Nomenclatural revision of Delphiniumsubg.Consolida (DC.) Huth (Ranunculaceae).

ABSTRACT: Recent molecular phylogenetic studies have indicated that Aconitella is embedded in Consolida, which in turn is embedded in Delphinium. We choose not to split the genus Delphinium (c. 300 species), as it is horticulturally and pharmaceutically important, by conserving a broad Delphinium by transferring the names from Consolida and Aconitella to Delphinium s.lat., and more precisely in the resurrected D.subg.Consolida. Including 58 species of Aconitella and Consolida within Delphinium causes fewer nomenclatural overall changes than do alternative schemes because most of the species of Aconitella and Consolida were once named under the name Delphinium. We present here the list of synonyms for the species once named under Consolida or Aconitella and gather the information relative to the types of these names. Two new combinations are provided, and 21 lectotypes are designated here.

Project description:PassiflorasubgenusDecalobasupersectionCieca is a monophyletic group of herbaceous to woody climbers found in subtropical and tropical regions of the world. The 19 species recognized here are primarily distributed in the southern United States, Mexico, Central America, South America, and the Caribbean. Two species, Passiflorasuberosa and Passiflorapallida, are also naturalized in various regions of the Old World. The species of the supersection are recognized by their small, apetalous, usually greenish flowers with the filaments of the corona mostly in two series. The plants commonly lack c-glycosylflavones but possess flavonol 3-O-glycosides. The supersection contains two problematic species complexes, Passiflorasuberosa and Passifloracoriacea. Phylogenetic relationships within supersection Cieca are investigated by means of phenetic and cladistic analyses of morphological and molecular (ITS 1 & 2) characters. The morphological and molecular data sets were analyzed separately because of incongruity due to taxon sampling and the complicated evolutionary history of entities within the Passiflorasuberosa complex. All analyses confirm the monophyly of the supersection. They also show that the Passiflorasuberosa complex is a non-monophyletic group of cryptic species, and inter-taxic hybridization and polyploidy have contributed to the confusing and complex pattern of variation evident within the group. Four taxa that were formerly included in this complex are recognized: Passiflorapallida, Passiflorasuberosasubsp.suberosa, Passiflorasuberosasubsp.litoralis, and Passifloratridactylites. On the basis of molecular and morphological data, three species from the Passifloracoriacea complex are recognized: Passifloracoriacea, Passiflorasexocellata, and Passifloramegacoriacea. A key, detailed descriptions, distribution maps, and illustrations are included in the revision. Pollination, dispersal, and herbivory of the group are reviewed. The distribution and ecology of the species within the supersection are also discussed.

Project description:The genus Centroptella Braasch & Soldán, 1980 is accepted here in a wide sense, i.e., including Chopralla Waltz & McCafferty, 1987. This genus concept is similar to the concept of the genus Bungona Harker, 1957 proposed by Salles et al. (2016), but with the generic name Centroptella instead of Bungona. The type species of Bungona, B. narilla Harker, 1957, has an unknown systematic position; the neotype designation proposed by Suter and Pearson (2001) is invalid, being inconsistent with the International Code of Zoological Nomenclature; the species name B. narilla and the generic name Bungona are nomina dubia, so the name Centroptella is the senior name for the genus under consideration. The generic names Chopralla and Crassolus Salles, Gattolliat & Sartori, 2016 both are junior synonyms of Centroptella (syn. nov.). The subgenera Bungona, Centroptella and Chopralla proposed by Salles et al. (2016) are unnatural. The following new combinations are proposed: Centroptella bintang (Marle, Salles & Gattolliat, 2016) comb. nov., Centroptella bifida (Shi & Tong, 2019) comb. nov., Centroptella fusina (Tong & Dudgeon, 2003) comb. nov., Centroptella fustipalpus (Lugo-Ortiz & McCafferty, 1998) comb. nov., Centroptella illiesi (Lugo-Ortiz & McCafferty, 1998) comb. nov., Centroptella inzingae (Crass, 1947) comb. nov., Centroptella papilionodes (Marle, Salles & Gattolliat, 2016) comb. nov., Centroptella pontica (Sroka, Godunko & Gattolliat, in Sroka et al. 2019) comb. nov., Centroptella ovata (Shi & Tong, 2019) comb. nov., Centroptella quadrata (Shi & Tong, 2019) comb. nov. and Centroptella saxophila (Agnew, 1961) comb. nov. The two Australian species, C. fustipalpus and C. illiesi, differ from each other in the shape of tergalii; corrections to the original description of C. fustipalpus are given based on re-examination of the holotype and paratypes; details of larval structures of C. illiesi are figured. Corrections to the former descriptions of the South African species C. inzingae and C. saxophila are given. Examination of type material led to the discovery that the original description of the Oriental species Centroptella liebenauae Soldán, Braasch & Muu, 1987 was based on two different species: the descriptions of imago and subimago belong to Centroptella longisetosa Braasch & Soldán, 1980 (the type species of Centroptella), and the description of larva belongs to a different species, which we describe here as Centroptella ingridae sp. nov. The holotype of C. liebenauae, a larva, should be considered lost; based on the date of collection, it belonged to C. longisetosa; a set of larval exuviae with the same collecting data as the holotype, is designated as the neotype of C. liebenauae, and a new synonymy is established: C. longisetosa = C. liebenauae syn. nov. The larvae originally assigned to C. liebenauae are placed to a new species Centroptella ingridae sp. nov. belonging to the inzingae-ingridae species group; all stages of development of this species are described based on male and female imagines reared from larvae in Thailand and on the misidentified paratypes of C. liebenauae from Vietnam. Centroptella longisetosa is redescribed based on the single paratype from China, the neotype and paratypes of C. liebenauae from Vietnam, and additional material from India. Additional data on the holotype of Centroptella colorata Soldán, Braasch & Muu, 1987 are given.
