Taxonomic Categories

Tribe Podochileae are a systematically highly challenging orchid group. Although the delimitation of Podochileae is relatively stable and monophyly of this tribe was confirmed by DNA-based phylogenetic analysis (Ng 2002), taxonomic categories within this group have changed frequently. Some groups are well separated morphologically and have been widely accepted as separate genera for a long time, whereas the majority of species was usually placed into a single genus Eria Lindley (1825: 904). Morphological traits have indicated polyphyly of this genus, which led some authors at various times to propose segregate genera. Nevertheless, these concepts were poorly supported by relevant data, and other authors retained these species in Eria s.l. Finally, combined DNA analysis confirmed the polyphyly of Eria (Ng 2002) and resulted in recognition of several previously neglected groups at generic level (Cribb & Ng 2005), including Campanulorchis Brieger (1981: 750).Campanulorchis was originally proposed by Brieger (1981) with the single species C. globifera Brieger (1981: 750). Seidenfaden (1982, 1992) demonstrated that this species was likely to be closely related to other species of Eria and classified it in Eria sect. Strongylaria Pfitzer (1888: 175). Later, Seidenfaden (1992) suggested separation of E. pannea Lindley (1842: 64) from remaining Indochinese species of E. section Strongylaria. Phylogenetic analyses of Ng (2002) confirmed polyphyly of the section Strongylaria. The type species of E. section Strongylaria, E. pannea, was transferred to Mycaranthes Blume (1825: 352; Chen & Wood 2009), and three of the remaining taxa were transferred to a revised concept of Campanulorchis (Ng & Cribb 2005, Cribb & Ng 2005): C. globifera, C. leiophylla (Lindley 1858: 57) Ng & Cribb (2005: 272) and C. pellipes (Riechenbach in Hooker 1890: 802) Ng & Cribb (2005: 272). Four years later Chen & Wood (2009) added C. thao (Gagnepain 1950: 503) Chen & Wood (2009: 346) because it shares many morphological characters with the other Campanulorchis species, especially with C. globifera. Finally, C. pseudoleiophylla (Wood 1981: 209) Wood (2011: 176) was added (Wood et al. 2011) because this species is morphologically similar to C. leiophylla (Wood 1981). Thus, five species were accepted in the most recent orchid classification (Chase et al. 2015, Govaerts 2017). Here I add two more species to Campanulorchis.

The authors provide a new circumscription for genera of the “Cryptanthoid complex” of Bromeliaceae subfam. Bromelioideae, originally composed of Cryptanthus, Lapanthus, Orthophytum, and Sincoraea, on the basis of new or re-evaluated ecological, geographical and morphological evidence, as well as molecular phylogenies. A new generic status is proposed for Cryptanthus subg. Hoplocryptanthus and two new genera, Forzzaea, and Rokautskyia, as well as four new subgenera in Orthophytum (Capixabanthus, Clavanthus, Krenakanthus, and Orthocryptanthus) are described to render taxonomic units monophyletic. The recognized taxa are well circumscribed by the combination of geographical range, ecology and morphological characters (sex distribution, leaf succulence, sepal and petal size and connation, petal appendages, pollen and stigma morphology, fruit size, calyx persistency, seed size and number per fruit). Field collected living specimens of 78 of the 81 species of Cryptanthus s.l., all species of Lapanthus, 58 of the 59 species of Orthophytum, and all species of Sincoraea were analysed in habitat and/or in cultivation, allowing the documentation and illustration of new and underutilized characters. The molecular analysis incorporated 91 accessions representing 33 species of Cryptanthus, all species (3) of Lapanthus, 42 species of Orthophytum, and 9 species of Sincoraea, including the type species for the first three genera and four outgroup taxa. The results suggest, that some morphological characters generally considered homoplasious for Bromelioideae, for the “Cryptanthoid complex”, are not homoplasious at least within the obtained, biogeographycally well delimited clades and their taxonomical utility is redeemed.

A comparative taxonomic study of Spiribacter and Halopeptonella species was carried out using a phylogenomic approach based on comparison of the core genome, orthologous average nucleotide identity (OrthoANIu), Genome-to-Genome Distance Calculator (GGDC) and average amino acid identity (AAI). Phylogenomic analysis based on 976 core translated gene sequences obtained from their genomes showed that Spiribacter aquaticus SP30T, S. curvatus UAH-SP71T, S. roseus SSL50T, S. salinus M19-40T and Halopeptonella vilamensis DSM 21056T formed a robust cluster, clearly separated from the remaining species of closely related taxa. AAI between H. vilamensis DSM 21056T and the species of the genus Spiribacter was ≥73.1 %, confirming that all these species belong to the same single genus. On the other hand, S. roseus SSL50T and S. aquaticus SP30T showed percentages of OrthoANIu and digital DNA–DNA hybridization of 98.4 % and 85.3 %, respectively, while these values among those strains and the type strains of the other species of Spiribacter and H. vilamensis DSM 21056T were ≤80.8 and 67.8 %, respectively. Overall, these data show that S. roseus SSL50T and S. aquaticus SP30T constitute a single species and thus that S. aquaticus SP30T should be considered as a later, heterotypic synonym of S. roseus SSL50T based on the rules for priority of names. We propose an emended description of S. roseus , including the features of S. aquaticus . We also propose the reclassification of H. vilamensis as Spiribacter vilamensis comb. nov.

