New state record for Deltochilum gibbosum (Fabricius) (Coleoptera: Scarabaeidae) in Maryland, USA.

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.

ABSTRACT

This biogeographical analysis examines the historical, geological, climatic and ecological processes that have influenced the formation of the dry tropical forests (DTF) of Mesoamerica and Colombia, areas that are the setting for multiple biogeographical stories that in this case are illustrated by the patterns and evolutionary processes of Canthonini. In this study we test the hypothesis that the Canthonini fauna of dry tropical forests has a South American affinity. To this end, we compare extant species from a tract of dry tropical forest in Mexico, a second enclave in Costa Rica, four from the Caribbean region of Colombia and finally one from the north of Tolima in the Upper Magdalena River Valley, Colombia. The geomorphological characteristics of the enclaves of DTF are also compared, as are the geographical distribution and taxonomic affinities of each of the species found in these dry tropical forests. The biogeographical, historical and geological aspects of the enclaves were evaluated using a Parsimony Analysis of Endemicity (PAE), with two tropical rain forests as the outgroup: Leticia (Amazonas, Colombia) and Los Tuxtlas (Veracruz, Mexico).

This brief paper describes new Arizona state distribution records for Haroldiellus sallei (Harold) (Scarabaeidae: Aphodiinae: Aphodiini) and Phyllophaga crinita (Burmeister) (Scarabaeidae: Melolonthinae: Rhizotrogini), as well as new USA country records (Arizona and Texas, respectively) for Haroldiataenius limbatus (Bates) (Scarabaeidae: Aphodiinae: Eupariini) and Amithao erythropus (Burmeister) (Scarabaeidae: Cetoniinae: Gymnetini). Vouchers of all the species are deposited in the Hasbrouck Insect Collection at Arizona State University, Tempe, Arizona, USA.
