New and poorly known acrotretid brachiopods (Class Lingulata) from the Cedaria-Crepicephalus zone (late Middle Cambrian) of the Great Basin, USA

Seven new late Middle Cambrian (Cedaria-Crepicephalus zone) acrotretid species are described from the Great Basin, USA. The species belong to five genera of which Lensotreta is new. The following new species are described: Anabolotreta? glabra, Anabolotreta mogota, Canthylotreta crista, Dactylotreta elegantula, Lensotreta perplexa, Opisthotreta transversa, and Opisthotreta indistincta. The shell structure of Canthylotreta is described for the first time based on new material of the type species Canthylotreta marjumensis and of the new species C. crista. The shell of Canthylotreta includes two types of shell fabric, camerate and columnar. Moreover, parts of the shell show transitional textures, supporting the view that the camerate shell structure may has originated from a columnar fabric. Picnotreta lophocracenta Robson and Pratt, 2001, recently described from western Newfoundland, is also described from the new occurrence in the Great Basin.     

A new genus and species from Borneo and a new species from Java and Sumatra of Cicadini (Hemiptera: Cicadidae)

A new cicada genus and species, Minilomia triquetra, gen. and sp. nov., is described from Borneo. The new genus Minilomia is closely allied to Platylomia Stål and is placed in the subtribe Dundubiina of the tribe Cicadini. Another new cicada species, Pomponia brevicaudata, sp. nov. (subtribe Psithyristriina), is described from Java and Sumatra. The new species belongs to the Pomponia linearis species group and the P. linearis species complex but is distinguished from its congeners by the unusually short male abdomen.

A New Marine Species of Miracula (Oomycota) Parasitic to Minidiscus sp. in Iceland†

Obligate endoparasitic oomycetes are known to ubiquitously occur in marine and freshwater diatoms, but their diversity is still largely unexplored. Many of these parasitoids are members of the early-diverging oomycete lineages (Miracula, Diatomophthora), others are within the Leptomitales of the Saprolegniomycetes (Ectrogella, Lagenisma) and some have been described in the Peronosporomycetes (Aphanomycopsis, Lagenidium). Even though some species have been recently described and two new genera were introduced (Miracula and Diatomophthora), the phylogeny and taxonomy of most of these organisms remain unresolved. This is contrasted by the high number of sequences from unclassified species, as recently revealed from environmental sequencing, suggesting the presence of several undiscovered species. In this study, a new species of Miracula is reported from a marine centric diatom (Minidiscus sp.) isolated from Skagaströnd harbor in Northwest Iceland. The morphology and life cycle traits of this novel oomycete parasite are described herein, and its taxonomic placement within the genus Miracula is confirmed by molecular phylogeny. As it cannot be assigned to any previously described species, it is introduced as Miracula islandica in this study. The genus Miracula thus contains three described holocarpic species (M. helgolandica, M. islandica, M. moenusica) to which likely additional species will need to be added in the future, considering the presence of several lineages known only from environmental sequencing that clustered within the Miracula clade.     

Opegrapha cladoniicola,a new lichenicolous fungus from Hawaii

Morphological and phylogenetic studies of Cytospora (Valsaceae,Diaporthales) isolates from Chinese scholar tree,with description of a new species

Cytospora species are the most serious and widespread pathogens associated with canker disease on multiple plants. In this study, three species, i.e., Cytospora sophoricola, C. chrysosperma, and C. sophorae, which were isolated from Sophora in China, are described and illustrated based on their morphological characteristics and phylogenetic analyses. Cytospora sophoricola was distinguished clearly by its larger disc, multiple ostioles, cystic and multiple locules, and specific cultural characteristics, i.e., protruding fruiting bodies. Maximum parsimony and maximum likelihood analysis showed that it did not cluster with any known species of Cytospora, so it is described as a new species. Cytospora sophorae is a previously reported species from Sophora, which is redescribed based on new isolates and additional observations. Another species was identified as C. chrysosperma, which is reported for the first time on Sophora, so Papilionaceae is shown to be a new host family for C. chrysosperma. The morphological affinities of these species with related taxa are discussed, while the phylogenetic relationships of these species with other fungus in the genus Cytospora were elucidated based on their internal transcribed spacer (ITS) rRNA region sequences.

The juvenile external morphology of P. panoplus is described and illustrated. A lectotype of P. pakistanensis is designated and the two species compared, and the dissimilar nature of cuticular tubercles in Bunonema and Rhodolaimus is discussed.     

Two newly recognized species of Hemidactylus (Squamata,Gekkonidae) from the Arabian Peninsula?and Sinai,Egypt

A recent molecular phylogeny of the Arid clade of the genus Hemidactylus revealed that the recently described H. saba and two unnamed Hemidactylus species from Sinai, Saudi Arabia and Yemen form a well-supported monophyletic group within the Arabian radiation of the genus. The name ‘Hemidactylus saba species group’ is suggested for this clade. According to the results of morphological comparisons and the molecular analyses using two mitochondrial (12S and cytb) and four nuclear (cmos, mc1r, rag1, rag2) genes, the name Hemidactylus granosus Heyden, 1827 is resurrected from the synonymy of H. turcicus for the Sinai and Saudi Arabian species. The third species of this group from Yemen is described formally as a new species H. ulii sp. n. The phylogenetic relationships of the members of ‘Hemidactylus saba species group’ are evaluated and the distribution and ecology of individual species are discussed.     

A new species and a new record of Helicomyces from Taiwan

Helicomyces geniculatus sp. nov. from decaying wood submerged in a freshwater stream at Juchi Town of Alishan area, Chiayi County, Taiwan, is described and illustrated. It differs from other Helicomyces species in having geniculate conidiophores arising from repent hyphae and also borne on erect setae. Abundant stalked sclerotia were also found in this species. Helicomyces torquatus is described in this paper as a new record for Taiwan, with new observation. The phylogenetic relationship of H. geniculatus, H. torquatus, and related taxa were sought by comparing the sequences of their ITS barcode of the nuc rDNA. A synopsis of the 13 accepted Helicomyces species is given.     

The Sharpshooter Genus Geitogonalia Young: Descriptions of a New Brazilian Species and of the Female of Geitogonalia quatuordecimmaculata (Taschenberg) (Hemiptera: Cicadellidae)

The sharpshooter genus Geitogonalia Young was so far known from a single species from Southeastern Brasil—Geitogonalia quatuordecimmaculata (Taschenberg). A new species, Geitogonalia viridis, is described and illustrated in this paper based on males and females from the state of Rio de Janeiro. In addition, the female of G. quatuordecimmaculata is for the first time described and illustrated in detail. Geitogonalia quatuordecimmaculata is a dark species marked with bright orange on the fore wings, whereas the new species has the corium and clavus of the fore wings mostly green. The paraphyses are well developed in G. quatuordecimmaculata, with elongate rami, whereas they are inconspicuous in G. viridis, with the rami modified as a pair of very small sclerites.
