AbstractCaloplaca herbidella (Hue) H. Magn. and C. furfuracea H. Magn. are two isidiate, epiphytic species in the large genus Caloplaca. Caloplaca herbidella in a strict sense is normally grey and fertile with thick, somewhat coralloid isidia, but orange, sterile forms with thin isidia also occur. Caloplaca furfuracea is superficially similar morphologically to C. herbidella s. str. but has thinner, more granular isidia and generally a darker grey colour. Doubts have been raised as to whether C. furfuracea should be acknowledged as a proper species or incorporated in C. herbidella. Using morphometric methods and molecular analysis of the nrITS DNA gene we show that C. herbidella and C. furfuracea are two clearly separated species. Furthermore, the mainly sterile, orange form of C. herbidella can be regarded as a separate species that is here described as C. coralliza Arup & Åkelius. All three species are described in detail, including photographs and notes on their ecology. Finally, new distribution maps for Europe show that C. herbidella and C. coralliza are widespread in Europe, but the latter is probably less common than the former. Caloplaca furfuracea is clearly very rare in Europe with only few collections from Switzerland and Sweden, but seems to be more common in North America.

General Aspects

Palpada Macquart, 1834 is a large genus of tropical Eristaliini flies with distribution restricted to the New World (Diptera : Syrphidae : Eristalinae). Most species were initially placed within Eristalis Latreille, 1804. In 1972, most Neotropical species were transferred to Palpada when F.C. Thompson divided Eristalis sensu lato into three genera: Eristalis, Eoseristalis Kanervo, 1938 and Palpada. The latter genus was divided by Thompson (1981) into three groups of species: scutellaris, agrorum and vinetorum. In the present study, the species of the scutellaris group are revised and the phylogenetic relationships among its species are reconstructed based on adult morphology. The cladistic analysis of the 24 terminal species and 48 characters of external morphology and male and female genitalia, produced one cladogram under equal weights. The monophyly of the scutellaris group was corroborated. Twelve species are recognised within the group, of which one is described as new: Palpada cordiformis Morales, sp. nov., P. claudia (Curran), P. conica (Fabricius), P. doris (Curran), P. erratica (Curran), P. fuliginosa (Hull), P. megafemur Thompson, P. melanaspis (Wiedemann), P. precipua (Williston), P. rufoscutellata (Sack), P. scutellaris (Fabricius) and P. vera (Hull). Two new synonymies are proposed: P. dorothea (Hull, 1942) = P. melanaspis (Wiedemann, 1830); and P. glabella (Hull, 1942) = P. fuliginosa (Hull, 1935). The lectotype is designated for Eristalis melanaspis. An identification key, a catalogue, distribution maps, illustrations of general aspects, illustrations of male and female genitalia and scanning electron micrographs are provided.

Infraspecific Taxa

Morphological studies of the Carex stricta complex confirm hypotheses based on chromosome numbers that there are three distinct species in eastern North America, Carex stricta, C. emoryi, and C. haydenii, but they do not indicate the existence of any distinct infraspecific taxa. These species are compared phenetically with all other North American species of section Phacocystis. Results indicate that the three species examined here do not form a closely related subgroup within the section as suggested by previous authors. Distribution maps, descriptions, and synonomy are provided for these species, and a complete key to the species of section Phacocystis in eastern North America is given.

