The Malagasy genus Carphalea (Rubiaceae) consists of six species (C. angulata, C. cloiselii, C. kirondron, C. linearifolia, C. madagascariensis, C. pervilleana) of shrubs or small trees and is recognizable by a distinctly lobed calyx, 2(–4)-locular ovaries, each locule with several ovules on a rod-like stalk arising from the base of the locule, and indehiscent fruits. Carphalea linearifolia, rediscovered in 2010, has not previously been included in any Rubiaceae molecular phylogenetic studies. We re-investigated the monophyly of Carphalea using sequence data from chloroplast (rps16 and trnT-F) and nuclear (ITS and ETS) markers analysed with parsimony and Bayesian methods. Carphalea linearifolia forms a clade with C. cloiselii and the type species C. madagascariensis. This clade is sister to a clade consisting of the rest of the Carphalea species plus the genus Triainolepis. According to these results, the new genus Paracarphalea is here described to accommodate Carphalea angulata, C. kirondron, and C. pervilleana. The conservation status of Carphalea linearifolia is assessed as critically endangered according to IUCN criteria.

Chimonanthus of Calycanthaceae is a small endemic genus in China, with unusual winter-blooming sweet flowers widely cultivated for ornamentals and medicinal uses. The evolution of Chimonanthus plastomes and its phylogenetic relationships remain unresolved due to limited availability of genetic resources. Here, we report fully assembled and annotated chloroplast genomes of five Chimonanthus species. The chloroplast genomes of the genus (size range 153,010 – 153,299 bp) reveal high similarities in gene content, gene order, GC content, codon usage, amino acid frequency, simple sequence repeats, oligonucleotide repeats, synonymous and non-synonymous substitutions, and transition and transversion substitutions. Signatures of positive selection are detected in atpF and rpoB genes in C. campanulatus. The correlations among substitutions, InDels, and oligonucleotide repeats reveal weak to strong correlations in distantly related species at the intergeneric levels, and very weak to weak correlations among closely related Chimonanthus species. Chloroplast genomes are used to reconstruct a well-resolved phylogenetic tree, which supports the monophyly of Chimonanthus. Within Chimonanthus, C. praecox and C. campanulatus form one clade, while C. grammatus, C. salicifolius, C. zhejiangensis, and C. nitens constitute another clade. Chimonanthus nitens appears paraphyletic and is closely related to C. salicifolius and C. zhejiangensis, suggesting the need to reevaluate the species delimitation of C. nitens. Chimonanthus and Calycanthus diverged in mid-Oligocene; the radiation of extant Chimonanthus species was dated to the mid-Miocene, while C. grammatus diverged from other Chimonanthus species in the late Miocene. C. salicifolius, C. nitens(a), and C. zhejiangensis are inferred to have diverged in the Pleistocene of the Quaternary period, suggesting recent speciation of a relict lineage in the subtropical forest regions in eastern China. This study provides important insights into the chloroplast genome features and evolutionary history of Chimonanthus and family Calycanthaceae.

We describe a new genus, Dishkeya Stonis, gen. nov., and a new species, Dishkeya gothica Diškus & Stonis, sp. nov., discovered feeding on Gouania lupuloides (L.) Urb., Rhamnaceae. We discuss the diagnostics of Tischeria Zeller and Dishkeya gen. nov.; the latter is characterized by the absence of a juxta, the presence of a pseudognathos, and well-developed carinae of the phallus in the male genitalia. We newly combine Tischeria bifurcata Braun and Tischeria gouaniae Stonis & Diškus with Dishkeya and designate the latter species as the type species of the new genus. All species treated in the paper are illustrated with drawings or photographs of the male genitalia.

Abstract There are 96 endemic species of Eumolpinae (Coleoptera: Chrysomelidae) described from New Caledonia, but some estimates propose that the actual number could be at least twice this figure. Not surprisingly, when a particular species assemblage has been revised, the number of species in that group increases significantly. Here, we revise the New Caledonian endemic genus Taophila Heller, 1916, the best studied in this fauna and currently known to include eleven species, one in the subgenus Jolivetiana Gómez-Zurita & Cardoso, 2014, and ten in the nominal subgenus. The analysis of morphological differences in a large sample of Taophila and the validation of the resulting species hypotheses in an integrative fashion based on a phylogenetic analysis of partial mtDNA sequences (cox1 and rrnS) resulted in the addition of eleven more taxa. Taxonomic splits mainly reinterpreted the previous observation of mtDNA paraphyly affecting T. subsericea Heller, 1916, shown to represent a complex of species mostly distinguishable by diagnostic differences among females. The new species described are: T. bituberculata n. sp., T. carinata n. sp., T. dapportoi n. sp., T. davincii n. sp., T. draco n. sp., T. goa n. sp., T. hackae n. sp., T. samuelsoni n. sp., T. sideralis n. sp., T. taaluny n. sp. and T. wanati n. sp. These additions and the synonymy T. subsericea Heller = Stethotes mandjeliae Jolivet, Verma & Mille, 2010 n. syn., bring to 21 the total number of species in Taophila. Moreover, we also found the first evidence of mtDNA introgression between species of New Caledonian Eumolpinae, resulting from putative recent hybridization of T. subsericea and T. dapportoi where these species coexist. We describe a model incorporating the mtDNA genealogy of T. subsericea about the conditions that may have favored the secondary geographic encounter required for the hybridization of these species.

Biological Aspects

A taxonomic revision of Calytrix Labill., an Australian endemic genus of Myrtaceae, tribe Chamelaucieae, is presented. Lhotskya Schauer is reduced to a synonym of Calytrix. Seventy-two species are recognized of which the following 22 are described as new: C. amethystina, C. carinata, C. chrysantha, C. divergens, C. duplistipulata, C. eneabbensis, C. erosipetala, C. formosa, C. gurulmundensis, C. gypsophila, C. habrantha, C. islensis, C. microcoma, C. parvivallis, C. paucicostata, C. platycheiridia, C. praecipua, C. rupestris, C. similis, C. truncatifolia, C. verruculosa and C. warburtonensis. Two species comprise two subspecies each, of which one, C. simplex subsp. suboppositifolia, is also described as new. Other than autonyms the following new names result from the transfer of Calycothrix and Lhotskya species to Calytrix, and/ or changes in taxonomic rank: C, acuttfolia, C, breviseta subsp. stipulosa, C. brownii, C. drummondii, C. glaberrima, C. harvestiana, C. merrelliana, C. nematoclada, C. purpurea, C. smeatoniana and C. sylvana. Distinctive features of the morphology are discussed. A new term, cheiridium, is proposed for an apparently adaptive structure formed from the peduncle and persistent, connate bracteoles. Other biological aspects that are discussed briefly include floral biology, fruit and dispersal, and geography. An informal infrageneric classification, based largely upon floral features, is outlined. New taxa are illustrated. Distribution maps are provided for all taxa.
