Box 141874 Gainesville, FL 32614-1874 USA http://centerforsystematicentomology.org/ 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, CAB Ab- stracts, etc. 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. Chief Editor: Paul E. Skelley, e-mail: [email protected] Head Layout Editor: Eugenio H.

Box 112710 Gainesville, FL 32611-2710 USA jmiller@fl mnh.ufl .edu Abstract. Originally described from Great Guana Cay, Exuma Islands, Bahamas, Choranthus richmondi L. Miller, was also recorded from North Andros Island. Three specimens were collected on South Andros Island, Bahamas, in March 2014, representing a new record for this island. Photographs of adults, a complete diagnosis, genitalia illustrations, and a description of the habitat, nectar sources, and potential hostplant are presented. The male genitalia are illustrated for the fi rst time. Key Words. Lucayan Archipelago, West Indies, Hesperiidae, genitalia. Introduction One of the more elusive skippers in the Bahama Islands is Choranthus richmondi, which was described by L. D. Miller (1965) in a review of the West Indian genus Choranthus Scudder. Originally described from two females from Whitepoint, Great Guana Cay and Bitter Guana Cay, Exuma Islands, Bahamas, Great Bahama Bank, this hesperiid is infrequently encountered. We have observed this species periodically on N. Andros Island but have never collected it. Based on the unusually high rain frequency in the spring of 2014 in Florida and east into the Bahamas, we visited S. Andros, Bahamas, 27 March-1 April, 2014, as part of a continuing biodiversity survey of the Lepidoptera of the Lucayan Archipelago. Despite high winds on the southern end of the island, there were a number of skippers in fl ight visiting several nectar sources. It was not until we began to process the material that we noticed these small, rather unusual skippers. We identifi ed two males and a single female of C. richmondi. The dorsal and ventral surfaces of both sexes were illustrated in Smith et al. (1994) and more recently, the female holotype is illustrated and available on the Butterfl ies of America website (Warren et al. 2014). However, there are some differences in the coloration among the illustrations and the new material. A diagnosis is presented here based on these recently collected specimens. Upon dissection of the female genitalia, additional features were noted that were not illustrated in the original description. In addi- tion, the male genitalia is illustrated and described for the fi rst time. Materials and Methods Specimens were collected on South Andros Island, Bahamas using hand nets. The specimens exam- ined, including some comparative types of other species, are deposited in the collections of the McGuire Center for Lepidoptera and Biodiversity, Florida Museum of Natural History, University of Florida, Gainesville, Florida (MGCL). In addition, wing morphology and maculation patterns of type specimens available online from the American Museum of Natural History (AMNH) and the Carnegie Museum of Natural History (CMNH), as well as published works listed in the references cited, were consulted. Identifi cations are based on the genitalia dissected with standard techniques, preserved in vials with glycerin, and compared with reference to published illustrations. 1 2 • INSECTA MUNDI 0414, April 2015 MILLER ET AL.