High Degree

Petasites Mill. (Asteraceae: Senecioneae) is a taxonomically difficult genus of polygamodioecious, perennial herbs with a widespread distribution across North America. As many as 10 species and as few as two species (Petasites sagittatus (Banks ex Pursh) A. Gray and Petasites frigidus (L.) Fries with three varieties), with one hybrid taxon, have been recognized previously. Considerable taxonomic controversy has surrounded the genus as a result of a conservative floral morphology and a high degree of polymorphism in leaf morphology. Additionally, a number of intergrading leaf forms among those with rather consistent taxonomic characteristics across various treatments have contributed to the taxonomic ambivalence surrounding Petasites. Our taxonomic revision of North American Petasites is based on results obtained from recent multivariate morphometric and isozyme analyses. These data have indicated that taxa of Petasites are not sufficiently differentiated, morphologically or isozymically, from one another to warrant the recognition of separate species. Therefore, Petasites is circumscribed as a single species containing three varietal taxa and one hybrid taxon between two of the varieties. Although our circumscription of P. sagittatus is in accordance with most previous circumscriptions, we have removed it from the rank of species to varietal status under P. frigidus. The new combination Petasites frigidus var. sagittatus (Banks ex Pursh) Cherniawsky is proposed. Subsequent to the new status of one of its parental taxa (P. frigidus var. sagittatus), the new combination for Petasites ×vitifolius (Greene) Bogle is proposed: Petasites frigidus var. ×vitifolius (Greene) Cherniawsky. The three entities of the frigidus complex are united under one polymorphic taxon, P. frigidus var. frigidus and the circumscription and name of Petasites frigidus var.palmatus (Ait.) Cronq. is in accordance with previous authors. A complete list of synonymy and a key to the taxa of Petasites is presented together with distribution maps.Key words: Petasites, Asteraceae, Senecioneae, North America, taxonomic revision.

A taxonomic revision of the neotropical palm genus Welfia based on morphological data and morphometric methods was carried out. One hundred and five herbarium specimens were scored for one qualitative variable and 19 quantitative variables. Based on the qualitative variable, fruit shape, two species are recognized. One (W. regia) is widely distributed in Central America and northwestern South America from Nicaragua to Colombia and Ecuador; the second, described here (W. alfredii) is restricted to a small area of central Peru. Nomenclature, descriptions, and distribution maps are provided for each species, and images of the type specimen of the new species are also provided.

Respective Species

The South American genus Panca Evans, 1955 and its respective species are revised. Previous to this study, the genus included solely its type species, Lerodea subpunctuli Hayward, 1934, until Panca moseri Dolibaina, Carneiro & O. Mielke, 2017 was described recently. However, as a result of a broader morphological study including closely related genera, we here propose that Panca assembles 12 species, most of which inhabit open environments such as the Cerrado biome and the natural grasslands of the Atlantic Forest biome. Eight species formerly included among other genera of Moncina are here combined with Panca: Panca satyr (Evans, 1955) comb. nov., Panca tobiasi (Mielke, 1992) comb. nov., Panca trogon (Evans, 1955) comb. nov., Panca steinhauseri (Dolibaina & A. Warren, 2015) comb. nov., Panca acroleuca (Plötz, 1884) comb. nov., and Panca mirnae (O. Mielke, Dolibaina, Carneiro & A. Warren, 2015) comb. nov. (all formerly in Artines Godman, 1901), Panca paulo (Bell, 1932) comb. nov. (formerly in Eutocus Godman, 1901), and Panca mictra (Evans, 1955) comb. nov. (formerly in Vidius Evans, 1955). Additionally, two new species are described from Brazil: Panca puri Medeiros, O. Mielke & Casagrande sp. nov. (from Pará, Pernambuco, Minas Gerais, Rio de Janeiro and Paraná) and Panca xavante Medeiros, O. Mielke & Dolibaina sp. nov. (from Mato Grosso, Goiás, Distrito Federal and Minas Gerais). A neotype for Apaustus acroleuca Plötz, 1884 is designated. Illustrations of the male and female genitalia and distribution maps are presented for all the species of Panca and an identification key is provided for both sexes.

AbstractThe systematics of Acalymma sensu stricto of North America including Mexico are revised. Acalymma sensu stricto is defined and distinguished from the other species groups of Acalymma. Sixteen species are discussed including four new species: A. blomorum, A. palomarense, A. invenustum, and A. luridifrons all from Mexico. Three new subspecies of A. blandulum (LeConte) are described: blandulum (LeConte) new status, nigriventre, and yucatanense. Acalymma coruscum costaricense Bechyné is placed as a synonym of A. innubum (Fabricius). Keys are presented to all species and subspecies. Habitus and male genitalia drawings are given for all species and distribution maps are given where appropriate.
