Title: On the classification of sphecodine bees (Hymenoptera: Halictidae)
Taxonomic notes are presented for the exclusively cleptoparasitic halictine bee subtribe Sphecodina (Halictinae: Halictini). Keys are presented to the Western and Eastern Hemisphere genera of Sphecondina. In the New World fauna, the genusMelissocleptisGonçalves is considered a subgenus ofAustrosphecodesMicheners. l., and the following species transferred:Austrosphecodes(Melissocleptis)albifacies(Gibbs),A. (M.)capriciosus(Schrottky),A. (M.)coriae(Moure & Hurd),A. (M.)diablotinus(Gibbs),A. (M.)genaroi(Engel),A. (M.)nigritus(Ashmead),A. (M.)tainoi(Engel),A. (M.)variabilis(Schrottky) comb. n. A key is provided to the subgenera ofMicrosphecodesEickwort & Stages. l., withTrichosphecodessubgen. n., established for those species with elongate ocular setae. Keys are also presented for the species ofMicrosphecodes s. str. andTrichosphecodes, along with the descriptions of the speciesMicrosphecodes(Microsphecodes)eickwortisp. n.,M. (M.)multirugosussp. n.,M. (M.)quechuasp. n., andM. (Trichosphecodes)trichophthalmussp. n. The Brazilian speciesNesosphecodes depressusGonçalves is transferred toNotoclopsgen. n., resulting in the new combinationNotoclops depressus(Gonçalves) comb. n. A key is presented to New World subgenera ofSphecodesLatreille, with the following new or resurrected groups:ProteranerRobertson,DrepaniumRobertson,SphecodiumRobertson,Asphecodiumsubgen. n., andBoreosphecodessubgen. n. The following new species are described among New WorldSphecodes:Sphecodes(Asphecodium)brevisulcatussp. n.,S. (Sphecodium)eustaurossp. n.,S. (S.)electrumsp. n.,S. (Sphecodes)zacatuchesp. n. The genusCaenosphecodesgen. n. is proposed forSphecodes pseudoredivivusAstafurova & Proshchalykin andS. redivivusBlüthgen, differing fromSphecodesby the elongate free part of the marginal cell, in this respect resembling New WorldMicrosphecodes. This results in the combinationsCaenosphecodes pseudoredivivus(Astafurova & Proshchalykin),C.sauteri(Meyer),C. simlaensis(Blüthgen), andC. redivivus(Blüthgen) comb. n. The currently employed characters for subgenera ofEupetersiaBlüthgens. l. fail to distinguish the groups. Accordingly, the key to subgenera is revised and the species newly organized as to subgenera.Cephalosphecodessubgen. n. is established forEupetersia macrocephalaPauly andE.mandibulataBlüthgen,Xanthocleptissubgen. n. is proposed forE.reticulata(Benoist), andPollinicleptissubgen. n. is erected forE.nathaniBaker,E.malayensis(Blüthgen),E.sabahensisPauly, andE.singaporensisPauly. A new species ofNesoeupetersia,E. dnopherasp. n., is described from Sabah, Malaysia and a tentative key provided to species of the subgenus.ThrausmusBuysson andCallosphecodesFriese are treated as independent genera, and the latter considered close toMelittocleptesgen. n., withMelittocleptes insularis(Smith) comb. n. as type species. A key is presented to Old World subgenera ofSphecodes, with the following new or resurrected groups:Proteraneropsissubgen. n.,Paradrepaniumsubgen. n.,Eusphecodessubgen. n.,SabulicolaVerhoeff,Caenocleptessubgen. n.,Xystoclopssubgen. n.,Callocleptessubgen. n., andNomiocleptessubgen. n.  more » « less

    Two new subgenera are established for enigmatic species of African small carpenter bees, genusCeratinaLatreille (Xylocopinae: Ceratinini).Ceratina foveiferaStrand is most similar toCopoceratinaTerzo & Pauly but differs in integumental coloration and sculpturing and absence of supraclypeal ridges, and is here classified inXestoceratinasubgen. n.Ceratina labrosaFriese is similar toCeratinas. str. andEuceratinaHirashima, Moure, & Daly but differs by the structure of the metasomal terga and male genitalia, and is placed inAlloceratinasubgen. n.

