This contribution presents a study of Iberian and Californian populations of Aporcelaimellus simplex, including morphological, morphometric and molecular data. The species is characterised and distinguished by its lip region offset by an expansion, pars refringens vaginae absent, and conical tail with a small but distinct hyaline terminal portion. No significant difference exists between American and European populations. Molecular data and the derived evolutionary tree show a topology in which this species forms a well-supported group with members of Discolaiminae, far from other representatives of Aporcelaimellus. Putting special emphasis in the absence of pars refringens vaginae, A. simplex is transferred to the genus Aporcella. The taxonomy of this genus is revised in depth, with the proposal of an emended diagnosis, the provision of a list of 13 valid species (mostly new combinations from Aporcelaimellus) as well as a key to their identification and a compendium of their main morphometrics. Aporcella debruinae sp. n. is proposed for Aporcelaimellus papillatus apud de Bruin & Heyns, 1992.

Seed Testa

Sinalliaria is described here as a new genus of the family Brassicaceae from eastern China, based on the morphological characters and molecular sequences. Sinalliaria differs from the related genus Orychophragmus in having basal leaves petiolate, simple or rarely with 1‒3 lateral lobes (not pinnatisect); cauline leaves petiolate, cordate at base (not sessile, auriculate or amplexicaul at base); petals obovate to narrowly obovate, claw inconspicuous (not broadly obovate, with a claw as along as sepal); siliques truncate (not long-beaked) at apex. The microscopic characters of seed testa also show significant differences between Sinalliaria and Orychophragmus. Phylogenetic evidence from DNA sequences of nuclear ribosomal ITS and plastid region trnL-trnF indicates that Sinalliaria is a distinct group related to Orychophragmus and Raphanus, but these three genera do not form a clade. The new genus Sinalliaria is endemic to eastern China and has only one species and one variety. The new combinations, S. limprichtiana (Pax) X. F. Jin, Y. Y. Zhou & H. W. Zhang and S. limprichtiana var. grandifolia (Z. X. An) X. F. Jin, Y. Y. Zhou & H. W. Zhang are proposed here.

A total evidence phylogeny for Pontederiaceae is herein presented based on new morphological and previously published molecular data. Our results led us to re-circumscribe Pontederia to include Monochoria, Pontederias.s. and the polyphyletic Eichhornia. We provide the needed ten new combinations and 16 typifications, arrange a total of 25 accepted species (six representing re-established names) in 5 new subgenera. Furthermore, we provide an identification key for the two genera accepted by us in Pontederiaceae, an identification key to the subgenera, identification keys to the species of each subgenus and commentaries on Pontederias.l., as well as for each subgenus and each species.

Morphological And Molecular Data

Abstract Dacrymycetes has four families and 13 genera, few of them with molecular data available and then usually polyphyletic in phylogenetic analyses. Dacrymyces Nees is one of the polyphyletic genera in Dacrymycetes and it was introduced to accommodate one species, D. stillatus Nees. The morphological features of the genus are a homogeneous composition of the intra-structure and an amphigenous or superior hymenium. In this study, we included Neotropical specimens in the phylogeny of the Dacrymycetes and Dacrymyces s.s. is emended to include species with resupinate basidiomata, unilateral hymenium and heterogeneous context. In this new delimitation, the new species Dacrymyces flavobrunneus is described using morphological and molecular data and three new combinations (D. ceraceus comb. nov., D. maxidorii comb. nov. and D. spathularia comb. nov.) are proposed based on DNA analyses.

The genera Boonea Robertson, 1978, Chrysallida Carpenter, 1856, Fargoa Bartsch, 1909, Ivara Dall & Bartsch, 1903, Mumiola A. Adams, 1863, Odostomella Bucquoy, Dautzenberg & Dollfus, 1883, Parthenina Bucquoy, Dautzenberg & Dollfus, 1883 and Trabecula Dall & Bartsch, 1909 from Brazil are reviewed. Boonea jadisi (Olsson & McGinty, 1958), Boonea seminuda (C. B. Adams, 1839), Chrysallida gemmulosa C. B. Adams, 1850, Ivara terryi (Olsson & McGinty, 1958), Fargoa bushiana Bartsch, 1909, Mumiola gradatula (Mörch, 1876) and Odostomella carceralis Pimenta, Absalão & Alencar, 2000 are confirmed to occur in Brazil. We also present the first records of Parthenina varia (Odé, 1993), Odostomella fonteini (Jong & Coomans, 1988) and Trabecula krumpermanni (Jong & Coomans, 1988) from the region, all, new combinations. Two species, previously reported from the Brazilian coast, could not be confirmed: Boonea bisuturalis (Say, 1822) and Boonea impressa (Say, 1822). Odostomella cf. doliolum (Philippi, 1844) and Parthenina cf. interspatiosa (Linden & Eikenboom, 1992), originally described from the eastern Atlantic, are here recorded from Brazil, although their status remains dubious because of lack of information on their biology and due to lack of morphological and molecular data. One new species is described: Boonea scymnocelata, which can be distinguished from the similar species B. seminuda by its smaller size and immersed protoconch, with no visible nucleus.

