Dytiscidae

Acilius confusus Bergsten. A male and female were collected in Jackson Co., Little Dry Creek near Alford, 19-xi-1984, leg. W.R. Karsteter. This species, previously confused with A. fraternus (Harris) and A. semisulcatus Aubé , was recently described in Bergsten and Miller (2005). Their southernmost record was from South Carolina; this is the first state record for Florida and the southernmost record for this species.

Dytiscus carolinus Aubé. A single female was collected at Liberty Co., Apalachicola Bluffs and Ravines Preserve , 30.49423N 84.97740W, blacklight in sandhill habitat near ravine, 12-iv-2007, leg. D.T. Almquist; as part of the Florida Natural Areas Inventory Invertebrate Survey. This is the first record for this genus and species from Florida. This beetle was expected in Florida, since records from just across the state line in southern Alabama and Georgia are given in Roughley (1990: fig. 31).

Matus bicarinatus (Say) . Numerous males and females were studied from Santa Rosa Co., Escambia River at Molina Boat Ramp Park , UV pan trap, 14-iv-2007, leg. D. R Denson ; and Santa Rosa Co., Blackwater River hiking trail ~ 300 m. Deaton Bridge Road , UV pan trap, 13-vi-2007, leg A.K. Rasmussen. These are the first records for this species from Florida ; thus three of the four North American species of Matus are now recorded from Florida .
