The Trigonostemon species outside Malesia are taxonomically revised based on herbarium collections and fresh material. The research history in the concerning regions, i.e., the Indian subcontinent (including S India, SriLanka, Bangladesh and Myanmar), China, Thailand, Indochina, NE Australia and New Caledonia, is briefly summarised. A total of 32 species are accepted (including one doubtful species) and 17 names are newly treated as synonyms. Trigonostemon montanus is newly described for India. Regional identification keys, nomenclature, descriptions, geographic distributions and taxonomic notes are provided. Together with our previous work, the genus is now fully revised. A total of 59 species are accepted. A full identification list of all Trigonostemon collections seen is presented.

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.

The scleractinian family Lobophylliidae is undergoing a major taxonomic revision thanks to the combination of molecular and morphological data. In this study, we investigate the evolutionary relationships and the macro- and micromorphology of six nominal coral species belonging to two of the nine molecular clades of the Lobophylliidae, clades A and B, and of Symphyllia wilsoni, a lobophylliid species analyzed from a molecular point of view for the first time. Sequence data from mitochondrial DNA (COI and the intergenic spacer between COI and l-rRNA), and nuclear DNA (histone H3 and ITS region) are used to generate robust molecular phylogenies and a median-joining haplotype network. Molecular results are strongly in agreement with detailed observations of gross- and fine-scale morphology of skeletons, leading to the formal revision of the genera Micromussa and Homophyllia and the description of two newly discovered zooxanthellate shallow-water species, Micromussa pacifica sp. nov. Benzoni & Arrigoni and Micromussa indiana sp. nov. Benzoni & Arrigoni, and a new genus, Australophyllia gen. nov. Benzoni & Arrigoni. In particular, Acanthastrea lordhowensis and Montastraea multipunctata are moved into Micromussa, A. hillae is synonymized with A. bowerbanki and is transferred to Homophyllia, and a revised diagnosis for both genera is provided. Micromussa pacifica sp. nov. is described from the Gambier Islands with its distribution spanning New Caledonia and eastern Australia. Despite a superficial resemblance with Homophyllia australis, it has distinctive macroand micromorphological septal features. Micromussa indiana sp. nov., previously identified as M. amakusensis, is here described from the Gulf of Aden and the southern Red Sea as a distinct species that is genetically separated from M. amakusensis and is morphologically distinct from the latter due to its smaller corallite size and lower number of septa. Finally, molecular trees show that S. wilsoni is closely related, but molecularly separated from clades A and B, and, also based on a unique combination of corallite and sub-corallite characters, the species is moved into Australophyllia gen. nov. These findings confirm the need for using both genetic and morphological datasets for the ongoing taxonomic revision of scleractinian corals.

Stachys is traditionally accepted to present great taxonomic and nomenclatural complexity. It shows a wide range of variability that is difficult to define. In the present study, a taxonomic revision of Stachys sect. Olisia (Lamiaceae) in Turkey was presented. Stachys comprises 87 species (113 taxa) in Flora of Turkey, 58 of which (51%) are endemic to Turkey. Stachys sect. Olisia is represented by 14 species (20 taxa) in Turkey, of which S. distans var. distans is reported for the first time from Turkey, and S. annua subsp. annua var. lycaonica is synonymised to S. annua subsp. annua. Herein, morphological descriptions, diagnostic characters, detailed illustrations, distribution maps, IUCN threat categories and taxonomic comments are presented for all accepted taxa. Furthermore, identification keys are also included for the accepted Turkish species, subspecies and varieties in the section.