Sequence data from the nuclear ribosomal internal transcribed spacer (ITS) region of 45 taxa were used to determine the phylogenetic relationship of Arabis arenicola to Arabis , Arabidopsis , Braya , and Eutrema , and that of Eutrema to the purportedly related genera Aphragmus , Lignariella , Neomartinella , Platycraspedum , Taphrospermum , and Thellungiella . Arabis arenicola was originally described as Eutrema in 1830, transferred to Arabis in 1898, and has remained in Arabis to the present, even though it is morphologically more similar to Arabidopsis, Braya, and Eutrema. Sequence data were obtained from representative taxa of Arabis, Arabidopsis, and related Boechera and Catolobus, Braya and Neotorularia, and Eutrema, Aphragmus, Lignariella, Neomartinella, Platycraspedum, Taphrospermum, and Thellungiella. The five Arabis arenicola accessions examined had ITS sequences that were identical to each other and to four Arabidopsis lyrata accessions. In both maximum parsimony and maximum likelihood analyses, Arabis arenicola fell within the Arabidopsis clade and was closely aligned with Arabidopsis lyrata. Two of six purportedly related genera were not closely related to Eutrema. Both analyses placed Lignariella within a separate well-supported clade with Aphragmus, while the other four genera, Neomartinella, Platycraspedum, Taphrospermum, and Thellungiella, fell within a well-supported clade with Eutrema. Morphology and molecular data strongly suggest transferring Arabis arenicola to Arabidopsis, expanding Aphragmus to include Lignariella, and expanding Eutrema to include Neomartinella, Platycraspedum, Taphrospermum, and Thellungiella. New combinations in Arabidopsis and Aphragmus are proposed.

Salacia comprises 200 species throughout the tropical countries. In Sri Lanka, five species of this genus S. chinensis, S. diandra, S. oblonga, S. reticulata and S. acuminatissima are recorded that are considered as the synonyms under S. diandra by Wadhwa in 1996 during the revision of genus. These species are very much similar in vegetative morphology and their flowering is irregular and rare. Due to these reasons, their proper identification and determination are difficult and identification of new combinations of taxonomic characters is necessary. A multivariate analysis was conducted for 98 distinct populations using 20 vegetative and 43 leaf anatomical characters including PCA, PCO, CA, SIMPER and correlation analysis. The results support the recognition of four phenetic groups, which corresponds to species S. chinensis, S. reticulata, S. oblonga and S. diandra. S. acuminatissima that was recognized by Kostermans (1992) was not supported by the analysis and formed a cluster together with S. diandra with no support as a separate cluster. The study failed to recognize any distinct vegetative characters to define these taxa but propose a combination of vegetative or leaf anatomical characters and also highlights the necessity of molecular data to supplement the vegetative and leaf anatomical data to resolve the ambiguity between the S. acuminatissima and S. diandra.