The Chaetosphaeriaceae are a diverse group of pigmented, predominantly phialidic hyphomycetes comprised of several holomorphic genera including Chaetosphaeria, the most prominent genus of the family. Although the morphology of the teleomorphs of the majority of Chaetosphaeria is rather uniform, their associated anamorphs primarily exhibit the variability and evolutionary change observed in the genus. An exception from the morphological monotony among Chaetosphaeria species is a group characterised by scolecosporous, hyaline to light pink, multiseptate, asymmetrical ascospores and a unique three-layered ascomatal wall. Paragaeumannomyces sphaerocellularis, the type species of the genus, exhibits these morphological traits and is compared with similar Chaetosphaeria with craspedodidymum- and chloridium-like synanamorphs. Morphological comparison and phylogenetic analyses of the combined ITS-28S sequences of 35 isolates and vouchers with these characteristics revealed a strongly-supported, morphologically well-delimited clade in the Chaetosphaeriaceae containing 16 species. The generic name Paragaeumannomyces is applied to this monophyletic clade; eight new combinations and five new species, i.e. P. abietinussp. nov., P. eleganssp. nov., P. granulatussp. nov., P. sabinianussp. nov. and P. smokiensissp. nov., are proposed. A key to Paragaeumannomyces is provided. Using morphology, cultivation studies and phylogenetic analyses of ITS and 28S rDNA, two additional new species from freshwater and terrestrial habitats, Codinaea paniculatasp. nov. and Striatosphaeria castaneasp. nov., are described in the family. A codinaea-like anamorph of S. castanea forms conidia with setulae at each end in axenic culture; this feature expands the known morphology of Striatosphaeria. A chaetosphaeria-like teleomorph is experimentally linked to Dendrophoma cytisporoides, a sporodochial hyphomycete and type species of Dendrophoma, for the first time.

Chakrabartia godavariana PRB40T was compared with Aestuariisphingobium litorale SYSU M10002T to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of C. godavariana PRB40T had high similarity (99.8 %) to that of A. litorale SYSU M10002T. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus Chakrabartia . A draft genomic comparison between the two strains revealed an average nucleotide identity of 97.3 % and a digital DNA–DNA hybridization estimate of 79.5±2.9 %, strongly indicating that the two strains represented a single species. In addition, neither strain displayed any striking differences in metabolic, physiological or chemotaxonomic features. Therefore, we propose that Aestuariisphingobium litorale is a later heterotypic synonym of Chakrabartia godavariana .

Cortinarius section Xenosmatae, originally based on solely morphological characters, was subsequently shown to contain phylogenetically distantly related species. The type species C. xenosma is a singleton, and this study aims to revise the other members of the section using combined molecular (nrDNA ITS and LSU) and morphological data. Based on phylogenetic analyses using RAxML, PhyML and Bayesian Inference and additional morphological features one new species (C. paraxenosma) and one new section (sect. Olorinati) are proposed. Furthermore sect. Carbonelli is extended and emended to include two former members of sect. Xenosmatae. A key to the species in New Zealand with xenosmatoid morphology is provided.

Principal Species

Usnea species of the Neuropogon group are amongst the most widespread and abundant macrolichens in Antarctic regions. Four principal species, U. antarctica, U. aurantiaco-atra, U. sphacelata and U. subantarctica, have been described on morphological grounds. However, identification to species level is often difficult and atypical morphologies frequently arise. Over 400 specimens were collected on the Antarctic Peninsula and Falkland Islands. Both morphological and molecular characters (ITS and RPB1) were used to compare samples to clarify taxonomic relationships. Morphological characteristics used included presence of apothecia, apothecial rays, soredia, papillae, fibrils, pigmentation and the diameter of the central axis as a proportion of branch diameter. Results revealed a very close relationship between U. antarctica and U. aurantiaco-atra, suggesting that they might constitute a species pair or be conspecific. Usnea sphacelata was comprised of at least two genetically distinct groups with no clear differences in morphology. One group included the first reported fertile specimen of this species. Usnea subantarctica was phylogenetically distinct from the other main Antarctic Usnea species, but clustered with U. trachycarpa. Genetic variation was evident within all species although there was no clear correlation between geographic origin and genetic relatedness. Phylogenetic analyses indicated that species circumscription in the Neuropogon group needs revision, with the principal species being non-monophyletic. None of the morphological characters, or groups of characters, used in this study proved to be completely unambiguous markers for a single species. However, axis thickness was supported as being informative for the identification of monophyletic lineages within the group.

