HISTERID BEETLES (COLEOPTERA: HISTERIDAE) OF LOUISIANA

Updated 13 August 2007
The list of 92 species of Louisiana Histeridae presented below is the result of sorting and identifying specimens preserved in the Louisiana State Arthropod Museum (LSAM), Baton Rouge, LA, a literature search, and screening of several North American beetle collections for records (see list below). It represents the first systematic faunistic inventory for this family undertaken in Louisiana. Most of the collecting activities were concentrated in several localities in a small number of Parishes, so this list will undoubtedly grow as additional records accumulate. The literature search was not exhaustive, and only recent revisions were checked for state records. Additional records can also be expected as additional collections elsewhere are searched. This version contains links to photomontages of many species, linked to "dorsal" and "ventral" following the name. Use the "back" button to toggle list and photos.
As this list has been originally developed as an internet document, it will be regularly edited and updated. Several projects, both formal and informal, which involve at least some collecting of the Histeridae in Louisiana, are currently under way. I invite any interested and/or informed person to contribute to our database. Detailed information on Louisiana histerids (localities, dates, collecting methods etc.) is available from the author upon the request.
Nomenclature follows Mazur (1997). All the taxonomic categories (subfamilies, tribes, genera, subgenera, and species) are listed alphabetically. Information on institutional deposition is given parenthetically after each Parish name. Absence of this information indicates that all specimens for that Parish record are deposited in the LSAM. Institutional abbreviations are:

Note: In strict sense, the species was not recorded in East Carrol Parish. LSAM has a specimen from Pittman Island, Issaguena Co., MS. But, it seems reasonable to consider this record as East Carrol Parish record as Pittman Island is almost completely surrounded by Louisiana territory.

Distribution: West Feliciana Parish
Note: Tentative identification of this specie is A. relictus (Marseul, 1870). It is based on its external similarity to Palearctic species A. corvinus (Germar), which was reported for North America in XIX century, the record subsequently attributed to A. relictus (see synonymic notes in Mazur 1997).

Note: For East Carrol Parish record (1 specimen) – see Note under Phelister vernus. Unfortunately, taxonomy and nomenclature in the Platysomatini always has been unstable, and several major rearrangements were made as recently as in the 1980-90s (see Bousquet & Laplante 1999, Mazur 1984, 1997, 1999). I’m following the most recent nomenclature and generic/subgeneric status of Bousquet & Laplante (1999) and Mazur (1999).

Synonyms: Saprinus simulatus Blatchley, 1910
Euspilotus assimilis: Wenzel, 1939
Distribution: Grant, West Feliciana Parishes
Note: Identification is somewhat doubtful and is based on comparison of external morphology of the LA specimen with specimens in the CNC matched with Blatchley’s type by S. LaPlante
Euspilotus (Hesperosaprinus) sp. 1
Distribution: Bossier, Calcasieu (CNC), Concordia (CNC), East Baton Rouge, East Feliciana, Grant, Natchitoches, Pointe Coupee, Rapides (CNC), St. Landry, St. Tammany, Webster, Winn (LSUS), West Feliciana Parishes
Note: Systematics and nomenclature for the North American Euspilotus species is poorly developed, and there are several undescribed species and tentative synonyms in the genus. As a result, identification of many species is problematic resulting in unnamed numbered species. Tentative identification for this species is E. auctus (Schmidt, 1890), however, exact relations of superficially similar SE US specimens with Mexican E. auctus and some other Central American specimens remain unresolved.
Euspilotus (Hesperosaprinus) sp. 2
Distribution: West Feliciana, Winn (LSUS) Parishes
Note: Tentative identification for this species is E. conformis (J. E. LeConte, 1890).
Euspilotus (Neosaprinus) sp.
Distribution: Caddo Parish
Geomysaprinus (s.str.) goffi Ross, 1944
Distribution: Natchitoches Parish
Geomysaprinus (Priscosaprinus) formicus (Hinton, 1935)
Synonym: Saprinus formicus Hinton, 1935
Distribution: Bienville (FMNH), Rapides (Moser 1963) Parishes
Note: The situation with the systematics of Geomysaprinus (Priscosaprinus) is the same as with Euspilotus [see Note under Euspilotus (Hesperosaprinus) sp.]. Identification of this species is somewhat doubtful due to incomplete knowledge of the genus and distributional disjunction between the type locality, Tejupilco in SC Mexico, and Louisiana. Specimens from Rapides Parish were originally reported as "a new species" of Saprinus "being described by R. L. Wenzel" (Moser 1963), but they probably belong to G. formicus. I did not see any Rapides Parish specimens during my visit to the FMNH in 1998, but did see there specimens from several localities in Bienville Parish.
