We present a review of Dendrocephalus (Dendrocephalinus) with an updated diagnosis for the subgenus and a key to all known species. We provide new records of Dendrocephalus alachua, which was previously supposed to be extinct, and we describe a new species, Dendrocephalus proeliator sp. nov., which is separated from all other species based on the form of the male frontal appendage. Dendrocephalus proeliator sp. nov. appears to be morphologically intermediate between D. alachua and D. lithaca. In addition, we provide conservation assessments for all four species in the subgenus, according to IUCN Red List standards. We also report for two species the first known examples of direct male-male agonistic behaviour and competition for access to areas frequented by receptive females.
Ptyoiulus Cook 1895, the dominant parajulid diplopod genus in the eastern United States (US), comprises two species – P. impressus (Say 1821), with a slanted, fl ared, circumferentially entire, and marginally serrate apical calyx on the anterior gonopod coxal process, and P. montanus (Cope 1869), n. comb., with a smooth, upright, cupulate calyx that is open caudad and coaxial with the process’ stem. The genus occupies a broad area between the Mississippi River and Atlantic Ocean extending from southern New England, Ontario, and Michigan to the Florida Panhandle and four small disjunct ones – from Montreal, Québec, to northern Vermont, along southwestern Lake Michigan in Wisconsin and Illinois; northeastern/eastcentral Arkansas, primarily in Crowley’s Ridge physiographic feature and beside the “bootheel” of Missouri; and a point locality in northeastern Louisiana just south of the Arkansas line. A male from Chester County (Co.), Pennsylvania, is designated as the neotype of Julus impressus, as is one from Durham Co., North Carolina, for J. montanus. As both species inhabit Montgomery Co., Virginia, the type locality of J. montanus, we exercise the right of first reviser, conserve the latter name, and assign it to the species with the smooth, cupulate, and coaxial calyx. We also exercise first reviser rights and assign Parajulus ectenes Bollman 1887 to this form, thereby relegating it to synonymy under Ptyoiulus montanus. Other new synonymies include Ptyoiulus georgiensis Chamberlin 1943 under P. impressus and P. coveanus Chamberlin 1943 under P. montanus. Both Ptyoiulus and P. impressus are projected for Delaware and Rhode Island and newly reported from Québec, Connecticut, District of Columbia, Maryland, Mississippi, South Carolina, Vermont, West Virginia, and Wisconsin, and the genus and species, respectively, are newly documented from Louisiana and Arkansas; P. montanus is newly cited from Alabama, Arkansas, Georgia, Mississippi, and South Carolina. Ptyoiulus impressus occupies every state except perhaps Louisiana and is the only species in areas that were inundated during the Cretaceous and glaciated during the Pleistocene; by contrast, P. montanus inhabits a relatively narrow east/west transect through the center of the generic range. Their distribution patterns suggest an old species, montanus, being actively displaced by the younger and more successful impressus. The decurvature of the epiproct in uroblaniulinines appears to increase with age and developmental stage. A key is presented to parajulid familygroup taxa in the US and Canada east of the Rocky Mountains.
Past concepts and synonymies of Anadenobolus monilicornis (Porat, 1876) (Spirobolida: Rhinocricidae), including the implied synonymy of Rhinocricus ectus Chamberlin, 1920, are consolidated into a formal account with the fi rst illustrations of the holotype. Prior to 1492, A. monilicornis was probably indigenous to an unknown number of southern Antillean islands, but through modern commerce, man has introduced it to Florida, Bermuda, Barbados, the Cayman Islands, and Jamaica, and probably repeatedly (re)introduced conspecifi c material to all the Lesser Antilles, resulting in subcontinuous gene pool mixing and reticulate evolution. A broad species concept is necessary to encompass the multitudinous variants, some of which have been recognized as species; only one true Caribbean species of Anadenobolus Silvestri, 1897, may exist, for which arboreus (Saussure, 1859) is the oldest name. The distribution of A. monilicornis presently extends from Bermuda and southern coastal Florida through the Greater and Lesser Antilles (excepting Cuba) to eastern coastal Venezuela and central Suriname, with outlier populations in Jamaica, the Cayman Islands, and Tampa Bay and the eastern Floridian panhandle; excepting Barbados, the indigenous range may have extended from Hispaniola through the same area. Introductions into Manitoba, Canada, and North Carolina, USA, have not yielded viable populations. Localities are newly recorded from St. Thomas, US Virgin Islands.
