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.

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 Iodosphaeriaceae is represented by the single genus, Iodosphaeria, which is composed of nine species with superficial, black, globose ascomata covered with long, flexuous, brown hairs projecting from the ascomata in a stellate fashion, unitunicate asci with an amyloid apical ring or ring lacking and ellipsoidal, ellipsoidal-fusiform or allantoid, hyaline, aseptate ascospores. Members of Iodosphaeria are infrequently found worldwide as saprobes on various hosts and a wide range of substrates. Only three species have been sequenced and included in phylogenetic analyses, but the type species, I. phyllophila, lacks sequence data. In order to stabilize the placement of the genus and family, an epitype for the type species was designated after obtaining ITS sequence data and conducting maximum likelihood and Bayesian phylogenetic analyses. Iodosphaeria foliicola occurring on overwintered Alnus sp. leaves is described as new. Five species in the genus form a well-supported monophyletic group, sister to the Pseudosporidesmiaceae in the Xylariales. Selenosporella-like and/or ceratosporium-like synasexual morphs were experimentally verified or found associated with ascomata of seven of the nine accepted species in the genus. Taxa included and excluded from Iodosphaeria are discussed.

Subfamilial Classification

A worldwide checklist is provided for the family Endomychidae (Coleoptera: Cucujoidea). An updated subfamilial classification is presented, based on recent higher-level phylogenetic analyses and incorporating many recently described taxa. At present, Endomychidae contains 1782 valid species and subspecies in 130 genera organized into 12 subfamilies. Two new synonyms are recognized: Symbiotes latus Redtenbacher, 1849 = Symbiotes latus var. roberti Falcoz & Roman, 1930 syn. nov.; and Cholovocerida Belon, 1884 = Displotera Reitter, 1887b syn. nov. Two new combinations are proposed: Cholovocerida ecitonis (Wasmann, 1890) for Coluocera ecitonis Wasmann, 1890 comb. nov.; and Cholovocerida maderae (Wollaston, 1854) for Cholovocera maderae Wollaston, 1854 comb. nov. Loeblia ceylanica Dajoz, 1972a is here designated as the type species for Loeblia Dajoz, 1972a, and Rhymbus hemisphaericus Gerstaecker, 1858 is designated as the type species for Rhymbus Gerstaecker, 1858. Nomen nudum status is proposed for Mycetaea tafilaletica Smirnoff, 1957. Thirty-two species originally described under Corynomalus Chevrolat, 1836 and subsequently transferred to Amphix Laporte, 1840, have been returned to Corynomalus. Known fossil taxa are summarized.

Balsam Poplar

Knufia endospora , a species described previously on the basis of cultured material, was found forming distinctive sporodochia on the bark of balsam poplar. Phylogenetic analyses of this fungus and some allied species indicated that (i) it forms a monophyletic group with Knufia cryptophialidica (type species of Knufia ) and with Coniosporium perforans , Coniosporium epidermidis and Phaeococcomyces chersonesos and (ii) P. chersonesos and Sarcinomyces petricola are conspecific. These Coniosporium and Phaeococcomyces species also shared major morphological characteristics with Knufia in culture and were morphologically and phylogenetically distant from the type species of their respective genera. The following new combinations are proposed: Knufia perforans (Sterflinger) Tsuneda, Hambleton & Currah; Knufia epidermidis (D.M. Li, de Hoog, Saunte & X.R. Chen) Tsuneda, Hambleton & Currah; and Knufia chersonesos (Bogom. & Minter) Tsuneda, Hambleton & Currah. Phaeococcomyces catenatus and Phaeococcomyces nigricans (type species of Phaeococcomyces) were morphologically similar but phylogenetically distant from each other and from Knufia.

Taxonomic Decision

Species in Angraecum sect. Dolabrifolia (Pfitzer 1889: 216) Garay (1973: 499) were assigned to several genera until Garay (1973) finally transferred the type species, A. distichum (Lindley 1836: t. 1781), along with A. podochiloides Schlechter (1906: 162) and A. aporoides Summerhayes (1964: 560) to Angraecum Bory (1804: 359) (see Simo-Droissart et al. 2016a). Later, Angraecum bancoense Burg in Arends et al. (1980: 26) and A. poppendickianum Szlachetko & Olszewski (2001: 884) were described and included in this section. According to Garay (1973), Angraecum sect. Dolabrifolia is characterized by very short, fleshy, laterally compressed and densely imbricate leaves, with a groove on the upper surface; the lateral compression being a unique feature within the genus. Based on this unique morphological character, Szlachetko and Romowicz (2007) raised the section to the rank of genus, Dolabrifolia (Pfitz.) Szlachetko & Romowicz (2007: 54) and proposed five new combinations, namely Dolabrifolia disticha (Lindl.) Szlachetko & Romowicz (2007: 54), D. aporoides (Summerh.) Szlachetko & Romowicz (2007: 54), D. bancoensis (Burg) Szlachetko & Romowicz (2007: 54), D. podochiloides (Schltr.) Szlachetko & Romowicz (2007: 54) and D. poppendickiana (Szlach. & Olszewski) Szlachetko & Romowicz (2007: 54). The taxonomic decision of Szlachetko and Romowicz (2007) was followed by Szlachetko et al. (2013), who also raised nine other Angraecum sections to the generic rank.