Liver Flukes

As a result of their feeding habits, birds of 36 or more families have proved to be susceptible to a large number of dicrocoeliine trematodes living principally in the bile ducts and gall-bladder of their hosts (Faust, 1966). As more species of avian hosts are examined and their liver flukes studied, additional species are described and previously recognized species are reported from new hosts and new geographical areas (Lumsden and Zischke, 1963).In 1958, Yamaguti differentiated Dicrocoeliinae Looss, 1899 into 8 tribes, one of which he named Lutztrematini, having as cardinal characters an acetabulum much larger than oral sucker and testes tandem or diagonal; single genus Lutztrema Travassos, 1941 and L. obliquum (Travassos, 1917) as type species. The avian dicrocoeliine species described in this communication has important morphological characters agreeing with the Lutztrematini and others lacking agreement. In consequence, it has seemed necessary to create a new genus, Paralutztrema, related to, but generically separate from Lutztrema.

AbstractFrom the endemic New World halyine genus Brochymena, two genera are recognized. New morphological characters at the generic level are described. Parabrochymena, new genus, with Pentatoma arborea Say as type species, is erected to contain 10 taxa formerly included in Brochymena. New combinations are Parabrochymena aculeata (Distant), P. apiculata (Van Duzee), P. arborea (Say), P. barberi barberi (Ruckes), P. barberi diluta (Blatchley), P. cuspidata (Distant), P. enigmatica (Ruckes), P. florida (Ruckes), P. haedula (Stål), and P. poeyi (Guérin-Méneville). Brochymena is redefined with 20 taxa: B. affinis Van Duzee, B. cariosa Stål, B. carolinensis (Westwood), B. chelonoides Ruckes, B. dilata Ruckes, B. exardentia Ruckes, B. hoppingi Van Duzee, B. humeralis Ruckes, B. laevigata Ruckes, B. lineata Ruckes, B. marginella Stål, B. myops Stål, B. parva Ruckes, B. punctata punctata Van Duzee, B. punctata pallida Blatchley, B. pilatei Van Duzee, B. quadripustulata (Fabricius), B. splendida Ruckes, B. sulcata Van Duzee, and B. tenebrosa Walker. Four synonymies are established: B. marginella Stål = B. carolinensis (Westwood); B. pilatei Van Duzee = B. sulcata Van Duzee; B. laevigata Ruckes = B. myops Stål; B. exardentia Ruckes = B. lineata Ruckes. Lectotypes are designated for B. affinis Van Duzee, B. cariosa Stål, B. myops Stål, B. punctata pallida Blatchley, and B. p. punctata Van Duzee. Species groups of Brochymena are characterized, and a key to all taxa is presented for the first time. As appropriate, for each species of Brochymena, the following are provided: citation of original description, synonymies, type material, diagnosis, description, geographical distribution, taxonomic comments, natural history, and illustrations of important structural characters. Chorological affinities are presented and systematic relationships are hypothesized.

Geographic Overlap

The fern genus Microsorum is not monophyletic, with previous phylogenetic analyses finding three lineages to group not with the type species, but to form a grade related to the 13 species of Lecanopteris. These three lineages have recently been recognised as separate genera: Bosmania, Dendroconche, and Zealandia. Here, we explore the morphological characterisation of Lecanopteris and these other three lecanopteroid genera. While the traditional circumscription of Lecanopteris has seemed sacrosanct, its defining morphological character states of rhizome cavities and ant brooding associations occur in other lecanopteroid ferns and elsewhere in the Polypodiaceae. Instead, we suggest that the morphological characterisation of an expanded Lecanopteris including the Dendroconche and Zealandia lineages is just as good, if not better, with the pertinent character states being the absence of sclerenchyma strands in the rhizome and at least some fronds having Nooteboom’s type 5 venation pattern. This wider circumscription is also better able to accommodate phylogenetic uncertainty, and it means that groups of species traditionally placed together in a single genus are not distributed across different genera. General users familiar with the narrower circumscription of Lecanopteris will not be significantly disrupted, because there is little geographic overlap with the lineages added to the genus. Consequently, we make new combinations in Lecanopteris for 11 species and one subspecies.
