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 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/ Chief Editor: David Plotkin, [email protected] Assistant Editor: Paul E.

Gordon Northern Plains Entomology PO Box 65 Willow City, ND 58384, USA [email protected] Abstract. Genera of Cryptognathini (Coleoptera: Coccinellidae) are discussed and a key to all recognized genera is provided. Cryptognatha is revised, and species of this genus are keyed. New species, authored by González and Hanley, are Cryptognatha pam, C. kellie, C. hannah, C. whitney, C. karla, C. celia, C. shelia, C. gayle, C. della and C. vicki. The following new synonymies are proposed: Cryp- tognatha simillima Sicard = Cryptognatha gemellata Mulsant, Cryptognatha fryii Crotch = Cryptognatha pudi- bunda Mulsant, Cryptognatha bryanti Brèthes = Cryptognatha pudibunda Mulsant. Lectotypes are here desig- nated for Cryptognatha amicta Gorham, C. weisei Brèthes, C. pudibunda Mulsant and C. fryii Crotch. Key words. Systematics; keys; illustrations; taxonomy; new species. Introduction Cryptognathini are not particularly distinctive among coccinellid tribes because they lack a single obvious identifying character. A combination of characters renders this tribe recognizable; among these are five visible abdominal ventrites, a glabrous body, the head at least partially concealed by the pro- sternum in some genera, a short, compact antenna, and a securiform maxillary palpus. It is a primarily Neotropical tribe, without apparent Old World relatives, and is known from Mexico, Central America, and South America. The following is a revision of Cryptognatha containing comments on Cryptognathini as a whole. Following publications will be treatments of all remaining genera without tribal comments. Nomenclatural history Mulsant (1850) first described a member of this tribe as Cryptognatha auriculata, along with two other species, and described the genera Oeneis and Pentilia. Crotch (1874) included Cryptognatha Mul- sant and Pentilia Mulsant in his subfamily Chilocorides. Korschefsky (1931) treated Oeneis Mulsant as a valid genus, placing it and Cryptognatha in the tribe Oeneini, and placing Pentilia in Pentiliini. Chapin (1940) pointed out that Oeneis was a preoccupied name but did not propose a replacement name. Blackwelder (1945) considered Oeneis a synonym of Cryptognatha in the tribe Oeneini and placed all genera other than Cryptognatha in other tribes. Chapin (1955) proposed Dargo as a new name for the preoccupied Oeneis and stated that the type species of Oeneis, O. nigrans Mulsant, might belong in what is now known as Delphastus Casey, a member of the Serangiini. 2 • INSECTA MUNDI 0714, June 2019 GONZÁLEZ ET AL. Gordon (1971) recognized Cryptognathini as having priority over the tribes Oeneiini and Pentiliini, and proposed the genus Delphastopis (as a replacement for Oeneis, Cryptognatha, Pentilia and the new genus Curticornis). A specimen labeled O. nigrans Mulsant from Brazil (type locality) in the Korschefsky collection has been dissected and is an Oeneis, as is another Brazilian specimen labeled as O. nigrans. Dissection of the type specimen of Delphastus amazonica shows it is congeneric with Oeneis, thus mak- ing Delphastopis available to replace the preoccupied Oeneis and making Dargo Chapin unnecessary. However, Calloeneis Grote, 1873 is the earliest replacement name for Oeneis, as pointed out by Belicek (1976), and is used herein. This tribal study is split into individual publications, each treating a different genus. All types were examined regardless of supposed generic assignments, because authors subsequent to Mulsant (1850) often assigned specific taxa to incorrect genera, either by mistake or due to differing generic concepts. Materials and Methods Biology. Prey records are rare for members of Cryptognathini. Label data for examples of Calloeneis amazonica list “diaspine scale” as prey. Label data for Calloeneis bennetti list Aspidiotus destructor Signoret as prey. Other label data list Pinnaspis aspidistrae and Selenaspidius articulatus (Diaspididae) for Cryptognatha auriculata, Aspidiotus destructor and Pinnaspis aspidistrae (Diaspididae) for Pentilia bernardette,
