T y p e m a t e r i a l: Holotype (♀) labelled: " Florida: Pinellas Co., Ft. De Soto , May 8, 2016, beaten from brown/dead Sabal palmetto frond, Kyle E. Schnepp lgt. ", ( FSCA).

D e s c r i p t i o n: Female measurements (in mm): TL 2.9, EW 1.7. Dorsal integument orange-brown and black ( Fig. 1 ), setation decumbent, yellow, grey and brown. Ventral integument brown ( Fig. 2 ), setation decumbent, grey. Head shiny brown and finely punctated, covered with intermixed yellow and grey decumbent setation. Palpi light brown. Median frontal ocellus present. Eyes large with hardly visible short microseta. Antennae brown, with yellow setation, consisting of 11 antennomeres, antennal club with 3 antennomeres ( Fig. 4 ). Antennal fossa closed. Pronotum integument orange-brown with black spots and long, intermixed yellow and grey setation ( Fig. 3 ). Elytral integument in anterior 1/2 orange-brown with intermixed brown and yellow setae, and transverse narrow fascia from grey setation, apical part black with brown and yellow individual setae, much more densely and finely punctated as the pronotum. Scutellum orange-brown, small, triangular and without punctation and setation. Epipleuron short, dark brown, with some yellow decumbent setation. Metasternum coarsely punctate with grey decumbent pubescence. Abdominal visible ventrites shiny, brown, densely and coarsely punctated, with grey decumbent setation.