    A new genus and species of halictine bees (Halictinae: Halictini: Mexalictina) is described and figured from a mid-elevation forest in northwestern Costa Rica.Meliamelitta vulcanusgen. and sp. n. is allied toMexalictusEickwort but differs in the structure of the labral basal elevation, the obtuse epistomal sulcus, the elongate mandibles, the pectinate inner metatibial spur, the unique pterostigma, and the sculpturing of the basal area of the propodeum, among other features. A key is appended to the genera and subgenera of Mesoamerican, Central American, and Caribbean Halictinae to facilitate the recognition of the genus.

    Abstract We reconstruct the phylogeny of the most speciose genus of cuckoo bees, genus Nomada Scopoli, 1770, using 221 species from throughout its distribution, yet with a strong emphasis on the West Palearctic. For phylogenetic reconstruction, we sequenced ultraconserved elements, allowing robust phylogenetic estimates with both concatenation and coalescent-based methods. By integrating extensive information on Nomada host records, we study macroevolutionary patterns of host associations, transitions, and phylogenetic conservatism. Using Bayesian divergence time estimates, we assess the historical biogeography of the genus, focusing on the West Palearctic. Our results show that Nomada likely originated in the Eastern Mediterranean and Near Eastern region, and likely expanded its range to a near-global distribution from there. We recovered long-standing phylogenetic conservatism in the host usage of Nomada and provided strong statistical evidence for an ancestral host association with Andrena and its most recent common ancestor. However, host transitions occurred multiple times independently in the natural history of Nomada, and species of the genus are brood parasites in at least 5 genera and 4 different families of bees in the Old World. At last, we systematically revise the taxonomy of the Old World Nomada by integrating morphological study with our well-supported phylogenetic estimates. We re-establish the genus Acanthonomada Schwarz, 1966, stat. res., as a distinct, second genus in the tribe Nomadini. We recognize 13 subgenera for Nomada, 9 of which are described as new: Afronomada Straka and Bossert, subgen. nov., Colliculla Straka, subgen. nov., Gestamen Straka, subgen. nov., Hungias Straka, subgen. nov., Mininomada Straka, subgen. nov., Nomacolla Straka, subgen. nov., Nomonosa Straka, subgen. nov., Plumada Straka, subgen. nov., and Profuga Straka, subgen. nov. Aside from the subgenus Nomada s.s., we reinstitute 3 previously synonymized subgenera: Heminomada Cockerell, 1902, stat. res., Holonomada Robertson, 1903, stat. res., and Hypochrotaenia Holmberg, 1886 stat. res. A total of 15 subgeneric names are formally synonymized with the newly established subgeneric concepts.

    The following new genera and species of Striariidae are described from the states of California, Oregon and Washington: Nototrisaria ornata n. gen., n. sp., Maraplia napa n. gen., n. sp., Maraplia chico n. gen., n. sp., Maraplia schusteri n. gen., n. sp., Lamparia curryensis n. gen., n. sp., Lamparia bentonensis n. gen., n. sp., Lamparia pratensis n. gen., n. sp., Lamparia millicoma n. gen., n. sp., Rampalia cheathamensis n. gen., n. sp., Plaramia arcata n. gen., n. sp., Plaramia johnsonae n. gen., n. sp., Ralampia complexa n. gen., n. sp., and Ralampia filamentosa n. gen., n. sp.. The new species are all very small millipedes, 5.5 mm or less in length and with two or three ommatidia on each side of the head or blind. The majority have the sixth metazonital crest larger than the other crests and extended horizontally, so that the animals have the general appearance of having paranota. A new key to striariid genera is presented.