We describe 22 new species in the genus Hyphantrophaga Townsend, 1892 (Diptera: Tachinidae) from Area de Conservación Guanacaste (ACG) in north-western Costa Rica. All species were reared from an ongoing inventory of wild-caught caterpillars spanning a variety of families (Lepidoptera: Bombycidae, Crambidae, Depressariidae, Doidae, Erebidae, Euteliidae, Gelechiidae, Geometridae, Hedylidae, Hesperiidae, Immidae, Lasiocampidae, Limacodidae, Megalopygidae, Mimaloniidae, Noctuidae, Nolidae, Notodontidae, Nymphalidae, Papilionidae, Pieridae, Phiditiidae, Pterophoridae, Pyralidae, Riodinidae, Saturniidae, Sphingidae, Thyrididae, Tortricidae and Zygaenidae). We provide a morphological description of each species together with information on life history, molecular data and photographic documentation. In addition to the new species, we provide a redescription of the genus, as well as the redescription of three previously described species, which were also collected within ACG during this study: Hyphantrophagaangustata (van der Wulp), Hyphantrophagamyersi (Aldrich) and Hyphantrophagavirilis (Aldrich & Webber). The following 22 new species of Hyphantrophaga are described: Hyphantrophagaadrianguadamuzi Fleming & Wood sp. n., Hyphantrophagaalbopilosa Fleming & Wood sp. n., Hyphantrophagaanacordobae Fleming & Wood sp. n., Hyphantrophagacalixtomoragai Fleming & Wood sp. n., Hyphantrophagacalva Fleming & Wood sp. n.., Hyphantrophagaciriloumanai Fleming & Wood sp. n., Hyphantrophagadanausophaga Fleming & Wood sp. n., Hyphantrophagadiniamartinezae Fleming & Wood sp. n., Hyphantrophagaduniagarciae Fleming & Wood sp. n., Hyphantrophagaedwinapui Fleming & Wood sp. n., Hyphantrophagaeldaarayae Fleming & Wood sp. n., Hyphantrophagaeliethcantillanoe Fleming & Wood sp. n., Hyphantrophagagilberthampiei Fleming & Wood sp. n., Hyphantrophagaguillermopereirai Fleming & Wood sp. n., Hyphantrophagahazelcambroneroae Fleming & Wood sp. n., Hyphantrophagaluciariosae Fleming & Wood sp. n., Hyphantrophagamanuelriosi Fleming & Wood sp. n., Hyphantrophagamorphophaga Fleming & Wood sp. n., Hyphantrophaganigricauda Fleming & Wood sp. n., Hyphantrophagaosvaldoespinozai Fleming & Wood sp. n., Hyphantrophagapabloumanai Fleming & Wood sp. n. and Hyphantrophagasimilis Fleming & Wood sp. n. The following are proposed by Wood as new synonyms of Hyphantrophaga Townsend, 1892: Brachymasicera Townsend, 1911 syn. n., Ommasicera Townsend, 1911 syn. n., Ophirosturmia Townsend, 1911 syn. n., Patillalia Curran, 1934 syn. n. and Ypophaemyiops Townsend, 1935 syn. n. The following nine new combinations are proposed as a result of the new synonymies: Hyphantrophagaadamsoni (Thompson, 1963), comb. n., Hyphantrophagafasciata (Curran, 1934), comb. n., Hyphantrophagaglauca (Giglio-Tos, 1893), comb. n., Hyphantrophagagowdeyi (Curran, 1926), comb. n., Hyphantrophagamyersi (Aldrich, 1933), comb. n., Hyphantrophaganigripes (Townsend, 1928), comb. n., Hyphantrophagaoptica (Schiner, 1868), comb. n., Hyphantrophagapolita (Townsend, 1911), comb. n., Hyphantrophagasubpolita (Townsend, 1912), comb. n.

Taxonomic Studies

Abstract Sordariomycetes is an earlier and one of the widely distributed class of Ascomycota. The class was initially classified based on morphology in having inoperculate and unitunicate asci. With the development of DNA based phylogenetic analysis, several undetermined or polyphyletic members of Sordariomycetes were reclassified. However, not all species belonging to this class have been sequenced and analyzed. There are a number of species, especially those old and poorly studied ones which have never been sequenced before and not even recollected again for further taxonomic verification. One of the main objective in this study is to revise and update the taxonomy of several well-known old and poorly studied species whose classification are still obscure. Herein, we re-examined the type materials and/or authentic specimens together to explore 74 relatively poorly-studied genera, which mainly belong to Boliniales, Calosphaeriales, Chaetosphaeriales, Jobellisiales, and Sordariales classified under Diaporthomycetidae and Sordariomycetidae. We provide descriptions, notes, figures and/or drawings and discussed their phylogenetic relationships. As a result, the monotypic Jobellisiales is transferred from Hypocreomycetidae to Diaporthomycetidae. Based on phylogenetic analysis, the polyphyletic Lasiosphaeriaceae is divided into five families, Bombardiaceae (Apodospora, Bombardia, Bombardioidea and Fimetariella), Lasiosphaeriaceae (Anopodium, Bellojisia, Corylomyces, Lasiosphaeria, Mammaria and Zopfiella), Lasiosphaeridaceae (Lasiosphaeris), Strattoniaceae (Strattonia) and Zygospermellaceae (Episternus and Zygospermella). In addition, a new family Neoschizotheciaceae is established based on Neoschizothecium. Analysis of the type species of Boothiella, Stellatospora, Sulcatistroma and Tengiomyces placed them in Sordariaceae, Chaetomiaceae, Hypocreales and Coronophorales, respectively. We classify the genera lacking molecular data based on their morphology and expect them to be recollected; that is, Kacosphaeria in Calosphaeriales; Arnium, Biconiosporella, Camptosphaeria, Diffractella, Emblemospora, Eosphaeria, Periamphispora, Ramophialophora, Synaptospora and Tripterosporella in Sordariales; Conidiotheca in Sordariomycetes; Copromyces, Effetia, Endophragmiella and Tulipispora are accommodated in Ascomycota. Besides, we establish a new genus Neoschizothecium based on phylogenetic analysis. New combinations proposed include: Camaropella amorpha, Cam. microspora, Cam. plana, Cladorrhinum grandiusculum, Cla. leucotrichum, Cla. terricola, Cla. olerum, Helminthosphaeria plumbea, Immersiella hirta, Jugulospora minor, Lasiosphaeris arenicola, Neoschizothecium aloides, Neo. carpinicola, Neo. conicum, Neo. curvisporum, Neo. fimbriatum, Neo. glutinans, Neo. inaequale, Neo. minicaudum, Neo. selenosporum, Neo. tetrasporum, Neurospora autosteira, Podospora brunnescens, P. flexuosa, P. jamaicensis, P. hamata, P. macrospora, P. spinosa, Strattonia petrogale and Triangularia microsclerotigena, T. nannopodalis, T. praecox, T. samala, T. tarvisina, T. unicaudata, T. yaeyamensis. New epithets are proposed for Apiorhynchostoma apiosporum and Podospora dacryoidea.

