List of more than 3,500 beetle species collected in Latimer Co., OK (76 pg. PDF)

Ed Riley compiled the original version of this list during the years 2000-2002 as Karl Heinz Stephan (1931-2005) donated sections of his beetle collection to the TAMUIC in College Station, Texas.

In 2014, Mike Quinn began updating the taxa into the list's present form. Most of his changes are denoted within brackets in the notes column. The majority of the list has been proofread, but numerous spelling and taxonomic errors no doubt remain, particularly in the latter section of the list.

Some 3,516 species, including morpho-species, in 99 beetle families are listed. Due to the large number of specimens only determined to genus, the actual number of species collected is possibly significantly greater.

Riley (pers. comm., 2014) cautions that this list should be considered a "quick and dirty" list at best. Its primary purpose was to document the number of "species" and specimens donated by Karl to the TAMUIC.

Note that 'number of specimens' columns are a significant under-count of Stephan's collecting efforts in Latimer County as he collected many thousand more specimens that were provided to the Eastern Oklahoma State College, Florida State Collection of Arthropods, the Field Museum, and to the Sam Noble Museum.

Some 50 species carabids and buprestids are apparent new state records denoted by "[NSR?]" per Bousquet (2012) (1) and Nelson et al. (2008) (2) respectively. Stephan's collecting efforts were certainly responsible for numerous prior new state records. Amazingly, Stephan's Latimer Co. list exceeds (by 600 spp!) the Checklist of the Coleoptera of Oklahoma compiled by Dr. Don Arnold, Retired, Department of Entomology and Plant Pathology, Oklahoma State University, Stillwater.

Mordellids were inexplicable left off the list compiled by TAMU, so Dr. Katrina Menard at the Sam Noble Museum provided a list of 23 mordellid taxa collected by KHS during the summer of 2002 in a flight intercept trap that were donated to the Sam Noble Museum.

Homage to Karl Heinz Stephan (1931-2005)

"His 30 years in rural Latimer County were spent collecting, which has made this county one of the most thoroughly documented pieces of real estate in the U.S. for beetle diversity. At last count, he had recorded 3,516 species based on ~52,500 specimens that comprised one of his last donations to the Texas A&M Insect Collection." (Carlton et al. 2005)

Google Map of Latimer County indicating surrounding ecoregions

Latimer County, when compared to the rest of Oklahoma, has a higher annual precipitation (~44-50 inches), higher annual temperature (with correspondingly low annual snowfall), and the most significant changes in elevation than elsewhere in OK. Latimer Co. also has relatively low human population. These abiotic factors probably contribute to Latimer County's significant coleopteran entomofauna.

Potential new caraboid records for Oklahoma!
Below is a subset of caraboid taxa collected by Karl Stephan over several years from Latimer Co (OK) that specifically were not given Oklahoma status in the recent catalogue by Bousquet (2012). Spelling corrections and current nomenclature are applied to Stephan's original list. Before claiming new state records for Oklahoma, we need to assess our collective confidence in the various species identifications. For example, did outside carabid experts provide any of the difficult determinations among the Loxandrus specimens? I do not know if Karl Stephan had special expertise in ground beetle identification. All or most of the easier identifications will likely turn out to be new state records. Note that the original inventory cites "240 unidentified Carabidae" - a number which may or may not include the several instances of unidentified species that were assigned to various genera. All specimens were deposited at TAMUIC. This early analysis (with some comments in parentheses below) is by Peter W. Messer 3/31/2014. Feedback is welcome.

Update 4/5/2014: Accepted new caraboid records for Oklahoma.
Below is a revised subset of caraboid taxa collected by Karl Stephan for 30 years from Latimer Co. (eastern OK) that specifically were not given Oklahoma status by Bousquet (2012) in his recent catalogue (1). Spelling corrections and current nomenclature are applied to Stephan's original list. I thank Mike Quinn for catching several errors that had crept into my original list posted above. At this time my arbitrary criteria for accepting a new record is whether that species was recorded in a state adjacent to OK, including near corner LA. Names in bold print have known ranges significantly farther from OK and therefore they are tentatively not added to the registry/forum for new caraboid records (2). I welcome opinions and corrections for a future update.

this is downright humbling.

carabid records
Matt Gimmel was working on a checklist of OK carabids off and on for a few years, so he might have some insights. I will alert him.

 
Current complete caraboid checklist for OK ---
I presume you got the complete OK check list that I generated from the catalogue by Bousquet (2012) and recently sent to Mike's circle which included your name. You may pass it on to interested parties. The current checklist does not yet include Stephan's contributions.
