Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published on any non- marine arthropod. Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. Insecta Mundi publishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources, including the Zoological Record and CAB Abstracts. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an individual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology. Guidelines and requirements for the preparation of manuscripts are available on the Insecta Mundi website at http://centerforsystematicentomology.org/insectamundi/

New state records of lady beetles (Coleoptera: Coccinellidae: Coccinellinae) from Missouri and Mississippi, USA

Abstract. New state records for three species of lady beetles (Coleoptera: Coccinellidae: Coccinellinae) are re- ported from two states in the south-central USA. Hyperaspis bolteri LeConte and Exochomus childreni guexi LeConte are newly reported for the state of Missouri, and Hyperaspis connectens (Thunberg) is newly reported for the state of Mississippi.

Introduction Reporting new faunal records for specific areas or governmentally formulated regions such as states or provinces enhances the knowledge of species’ geographical ranges and regional biodiversity (McCafferty 2000; Taylor 2010). New records may fill in gaps and confirm hypotheses about a species’ geographic range and they may also provide knowledge about a new or unexpected geographic distribution of a particular species. Reported here are new state records for three species of lady beetles (Coleoptera: Coccinellidae: Coccinellinae) from the states of Missouri and Mississippi, USA.

Materials and Methods New state records of lady beetles were found among undetermined adult specimens of lady beetles in the University of New Hampshire Insect Collection (UNHC), Durham, New Hampshire, USA. Label information was reported verbatim with no edits or attempts at interpretation of label data. Specimens discussed in this paper were identified using keys in Gordon (1985). A revised classification of the Coc- cinellidae (Seago et al. 2011) was used for nomenclatural purposes. Pinned specimens of beetles that represent the primary state records in this paper were designated as voucher specimens.

Results

Hyperaspis bolteri LeConte, 1880 Missouri (new state record), 1.5 mi W Kingdom City, Callaway Co., Tucker Prairie, Dec. 2-3, 1974, 1 ♂, 1♀. No prey or specific habitat was listed. These specimens (Figure 1) constitute a new state record for Missouri. A search of the Symbiota Collections of Arthropods Network (SCAN) found a later collection record of H. bolteri recorded at BugGuide.net with similar collection data: Missouri, Callaway, 38.835964°, −91.92409°, 2012-05-27 (https://bugguide.net/node/view/757506).

Hyperaspis connectens (Thunberg, 1808) Mississippi (new state record), Picayune, 7-28-1977, L. Ferreira, 1 ♀. No prey or habitat data were recorded with the specimen (Figure 2). 2 • Insecta Mundi 0745, January 2020 Hesler

Exochomus childreni guexi LeConte, 1852 Missouri (new state record), Centerville, June 11, 1977, S. C. Thewke, 2 ♀♀. No prey or habitat data were included with the collection data. Each specimen represented a different one of the two major elytral color patterns (Figure 3) known for E. childreni guexi (Gordon 1985).

Discussion New records reported here for the three species of lady beetles contribute fundamental knowledge about their geographic distributions and the composition of insect communities in south-central USA. The new state records for Hyperaspis bolteri and H. connectens essentially fill in gaps associated with the known geographic distribution for these two species. The new state record from Missouri was expected, given that Gordon (1985) listed H. bolteri from the states of Indiana, Illinois, and Kansas within the USA. Similarly, the new state record of H. connectens from southern Mississippi was expected, given that its collection site has a similar latitude to this species’ known geographic distribution in southern Louisiana and northern Florida in the United States (Gordon 1985). Prey and other bionomic aspects of many species of Hyperaspis are poorly known (Majka and Robinson 2009), and additional sampling with an emphasis on prey and habitat associations of H. bolteri and H. connectens would be useful. The previously known distribution of Exochomus childreni guexi extended from Louisiana through southern Texas (Gordon 1985). Thus, the new state record of E. childreni guexi for Missouri increases its known distribution considerably northward. Members of Exochomus prey on aphids (Gordon 1985), and it would be informative to determine if new prey records for this lady beetle may be associated with its northern distribution. Hesler and Kieckhefer (2008) hypothesized that processing unsorted and undetermined coccinellid specimens will reveal new information about the geographic distributions of lady beetle species. The new state records reported here support that hypothesis and may serve as impetus for further sampling of lady beetles and the treatment of unprocessed material.