The lichen family Teloschistaceae from the Galapagos is revised. Most of the species belong to the Caloplacoideae, two to Teloschistoideae and a few to Xanthorioideae, three subfamilies not validly published, which is remedied here. Four different datasets were analyzed using Bayesian inference. For the bulk of the species, a combined dataset of nrITS, nrLSU and mrSSU was analyzed. Additionally, three analyses were performed using nrITS to further investigate phylogenetic relationships within and between species in each subfamily, and in the genera Xanthomendoza and Squamulea. Four new genera are described: Lacrima, Oceanoplaca, Phaeoplaca, Sucioplaca. Twenty-four species are reported, of which ten are new to science: Caloplaca nigra, Lacrima galapagoensis, Oceanoplaca chemoisidiosa, O. sideritoides, Phaeoplaca tortuca, Squamulea chelonia, S. humboldtiana, S. osseophila, S. oceanica, and Xanthomendoza leoncita. Several new combinations are proposed and three species of Xanthomendoza are reduced to synonymy. Several new combinations and species placed into synonymy do not occur in the Galapagos, but are treated as a consequence of our taxonomic revision. Morphology, anatomy, secondary chemistry, distribution and molecular phylogenetic affiliation are presented for each species and a key is provided. Eight different chemical patterns are quantitatively described based on HPLC analyses. The new genus Lacrima includes L. galapagoensis, a species without vegetative propagules, and two densely isidiate species, L. epiphora and L. aphanotripta that are morphologically similar to ‘Caloplaca’ wrightii. The only species of Galapagos Teloschistaceae that contains xanthones is placed into Huneckia. Oceanoplaca includes two species with the new anthraquinone isidiosin, O. isidiosa and O. chemoisidiosa, while a third species, O. sideritoides, does not contain this secondary metabolite. Phaeoplaca camptidia has previously been reported from Galapagos, but our phylogenetic analysis suggests that it is a new species, here named P. tortuca. An isolated position is occupied by ‘Caloplaca’ diplacia, which we place in it its own monotypic genus Sucioplaca. Some Galapagos Teloschistaceae can be considered a ‘residue’ of unresolved Caloplaca s.l., i.e. the corticolous C. floridana is possibly related to the saxicolous C. nigra, while C. cupulifera can currently not be placed. Squamulea remains particularly problematic and includes S. phyllidizans, that is nested among otherwise unresolved Squamulea species. Based on molecular data, S. phyllidizans is close to ‘Huriella’. ‘Huriella’ flakusii, described from Peru, is confirmed to occur in the Galapagos and the genus is reduced to synonymy with Squamulea. The Squamulea squamosa/subsoluta group remains largely unresolved, but the new species S. chelonia, S. humboldtiana, S. oceanica, and S. osseophila are phylogenetically distinct. Foliose Teloschistaceae are represented only by one species, described as Xanthomendoza leoncita, while the only fruticose species, Teloschistes chrysophthalmus and T. flavicans, are cosmopolitan.
