Simons, P. and D.L. Price. 2019. New state record for Deltochilum gibbosum (Fabricius) (Coleoptera: Scarabaeidae) in Maryland, USA. The Coleopterists Bulletin, 73(1): 200-201.

Deltochilum gibbosum is reported in Alabama, Arkansas, Florida, Georgia, Illinois, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Virginia, South Carolina, Tennessee, Texas, and Mexico (Woodruff 1973; Barney 1980; Masis and Marquis 2009; Fiene et al. 2010; Evans 2014).

Here, we report the first state record of D. gibbosum in St. Mary's Co., Maryland, USA. Two specimens were captured in Point Lookout State Park, Scotland, Maryland, in a pitfall trap baited with human dung. The first author set the trap on 29 August 2017 and retrieved the beetles on 11 September 2017.

Point Lookout State Park comprises 437 hectares and is located on a peninsula on the southernmost tip of Maryland's western shore, at the confluence of the Potomac River and the Chesapeake Bay (Wilson 2016; Maryland Department of Natural Resources 2018). Point Lookout is a combination of tidal marsh and mixed pine forest with sandy and silty loam soils.