The known range of Oxybleptes meridionalis Smetana (Coleoptera: Staphylinidae) is expanded in Florida, USA, from Indian River and Manatee counties to now include Brevard, Highlands, Orange, Seminole and Volusia. Oxybleptes davisi (Notman) is confi rmed to exist in Florida, with records from Leon, Liberty and Wakulla counties in the Panhandle, and Orange County in central Florida. Lissohypnus texanus Casey is newly reported from Florida. A new species, Lissohypnus fullertoni, is described from Florida. Diochus schaumii Kraatz reverts to this original spelling; its widespread form in Florida is identical to that in the northeastern USA.
New North American records of Pyraloidea (Lepidoptera: Crambidae, Pyralidae) from southern Florida
(2014)
We report six new North American records, one new state record, and one rare record of pyraloid moths from southern Florida, together with diagnostic characters for all taxa. We transfer Ennomosia Amsel from Spilomelinae to Glaphyriinae, Cangetta micralis (Hampson) n. comb. from Deuterophysa Warren, and Microthyris lelex (Cramer) n. comb. from Cyclocena Möschler. We revise Pseudocabotia Blanchard and Knudson rev. stat. to a subgenus of Ancylosis Zeller, with its type species A. (P.) balconiensis (Blanchard and Knudson) n. comb., and discuss the classifi cation of Cabotia Ragonot as a subgenus of Ancylosis.
The mirine plant bug Tropidosteptes forestierae, new species (Hemiptera: Miridae) is described from
Collier County, Florida, where it was found causing serious injury to an extensive ornamental hedge of Florida swampprivet, Forestiera segregata (Jacq.) Krug and Urb. (Oleaceae). Adult male and female, fifth instar, and egg are described. Color images of the adults, nymph, egg, and injury; scanning photomicrographs of selected adult structures; and illustrations of male genitalia are provided. A key to help distinguish the 16 species of Tropidosteptes known to occur in the southeastern United States is given.
We provide new records of biting and predaceous midges (Diptera: Ceratopogonidae) from Florida, including the first documented United States records of Atrichopogon (Atrichopogon) caribbeanus Ewen, Dasyhelea griseola Wirth, D. scissurae Macfie, and Brachypogon (Brachypogon) woodruffi Spinelli and Grogan. Atrichopogon (Meloehelea) downesi Wirth, Forcipomyia (Thyridomyia) monilicornis (Coquillett), F. (T.) nodosa Saunders, Ceratoculicoides blantoni Wirth and Ratanaworabhan, Mallochohelea albibasis (Malloch), Bezzia (Bezzia) imbifida Dow and Turner and B. (B.) mallochi Wirth are recorded for the first time from Florida. Forcipomyia (Thyridomyia) johannseni Thomsen, Bezzia (Bezzia) expolita (Coquillett), and B. (B.) pulverea (Coquillett) are deleted from the ceratopogonid fauna of Florida. Dasyhelea koenigi Delécolle and Rieb is a junior objective synonym of Dasyhelea scissurae Macfie (NEW SYNONYM). The total number of Ceratopogonidae recorded from Florida is now 249 species contained within 27 genera.
A Caribbean species of Mecidea Dallas, M. longula Stål, apparently established in south Florida, is reported from the United States for the first time. Specimens were first collected in February 2008 in a light trap operated in Miami-Dade County, Florida. Collections in that trap have continued through the present. Searches near the trap location resulted in several specimens being taken from smutgrass, Sporobolus indicus (L.), an exotic grass now established throughout much of the southeastern United States. The three North American species of Mecidea are keyed and illustrated. In addition to the Florida locality, M. longula is reported for the first time from the British Virgin Islands, St. Kitts, St. Martin, and the Turks and Caicos Islands.