Here, based on phylogenetic analyses of 18 taxa and 57 morphological characters, we propose a new firefly genus, Costalampysgen. nov., to accommodate eleven species. Five new species are herein described: C. bellasp. nov., C. capixabasp. nov., C delicatasp. nov. (designated as type species), C. joanaesp. nov. and C. minimasp. nov. In addition, six species are redescribed and transferred from other genera: C. bisbinotata (Pic) comb. nov., transferred from Platylampis Motschulsky; C. decorata (Olivier) comb. nov., transferred from Ethra Laporte; C. pauper (Olivier) comb. nov., transferred from Cladodes Solier; as well as C. klugii (Motschulsky) comb. nov., C. quadriguttata (Gorham) comb. nov., and C. tricolor (Gorham) comb. nov., transferred from Lucidota Laporte. Costalampysgen. nov. is tentatively placed in Lampyrinae, and is diagnosed by: antennae with 11 articles, III–X basally flabellate, lacking dense and upright bristles; clypeus connected to frons by membrane, pygidium rounded; sternum VIII mucronate; phallus with dorsal plate enlarged apically, projecting ventrally and partially embracing the internal sac. Our phylogenetic analyses supported both the monophyly of Costalampysgen. nov. and the new combinations proposed. However, the relationship among congeneric species was poorly resolved. Finally, we provide illustrations of diagnostic features, distribution maps, as well as a key to Costalampysgen. nov. species, based on males.

Macrodiplodiopsis desmazieri, the type species of Macrodiplodiopsis, was collected from Italy, and morpho-molecular studies were carried out. Phylogenetic analyses (maximum-likelihood, maximum parsimony and Bayesian) using combined data set of LSU, SSU and EF1-α sequences showed our strain to group in Lophiostomataceae (Pleosporales) with Misturatosphaeria uniseriata and other Misturatosphaeria spp. Floricola striata, the type species of Floricola also groups in the same clade with a close relationship with Misturatosphaeria cruciformis. The Macrodiplodiopsis clade is well supported with high bootstrap and posterior probability. Floricola striata and nine species of Misturatosphaeria are transferred to the older name Macrodiplodiopsis as new combinations.

Abstract—Doellingeria and Eucephalus form the earliest-diverging clade of the North American Astereae lineage. Phylogenetic analyses of both nuclear and plastid sequence data show that the Doellingeria-Eucephalus clade consists of two main subclades that differ from current circumscriptions of the two genera. Doellingeria is the sister group to E. elegans, and the Doellingeria + E. elegans subclade in turn is sister to the subclade containing all remaining species of Eucephalus. In the plastid phylogeny, the two subclades are deeply divergent, a pattern that is consistent with an ancient hybridization event involving ancestral species of the Doellingeria-Eucephalus clade and an ancestral taxon of a related North American or South American group. Divergence of the two Doellingeria-Eucephalus subclades may have occurred in association with northward migration from South American ancestors. We combine these two genera under the older of the two names, Doellingeria, and propose 12 new combinations (10 species and two varieties) for all species of Eucephalus.

The genus Xylaplothrips is re-diagnosed, 11 species are listed as appropriately included in this genus of which three are new combinations from Haplothrips (X. acaciae; X. collyerae; X. gahniae). A further six species are listed as incertae sedis within Xylaplothrips and a key is provided to the four species of this genus known from Australia including X. anarsius sp.n. The genus Mesandrothrips is recalled from synonymy with Xylaplothrips, and a list is provided of 20 appropriately included species of which 14 are new combinations from Xylaplothrips (M. caliginosus; M. clavipes; M. darci; M. dubius; M. emineus; M. flavitibia; M. flavus; M. inquilinus; M. montanus; M. pictipes; M. pusillus; M. reedi; M. subterraneus; M. tener), and one is a new combination from Haplothrips (M. inquinatus). A key is provided to 10 species of this genus known from Australia, including three species transferred from Haplothrips, together with M. austrosteensia sp.n., M. googongi sp.n., M. kurandae sp.n., M. lamingtoni sp.n. and M. oleariae sp.n. The type species, M. inquilinus, is widespread across Southeast Asia as an invader of thrips galls, and Haplothrips darci Girault based on a single female from Queensland is considered closely related.

A revised generic synopsis of sub-Saharan Hyacinthaceae is presented, based on a molecular phylogenetic analysis of the family. Generic rank is accorded only to reciprocally monophyletic clades that can be distinguished by recognizable morphological discontinuities, thereby permitting an appropriate generic assignment of species not included in the analysis. Three subfamilies are recognized within the region. Subfamily Ornithogaloideae, characterized by flattened or angular seeds with tightly adhering testa, is considered to include the single genus Ornithogalum, which is expanded to include the genera Albuca, Dipcadi, Galtonia, Neopatersonia and Pseudogaltonia. Recognizing any of these segregates at generic level renders the genus Ornithogalum polyphyletic, while subdivision of Ornithogalum into smaller, morphologically distinguishable segregates in order to preserve the monophyly of each is not possible. Subfamily Urgineoideae, characterized by flattened or winged seeds with brittle, loosely adhering testa, comprises the two mainland African genera Bowiea and Drimia. The latter is well circumscribed by its deciduous, short-lived perianth and includes the previously recognized genera Litanthus, Rhadamanthus, Schizobasis and Tenicroa. The monotypic Madagascan Igidia is provisionally included in the subfamily as a third genus on the basis of its seeds, pending molecular confirmation of its relationships. Subfamily Hyacinthoideae resolves into three clades, distinguished as tribes Hyacintheae (strictly northern hemisphere and not treated further), Massonieae and Pseudoprospereae tribus nov. Full descriptions and a key to their identification are provided for all genera. New combinations reflecting the generic circumscriptions adopted here are made for most African and all Indian and Madagascan species.
