A preliminary checklist of Calpini is provided, incorporating corrections and changes to publication dates and nomenclature as presented in the checklists of Poole (1989), Fibiger and Lafontaine (2005), and Holloway (2005). Culasta Moore is removed from synonymy with Calyptra Ochsenheimer. Eudocima talboti (Prout) and Graphigona antica Walker are placed in synonymy with E. cajeta (Cramer) and G. regina (Guenée), respectively. Africalpe Krüger, Ferenta Walker, Gonodonta Hübner, Graphigona Walker, Oraesia Guenée, and Tetrisia Walker, are added to the tribe based on shared characters. The genera Cecharismena Möschler, Goniapteryx Perty, Pharga Walker, Phyprosopus Grote, Psammathodoxa Dyar, and Radara Walker are removed and considered incertae sedis. Hemiceratoides and Phyllodes are not considered to be members of Calpini.
In the eastern United States, the genus Cotinis Burmeister previously contained only C. nitida (L.), the common economic pest known as the "Green June Beetle". A new species from the Florida Keys, Cotinis aliena, is here described and illustrated. A checklist is provided for the genus, which includes 27 valid New World species, and 44 synonyms.
A list of all liverworts and mosses reported from the Maltese Islands with references has been compiled from the literature, which includes 23 species of liverworts and hornworts as well as 96 taxa of mosses. The list is completed by the results of a bryological fieldtrip in March 2008. During this trip, 14 species of liverworts and 40 species of mosses were collected, of which Cephaloziella baumgartneri, Didymodon luridus, Fissidens gracilifolius, Fossombronia echinata, Funaria pulchella, Riccia cavernosa and Weissia fallax are new to Malta. This raises the number of species known from the Maltese Islands to 23 horn- and liverworts and 100 mosses.
The bee fauna of the Greater Puerto Rico area was studied. A review of the previous relevant studies is presented. An annotated catalog and information about the origin and distributional patterns are also provided. Thirty-nine species of bees occur in Puerto Rico and adjacent islands. This fauna is composed of four elements: exclusive Puerto Rican endemics (26.5%); Antillean endemics occurring on multiple islands (76.5%); continental species that have also colonized the Antilles (23.5%); and species introduced through human activity (12.8%). The bee fauna was both low in its diversity and showed the highest level of disharmony in relation to other faunas of the Greater Antilles. A lectotype is here designated for Agapostemon krugii Wolcott, 1936.
The Tetragonoderus (Peronoscelis) quadriguttatus assemblage is a postulated monophyletic part of the intersectus complex. This assemblage is characterized against a background that includes review of a classification of the genus and comparison, in the form of a key, to other unrelated Western Hemisphere genera that share elongate tibial spurs with Tetragonoderus Dejean. The principal, easily observed feature that unites the three members (T. laevigatus Chaudoir, 1876; T. deuvei, new species (type locality: Cuijaba, Mato Grosso, Brazil), and T. quadriguttatus Dejean) of the quadriguttatus assemblage is the four-spotted elytra (two spots per elytron). These species are treated in detail, including key, synonymy (as required), comparisons, description (external and male genitalic features), habitat (if known), locality data, and geographical range map. Also, T. subfasciatus Putzeys, 1846, the elytral color pattern of whose members may be confused with the spotted pattern of the quadriguttatus assemblage, is treated similarly. The following new synonymies were established: T. quadriguttatus Dejean 1829 = T. columbicus Steinheil 1875 = T. lacordairei Chaudoir 1876 = T. tetragrammus Chaudoir 1876; and T. laevigatus Chaudoir 1876 = T. chaudoiri Liebke 1928 (replacement name for the junior homonym, T. unicolor Chaudoir, 1876). Lectotypes are designated for T. unicolor Chaudoir, T. lacordairei Chaudoir, and T. subfasciatus Putzeys. A neotype is designated for T. quadriguttatus Dejean. New distribution records in the West Indies for T. quadriguttatus are recorded for the islands of Grand Cayman, Jamaica and Hispaniola. These records may be the result of recent natural overseas dispersal from northern South America, or they may be the result of human-mediated accidental introduction, or a combination of both. The southern Floridian (Nearctic) records for T. laevigatus probably represent a recent accidental introduction through commerce, followed by dispersal through flights of adults.