This study examines the phylogeny, taxonomy, distribution and biology of the gasteruptiid subfamily Hyptiogastrinae and, at the same time, presents an overview of the family. Following a cladistic analysis of 35 discrete morphological characters, two monophyletic genera are recognised, Hyptiogaster Kieffer and Pseudofoenus s. l. Kieffer. As a consequence, the genera Aulacofoenus Kieffer, Crassifoenus Crosskey, and Eufoenus Szépligeti are synonymised with Pseudofoenus. A total of 88 species are recognised for the subfamily, 10 species of Hyptiogaster, which are restricted to mainland Australia, and 78 species of Pseudofoenus, 40 of which are described as new. Pseudofoenus has a restricted Gondwanan distribution and is found in Australia including Tasmania (65 spp.), New Guinea and New Britain (5 spp.), the south-west Pacific (New Caledonia, New Hebrides and Fiji – 2 spp.), New Zealand (4 spp.) and South America (2 spp.). No new species have been recorded from either New Zealand or South America. For Pseudofoenus, information on the distribution of each species, their biology (if known) and an identification key are presented.Following a taxonomic revision, the following new species are described: P. baileyi, sp. nov., P. baitetaensis, sp. nov., P. beverlyae, sp. nov., P. caperatus, sp. nov., P. cardaleae, sp. nov., P. carrabinensis, sp. nov., P. claireae, sp. nov., P. collessi, sp. nov., P. coorowensis, sp. nov., P. crosskeyi, sp. nov., P. douglasorum, sp. nov., P. eliseae, sp. nov., P. ericae, sp. nov., P. eustonensis, sp. nov., P. feckneri, sp. nov., P. gressitti, sp. nov., P. gullanae, sp. nov., P. hackeri, sp. nov., P. imbricatus, sp. nov., P. iqbali, sp. nov., P. kadowi, sp. nov., P. karimuiensis, sp. nov., P. kelleri, sp. nov., P. leinsterensis, sp. nov., P. macdonaldi, sp. nov., P. malkini, sp. nov., P. marshalli, sp. nov., P. masneri, sp. nov., P. mitchellae, sp. nov., P. morganensis, sp. nov., P. nalbarraensis, sp. nov., P. pumilis, sp. nov., P. schmidti, sp. nov., P. stevensi, sp. nov., P. tasmaniensis, sp. nov., P. taylori, sp. nov., P. umboiensis, sp. nov., P. walkeri, sp. nov. and P. zborowskii, sp. nov. The synonymy of Aulacofoenus, Crassifoenus and Eufoenus with Pseudofoenus result in the following new combinations: from Aulacofoenus: P. bungeyi (Jennings & Austin), comb. nov., P. deletangi (Schletterer), comb. nov., P. fallax (Schletterer), comb. nov., P. fletcheri (Jennings & Austin), comb. nov., P. goonooensis (Jennings & Austin), comb. nov., P. infumatus (Schletterer), comb. nov., P. kurmondi (Jennings & Austin), comb. nov., P. loxleyi (Jennings & Austin), comb. nov., P. marionae (Jennings & Austin), comb. nov., P. perenjorii (Jennings & Austin), comb. nov., P. swani (Jennings & Austin), comb. nov., P. thoracicus (Guérin Menéville), comb. nov., P. whiani (Jennings & Austin), comb. nov. and P. wubinensis (Jennings & Austin), comb. nov.; from Crassifoenus: P. houstoni (Jennings & Austin), comb. nov., P. grossitarsis (Kieffer), comb. nov and P. macronyx (Schletterer), comb. nov.; and from Eufoenus: P. antennalis (Schletterer), comb. nov., P. australis (Westwood), comb. nov., P. crassitarsis (Kieffer), comb. nov., P. darwini (Westwood), comb. nov., P. extraneus (Turner), comb. nov., P. ferrugineus (Crosskey), comb. nov., P. floricolus (Turner), comb. nov., P. inaequalis (Turner), comb. nov., P. melanopleurus (Crosskey), comb. nov., P. minimus (Turner), comb. nov., P. nitidiusculus (Turner), comb. nov., P. patellatus (Westwood), comb. nov., P. pilosus (Kieffer), comb. nov., P. reticulatus (Crosskey), comb. nov., P. rieki (Crosskey), comb. nov., P. ritae (Cheesman), comb. nov. and P. spinitarsis (Westwood), comb. nov.

AbstractThe paper introduces the Herbarium Database of Hungarian Orchids which contains all records of orchid (Orchidaceae) specimens stored in the Hungarian herbaria. All data from the herbarium sheets were entered into the database, and secondary data were also added it; including a taxonomic revision in line with current theory. Only unique data was considered, yielding 7,658 records of 55 species from 452 collectors. It covers the whole territory of Hungary, and spans two centuries ranging from 1804 to the present. The temporal frequency of collections shows a peak in the middle of the 20th century. The most effective collectors came from this era, and the name of Rezső Soó and his followers can be mentioned as most prominent. As in other countries, a decline in collection is seen in the last decades of the 20th century. A geographically uneven coverage of collections was observed, and the such heavily underrepresented regions could be identified with the help of the database. However, the value of collection for scientific purposes is emphasised, as can be readily seen in this database. Taxonomically, seven recently described species could be identified, which were collected before their description under other names more than one century ago. On the other hand, the earlier presence of species now considered to be extinct could be unequivocally proven, as in the case of Malaxis monophyllos. The multiple application of herbaria is illustrated by some examples, reinforcing unambiguously the usefulness of collecting for scientific purposes. Furthermore, new, as yet unforeseen, application of herbarium collections can be expected.
