Histerid Beetles (Coleoptera: Histeridae) of Louisiana

Updated February 2010

The list of the 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 primarily 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.

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.

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).

Hister incertus Marseul, 1825

Dorsal Ventral

Synonyms: Hister debilicinus Casey, 1924

Distribution: Cameron (LSAM and TAMU) and West Feliciana Parishes

Note: Taxonomic and distributional status of this species and a closely related H. paykulli Kirby, 1837, is not completely settled. The latter species was recently resurrected from the synonymy with H. depurator (Mazur 1997) by Bousquet and Laplante (2006). According to these authors, the species differ by slight, but consistent details of body shape and aedeagus structure. Also, their known distribution is widely allopatric: H. incertus is primarily south-eastern species known from Florida to Texas and Pennsylvania and New York, while H. paykulli is known only from Canadian Prairie region (Mazur 1997, Bousquet & Laplante 2006). Unfortunately, Bousquet and Laplante (2006) did not provide comparative illustrations ofH. incertus, and I was not able to study specimens of true H. paykulli, so it is impossible for me to be sure about the differences observed in the studied specimens of H. incertus in a broad sense. Most of male specimens studied (from Florida to Texas and Oklahoma, including the male from Cameron Parish) have similarly structured aedeagi, which are consistently shorter, more robust and with broader lateral processes than illustrated forH. kirbyi. On the other side, the aedeagus of the single male from W Feliciana Parish corresponds well with the illustration for H. kirbyi in Bousquet and Laplante (2006). However, at the current level of knowledge and my expertise, I m not confident to call it H. kirbyi and list specimens from both localities under H. incertus.

Margarinotus (Promethister) sp.

Dorsal Ventral

Note: Most probably this is an undescribed species. One male was collected during March 2001 at Red Bluff Campground in Kisatchie National Forest. Subsequently, several specimens from from Pulaski Co., AR, Sabine Co., TX, and Latimer Co., OK were studied. All specimens were collected using flight intercept traps. Some additional material needs to be studied to be sure of the status of this species before a description is published.

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, sometimes not consistent rearrangements were made as recently as in the 1980-90s (see Bousquet & Laplante 1999, Mazur 1984, 1997, 1999). I'm following the recent nomenclature and generic/subgeneric status of Bousquet & Laplante (1999, 2006) and Mazur (1999).

Synonyms: Saprinus simulatus Blatchley, 1910

Euspilotus assimilis: Wenzel, 1939

Euspilotus (Hesperosaprinus) sp. 1

Dorsal Ventral

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

Dorsal Ventral

Distribution: West Feliciana, Winn (LSUS) Parishes

Note: Tentative identification for this species is E. conformis (J. E. LeConte, 1890).

Geomysaprinus (Priscosaprinus) formicus (Hinton, 1935)

Dorsal Ventral

Synonym: Saprinus formicus Hinton, 1935

Distribution: Bienville (FMNH), Natchitoches , Rapides (Moser 1963) Parishes

Note: The situation with the systematicsof Geomysaprinus (Priscosaprinus) is the same as with Euspilotus [see Note under Euspilotus(Hesperosaprinus) sp.]. Identification of this species as G. formicus 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.
