 24.xii.2003 ( FSCA # E2003-6674) and on 6.i.2004 on B . simaruba by DPI inspector Duraid I. Hanna ( FSCA # E2004-130). A specimen, apparently this species, was collected in a blacklight trap on Plantation Key (Monroe County) by H.V. Weems on 1.i.1967.

Distribution. USA: Florida: Collier, Miami-Dade and Monroe counties.

Host plants. Bursera simaruba (L.) Sarg. ( Burseraceae ).

Derivation of name. Named after its host, Bursera simaruba , locally called gumbo-limbo. Applied as a noun in apposition.

Comments. Pseudophacopteron is a pantropical genus previously not recorded from North America. In the Neotropics, the genus is known from five species from Panama ( Brown and Hodkinson 1988) and two species from Brazil ( Malenovský et al. 2015). Pseudophacopteron gumbolimbo resembles P . antennatum Brown and Hodkinson, 1988, in the forewing pattern and the shape of the paramere and the female terminalia but differs in the subequal terminal antennal setae, the apically more angular forewings, and in the shape of the apical dilation of the aedeagus, which is relatively narrower and only slightly curved ventrally, hardly hooked.

The species probably is native to Florida. Immatures are found on undersides of new leaves, causing no damage other than an occasional indistinct yellow spot. Adults have been collected in the suction trap in Miami- Dade County in all months except August and September.
